A multinational corporation must comply with GDPR and requires that data stored in BigQuery is physically located in the European Union. They have set up BigQuery datasets in the EU region. However, a compliance audit reveals that some queries may process data in the US region due to BigQuery's multi-region behavior. What should the organization do to ensure data remains in the EU?

A.Create BigQuery datasets in a specific European region (e.g., europe-west1) instead of the EU multi-region.

B.Use the EU multi-region dataset and configure VPC Service Controls to restrict access.

C.Enable BigQuery CMEK with keys stored in a European Cloud KMS key ring.

D.Use BigQuery reservations to guarantee that data processing happens in the EU.

AnswerA

Single-region datasets keep data and processing within that region.

Why this answer

Option A is correct because creating a BigQuery dataset in a specific European region (e.g., europe-west1) ensures that all data storage and query processing are physically confined to that single region. In contrast, the EU multi-region (EU) is a geographic entity that includes multiple Google Cloud regions within the European Union, and BigQuery may process data in any of those regions, including potentially outside the EU if the multi-region expands. By using a specific regional dataset, the organization guarantees that data never leaves the designated European location, meeting GDPR's data residency requirements.

Exam trap

Google Cloud often tests the misconception that VPC Service Controls or encryption keys can enforce data residency, but the trap here is that only choosing a specific regional dataset (not a multi-region) physically restricts data processing to a single location.

How to eliminate wrong answers

Option B is wrong because VPC Service Controls restrict network access to resources but do not control the physical location where data is processed; they cannot prevent BigQuery from processing data in a different region within a multi-region. Option C is wrong because Customer-Managed Encryption Keys (CMEK) control encryption at rest but have no impact on where data is processed or stored; the key location does not enforce data residency. Option D is wrong because BigQuery reservations manage slot capacity and query priority, not the geographic location of data processing; they cannot force processing to occur in a specific region.

Which THREE steps are necessary to meet SOC 2 Type II requirements using Google Cloud?

Select 3 answers

A.Enable Cloud Audit Logs and retain them for at least one year.

B.Ensure all data in transit is encrypted using TLS.

C.Use a single Google Cloud project for all data to simplify auditing.

D.Use Customer-Managed Encryption Keys (CMEK) for all storage services.

E.Set up Cloud Monitoring alerts to continuously monitor security configurations.

AnswersA, B, E

Audit logs provide evidence of controls and are required for SOC 2.

Why this answer

Option A is correct because SOC 2 Type II requires evidence of continuous monitoring and retention of audit logs for at least one year to demonstrate effective controls. Enabling Cloud Audit Logs in Google Cloud captures admin activity, data access, and system events, which are essential for audit evidence. Retaining these logs for a minimum of one year aligns with the SOC 2 common criteria for monitoring and response.

Exam trap

Google Cloud often tests the misconception that using a single project simplifies compliance, when in reality SOC 2 requires logical separation and least privilege, which is better achieved with multiple projects or folders; also, candidates may assume CMEK is mandatory for encryption, but Google-managed keys are acceptable for SOC 2.

MCQeasy

A company wants to grant a third-party auditor read-only access to specific BigQuery datasets in a project. The auditor's identity is managed in their own Google Cloud organization. What is the most secure way to grant access?

A.Share the project's service account key with the auditor so they can impersonate it.

B.Use VPC Service Controls to allow access only from the auditor's IP range.

C.Create a service account in the company's project, grant it the BigQuery Data Viewer role, and allow the auditor's organization to use that service account via Workload Identity Federation.

D.Create a Google Group and add the auditor's email addresses, then grant the group the BigQuery Data Viewer role.

AnswerC

Workload Identity Federation allows secure cross-organization access without managing external identities.

Why this answer

Option C is correct because it uses Workload Identity Federation to allow the auditor's Google Cloud organization to impersonate a service account in the company's project without sharing a key. This grants read-only access via the BigQuery Data Viewer role while eliminating the risk of long-lived credentials. The auditor's identity is managed externally, and access is granted through a secure, federated trust relationship.

Exam trap

Google Cloud often tests the misconception that sharing a service account key is acceptable for cross-organization access, when in fact Workload Identity Federation is the secure, keyless alternative designed for this exact scenario.

How to eliminate wrong answers

Option A is wrong because sharing a service account key exposes a long-lived, unrotatable credential that violates the principle of least privilege and can be misused or leaked. Option B is wrong because VPC Service Controls restrict network access but do not authenticate the auditor's identity or grant granular dataset-level permissions; they are a perimeter control, not an identity-based access solution. Option D is wrong because adding the auditor's email addresses to a Google Group assumes the auditor's identities are managed within the same Google Cloud organization or as Google Accounts, which is not the case here; external identities cannot be added directly to a Google Group without federation.

Your VPC has a default firewall rule that allows SSH (TCP port 22) from all sources. You need to allow HTTP traffic (TCP port 80) only from instances tagged 'web-servers' to the target instances, and block all other inbound traffic including SSH. Which TWO steps should you take?

Select 2 answers

A.Modify the default-allow-ssh rule to set its source filter to an empty range.

B.Create a firewall rule with priority 65535 allowing all traffic from 0.0.0.0/0.

C.Delete the default-allow-ssh rule.

D.Create a firewall rule with priority 1000 allowing ingress from instances with tag 'web-servers' on TCP port 80.

E.Create a firewall rule with priority 1000 allowing ingress from instances with tag 'web-servers' on TCP port 443.

AnswersC, D

This removes the default allow for SSH, which is necessary to block SSH traffic.

Why this answer

Option C is correct because deleting the default-allow-ssh rule removes the rule that permits SSH from all sources (0.0.0.0/0), which is necessary to block all inbound SSH traffic as required. Option D is correct because creating a firewall rule with priority 1000 that allows ingress on TCP port 80 from instances tagged 'web-servers' explicitly permits HTTP traffic only from the desired source, and since lower priority numbers are evaluated first, this rule will be applied before any higher-numbered (lower priority) default rules.

Exam trap

Google Cloud often tests the misconception that you can simply modify or override a default rule by adding a higher-priority deny rule, but in Google Cloud VPC, firewall rules are allow-only (no explicit deny rules), so the only way to block traffic allowed by a default rule is to delete that rule or change its source filter to a non-matching range.

MCQmedium

During an incident, a security engineer needs to isolate a compromised Compute Engine instance for forensic analysis without losing evidence. What should they do first?

A.Disconnect the instance from the VPC network.

B.Shut down the instance immediately.

C.Delete the instance to prevent further damage.

D.Create a snapshot of the instance's persistent disks.

AnswerD

Snapshots capture disk data for later analysis without altering the instance.

Why this answer

Option B is correct because taking a snapshot of the persistent disks preserves the disk state for forensic analysis without altering the instance. Option A may cause loss of volatile data but is acceptable; however, snapshot is the recommended first step to capture data. Option C disconnects the instance but may not prevent further damage.

Option D destroys evidence.

MCQeasy

A company in the EU is moving to Google Cloud and must comply with GDPR data residency requirements. They have users across multiple EU countries and want to ensure that personal data remains within the European Economic Area (EEA). They plan to use Cloud Storage, BigQuery, and Compute Engine. The security administrator sets organization policies to restrict resource locations to europe-west1, europe-west3, and europe-west4. After deploying applications, the compliance team finds that some data is stored in a Cloud Storage bucket in us-central1. Investigation shows that the bucket was created by a developer who manually chose the region. The organization policy seems to have been bypassed. The administrator confirms the policy is active and applied to the project. What is the most likely cause?

A.The policy only applies to Compute Engine resources, not Cloud Storage.

B.The organization policy was set at the folder level, and the project where the bucket was created is not a child of that folder.

C.The developer has the orgpolicy.policyCreator role, which allows them to bypass the policy.

D.The policy was set to allowlist mode, and us-central1 is in the allowlist.

AnswerB

Organization policies are hierarchical; if the project is not under the folder where the policy is set, it is not enforced.

Why this answer

Organization policies in Google Cloud are hierarchical and apply only to resources within the scope of the node (organization, folder, or project) where they are set. If the policy is set at a folder level, it does not affect projects that are not children of that folder. In this scenario, the bucket was created in a project outside the folder hierarchy where the policy was applied, so the policy was not enforced on that project, allowing the developer to choose us-central1.

Exam trap

Google Cloud often tests the hierarchical nature of organization policies, and the trap here is that candidates assume a policy set at any level applies to all projects in the organization, ignoring that it only applies to projects within the specific folder or node where the policy is attached.

How to eliminate wrong answers

Option A is wrong because organization policies for resource location (constraints/gcp.resourceLocations) apply to Compute Engine, Cloud Storage, BigQuery, and many other services, not just Compute Engine. Option C is wrong because the orgpolicy.policyCreator role allows a user to create and manage organization policies, but it does not grant the ability to bypass an active policy; policies are enforced regardless of the creator's role. Option D is wrong because the policy was set to restrict locations to europe-west1, europe-west3, and europe-west4, which is a deny-list (restrict) mode, not an allowlist mode; if it were an allowlist, us-central1 would not be in the allowed set.

MCQhard

A security engineer needs to protect sensitive data in BigQuery. The data includes columns with personally identifiable information (PII). They want to automatically mask PII data for users with the role 'analyst' but allow full access for 'admin' users. Which approach should they use?

A.Use VPC Service Controls to restrict access to the dataset.

B.Create authorized views that exclude PII columns for the analyst role.

C.Use column-level access control via IAM roles to deny access to PII columns for analysts.

D.Apply policy tags with data masking policies to PII columns and assign the tag to the analyst role.

AnswerD

Policy tags with masking policies can dynamically mask data based on user's role.

Why this answer

Option D is correct because BigQuery's policy tags with data masking policies allow you to automatically mask sensitive columns (e.g., PII) at query time based on the user's role. You assign a masking policy to the policy tag, then attach that tag to the PII columns. By granting the 'analyst' role access to the tag with the masking rule applied, analysts see masked data, while 'admin' users (who have higher-level IAM permissions) see the full data without additional configuration.

Exam trap

Google Cloud often tests the distinction between column-level access control (which can only hide or deny columns) and data masking (which can partially obscure data while still allowing access), leading candidates to mistakenly choose option C.

How to eliminate wrong answers

Option A is wrong because VPC Service Controls restrict network-level access to the BigQuery API but do not provide column-level data masking or role-based masking of PII. Option B is wrong because authorized views require creating separate views for each dataset and manually maintaining them; they do not automatically mask data at query time for different roles within the same table, and they add administrative overhead. Option C is wrong because column-level access control via IAM roles can only deny access to entire columns (making them invisible or causing errors), not mask the data; it cannot show partially masked values to analysts while allowing full access to admins.

MCQeasy

A security engineer needs to ensure that a Compute Engine VM can securely access Cloud Storage buckets without exposing a public IP address. The VM is in a VPC with Private Google Access enabled. What is the recommended approach?

A.No additional configuration is needed; Private Google Access allows access to Cloud Storage from VMs without external IPs.

B.Deploy a Squid proxy in the same VPC and configure the VM to use it for all outbound traffic.

C.Assign an external IP to the VM and configure a firewall rule to allow egress to 0.0.0.0/0.

D.Configure Cloud NAT and ensure the VM has a route to the internet.

AnswerA

Correct: Private Google Access enables access to Google APIs via internal IPs.

Why this answer

Private Google Access enables a VM without an external IP address to reach Google APIs and services, including Cloud Storage, using the VPC's internal IP and Google's private network. Since the VM is in a VPC with Private Google Access enabled, it can securely access Cloud Storage buckets without needing a public IP or additional proxy. No further configuration is required because the traffic stays within Google's network and never traverses the public internet.

Exam trap

Google Cloud often tests the misconception that Private Google Access requires an external IP or NAT, but the trap here is that Private Google Access is specifically designed for VMs without external IPs to access Google APIs and services directly, so no additional components like proxies or NAT are needed.

How to eliminate wrong answers

Option B is wrong because a Squid proxy is unnecessary and adds complexity; Private Google Access already provides direct private connectivity to Cloud Storage without a proxy. Option C is wrong because assigning an external IP and allowing egress to 0.0.0.0/0 exposes the VM to the public internet, violating the requirement to avoid a public IP. Option D is wrong because Cloud NAT is used for outbound internet access from private VMs, but Private Google Access already handles access to Google APIs and services like Cloud Storage without needing NAT or internet routing.

A security engineer is troubleshooting access to a Cloud Storage bucket. The bucket has uniform bucket-level access enabled. The engineer's user account has the roles/storage.objectViewer role at the project level, but they get a 403 error when trying to download an object. What is the most likely cause?

A.The bucket has ACLs that override the IAM role.

B.The user does not have the storage.objects.get permission.

C.The user's project-level role does not apply to this specific bucket.

D.There is a deny rule in an Organization Policy or an IAM deny policy that blocks the user.

AnswerD

Deny rules take precedence over allow rules, causing the 403 error.

