Cloud Digital Leader Trust and security with Google Cloud Practice Test 3 — 15 Questions

Question 1

A company's security team wants to ensure that only approved corporate devices can access Google Cloud resources, regardless of whether the user has valid credentials. Which Google Cloud security capability enforces device-level access requirements?

Accepted Answer

Access Context Manager, which enforces device-level access requirements as part of context-aware access control policies. Access Context Manager is the correct choice because it allows security teams to define context-aware access policies that include device-level attributes such as device OS type, device ID, and whether the device is managed (e.g., via endpoint verification or third-party EMM). This enforces device-level access requirements even if the user has valid credentials, directly addressing the scenario.

Answer

Cloud Armor, which filters incoming requests based on IP allowlists and denylists

Answer

Identity-Aware Proxy (IAP), which provides application-level authentication but without device checks

Answer

VPC Service Controls, which restrict access to Google APIs based on network perimeter membership

Question 2

A financial services company is subject to regulations requiring them to demonstrate that their cloud provider's employees cannot access customer data without the customer's explicit approval. Which Google Cloud feature most directly addresses this requirement?

Accepted Answer

Access Transparency and Access Approval, which log and require explicit customer approval for Google personnel access to customer content. Access Transparency and Access Approval directly address the regulatory requirement by providing near real-time logs of Google personnel actions on customer content and requiring explicit customer approval before such access can occur. Access Transparency logs every access attempt by Google employees, while Access Approval allows customers to approve or deny those requests, ensuring no unauthorized access without customer consent.

Answer

Customer-Managed Encryption Keys (CMEK), where the customer controls the encryption key and can revoke access

Answer

Cloud Audit Logs, which record all customer actions within Google Cloud

Answer

VPC Service Controls, which prevent Google employees from accessing resources inside the service perimeter

Question 3

A security team is reviewing a developer's request to be granted the 'Owner' role on a production Google Cloud project 'just in case they need broad access.' The security team rejects this and instead grants a more specific role. Which security principle does the security team's decision enforce?

Accepted Answer

Principle of least privilege, by granting only the minimum permissions necessary for the developer's specific role and tasks. The security team's decision to reject the overly broad 'Owner' role and grant a more specific role directly enforces the principle of least privilege. This principle dictates that users should be granted only the minimum permissions necessary to perform their job functions, reducing the risk of accidental or malicious misuse of elevated access. In Google Cloud, this is implemented by assigning predefined or custom IAM roles with precisely scoped permissions rather than broad roles like Owner.

Answer

Defense in depth, by ensuring multiple security layers protect the project

Answer

Separation of duties, by ensuring no single person has too many responsibilities

Answer

Zero trust networking, by treating the developer's device as untrusted

Question 4

A company is moving a regulated workload to Google Cloud and must ensure that their encryption keys are stored in a hardware security module (HSM) that meets FIPS 140-2 Level 3 validation. Which Google Cloud key management option