Why this answer

Option D is correct because uniform bucket-level access disables ACLs, so access is governed solely by IAM and organization policies. A deny rule in an Organization Policy or an IAM deny policy explicitly overrides any allow permissions, causing a 403 error even if the user has the roles/storage.objectViewer role at the project level. This is the most likely cause given that the user already has the necessary IAM role.

Exam trap

Google Cloud often tests the nuance that deny policies (IAM deny or Organization Policy) override allow policies, leading candidates to incorrectly assume that having the correct IAM role is sufficient for access.

How to eliminate wrong answers

Option A is wrong because uniform bucket-level access disables ACLs on the bucket, so ACLs cannot override IAM roles. Option B is wrong because the roles/storage.objectViewer role includes the storage.objects.get permission, which is sufficient to download objects. Option C is wrong because project-level IAM roles apply to all buckets in the project when uniform bucket-level access is enabled, so the role does apply to this specific bucket.

MCQeasy

A company wants to monitor for suspicious login attempts across all their Google Cloud projects. They want to send a real-time Slack notification when a login fails from an IP address outside their corporate CIDR range. What is the most efficient way to achieve this?

A.Create a Cloud Monitoring alert policy that checks for failed logins in logs and sends a notification to Slack via webhook.

B.Use Cloud Scheduler to run a batch job every hour that queries logs and sends a summary to Slack.

C.Export Admin Activity audit logs to a Pub/Sub topic via a sink, and use a Cloud Function that subscribes to the topic to filter and post to Slack.

D.Enable Cloud Audit Logs and configure a log router to forward logs directly to Slack.

AnswerC

This provides real-time, scalable, and customizable notification.

Why this answer

Option A is correct because Admin Activity audit logs capture login events, and a Cloud Logging sink to Pub/Sub enables real-time streaming to a Cloud Function that posts to Slack. Option B is incorrect because Cloud Monitoring does not directly analyze audit logs. Option C is incorrect because Cloud Scheduler would not provide real-time response.

Option D is incorrect because Cloud Audit Logs alone cannot send Slack notifications.

MCQhard

Refer to the exhibit. A security engineer runs the command to view recent decrypt operations on a Cloud KMS key. The output shows a successful decryption. However, the engineer is concerned about the exposure of the plaintext. Based on the log entry, what is the most accurate statement regarding the visibility of the decrypted plaintext?

A.The plaintext field is not present in the log because the service does not log it.

B.The plaintext field contains the base64-encoded ciphertext, and the engineer needs to decode it.

C.The plaintext field is redacted by Cloud KMS, and the actual plaintext is not visible in the log entry.

D.The plaintext field contains the actual decrypted data in plaintext, and the engineer should restrict access to the logs.

AnswerC

Cloud Audit Logs automatically redact sensitive data like decrypted plaintext.

Why this answer

Option C is correct because Cloud KMS automatically redacts the plaintext field in Cloud Audit Logs for decrypt operations. The log entry shows a successful decryption, but the actual decrypted data is never written to the logs; instead, the plaintext field is replaced with a redacted marker (e.g., `[REDACTED]`). This is a security feature to prevent sensitive data from being exposed in audit logs, even to users with access to view them.

Exam trap

Google Cloud often tests the misconception that the plaintext field in Cloud KMS logs contains the actual decrypted data or that it is simply absent, when in fact it is explicitly redacted to protect sensitive information.

How to eliminate wrong answers

Option A is wrong because the plaintext field is present in the log entry (as shown in the exhibit), but it is redacted, not absent; the service does log the field but explicitly omits the actual plaintext. Option B is wrong because the plaintext field does not contain base64-encoded ciphertext; it contains a redacted value, and the engineer does not need to decode anything—the ciphertext is a separate field in the log. Option D is wrong because the plaintext field does not contain the actual decrypted data; Cloud KMS ensures the plaintext is never exposed in logs, so restricting access to logs would not address the concern about plaintext visibility.

An organization wants to enforce that all IAM policy changes in their Google Cloud organization are logged and require approval. Which three Google Cloud capabilities can help achieve this? (Choose THREE.)

Select 3 answers

A.Cloud Run for Anthos

B.Organization policies with constraints

C.Cloud Asset Inventory with Cloud Pub/Sub notifications

D.VPC Service Controls

E.Cloud Audit Logs

AnswersB, C, E

Policies like constraints/iam.allowedPolicyMemberDomains restrict who can be granted roles.

Why this answer

Organization policies with constraints (B) allow you to define and enforce guardrails for IAM policy changes, such as using the `iam.policyServiceAccountKeyExpiryHours` constraint to require approval workflows via the Access Approval API. Cloud Asset Inventory with Cloud Pub/Sub notifications (C) can monitor and stream real-time updates to IAM policies, triggering approval processes. Cloud Audit Logs (E) record all IAM policy changes, providing an immutable audit trail that can be used to verify compliance and enforce approval requirements.

Exam trap

Google Cloud often tests the distinction between monitoring/logging services (Cloud Audit Logs, Cloud Asset Inventory) and security enforcement tools (Organization policies, VPC Service Controls), leading candidates to mistakenly select VPC Service Controls for IAM change approval instead of recognizing it as a data exfiltration prevention mechanism.

A company has two Google Cloud projects: Project A (production) and Project B (development). They want to allow a service account in Project B to list Compute Engine instances in Project A. What is the most secure way to grant this access?

A.Create a new service account in Project A, generate a key, and share it with the application in Project B.

B.Add the service account as a member in Project A's IAM policy with the roles/compute.viewer role.

C.Make the service account a project owner of Project A.

D.Export the service account key from Project B and use it in an application in Project A.

AnswerB

This grants only the necessary permissions to the service account without exposing credentials.

Why this answer

Option B is correct because it uses IAM to grant the service account from Project B the roles/compute.viewer role on Project A, which allows it to list Compute Engine instances without sharing keys or granting excessive permissions. This follows the principle of least privilege and avoids the security risks of key management.

Exam trap

The trap here is that candidates often think service accounts can only access resources within their own project, or they mistakenly believe that sharing keys is the only way to grant cross-project access, ignoring IAM's ability to grant roles to principals from other projects.

How to eliminate wrong answers

Option A is wrong because creating a new service account in Project A and sharing its key with Project B introduces a long-lived credential that can be leaked or misused, violating security best practices. Option C is wrong because making the service account a project owner of Project A grants it full administrative access, far beyond the needed read-only permission to list instances, which is insecure. Option D is wrong because exporting the service account key from Project B and using it in Project A does not grant access to Project A's resources; the key authenticates the service account in Project B, which has no permissions in Project A unless explicitly granted via IAM.

An organization uses Shared VPC to centrally manage network resources. They want to allow a service project to use its own firewall rules for certain instances. How should they configure the firewall rules?

A.Firewall rules can only be created in the host project

B.Create firewall rules in the service project with target tags

C.Create firewall rules in the host project with target tags for service project instances

D.Use hierarchical firewall policies

AnswerA

In Shared VPC, the host project owns the VPC network and all firewall rules must be defined there.

Why this answer

In Shared VPC, all firewall rules are created in the host project. Service projects cannot create firewall rules for the shared VPC network. Therefore, the only way is to create rules in the host project.

A company uses Access Context Manager to restrict access to Cloud Resources based on device policy. They want to allow access only from devices that are company-managed and have disk encryption enabled. What should they configure?

A.Create an IAM condition requiring a specific device tag.

B.Use Identity-Aware Proxy with device policy.

C.Create an access level with device policy conditions for corporate-owned and disk encryption.

D.Use VPC Service Controls with a device restriction.

AnswerC

Access Context Manager supports these conditions.

Why this answer

Option C is correct because Access Context Manager allows you to create access levels that define device policy conditions, such as requiring devices to be corporate-owned and have disk encryption enabled. These access levels are then applied to the organization's access policies to restrict access to cloud resources based on the device's compliance status.

Exam trap

The trap here is that candidates often confuse the roles of IAM conditions, IAP, and VPC Service Controls, mistakenly thinking they can enforce device-level policies directly, when in fact Access Context Manager is the dedicated service for such fine-grained device policy enforcement.

How to eliminate wrong answers

Option A is wrong because IAM conditions cannot directly evaluate device policy attributes like disk encryption; they are used for attribute-based access control (ABAC) on resource and principal attributes, not device compliance. Option B is wrong because Identity-Aware Proxy (IAP) enforces access based on identity and context, but it does not natively check device-level policies like disk encryption; it relies on Access Context Manager for such conditions. Option D is wrong because VPC Service Controls are designed to prevent data exfiltration by controlling the perimeter around Google Cloud services, not to enforce device-level policies like corporate ownership or disk encryption.

MCQhard

A financial services company runs a sensitive application on Google Kubernetes Engine (GKE) with Workload Identity enabled. Security policy requires that only pods with a specific service account can access a Cloud Storage bucket containing customer data. The bucket has uniform bucket-level access enabled. What is the correct combination of IAM bindings to achieve this?

A.Add the Google service account as a member of the bucket with roles/storage.objectViewer

B.Bind the Google service account (linked to the Kubernetes service account via Workload Identity) to the bucket IAM policy with roles/storage.objectViewer

C.Grant the Google service account roles/storage.objectViewer at the project level

D.Bind the Kubernetes service account to the bucket IAM policy with roles/storage.objectViewer

AnswerB

This is the correct approach: the GSA is granted the role, and pods using the mapped KSA inherit that access.

Why this answer

Workload Identity links a Kubernetes service account (KSA) to a Google service account (GSA). When a pod uses that KSA, it authenticates as the linked GSA. Since the bucket has uniform bucket-level access, IAM permissions must be granted directly on the bucket resource, not at the project level.

Binding the GSA to the bucket with roles/storage.objectViewer ensures only pods using that specific KSA can read the bucket.

Exam trap

Google Cloud often tests the distinction between Kubernetes service accounts and Google service accounts, trapping candidates who try to bind a KSA directly to a Google Cloud resource instead of using the linked GSA via Workload Identity.

How to eliminate wrong answers

Option A is wrong because it says 'Add the Google service account as a member of the bucket' but does not specify the correct IAM role binding on the bucket resource; it is vague and incomplete. Option C is wrong because granting roles/storage.objectViewer at the project level would allow any workload or user with that role to access the bucket, violating the security policy that restricts access to only pods with a specific service account. Option D is wrong because Kubernetes service accounts are not recognized by Cloud Storage IAM; only Google service accounts can be bound to bucket IAM policies, and Workload Identity provides the mapping.

A financial services company wants to ensure that Google Cloud staff cannot access their encryption keys or the plaintext data. They must meet regulatory requirements for data sovereignty. Which combination of services should they use?

A.Use CMEK with Cloud HSM and disable Access Transparency.

B.Use Customer-Supplied Encryption Keys (CSEK) without Access Transparency.

C.Use Cloud External Key Manager and enable Access Transparency logs.

D.Use VPC Service Controls and Cloud DLP.

AnswerC

EKM keeps keys outside Google; Access Transparency monitors access.

Why this answer

Option C is correct because Cloud External Key Manager (EKM) allows you to manage encryption keys using a supported external key management partner, ensuring that Google Cloud staff cannot access your keys or plaintext data. Enabling Access Transparency logs provides you with logs of Google Cloud staff access to your data, which helps meet regulatory requirements for data sovereignty by giving you visibility into administrative actions.

Exam trap

Google Cloud often tests the distinction between key management options (CMEK, CSEK, EKM) and the role of Access Transparency, leading candidates to confuse CMEK (which still gives Google control over key material) with EKM (which keeps keys external).

How to eliminate wrong answers

Option A is wrong because CMEK with Cloud HSM still allows Google Cloud to manage the key material (though in a hardware security module), and disabling Access Transparency removes visibility into Google staff access, failing the requirement that Google Cloud staff cannot access keys or plaintext. Option B is wrong because Customer-Supplied Encryption Keys (CSEK) are only supported for a limited set of Google Cloud services (Compute Engine and Cloud Storage) and do not prevent Google Cloud staff from accessing the keys during processing; also, disabling Access Transparency eliminates audit logs needed for sovereignty compliance. Option D is wrong because VPC Service Controls and Cloud DLP control network access and data loss prevention, respectively, but do not address encryption key management or prevent Google Cloud staff from accessing keys or plaintext data.

Which THREE steps are most effective for troubleshooting a VPC firewall rule issue where desired traffic is being blocked?

Select 3 answers

A.Check IAM permissions for the VM's service account

B.Check firewall rule logs in Cloud Logging

C.Verify that the network tags on instances match the target tags in the firewall rule

D.Review VPC flow logs to see if traffic is reaching the VM

E.Inspect the route tables for the subnet

AnswersB, C, D

Firewall logs show allowed and denied connections, directly indicating blocking.

Why this answer

Options A, B, and D are correct. Checking firewall logs reveals denied traffic. Verifying network tags ensures instances match the target tags.

Reviewing VPC flow logs shows actual traffic flows. Option C (check IAM permissions) is less relevant because firewall rules are network-level, not identity-based. Option E (inspect route tables) affects routing, not firewall blocking.

A company is designing a CI/CD pipeline using Cloud Build. Security requirements mandate that the pipeline deploy only to projects that have been explicitly authorized. The security team wants to use a service account that can be assumed by Cloud Build to perform deployments, and they want to restrict which projects can be deployed to using organization policies. Which approach should they take?

A.Use the organization policy constraint 'constraints/iam.serviceAccountKeyExpiryHours' to force key rotation.

B.Use the organization policy constraint 'constraints/iam.allowedPolicyMemberDomains' and set it to only allow the service account's domain.

C.Use the organization policy constraint 'constraints/compute.restrictCrossProjectNw' to limit network access.

D.Use the organization policy constraint 'constraints/iam.workloadIdentityPoolProviders' to restrict which workload identity pools can be used.

Why this answer

Option A is correct because the constraint 'constraints/iam.allowedPolicyMemberDomains' can be used to restrict the set of principals that can be granted roles, but it does not restrict which projects service accounts can be used in. The correct approach is to use the constraint 'constraints/iam.workloadIdentityPoolProviders' or similar to restrict the identity, but more directly, using a service account and granting it roles only in authorized projects, combined with organization policy to restrict cross-project service account usage, is not fully covered by the given options. Actually, the best practice is to use a service account per environment and use organization policy 'constraints/iam.allowedPolicyMemberDomains' to restrict which identities can be granted roles, but for service account usage, the correct answer is to use the 'iam.serviceAccountKeyExpiryHours' constraint? No.

Re-evaluating: The question is about restricting which projects the pipeline can deploy to. Option A: Use organization policy 'constraints/iam.gcpPrincipal'? Not a real constraint. Option B: Use organization policy 'constraints/iam.serviceAccountKeyExpiryHours' is about key expiry.

Option C: Use organization policy 'constraints/compute.restrictCrossProjectNw' is network-related. Option D: Use organization policy 'constraints/iam.workloadIdentityPoolProviders' is for workload identity federation. The correct way is to use the service account and grant it deployment roles only in allowed projects, and use organization policy 'constraints/iam.allowedPolicyMemberDomains' to restrict which identities can be granted roles? That doesn't restrict which projects.

Actually, the standard way is to use the 'iam.allowedPolicyMemberDomains' constraint to restrict which domains' principals can be granted roles, but that's for identities. Another approach is to use the 'Compute Engine service account' constraint? Hmm. The best answer among the options is likely D because workload identity pools can be used to restrict which external identities can impersonate, but that doesn't fit.

Let's reconsider: The question might be about using a service account per project and using organization policy to prevent the service account from being used in other projects via 'iam.disableServiceAccountCreation'? No. Actually, the correct answer is not listed explicitly, but among the options, the one that is most relevant is 'constraints/iam.workloadIdentityPoolProviders'? That's for external identities. I think the intended correct answer is to use 'constraints/iam.allowedPolicyMemberDomains' (not listed) but option A is 'constraints/iam.gcpPrincipal' which is not real.

Option C is 'constraints/compute.restrictCrossProjectNw' which is network. Option B is about key expiry. So none are correct? This is a flawed question.

A company is designing a network architecture for a multi-region application. They want to minimize latency and maximize availability. Which two features should they consider? (Choose two.)

Select 2 answers

A.Cloud NAT

B.Cloud CDN

C.Cloud Interconnect

D.Global Cloud Load Balancer

E.VPC Network Peering

AnswersB, D

Caches content at edge locations for faster delivery.

Why this answer

Cloud CDN (Option B) caches content at Google's globally distributed edge points of presence (PoPs), reducing latency by serving users from the nearest cache instead of the origin. The Global Cloud Load Balancer (Option D) provides a single anycast IP address that routes traffic to the closest healthy backend across multiple regions, maximizing availability through automatic failover and global traffic distribution.

Exam trap

Google Cloud often tests the misconception that Cloud Interconnect or VPC Peering are needed for multi-region performance, when in fact the Global Cloud Load Balancer and Cloud CDN are the correct services for minimizing latency and maximizing availability across regions.

MCQeasy

A company uses Cloud Armor to protect their HTTP Load Balancer. They want to block requests from a specific IP range during a DDoS attack. What is the most efficient way to implement this?

A.Create a new Cloud Armor security policy and attach it to the backend service.

B.Modify the load balancer's firewall rule to deny traffic from that IP range.

C.Use Cloud CDN to cache responses and block the IP at the edge.

D.Update the existing security policy by adding a deny rule for the IP range with priority 1000.

AnswerD

Adding a deny rule to the existing policy is immediate and efficient.

Why this answer

Option B is correct because updating the existing security policy by adding a deny rule is the quickest and most efficient way to block the IP range during an active attack. Option A is less efficient as it requires creating a new policy and reconfiguring the attachment. Option C is incorrect because firewall rules operate at the network layer and cannot block HTTP-level requests.

Option D is incorrect because Cloud CDN does not provide IP blocking capabilities.

A company is migrating to Google Cloud and needs to comply with the Health Insurance Portability and Accountability Act (HIPAA). They plan to use Cloud SQL for MySQL and Cloud Storage. Which TWO actions must they take to ensure HIPAA compliance?

Select 2 answers

A.Sign a Business Associate Agreement (BAA) with Google Cloud.

B.Disable automatic backups to prevent exposure of protected health information (PHI).

C.Enable encryption at rest for Cloud SQL and Cloud Storage.

D.Implement VPC Service Controls to create a perimeter around the projects.

E.Use customer-managed encryption keys (CMEK) for all services.

AnswersA, C

A BAA is required for any HIPAA-covered entity using Google Cloud services.

Why this answer

Option B and D are correct. HIPAA requires a Business Associate Agreement (BAA) with Google, and encryption at rest must be enabled. Cloud SQL and Cloud Storage both support encryption at rest.

Option A is wrong because disabling automatic backups is not a HIPAA requirement. Option C is wrong because VPC Service Controls are for data exfiltration prevention, not specifically required by HIPAA. Option E is wrong because HIPAA does not mandate a specific key management service; CMEK is optional.

A company has deployed a web application on Compute Engine instances in a managed instance group behind an internal HTTP(S) load balancer. The application needs to be accessible only from the corporate office, which has a static public IP range of 203.0.113.0/24. The load balancer is in us-central1. What is the most secure way to restrict access?

A.Create a VPC firewall rule that allows traffic from 203.0.113.0/24 to the load balancer's forwarding rule IP.

B.Assign a public IP to the internal load balancer and restrict access using Google Cloud Armor.

C.Configure a Cloud VPN tunnel between on-premises and VPC, then create a firewall rule allowing the corporate IP range to the internal load balancer's backend instances.

D.Use Google Cloud Armor with IP allowlisting on the internal load balancer.

AnswerC

This provides secure connectivity and allows fine-grained access control.

Why this answer

Option C is correct because an internal HTTP(S) load balancer has a private IP address that is only reachable from within the same VPC or via Cloud VPN / Cloud Interconnect. To allow access from a corporate office with a static public IP range, you must establish a Cloud VPN tunnel to extend the VPC network to the on-premises network, then create a firewall rule that permits traffic from the corporate IP range to the internal load balancer's backend instances. This ensures traffic traverses an encrypted tunnel and is subject to VPC firewall controls, providing the most secure and architecturally correct solution.

Exam trap

Google Cloud often tests the misconception that internal load balancers can be secured with Cloud Armor or that VPC firewall rules can filter traffic based on source public IPs when the destination is a private IP, but in reality, internal load balancers are only reachable from within the VPC or via hybrid connectivity like Cloud VPN.

How to eliminate wrong answers

Option A is wrong because an internal load balancer's forwarding rule IP is a private RFC 1918 address, not a public IP; VPC firewall rules cannot filter traffic destined to a private IP based on source public IPs because the traffic never reaches the load balancer from the internet. Option B is wrong because assigning a public IP to an internal load balancer is not supported; internal load balancers are designed to only have private IPs, and exposing them with a public IP would defeat the purpose of an internal load balancer. Option D is wrong because Google Cloud Armor cannot be directly attached to an internal HTTP(S) load balancer; Cloud Armor is only supported for external HTTP(S) load balancers, not internal ones.

Which two best practices for managing secrets in Secret Manager? (Choose two.)

Select 2 answers

A.Enable automatic replication to multiple regions for high availability.

B.Use the Secret Manager API to list all secrets for any user.

C.Set a short TTL for secret versions and delete them immediately.

D.Store secrets in multiple ConfigMaps for redundancy.

E.Use IAM conditions to restrict access based on resource tags.

AnswersA, E

Replication ensures availability if a region fails.

Why this answer

Option A is correct because Secret Manager supports automatic replication across regions, ensuring that secret data remains available even during a regional outage. This is a key best practice for high availability and disaster recovery, as it allows applications to read secrets from the nearest or alternate region without manual intervention.

Exam trap

Google Cloud often tests the misconception that ConfigMaps are suitable for secrets or that short TTLs and immediate deletion are safe practices, when in fact they violate operational stability and security best practices.

A healthcare organization stores Protected Health Information (PHI) in Cloud Storage. They need to de-identify data before sharing it with researchers. Which service should they use?

A.Cloud Key Management Service (KMS)

B.VPC Service Controls

C.Cloud IAM

D.Cloud Data Loss Prevention (DLP)

AnswerD

DLP can de-identify structured and unstructured data, including PHI.

Why this answer

Cloud Data Loss Prevention (DLP) is the correct service because it is specifically designed to inspect, classify, and de-identify sensitive data such as Protected Health Information (PHI). It uses built-in infoTypes (e.g., US_INDIVIDUAL_HEALTHCARE_NPI) and de-identification techniques like masking, tokenization, and redaction to transform PHI into a de-identified dataset before sharing with researchers, ensuring compliance with HIPAA.

Exam trap

Google Cloud often tests the distinction between data protection services (encryption, access control, perimeter security) and data de-identification, so the trap here is that candidates confuse Cloud KMS or IAM with DLP because they all relate to 'protecting' data, but only DLP actively transforms sensitive content to remove identifiers.

How to eliminate wrong answers

Option A is wrong because Cloud Key Management Service (KMS) is used for managing encryption keys, not for de-identifying data; it protects data at rest but does not remove or transform PHI. Option B is wrong because VPC Service Controls provide a security perimeter to prevent data exfiltration from VPC services, but they do not inspect or de-identify the content of data. Option C is wrong because Cloud IAM manages access control policies (who can access resources), but it does not perform data de-identification or content inspection.

A company uses Cloud SQL for PostgreSQL with CMEK. They need to ensure that the Cloud SQL instance can only be accessed by authorized compute resources that have the correct IAM permissions to decrypt the data. What additional configuration is required to enforce access control?

A.Enable mutual TLS for all connections to the Cloud SQL instance.

B.Set up a service account with Cloud KMS CryptoKey Encrypter/Decrypter and attach it to authorized VMs.

C.Use VPC Service Controls to restrict access to the Cloud SQL instance and the key.

D.Configure Cloud SQL to use Cloud Armor to whitelist IP addresses.

AnswerB

This ensures only specific VMs can decrypt, coupling compute access with key access.

Why this answer

Option B is correct because Cloud SQL with CMEK requires that any compute resource accessing the instance must have the Cloud KMS CryptoKey Encrypter/Decrypter IAM role on the key. By attaching a service account with this role to authorized VMs, you ensure that only those VMs can decrypt the data at rest, enforcing access control at the IAM level. This directly ties the decryption permission to the compute resource's identity, not just network-level access.

Exam trap

Google Cloud often tests the distinction between network-level access controls (like VPC Service Controls or Cloud Armor) and IAM-based key authorization, leading candidates to choose perimeter security options instead of the correct identity-based decryption permission.

How to eliminate wrong answers

Option A is wrong because mutual TLS (mTLS) authenticates the client and server at the transport layer but does not control decryption permissions for CMEK; it addresses connection security, not key access. Option C is wrong because VPC Service Controls restrict data exfiltration and network access to Google Cloud services, but they do not grant or enforce IAM permissions to decrypt the CMEK key; they are a perimeter security control, not a key authorization mechanism. Option D is wrong because Cloud Armor is a web application firewall that filters traffic based on IP addresses or HTTP headers, but it cannot enforce IAM-based decryption permissions; it operates at the network edge, not at the key management layer.

A company stores sensitive customer data in Cloud Storage. They want to ensure that data is encrypted at rest using customer-managed encryption keys (CMEK) and that access to the key is audited. Which approach should they use?

A.Use Google-managed encryption keys and enable Cloud Audit Logs for the bucket.

B.Use CMEK with key material stored in a Cloud Storage bucket.

C.Use customer-supplied encryption keys (CSEK) and store the keys in Secret Manager.

D.Use CMEK with a Cloud KMS key and enable Cloud Audit Logs for the key.

AnswerD

CMEK uses Cloud KMS, and audit logs track access to the key.

Why this answer

Option D is correct because it combines customer-managed encryption keys (CMEK) via Cloud KMS with Cloud Audit Logs enabled on the key itself. This ensures the data is encrypted at rest using a key that the customer controls and rotates, and all operations against that key (e.g., encrypt, decrypt, enable, disable) are logged for auditing. Cloud Audit Logs on the bucket alone would not capture key access events, which is required for full auditability.

Exam trap

Google Cloud often tests the distinction between CMEK and CSEK, and the trap here is that candidates confuse 'customer-managed' with 'customer-supplied' and overlook that CMEK requires Cloud KMS for key management and auditing, not just storing key material in Cloud Storage or Secret Manager.

How to eliminate wrong answers

Option A is wrong because Google-managed encryption keys do not allow customer control or rotation of the key material, and enabling Cloud Audit Logs only on the bucket does not audit access to the encryption key itself. Option B is wrong because storing CMEK key material in a Cloud Storage bucket violates the principle of keeping keys separate from the data they protect, and Cloud Storage does not provide the key management lifecycle or audit logging that Cloud KMS offers. Option C is wrong because customer-supplied encryption keys (CSEK) require the customer to supply the key on every API call, and storing the keys in Secret Manager does not provide the same level of key rotation, versioning, or centralized audit logging as Cloud KMS with CMEK.

Your organization has a VPC with several subnets and wants to enable Private Google Access for Compute Engine instances in a specific subnet to access Google APIs and services without external IP addresses. What must be configured?

A.Assign external IPs to the instances and create a firewall rule allowing egress to Google APIs.

B.Create a Cloud NAT gateway and enable Private Google Access on the subnet.

C.Enable Private Google Access on the subnet and ensure that instances have a default route (0.0.0.0/0) with next hop to the default internet gateway.

D.Enable Private Google Access on the subnet only.

AnswerC

Private Google Access works with the default route to the internet gateway; no NAT needed.

Why this answer

Option C is correct because Private Google Access requires two components: enabling it on the subnet and having a default route (0.0.0.0/0) pointing to the internet gateway. This route allows instances without external IPs to use the VPC's default internet gateway to reach Google APIs via the 199.36.153.4/30 address range, which is advertised by Google's private IP space. Without the default route, traffic from the subnet cannot reach the internet gateway, even with Private Google Access enabled.

Exam trap

Google Cloud often tests the misconception that Cloud NAT is required for Private Google Access, but the correct configuration relies solely on the default internet gateway and a default route, not NAT.

How to eliminate wrong answers

Option A is wrong because assigning external IPs defeats the purpose of Private Google Access, which is designed for instances without public IPs, and a firewall rule alone does not enable the necessary routing. Option B is wrong because Cloud NAT is used for outbound internet access to non-Google services, not for Private Google Access, which uses the default internet gateway and Google's private IP range. Option D is wrong because enabling Private Google Access on the subnet alone is insufficient; a default route (0.0.0.0/0) with next hop to the default internet gateway is required to direct traffic to Google APIs.

Refer to the exhibit. A security engineer runs the gcloud command to analyze IAM policy for a user in an organization. The output shows that the user has the 'compute.instances.create' permission via a role at the organization level. However, the user is unable to create Compute Engine instances in a specific project. What is the most likely cause?

A.The user does not have the 'compute.instances.create' permission at the project level.

B.The user has the permission but through a different role than expected.

C.An organization policy constraint is denying the creation of Compute Engine instances.

D.The user's role is not granted at the project level.

AnswerC

Organization policies can deny actions even if IAM allows them.

Why this answer

Option C is correct because organization policy constraints in Google Cloud can override IAM permissions at any level. Even if the user has the 'compute.instances.create' permission via an organization-level role, an organization policy constraint (e.g., constraints/compute.vmExternalIpAccess or constraints/compute.restrictCreateVM) can explicitly deny the creation of Compute Engine instances in a specific project. This is a common scenario where IAM allows the action, but organization policy blocks it.

Exam trap

Google Cloud often tests the distinction between IAM permissions and organization policy constraints, trapping candidates who assume that having the correct IAM permission at any level is sufficient to perform an action, without considering that organization policies can override IAM.

How to eliminate wrong answers

Option A is wrong because the user has the permission at the organization level, which is inherited by all projects in the organization, so the permission is effectively present at the project level. Option B is wrong because the role through which the permission is granted is irrelevant; IAM evaluates permissions based on the permission itself, not the role name. Option D is wrong because the role is granted at the organization level, and organization-level roles are inherited by all projects, so the role is effectively granted at the project level.

B.Enable automatic rotation on the key.

C.Create a new key version every 90 days manually.

D.Ensure the key is destroyed after rotation.

E.Use a Cloud Function to trigger rotation.

Users are reporting 502 Bad Gateway errors when accessing an application behind an external HTTPS Load Balancer. What is the most likely cause?

A.The backend instances are unhealthy or the SSL certificate is invalid

B.Cloud CDN is not enabled for the load balancer

C.The backend instances have reached maximum concurrent connections

D.The load balancer is configured as an internal load balancer

AnswerA

A 502 error indicates a communication failure between the load balancer and backend, often due to health check failures or SSL misconfiguration.

Why this answer

Option B is correct because 502 errors typically indicate that the load balancer cannot communicate with the backend, often due to unhealthy instances or SSL certificate issues. Option A is wrong because connection limits cause 503 or 429 errors, not 502. Option C is wrong because the load balancer type is correct for HTTPS.

A developer needs to create and manage Compute Engine instances in a project. They require the ability to start, stop, and view instances, but should not be able to delete or modify network configurations. Which predefined role should be assigned?

A.roles/compute.viewer

B.roles/iam.serviceAccountUser

C.roles/compute.admin

D.roles/compute.instanceAdmin.v1

AnswerD

Provides the required permissions: compute.instances.* except delete, and compute.instances.start/stop.

Why this answer

Option D is correct because the `roles/compute.instanceAdmin.v1` role grants permissions to start, stop, and view Compute Engine instances, but explicitly excludes permissions to delete instances or modify network configurations. This predefined role is designed for users who need operational control over instances without full administrative access.

Exam trap

Google Cloud often tests the distinction between `roles/compute.instanceAdmin.v1` and `roles/compute.admin`, where candidates mistakenly choose the admin role for operational tasks, overlooking the fact that admin includes destructive permissions like deletion and network modification.

How to eliminate wrong answers

Option A is wrong because `roles/compute.viewer` only provides read-only access to view Compute Engine resources, not the ability to start or stop instances. Option B is wrong because `roles/iam.serviceAccountUser` allows a user to impersonate a service account, but does not grant any permissions to manage Compute Engine instances. Option C is wrong because `roles/compute.admin` grants full administrative access to all Compute Engine resources, including the ability to delete instances and modify network configurations, which exceeds the required permissions.

C.Set an organization policy to disable public access to all Cloud Storage buckets.

D.Create a Cloud Security Command Center notification for public bucket findings and use a Cloud Function to automatically disable public access.

Automated response reduces recurrence risk.

Why this answer

Option B is correct because creating a security health analytics sink to Pub/Sub enables automated remediation. Option A is incorrect because deleting the bucket may lose data.

Refer to the exhibit. A security engineer reviews this IAM policy. Which compliance requirement does this policy help satisfy?

A.Key rotation schedule for encryption keys

B.Data residency by limiting access to European regions

C.Audit logging of data access

D.Encryption of data at rest

AnswerB

By restricting access to resources in europe-west, the policy supports data residency compliance.

Why this answer

The IAM policy includes a `Condition` block using `aws:RequestedRegion` to explicitly deny access to any AWS region outside of the specified European regions (eu-west-1, eu-central-1, etc.). This enforces data residency by ensuring that API calls that would create or modify resources are restricted to approved geographic boundaries, helping satisfy compliance requirements such as GDPR or local data sovereignty laws.

Exam trap

Google Cloud often tests the distinction between IAM policies that control access (like region restriction) versus resource-level configurations (like encryption or logging), leading candidates to confuse a condition-based access control policy with a data protection mechanism.

How to eliminate wrong answers

Option A is wrong because key rotation schedules are managed through AWS KMS key policies or automated rotation settings, not through IAM policies that control API access based on region. Option C is wrong because audit logging of data access is enabled by services like AWS CloudTrail or Amazon S3 server access logs, not by an IAM policy that restricts regional access. Option D is wrong because encryption of data at rest is enforced through encryption settings on the resource itself (e.g., S3 SSE, EBS encryption) or via KMS key policies, not by an IAM policy that limits the regions where API calls can be made.

C.Enforce multi-factor authentication (MFA) for all users accessing the Google Cloud Console.

D.Create custom IAM roles that grant only the minimum permissions required for each job function.

E.Implement VPC Service Controls to prevent data exfiltration.

AnswersA, C, D

Session timeouts are required for access control.

Why this answer

Option A is correct because FedRAMP Moderate requires session timeout policies to mitigate the risk of unauthorized access from unattended sessions. Google Cloud IAM session settings allow you to enforce a maximum session duration, and setting it to 15 minutes aligns with the FedRAMP requirement for automatic logout of inactive users. This directly addresses the access control family (AC-12) in the FedRAMP baseline.

A security engineer reviews the IAM policy for a Cloud Storage bucket as shown in the exhibit. Alice reports that she cannot upload objects to the bucket, while Bob can view objects. What is the most likely issue?

A.The bucket has ACLs that deny Alice upload access.

B.Alice has the objectViewer role but not the objectAdmin role.

C.Alice does not have the storage.buckets.getIamPolicy permission.

D.The objectAdmin role does not include the storage.objects.create permission.

AnswerA

If uniform bucket-level access is not enabled, ACLs can override IAM.

Why this answer

Option A is correct because Cloud Storage buckets can have both IAM policies and Access Control Lists (ACLs) applied. If the bucket's ACL explicitly denies Alice the `WRITER` or `OWNER` permission, she will be unable to upload objects even if her IAM policy grants broader roles. Bob can view objects because his IAM role (e.g., `roles/storage.objectViewer`) is not overridden by a conflicting ACL, or his ACL entry grants `READER` access.

Exam trap

Google Cloud often tests the misconception that IAM policies alone control all access to Cloud Storage, ignoring that ACLs can override or deny permissions, leading candidates to incorrectly blame missing roles or permissions rather than a conflicting ACL.

How to eliminate wrong answers

Option B is wrong because the `objectViewer` role only allows reading objects, not uploading; however, the question states Alice cannot upload, so the issue is not about missing `objectAdmin` but a specific denial. Option C is wrong because `storage.buckets.getIamPolicy` is used to view the bucket's IAM policy, not to upload objects; lacking this permission would not prevent uploading. Option D is wrong because the `objectAdmin` role (`roles/storage.objectAdmin`) does include `storage.objects.create`, which is required for uploading; this option misrepresents the role's permissions.

Select 2 answers

A.Set a key destruction policy to prevent accidental deletion of the key.

B.Use Cloud External Key Manager (EKM) to manage the key externally.

C.Create a Cloud KMS key ring and key with a rotation period of 30 days.

D.Use a Cloud HSM key with protection level HSM to meet key storage requirements.

E.Grant the Cloud Storage service account the Cloud KMS CryptoKey Encrypter/Decrypter role on the key.

AnswersC, E

The key must have a rotation schedule to meet the requirement.

Why this answer

Option C is correct because Cloud KMS allows you to set a rotation period on a key, and when you use a CMEK with Cloud Storage, the key is used to encrypt the data encryption keys (DEKs). Setting a rotation period of 30 days ensures that the key material is automatically rotated every 30 days, meeting the compliance requirement. Option E is correct because the Cloud Storage service account must be granted the Cloud KMS CryptoKey Encrypter/Decrypter role to be authorized to use the CMEK for encrypting and decrypting objects.

Exam trap

Google Cloud often tests the distinction between key rotation (a lifecycle policy) and key protection (HSM or destruction policies), so candidates mistakenly select options that address security or deletion prevention instead of the rotation requirement.

A multinational corporation is implementing a least-privilege access model for their CI/CD pipeline using Cloud Build, Artifact Registry, and GKE. The pipeline builds container images, pushes them to Artifact Registry, and deploys them to GKE clusters. The security team wants to ensure that the Cloud Build service account used by the pipeline has only the minimum necessary permissions. The service account currently has: roles/cloudbuild.builds.editor, roles/artifactregistry.writer, and roles/container.developer. After a successful build and push, the deployment step completes without errors, but the newly deployed pods on GKE immediately fail with ImagePullBackOff errors. The error message indicates: "Failed to pull image 'us-central1-docker.pkg.dev/my-project/my-repo/my-image:latest': rpc error: code = PermissionDenied desc = unauthenticated: Request had insufficient authentication scopes." The GKE cluster is a private cluster with Workload Identity enabled. The node pool uses a default Compute Engine service account with only the storage scope. What is the most likely missing permission or configuration that prevents the pods from pulling images?

A.The service account needs roles/artifactregistry.reader on the repository.

B.The service account needs roles/storage.objectViewer on the bucket where images are cached.

C.The service account needs roles/container.clusterAdmin on the cluster.

D.The service account needs roles/iam.serviceAccountUser on the GKE node service account.

AnswerD

Option B is correct; with Workload Identity, the pod's Kubernetes service account (typically the default) maps to the node service account. Granting the Cloud Build service account the serviceAccountUser role on the node service account allows impersonation for pulling images.

Why this answer

Option D is correct because the Cloud Build service account needs the `roles/iam.serviceAccountUser` permission on the GKE node's Compute Engine service account to impersonate it. With Workload Identity enabled, the GKE node's service account (not the Cloud Build service account) is what authenticates to Artifact Registry when pods pull images. Without this delegation, the Cloud Build service account cannot act on behalf of the node's service account, leading to the `PermissionDenied` error.

Exam trap

Google Cloud often tests the misconception that the Cloud Build service account itself needs Artifact Registry read permissions, when in reality the node's service account must have those permissions and the Cloud Build service account needs the `iam.serviceAccountUser` role to impersonate it.

How to eliminate wrong answers

Option A is wrong because the Cloud Build service account already has `roles/artifactregistry.writer`, which includes read permissions; the issue is not about the Cloud Build service account's permissions but about the node's service account lacking Artifact Registry read access. Option B is wrong because Artifact Registry does not use Cloud Storage buckets for image caching; images are stored directly in the registry, and the error is about authentication scopes, not storage permissions. Option C is wrong because `roles/container.clusterAdmin` grants cluster management permissions, not the ability to pull images from Artifact Registry; the error occurs at the pod level, not during deployment.

A small company has a single VPC with subnets in us-central1 (10.0.1.0/24) and us-west1 (10.0.2.0/24). They have a Compute Engine VM (web-server) in us-central1 that needs to connect to a Cloud SQL MySQL instance also in us-central1 using its private IP address 10.0.1.3. The Cloud SQL instance is configured with private IP only and is deployed in the same VPC. The web-server can successfully ping the Cloud SQL private IP (10.0.1.3). However, the application on the web-server fails to connect to the MySQL database with an authentication error. There are no custom firewall rules; only the default VPC firewall rules are in place. What is the most likely cause of the connection failure?

A.The default-allow-internal firewall rule does not allow TCP port 3306.

B.The web-server's service account lacks the Cloud SQL Client IAM role.

C.The Cloud SQL instance does not have the public IP address enabled.

D.The Cloud SQL instance is in a different region than the web-server.

AnswerB

This role is necessary to authenticate to Cloud SQL; without it, the application fails with a permission error.

Why this answer

The web-server can ping the Cloud SQL private IP (10.0.1.3), confirming network connectivity at Layer 3. The authentication error indicates the application is reaching the database but being denied access. Cloud SQL uses IAM for authentication when connecting via private IP; the web-server's service account must have the Cloud SQL Client IAM role to authenticate successfully.

Without this role, the connection is rejected even though the network path is open.

Exam trap

Google Cloud often tests the distinction between network connectivity (Layer 3 reachability) and application-layer authentication, leading candidates to incorrectly blame firewall rules or IP configuration when the real issue is missing IAM permissions for Cloud SQL private IP access.

How to eliminate wrong answers

Option A is wrong because the default-allow-internal firewall rule in GCP allows all TCP traffic (including port 3306) between instances in the same VPC, so it does not block MySQL connections. Option C is wrong because the Cloud SQL instance is configured with private IP only, which is sufficient for connectivity; enabling a public IP is not required for private access and would not cause an authentication error. Option D is wrong because both the web-server and the Cloud SQL instance are in us-central1, as stated in the scenario, so region mismatch is not the issue.

The backend consists of a managed instance group for the application tier and a Cloud Storage bucket for static assets. During peak traffic, some users receive HTTP 503 errors. The backend instances are healthy and the load balancer shows no connection errors. The company has already enabled Cloud CDN for the backend bucket. What should they do to resolve the 503 errors?

A.Increase the size of the instance group to handle more requests.

B.Enable Cloud CDN on the backend bucket to cache static content.

C.Increase the backend bucket's cache mode to force caching of dynamic content.

D.Adjust the load balancer's connection draining timeout.

AnswerA

Scaling up the instance group adds capacity to serve more requests, reducing 503 errors from resource exhaustion.

Why this answer

The 503 errors likely indicate that the instance group cannot handle the request volume. Increasing the size of the instance group provides more capacity. Option B is incorrect because CDN is already enabled for static content, and the 503 is likely for dynamic content.

Option C is incorrect because connection draining affects instance removal, not capacity. Option D is incorrect because forcing caching of dynamic content may serve stale data or not be allowed.

A new employee needs to be able to create and manage Compute Engine instances. Which role should be granted at the project level?

A.roles/compute.instanceAdmin

B.roles/compute.admin

C.roles/compute.networkAdmin

D.roles/compute.viewer

AnswerA

This role includes the necessary permissions to create and manage instances.

Why this answer

The roles/compute.instanceAdmin role grants permissions to create, modify, and delete Compute Engine instances, including starting, stopping, and managing disks and snapshots, but does not allow changing project-wide network configurations or granting IAM policies. This is the least-privilege role that meets the requirement to 'create and manage Compute Engine instances' at the project level.

Exam trap

The trap here is that candidates often confuse 'admin' with 'instanceAdmin', assuming the broader role is required, but the PCSE exam emphasizes granting the minimal set of permissions needed to perform a specific job function.

How to eliminate wrong answers

Option B (roles/compute.admin) is wrong because it grants full administrative access to all Compute Engine resources, including network and security settings, which exceeds the stated need and violates the principle of least privilege. Option C (roles/compute.networkAdmin) is wrong because it only allows management of networking resources (firewalls, routes, VPNs) and does not grant permissions to create or manage instances. Option D (roles/compute.viewer) is wrong because it provides read-only access to Compute Engine resources, with no ability to create, modify, or delete instances.

A DevOps team wants to grant a contractor temporary access to a specific Cloud Storage bucket for 30 days. The contractor has a Google account (example@gmail.com). The bucket contains sensitive data, and the access should be as restrictive as possible. What is the recommended way to grant this access?

A.Create a bucket ACL granting the contractor READ access.

B.Add the contractor's email to the project-level IAM policy with the 'Storage Object Viewer' role.

C.Add the contractor's email to the bucket-level IAM policy with the 'Storage Object Viewer' role.

D.Generate a signed URL for the contractor to access the bucket objects.

AnswerC

Bucket-level IAM is granular and can be removed after 30 days.

Why this answer

Option C is correct because bucket-level IAM policies allow you to grant granular, time-bound access to a specific bucket without affecting other resources in the project. By adding the contractor's email (example@gmail.com) to the bucket-level IAM policy with the 'Storage Object Viewer' role, you restrict access to only that bucket and only to read objects, which is the most restrictive approach for a 30-day temporary access requirement.

Exam trap

Google Cloud often tests the distinction between project-level and resource-level IAM policies, and the trap here is that candidates choose project-level IAM (Option B) thinking it's simpler, but they overlook that it grants access to all buckets in the project, violating the principle of least privilege.

How to eliminate wrong answers

Option A is wrong because bucket ACLs are legacy and do not support IAM conditions for time-bound access; they also lack the granularity of IAM roles and are not recommended for new configurations. Option B is wrong because adding the contractor to the project-level IAM policy grants read access to all storage buckets in the project, which violates the 'as restrictive as possible' requirement and exposes other sensitive data. Option D is wrong because signed URLs provide temporary access to specific objects, not the entire bucket, and managing them for all objects over 30 days is impractical and insecure for ongoing bucket-level access.

Which TWO of the following are valid Google Cloud firewall rule components? (Choose TWO.)

Select 2 answers

A.Priority

B.Protocol signature

C.Target service accounts

D.Next hop

E.Network tier

AnswersA, C

Priority determines the order in which rules are evaluated.

Why this answer

A is correct because firewall rules in Google Cloud require a priority value (0–65535) to determine evaluation order. Lower numbers are evaluated first, and the first matching rule is applied. This is a mandatory component of every firewall rule.

Exam trap

Google Cloud often tests the distinction between firewall rule components and routing/network tier components, so candidates mistakenly select 'Next hop' or 'Network tier' because they are familiar networking terms, but they are not part of a firewall rule definition.

A financial institution uses Cloud HSM to protect cryptographic keys used for signing sensitive transactions. They want to ensure that keys are never exportable and that key usage is logged. Which key type should they create in Cloud HSM?

A.Purpose: ASYMMETRIC_SIGN with algorithm: RSA_SIGN_PKCS1_2048_SHA256

B.Purpose: SYMMETRIC_ENCRYPT_DECRYPT with algorithm: GOOGLE_SYMMETRIC_ENCRYPTION

C.Purpose: ASYMMETRIC_DECRYPT with algorithm: RSA_DECRYPT_OAEP_2048_SHA256

D.Purpose: MAC with algorithm: HMAC_SHA256

AnswerA

This key type is designed for signing and uses Cloud HSM which provides non-exportable keys.

Why this answer

Option A is correct because Cloud HSM supports ASYMMETRIC_SIGN key purpose with RSA_SIGN_PKCS1_2048_SHA256, which creates a non-exportable key pair used for signing. Cloud HSM ensures the private key never leaves the HSM boundary, and all key usage is automatically logged via Cloud Audit Logs, meeting the requirements for non-exportability and logging.

Exam trap

Google Cloud often tests the distinction between key purposes: candidates confuse ASYMMETRIC_DECRYPT (used for decrypting ciphertext) with signing, but signing requires the private key to produce a signature, not to decrypt data.

How to eliminate wrong answers

Option B is wrong because SYMMETRIC_ENCRYPT_DECRYPT keys are used for encryption/decryption, not signing, and symmetric keys do not provide the non-repudiation needed for signing sensitive transactions. Option C is wrong because ASYMMETRIC_DECRYPT keys are designed for decryption operations (e.g., RSA-OAEP), not for creating digital signatures; signing requires the private key to generate a signature, not to decrypt. Option D is wrong because MAC (Message Authentication Code) keys, such as HMAC_SHA256, are symmetric and used for integrity and authentication, not for asymmetric signing; they do not provide non-repudiation and are exportable by design in Cloud HSM.

A company is deploying a microservices architecture on Google Kubernetes Engine (GKE). They need to securely store and access database credentials, API keys, and other secrets. They want to avoid storing secrets in plaintext in the container image or Kubernetes manifests. Which solution should they use?

A.Encrypt secrets with Cloud KMS and store them in a ConfigMap.

B.Store secrets in a ConfigMap and mount as environment variables.

C.Use Secret Manager and mount secrets as volumes using the Secret Manager CSI driver.

D.Use Kubernetes native Secrets, committing them to a private repository.

AnswerC

This provides secure, audited access without storing secrets in the cluster.

Why this answer

Option C is correct because Secret Manager provides a centralized, secure, and auditable way to store secrets, and the Secret Manager CSI driver allows pods to mount these secrets as volumes without exposing them in the container image or Kubernetes manifests. This approach ensures secrets are never stored in plaintext on disk or in etcd, and it integrates with GKE's workload identity for fine-grained access control.

Exam trap

The trap here is that candidates often confuse Kubernetes native Secrets (which are only base64-encoded, not encrypted) with a secure solution, or they assume ConfigMaps can be used for secrets if encrypted, missing the fact that ConfigMaps are not designed for sensitive data and are stored in plaintext in etcd.

How to eliminate wrong answers

Option A is wrong because Cloud KMS is a key management service for encryption keys, not a secret store; storing encrypted secrets in a ConfigMap still leaves the secrets in etcd and Kubernetes API, and ConfigMaps are not designed for sensitive data. Option B is wrong because ConfigMaps store data in plaintext in etcd and can be easily read by anyone with access to the Kubernetes API, violating the requirement to avoid plaintext storage. Option D is wrong because committing Kubernetes native Secrets to a private repository still stores them in plaintext in the repository and in etcd, and native Secrets are only base64-encoded, not encrypted by default, which is not a secure practice.

A security engineer runs the command in the exhibit. The command fails with an error: 'Permission denied: cryptoKeyVersions.encrypt'. What is the most likely cause?

A.The key ring 'my-keyring' does not exist.

B.The user does not have the cloudkms.cryptoKeyVersions.encrypt permission on the key.

C.The key ring location is incorrect.

D.The user does not have the cloudkms.cryptoKeyVersions.decrypt permission.

AnswerB

The error indicates missing encrypt permission.

Why this answer

The error message 'Permission denied: cryptoKeyVersions.encrypt' explicitly indicates that the user lacks the cloudkms.cryptoKeyVersions.encrypt permission on the specific key version. In Google Cloud KMS, encrypt operations require the cloudkms.cryptoKeyVersions.encrypt permission (or a broader role like roles/cloudkms.cryptoKeyEncrypter) on the key resource. The command itself is syntactically correct, so the failure is due to insufficient IAM permissions, not resource existence or location.

Exam trap

Google Cloud often tests the distinction between resource existence errors (e.g., 'Not found') and permission errors (e.g., 'Permission denied'), so candidates must read the exact error message to avoid confusing missing resources with insufficient IAM permissions.

How to eliminate wrong answers

Option A is wrong because if the key ring 'my-keyring' did not exist, the error would be 'Not found' or 'Key ring not found', not a permission denied error. Option C is wrong because an incorrect location would produce a 'Not found' or 'Invalid location' error, not a permission denied error. Option D is wrong because the error specifically mentions 'encrypt', not 'decrypt'; lacking the decrypt permission would not cause an encrypt operation to fail with this error message.

An organization uses Assured Workloads for Google Cloud to meet FedRAMP compliance. They have enabled Access Transparency logs. During an audit, they need to provide evidence that Google personnel access was logged and reviewed. What is the primary benefit of using Access Transparency?

A.It provides logs detailing the actions of Google personnel when accessing customer data.

B.It blocks all Google personnel access to customer data.

C.It encrypts data with customer-managed keys.

D.It prevents data from being moved outside the organization's VPC.

AnswerA

Access Transparency logs record Google staff access events.

Why this answer

Option D is correct because Access Transparency logs provide near-real-time logs of Google administrators' access to customer data. Option A is wrong because Access Transparency does not block access; it logs it. Option B is wrong because encryption is separate.

Option C is wrong because VPC Service Controls, not Access Transparency, restrict data movement.

An organization uses Cloud DLP to scan a Cloud SQL database for PII. They want to automatically pseudonymize email addresses found in a specific column using a deterministic encryption that can be reversed for authorized users. The key must be stored in Cloud KMS. Which DLP transformation should they configure?

A.CryptoHashConfig with a cryptographic key from Cloud KMS.

B.CryptoDeterministicConfig with a key from Cloud KMS.

C.CryptoReplaceFfxFpeConfig using a key from Cloud KMS.

D.ReplaceWithInfoTypeConfig with a cryptographic key.

AnswerB

This provides deterministic, reversible encryption suitable for pseudonymization.

Why this answer

Option B is correct because CryptoDeterministicConfig performs deterministic encryption (same plaintext always produces the same ciphertext) using a key from Cloud KMS, which allows pseudonymization that can be reversed by authorized users. This matches the requirement for a reversible, deterministic transformation on email addresses in a Cloud SQL column.

Exam trap

Google Cloud often tests the distinction between deterministic encryption (reversible, same output for same input) and hashing (one-way), leading candidates to mistakenly choose CryptoHashConfig when they need reversibility.

How to eliminate wrong answers

Option A is wrong because CryptoHashConfig uses a cryptographic hash function (e.g., SHA-256) which is one-way and cannot be reversed, so it does not meet the requirement for reversible pseudonymization. Option C is wrong because CryptoReplaceFfxFpeConfig uses Format-Preserving Encryption (FFX) which preserves the format of the data (e.g., email structure) but is not specifically designed for deterministic encryption with Cloud KMS key management in this context; it is more suited for preserving format while encrypting, not for simple deterministic reversal. Option D is wrong because ReplaceWithInfoTypeConfig replaces the entire value with the info type name (e.g., 'EMAIL_ADDRESS') and does not use a cryptographic key or provide any encryption or reversibility.

Refer to the exhibit. A compliance auditor reviews the key configuration and finds a potential issue. What is the most likely compliance impact?

A.The key is disabled and cannot encrypt data

B.The key was created too recently

C.The key lacks automatic rotation, which may violate compliance requirements

D.The key is not used for the correct purpose

AnswerC

Many compliance standards (e.g., PCI DSS) require periodic key rotation; a null rotation period means no rotation is scheduled.

Why this answer

Option C is correct because many compliance frameworks (e.g., PCI DSS, SOC 2, NIST SP 800-57) require cryptographic keys to be rotated periodically to limit the amount of data encrypted under a single key and reduce the impact of key compromise. In Cisco's key configuration, if automatic rotation is not enabled or configured, the key remains static, which can violate these compliance mandates. The auditor identifies the lack of automatic rotation as a potential non-compliance issue, even if the key is otherwise valid and functional.

Exam trap

Google Cloud often tests the distinction between a key being 'functional' versus 'compliant' — candidates may assume that because a key works and is not expired, it is compliant, but the trap is that compliance frameworks require proactive rotation policies, not just key validity.

How to eliminate wrong answers

Option A is wrong because a key being disabled would be a separate administrative action or state; the exhibit does not show the key as disabled, and a disabled key would not be available for encryption at all, which is not the issue flagged by the auditor. Option B is wrong because the age of the key alone does not create a compliance impact unless a specific maximum key lifetime is defined by policy; the auditor's concern is about rotation, not recency. Option D is wrong because the key purpose (e.g., encryption, signing) is typically defined in the key's attributes or usage policy, and the exhibit does not indicate that the key is being used for an incorrect purpose; the issue is the lack of rotation, not misuse.

A.Use Cloud VPN with SSL VPN.

B.Use Cloud VPN with IPsec IKEv2.

C.Use Cloud NAT for outbound traffic.

D.Use Cloud VPN with IPsec IKEv1.

AnswersB, D

Cloud VPN supports IPsec with IKEv2.

Why this answer

Cloud VPN supports both IPsec IKEv1 and IKEv2 as valid protocols for establishing secure tunnels between on-premises networks and Google Cloud. IKEv2 offers improved stability and mobility support, but both are explicitly supported by Google Cloud VPN for protecting data in transit.

Exam trap

Google Cloud often tests the distinction between Cloud VPN (which uses IPsec with IKEv1 or IKEv2) and other connectivity options like Cloud Interconnect or SSL VPN, leading candidates to mistakenly select SSL VPN or MACsec as valid Cloud VPN methods.

A financial services company must ensure that its Google Cloud environment complies with PCI DSS. The security team needs to implement controls to protect cardholder data. Which TWO measures should they implement? (Choose TWO.)

Select 2 answers

A.Enable Data Access audit logs for all Cloud Storage buckets.

B.Use Security Command Center to detect misconfigurations.

C.Configure VPC Service Controls to restrict data movement from managed services.

D.Enable Shielded VMs on all Compute Engine instances.

E.Use Customer-Managed Encryption Keys (CMEK) to encrypt data at rest.

AnswersC, E

VPC Service Controls help prevent unauthorized data exfiltration, a PCI DSS requirement.

Why this answer

C is correct because VPC Service Controls create a security perimeter around Google Cloud managed services, preventing data exfiltration by restricting data movement from within the perimeter to unauthorized external networks. This is critical for PCI DSS compliance as it helps protect cardholder data from unauthorized access or transfer. E is correct because Customer-Managed Encryption Keys (CMEK) allow the organization to control and manage the encryption keys used to protect data at rest, meeting PCI DSS requirement 3.4 for rendering cardholder data unreadable.

Exam trap

Google Cloud often tests the distinction between detective controls (like audit logs and Security Command Center) and preventive controls (like VPC Service Controls and CMEK), leading candidates to mistakenly select logging or detection options as direct compliance measures.

To comply with regulatory requirements, a company needs to prevent service account keys from being created for all projects. What should they use?

A.VPC Service Controls

B.Organization policy with a constraint

C.Security Command Center

D.IAM conditions

AnswerB

The Organization policy `iam.disableServiceAccountKeyCreation` can be applied at the organization level to prevent key creation.

Why this answer

Organization policies with constraints allow you to enforce restrictions across all projects in an organization. The `constraints/iam.disableServiceAccountKeyCreation` constraint specifically prevents the creation of service account keys, ensuring compliance with regulatory requirements that prohibit long-lived keys. This is a native Google Cloud IAM feature that applies at the organization, folder, or project level.

Exam trap

Google Cloud often tests the distinction between preventive controls (organization policy constraints) and detective/monitoring tools (Security Command Center), leading candidates to mistakenly choose Security Command Center because they think it can block actions, when in fact it only detects and alerts.

How to eliminate wrong answers

Option A is wrong because VPC Service Controls are used to define security perimeters around Google Cloud resources to mitigate data exfiltration risks, not to manage IAM policies or service account key creation. Option C is wrong because Security Command Center is a security and risk management platform that provides threat detection and vulnerability findings, but it does not enforce preventive policies like disabling key creation. Option D is wrong because IAM conditions allow you to define conditional, attribute-based access to resources (e.g., based on time, IP address, or resource tags), but they cannot prevent the creation of service account keys themselves.

A company is using Cloud SQL for MySQL in production. They notice that during peak hours, query latency increases significantly. The database is running on a db-n1-standard-2 instance with 100GB SSD. The CPU utilization spikes to 95% during peaks. The application uses connection pooling. Which action should the company take to improve performance while minimizing cost?

A.Increase the storage to 200GB to improve IOPS.

B.Add a read replica and redirect read queries to it.

C.Enable Cloud SQL Proxy to cache connections.

D.Increase the number of CPUs by switching to a db-n1-highcpu-2 instance.

AnswerB

Read replicas handle SELECT queries, reducing the primary instance's load and lowering latency for read-heavy workloads.

Why this answer

Adding a read replica offloads read queries from the primary instance, reducing CPU load and latency. Option A is incorrect because switching to a highcpu type does not increase CPU count; it rebalances memory. Option B is incorrect because Cloud SQL Proxy provides secure connections, not performance improvement.

Option D is incorrect because increasing storage primarily increases IOPS and disk throughput, but CPU is the bottleneck.

A company needs to respond to a GDPR data subject deletion request for a user's data stored across BigQuery and Cloud Storage. The data must be completely erased upon request. What is the most effective approach to ensure compliance?

A.Use Cloud DLP to identify the user's data across services, delete the data using API calls, and verify deletion with Cloud Audit Logs

B.Set up BigQuery time-based table expiration and Cloud Storage lifecycle policies with a 1-day deletion rule

C.Use Cloud Identity-Aware Proxy to block the user's access and mark the data as deleted

D.Enable Access Transparency logs and request Google to delete the data on their behalf

AnswerA

Cloud DLP discovers data locations, deletion APIs remove data, and audit logs confirm deletion, meeting GDPR requirements.

Why this answer

Option A is correct because Cloud DLP can be used to inspect and classify the user's data across BigQuery and Cloud Storage, then you can programmatically delete the identified data via API calls. Cloud Audit Logs provide a verifiable record that the deletion was performed, which is essential for demonstrating compliance with GDPR's right to erasure.

Exam trap

Google Cloud often tests the misconception that access control mechanisms (like IAP) or automated lifecycle policies can substitute for actual data deletion, but GDPR requires complete erasure of the specific data subject's information, not just blocking access or delayed removal.

How to eliminate wrong answers

Option B is wrong because time-based table expiration and lifecycle policies are automated deletion mechanisms that cannot target a specific user's data on demand; they delete entire tables or objects based on age, not in response to an individual deletion request. Option C is wrong because Cloud Identity-Aware Proxy controls access but does not delete data; marking data as deleted without actual erasure fails GDPR's requirement for complete removal. Option D is wrong because Access Transparency logs only provide visibility into Google's access to your data, and requesting Google to delete data on your behalf is not a supported mechanism for customer-managed data in BigQuery or Cloud Storage.

C.Export Admin Activity audit logs to a centralized project's BigQuery dataset.

D.Use Cloud Asset Inventory with IAM policy change feed.

AnswerC

Admin Activity logs include firewall rule changes; BigQuery enables efficient querying.

Why this answer

Option C is correct. Exporting Admin Activity audit logs to a centralized BigQuery dataset allows querying all firewall rule changes across projects. Option A is incorrect because VPC Flow Logs capture network traffic, not rule changes.

Option B is incorrect because Cloud Asset Inventory can track assets but not real-time changes efficiently. Option D is less efficient than a single export to BigQuery.

Your organization uses Shared VPC with a host project and several service projects. You need to ensure that all egress traffic from Compute Engine instances in a service project is routed through a centralized Cloud NAT in the host project. What is the required configuration?

A.Create a firewall rule in the host project that denies all egress traffic except to the Cloud NAT IP

B.Set the instances to use a custom route with next-hop as the Cloud NAT IP address

C.Configure a Cloud NAT on the Cloud Router in the host project for the subnet that is shared with the service project

D.Configure a Cloud NAT in each service project and associate it with the subnet that the instances use

AnswerC

Correct: In Shared VPC, the host project owns the subnets. Cloud NAT on the host project's router for those subnets will handle egress for all instances in those subnets, including those from service projects.

Why this answer

Option C is correct because a Cloud NAT configured on the Cloud Router in the host project for the shared subnet allows all Compute Engine instances in service projects attached to that subnet to use the host project's NAT IP for outbound traffic. This is the only way to centralize egress traffic through the host project's Cloud NAT while respecting Shared VPC architecture, as the NAT is tied to the subnet and Cloud Router in the host project.

Exam trap

Google Cloud often tests the misconception that a Cloud NAT must be configured in the same project as the instances, but in Shared VPC, the NAT is configured in the host project for the shared subnet, and service project instances automatically use it without any additional configuration.

How to eliminate wrong answers

Option A is wrong because firewall rules in the host project cannot selectively deny egress traffic for instances in a service project; firewall rules are applied per VPC network, not per project, and a deny-all-egress rule would block all outbound traffic, including legitimate responses, and does not route traffic through Cloud NAT. Option B is wrong because a custom route with next-hop as the Cloud NAT IP address is invalid; Cloud NAT is not a routable next-hop IP — it is a translation function on the Cloud Router, and instances must use the default route (0.0.0.0/0) to reach the internet via the NAT gateway. Option D is wrong because configuring a Cloud NAT in each service project would create separate NAT gateways, defeating the requirement for centralized egress through the host project's Cloud NAT.

A.Cloud Monitoring

B.Cloud Audit Logs

AnswerD

Log sinks can aggregate logs from multiple projects to a centralized destination.

Why this answer

Option C is correct because Cloud Logging log sinks can be configured to route logs from multiple projects to a common destination like a Cloud Storage bucket or BigQuery dataset in a separate project.

A company wants to protect its HTTP(S) Load Balancer from common web attacks like SQL injection and cross-site scripting. Which Google Cloud service should they use?

A.Identity-Aware Proxy (IAP)

B.Cloud Armor

C.VPC Service Controls

D.Cloud CDN

AnswerB

Cloud Armor offers WAF rules to block common web attacks.

Why this answer

Cloud Armor is the correct service because it provides web application firewall (WAF) capabilities that can inspect HTTP(S) traffic and filter out common web attacks such as SQL injection and cross-site scripting (XSS). It integrates directly with HTTP(S) Load Balancers to enforce security policies at the edge, blocking malicious requests before they reach backend instances.

Exam trap

The trap here is that candidates may confuse Cloud Armor with IAP because both involve security at the load balancer, but IAP handles authentication and authorization, not web application attack filtering.

How to eliminate wrong answers

Option A is wrong because Identity-Aware Proxy (IAP) is used for identity-based access control and authentication, not for inspecting HTTP payloads or blocking web application attacks like SQL injection or XSS. Option C is wrong because VPC Service Controls are designed to prevent data exfiltration by controlling access to Google Cloud APIs and services using perimeters, not for filtering application-layer traffic at the load balancer. Option D is wrong because Cloud CDN is a content delivery network that caches static and dynamic content to improve latency and reduce load, and it does not include a WAF or any capability to inspect or block malicious HTTP requests.

A security engineer runs the above query in BigQuery and finds a column containing Social Security Numbers (SSNs). They must ensure that all SSNs in the dataset are automatically encrypted at rest using customer-managed keys (CMEK) and also that future queries do not expose SSNs to users without decryption access. Which approach should they take?

A.Use BigQuery with CMEK on the dataset and create a separate table with encrypted columns.

B.Use Cloud DLP to de-identify the data in the table and then restrict access to the de-identified column.

C.Use Cloud KMS to encrypt the column values and store the encrypted data in BigQuery.

D.Enable CMEK on the dataset, create an authorized view that excludes the sensitive column, and grant view access to users.

AnswerD

CMEK secures data at rest, and authorized views limit exposure.

Why this answer

Option D is correct because enabling CMEK on the dataset ensures all data, including SSNs, is encrypted at rest with customer-managed keys. Creating an authorized view that excludes the sensitive column and granting view access to users prevents exposure of SSNs in query results while still allowing access to non-sensitive data. This approach meets both the encryption and access control requirements without requiring manual encryption or de-identification.

Exam trap

Google Cloud often tests the misconception that manual encryption (e.g., Cloud KMS or DLP) is required for column-level protection, when in fact BigQuery's native CMEK combined with authorized views provides automatic encryption at rest and access control without custom encryption logic.

How to eliminate wrong answers

Option A is wrong because creating a separate table with encrypted columns does not automatically encrypt existing SSNs at rest; CMEK on the dataset encrypts all data at rest, but the separate table approach adds complexity and does not prevent future queries from exposing SSNs unless access is restricted. Option B is wrong because Cloud DLP de-identifies data (e.g., masking or tokenization) but does not encrypt at rest with CMEK; it also does not prevent users with direct table access from querying the original SSNs if the de-identified column is separate. Option C is wrong because using Cloud KMS to encrypt column values and storing encrypted data in BigQuery requires manual encryption/decryption logic in queries, which is error-prone and does not leverage BigQuery's native CMEK for automatic encryption at rest; it also fails to prevent exposure if users have access to the raw encrypted data.

Refer to the exhibit. Based on the exhibit, the corporate security policy requires that all Cloud KMS symmetric keys have automatic rotation enabled. Which statement is true?

A.Both keys are compliant.

B.Neither key is compliant.

C.Only the encryption-key is compliant.

D.Only the decryption-key is compliant.

AnswerC

Encryption-key has a rotation period; decryption-key does not.

Why this answer

The corporate security policy requires automatic rotation for all Cloud KMS symmetric keys. In the exhibit, the 'encryption-key' has automatic rotation enabled (as indicated by the rotation period being set), while the 'decryption-key' does not have automatic rotation enabled (rotation period is not set or is disabled). Therefore, only the encryption-key is compliant with the policy.

Exam trap

Google Cloud often tests the distinction between keys that have rotation enabled versus those that are simply created with a rotation period set to a non-zero value, tricking candidates into assuming all keys in a key ring are automatically rotated.

How to eliminate wrong answers

Option A is wrong because both keys are not compliant; the decryption-key lacks automatic rotation. Option B is wrong because the encryption-key does have automatic rotation enabled, so it is compliant. Option D is wrong because the decryption-key does not have automatic rotation enabled, making it non-compliant, not the only compliant key.

A.Configure VPC Service Controls to restrict access to the Cloud SQL instance.

B.Use Cloud DLP to de-identify the data before storing it in Cloud SQL.

C.Enable Data Access audit logs for the Cloud SQL instance and Cloud KMS key.

D.Store the CMEK keys in Cloud HSM to meet FIPS 140-2 Level 3 requirements.

AnswerC

Data Access audit logs record all accesses to data and keys, satisfying HIPAA audit trail requirements.

Why this answer

Option C is correct because HIPAA audit requirements mandate that access to protected health information (PHI) and the keys protecting it must be logged. Enabling Data Access audit logs on both the Cloud SQL instance and the Cloud KMS key captures read, write, and administrative operations, providing the necessary audit trail for compliance. Without these logs, the organization cannot demonstrate who accessed the data or the encryption keys, which is a core HIPAA requirement.

Exam trap

Google Cloud often tests the distinction between security controls that prevent access (like VPC Service Controls or HSM) and controls that provide auditability (like Data Access audit logs), leading candidates to pick a security measure that does not fulfill the specific audit requirement.

How to eliminate wrong answers

Option A is wrong because VPC Service Controls restrict data exfiltration and access boundaries but do not generate the detailed audit logs required by HIPAA for tracking access to PHI and encryption keys. Option B is wrong because Cloud DLP de-identifies data before storage, which can reduce compliance scope but does not address the audit logging requirement for key management and data access. Option D is wrong because storing CMEK keys in Cloud HSM meets FIPS 140-2 Level 3 for key security but does not provide the access logging needed to satisfy HIPAA audit requirements.

A company must ensure that all data stored in Google Cloud remains within specific geographic regions to meet data residency regulations. Which TWO methods enforce data location restrictions? (Choose TWO.)

Select 2 answers

A.VPC Service Controls

B.Cloud Data Loss Prevention scan

C.Organization Policy constraints (constraints/gcp.resourceLocations)

D.Cloud Storage bucket custom locations (e.g., US, EU)

E.Cloud Interconnect

AnswersC, D

This policy limits resource creation to specified locations, enforcing data residency.

Why this answer

Option C is correct because Organization Policy constraints, specifically `constraints/gcp.resourceLocations`, allow administrators to define a list of allowed geographic locations (e.g., `in:us-central1` or `in:europe-west1`) where Google Cloud resources can be created. This policy is enforced at the project, folder, or organization level, preventing resource creation outside the permitted regions, which directly addresses data residency requirements.

Exam trap

Google Cloud often tests the distinction between data location enforcement (Organization Policy constraints) and data access control (VPC Service Controls), causing candidates to mistakenly choose VPC Service Controls for geographic restrictions.

A company uses Cloud Armor to protect an external HTTPS load balancer. They want to block requests from a specific IP address range 198.51.100.0/24, but allow all other traffic. After creating a deny rule with the source IP condition, they notice that requests from that range are still reaching the backend. What is the most likely cause?

A.Another rule with a lower priority number that allows all traffic is overriding the deny rule.

B.The rule action is set to 'allow' instead of 'deny'.

C.Cloud Armor cannot block traffic based on source IP; it only supports geographic and header-based conditions.

D.The rule uses the wrong match syntax, such as 'sourceIpRange' instead of 'inIpRange'.

AnswerA

Rules are evaluated in priority order; lower number wins. A default allow rule with priority 1000 might override a deny rule with higher priority.

Why this answer

In Cloud Armor, rules are evaluated in order of priority, where lower priority numbers indicate higher precedence. If a rule with a lower priority number (e.g., 1000) allows all traffic, it will be evaluated before a deny rule with a higher priority number (e.g., 2000), causing the deny rule to be overridden. This is the most likely reason the specific IP range is still reaching the backend despite the deny rule being created.

Exam trap

Google Cloud often tests the concept that priority numbers in Cloud Armor are evaluated from lowest to highest, and candidates mistakenly think a deny rule with a higher priority number will take precedence over an allow rule with a lower priority number.

How to eliminate wrong answers

Option B is wrong because if the rule action were set to 'allow' instead of 'deny', it would explicitly permit the traffic, not block it, but the question states the rule was created to deny, so this is a misconfiguration that would be obvious and not the most likely subtle cause. Option C is wrong because Cloud Armor fully supports source IP-based blocking using conditions like 'inIpRange' or source IP ranges in security policies, not just geographic or header-based conditions. Option D is wrong because Cloud Armor uses the 'sourceIpRange' syntax correctly for IP-based conditions; 'inIpRange' is not a valid match syntax in Cloud Armor rules, so this would cause a syntax error rather than silently allowing traffic.

MCQeasy

Your organization has a multi-project environment with centralized logging in a dedicated project (logging-project). All VPC Service Controls perimeters are configured correctly. The security team needs to ensure that all audit logs from all projects are retained for 5 years and cannot be deleted or modified by any project administrator. They also want to restrict access to the logs to only the security team members (who have the 'Security Reviewer' role at the organization level). Currently, each project has its own log sink that exports to a BigQuery dataset in logging-project. The security team notices that some project administrators have inadvertently deleted logs from their project's BigQuery dataset. You need to recommend a solution that prevents log deletion and enforces the retention policy. What should you do?

A.Configure the log sinks to export logs to a Cloud Storage bucket with a lifecycle rule that deletes objects after 5 years. Set the bucket's IAM policy to deny the storage.objects.delete permission to all users except the security team.

B.Create a new BigQuery dataset in logging-project with a table expiration of 5 years and configure the log sinks to export to this dataset. Grant the security team the BigQuery Data Viewer role and revoke all other users' access to the dataset.

C.Create a new organization-level log sink that exports logs to a BigQuery dataset in logging-project. Grant the security team the BigQuery Data Owner role on the dataset and remove all other project administrators from the dataset's permissions.

D.Configure the _Required and _Default log buckets in each project to route logs to a Cloud Storage bucket in logging-project using log sinks. Enable Object Hold and set a retention policy of 5 years on the bucket. Grant the security team the Storage Object Admin role on the bucket.

AnswerD

Correct: Cloud Storage retention policies and Object Hold prevent deletion or modification of objects during the retention period. This centralizes logs and enforces retention.

Why this answer

Option D is correct because it uses a Cloud Storage bucket with a retention policy and Object Hold to prevent deletion or modification of logs for 5 years. The retention policy enforces a minimum retention period, and Object Hold prevents object deletion even by project administrators. Log sinks from each project's _Required and _Default log buckets route logs to this bucket, ensuring centralized, immutable storage.

Granting the security team Storage Object Admin allows them to manage the bucket while restricting others.

Exam trap

Google Cloud often tests the misconception that BigQuery datasets can enforce immutability or that lifecycle rules alone prevent user deletion, when in fact Cloud Storage retention policies and Object Hold are required for true write-once-read-many (WORM) compliance.

How to eliminate wrong answers

Option A is wrong because a lifecycle rule that deletes objects after 5 years does not prevent deletion by users; it only automates deletion after the period, and denying storage.objects.delete to all except security team is not sufficient because project administrators could still delete objects if they have other permissions (e.g., Storage Admin) that override the deny. Option B is wrong because BigQuery datasets do not support immutable retention policies or object-level locks; table expiration only deletes data after 5 years but does not prevent deletion or modification by dataset owners or project administrators with BigQuery Data Editor or Owner roles. Option C is wrong because an organization-level log sink exports logs to BigQuery, which lacks immutability features; granting BigQuery Data Owner to security team still allows other users with inherited roles (e.g., project-level BigQuery Admin) to modify or delete data, and removing project administrators from dataset permissions does not prevent deletion by those with higher-level roles.

A company uses multiple Google Cloud projects. A service account in Project A needs to read data from a Cloud Storage bucket in Project B. What is the correct way to grant access?

A.Make the bucket publicly accessible and use signed URLs.

B.Grant the service account the Project Viewer role on Project B.

C.Add the service account as a member of Project B with the Storage Object Viewer role.

D.Add the service account as a member of the bucket's IAM policy with the Storage Object Viewer role.

AnswerD

This grants least-privilege access specifically to the bucket.

Why this answer

Option D is correct because Cloud Storage uses IAM policies at the resource (bucket) level to grant cross-project access. By adding the service account from Project A as a member of the bucket's IAM policy in Project B with the Storage Object Viewer role, you grant the service account read-only access to objects in that bucket without requiring membership in Project B itself. This follows the principle of least privilege and avoids unnecessary project-level permissions.

Exam trap

The trap here is that candidates often confuse project-level IAM roles with resource-level IAM roles, assuming that adding a service account as a member of the target project is necessary, when in fact Cloud Storage supports direct resource-level IAM binding for cross-project access.

How to eliminate wrong answers

Option A is wrong because making the bucket publicly accessible exposes data to the entire internet, which violates security best practices and is unnecessary for granting access to a specific service account. Option B is wrong because the Project Viewer role grants read-only access to all resources in Project B, which is overly permissive and does not specifically grant access to the bucket's objects. Option C is wrong because adding the service account as a member of Project B with the Storage Object Viewer role grants the role at the project level, which applies to all buckets in Project B, violating least privilege and potentially granting unintended access.

Which TWO of the following are valid ways to grant cross-project access to a Cloud Storage bucket in Project A from a Compute Engine VM in Project B?

Select 2 answers

A.Disable uniform bucket-level access on the bucket and add an ACL entry for the VM's service account.

B.Grant the VM's service account (from Project B) the roles/storage.objectViewer role on the bucket in Project A.

C.Grant the VM's user account the roles/storage.objectViewer role on the bucket, and have the VM use gcloud with the user's credentials.

D.Use an IAM condition on the bucket that allows access only when the requester is the service account from Project B.

E.Provide the bucket's service account key to the VM and have the VM use that key for authentication.

AnswersB, D

Direct role grant to the service account is valid.

Why this answer

Option B is correct because granting the VM's service account the roles/storage.objectViewer role on the bucket in Project A uses IAM-based cross-project access. IAM roles are the recommended method for granting access to resources across projects, as they allow a service account from one project to be granted permissions on resources in another project without needing to share keys or disable uniform bucket-level access.

Exam trap

Google Cloud often tests the misconception that ACLs or sharing service account keys are valid cross-project access methods, when in fact IAM roles and IAM conditions are the only supported mechanisms for granting cross-project access to Cloud Storage buckets.

A company is deploying a multi-region application in Cloud Run and must comply with data residency requirements in the European Union (EU). They want to ensure that only EU-based Cloud Run instances are created. Which approach should they use?

A.Add a label to the Cloud Run service specifying the region and rely on developers to follow it.

B.Set an Organization Policy with constraints/gcp.resourceLocations to restrict allowed regions to EU regions.

C.Use VPC Service Controls to limit access to the Cloud Run service from outside the EU.

D.Configure VPC Firewall rules to only allow egress to EU IP addresses.

AnswerB

This policy will prevent creation of Cloud Run services outside the allowed regions.

Why this answer

Option B is correct because Organization Policies with the `constraints/gcp.resourceLocations` constraint allow administrators to enforce a list of allowed Google Cloud regions for resource creation. By setting this policy to include only EU-based regions (e.g., `europe-west1`, `europe-west4`), the company ensures that Cloud Run instances cannot be created outside the EU, directly meeting data residency compliance requirements. This is a preventive control that applies at the project or folder level, overriding any developer choices.

Exam trap

The trap here is that candidates confuse network-level controls (VPC Service Controls, Firewall rules) with resource location enforcement, thinking that restricting access or egress to EU IPs is equivalent to ensuring resources are physically created in EU regions.

How to eliminate wrong answers

Option A is wrong because relying on labels and developer discipline is not an enforceable compliance control; labels are metadata and do not prevent resource creation in non-EU regions. Option C is wrong because VPC Service Controls restrict data exfiltration and access to services from outside a VPC perimeter, but they do not restrict the geographic location where Cloud Run instances are created; they control network access, not resource placement. Option D is wrong because VPC Firewall rules control network traffic based on IP addresses, not the location of resource creation; they cannot prevent a Cloud Run service from being deployed in a non-EU region, and EU IP ranges do not map cleanly to region-based compliance requirements.

A company wants to grant a user the ability to delete a Cloud SQL instance but not be able to modify any other settings. What is the least privileged role?

A.roles/cloudsql.viewer

B.roles/cloudsql.editor

C.roles/cloudsql.admin

D.Use a custom role with only cloudsql.instances.delete permission.

AnswerD

A custom role with this single permission meets the requirement exactly.

Why this answer

Option D is correct because the least privileged role that allows deleting a Cloud SQL instance without granting any other permissions is a custom role containing only the `cloudsql.instances.delete` permission. Predefined roles like viewer, editor, or admin include broader permissions that would allow modifying other settings, violating the principle of least privilege.

Exam trap

The trap here is that candidates may assume a predefined role like `roles/cloudsql.editor` is the least privileged because it includes delete, but they overlook that it also grants modify permissions, which violates the 'least privileged' requirement.

How to eliminate wrong answers

Option A is wrong because `roles/cloudsql.viewer` only grants read-only permissions (e.g., `cloudsql.instances.get`) and does not include the `cloudsql.instances.delete` permission, so it cannot delete an instance. Option B is wrong because `roles/cloudsql.editor` includes permissions to modify instance settings (e.g., `cloudsql.instances.update`) in addition to delete, which exceeds the requirement. Option C is wrong because `roles/cloudsql.admin` grants full control over Cloud SQL instances, including all create, update, and delete permissions, far beyond the single delete action needed.

Your company is deploying a web application on Google Kubernetes Engine (GKE) with an Internal Load Balancer (ILB) as the ingress. The application must only be accessible from within the same VPC and from an on-premises network connected via Cloud VPN. The on-premises network uses IP range 10.0.0.0/8. You have already created the ILB with a backend service. What is the most secure way to restrict access to the ILB?

A.Configure a VPC firewall rule to deny all ingress traffic to the ILB's forwarding rule IP address, and then create a higher-priority allow rule for the VPC and on-premises ranges

B.Configure the backend service's firewall rules to only allow traffic from the ILB's health check ranges and from the VPC and on-premises source ranges

C.Use GKE Network Policy to restrict ingress traffic to the application pods from the VPC and on-premises ranges

D.Use Cloud Armor to create a security policy that allows traffic only from the VPC and on-premises ranges, and attach it to the ILB

AnswerB

Correct: Firewall rules on the backend instances allow traffic from the ILB's health check probes and from permitted source ranges, ensuring only desired traffic reaches the application.

Why this answer

Option B is correct because the most secure way to restrict access to an Internal Load Balancer (ILB) is to apply firewall rules directly on the backend service (the instance group or NEG). This ensures that only traffic from the ILB's health check probe ranges (130.211.0.0/22 and 35.191.0.0/16 for GKE) and the allowed source ranges (VPC and on-premises) can reach the backend instances. This approach prevents any traffic from reaching the backend except through the ILB, which is the intended secure design for an internal-only application.

Exam trap

Google Cloud often tests the misconception that VPC firewall rules can be applied to a load balancer's forwarding rule IP address, but in reality, firewall rules only apply to VM instances or GKE nodes, not to forwarding rules or load balancer IPs.

How to eliminate wrong answers

Option A is wrong because VPC firewall rules cannot be applied to the ILB's forwarding rule IP address; forwarding rules are not network interfaces and are not subject to VPC firewall rules. Option C is wrong because GKE Network Policy operates at the pod level and cannot restrict traffic to the ILB itself; it only controls traffic between pods, not traffic arriving via the ILB. Option D is wrong because Cloud Armor security policies cannot be attached to an Internal Load Balancer; Cloud Armor only supports external load balancers (HTTP(S), SSL Proxy, TCP Proxy) and not ILBs.

A company is using Cloud NAT to allow instances in a private subnet to access the internet. They notice that some instances are unable to reach external services. The NAT gateway is configured with a single IP address. Which action would most likely resolve the issue?

A.Change the NAT type to static

B.Change the VPC firewall rules to allow egress from the NAT IP

C.Increase the number of NAT IPs

D.Enable TCP established connections only

AnswerC

More NAT IPs increase available ports, reducing the chance of port exhaustion.

Why this answer

The issue is that a single NAT IP address can run out of available ports (each TCP/UDP session consumes a unique source port), causing new connections to fail. Increasing the number of NAT IPs expands the port pool, allowing more concurrent outbound connections. This directly addresses the port exhaustion problem without changing firewall rules or NAT type.

Exam trap

Google Cloud often tests the misconception that firewall rules or NAT type changes fix connectivity issues, when the real problem is port exhaustion from a single NAT IP under heavy connection load.

How to eliminate wrong answers

Option A is wrong because Cloud NAT does not have a 'static' type; the NAT type is either public (with ephemeral or static IPs) or private, and changing the type does not resolve port exhaustion. Option B is wrong because VPC firewall rules control traffic based on source/destination IPs and ports, but the NAT IP is the source IP for outbound traffic; egress rules must allow traffic from the instances' private IPs (or the NAT IP), but the issue is port capacity, not firewall blocking. Option D is wrong because 'TCP established connections only' is a firewall rule concept (e.g., connection tracking) and does not apply to NAT gateway configuration; Cloud NAT handles all protocols and does not have a setting to limit to established connections.

A company wants to implement least privilege access for a team that needs to monitor and manage Cloud Run services. Which two IAM roles should be considered? (Choose two.)

Select 2 answers

A.roles/iam.serviceAccountUser

B.roles/run.admin

C.roles/run.viewer

D.roles/run.developer

E.roles/run.invoker

AnswersC, D

Allows viewing services and configurations.

Why this answer

Option C (roles/run.viewer) is correct because it grants read-only permissions to view Cloud Run services, configurations, and revisions, which is sufficient for monitoring without allowing modifications. Option D (roles/run.developer) is correct because it allows both viewing and managing Cloud Run services (e.g., deploying new revisions, updating configurations) while still restricting access to other GCP resources, aligning with least privilege for a team that needs to both monitor and manage.

Exam trap

Google Cloud often tests the distinction between 'viewer' and 'developer' roles, where candidates mistakenly choose 'run.admin' thinking it is needed for management, or 'run.invoker' thinking it covers monitoring, but the exam expects precise matching of permissions to the tasks of monitoring (read-only) and managing (deploy/update) without full administrative control.

A security team wants to ensure that all service account key creation events in their organization are logged and alerted on. Which logging feature should they use?

A.Enable System Event audit logs for the IAM service.

B.Enable Data Access audit logs for the IAM service.

C.Enable Access Transparency logs for the IAM service.

D.Enable Admin Activity audit logs for the IAM service.

AnswerD

Admin Activity logs record all administrative actions, including creating keys.

Why this answer

Admin Activity audit logs capture operations that modify the configuration or metadata of resources, such as creating or deleting service account keys. Since the question asks about logging key creation events, Admin Activity logs are the correct choice because they record all administrative actions, including service account key creation, by default and cannot be disabled. Data Access audit logs, by contrast, track data-level operations like reading or writing data, not administrative changes.

Exam trap

Google Cloud often tests the distinction between Admin Activity and Data Access logs, where candidates mistakenly choose Data Access for any security-related logging, not realizing that key creation is an administrative action, not a data access operation.

How to eliminate wrong answers

Option A is wrong because System Event audit logs are not a valid log type in Google Cloud; the correct log categories are Admin Activity, Data Access, and Access Transparency. Option B is wrong because Data Access audit logs record operations that read or modify user-provided data, such as reading objects in Cloud Storage, not administrative actions like creating service account keys. Option C is wrong because Access Transparency logs capture actions taken by Google personnel when accessing your data, not actions performed by your own service accounts or administrators.
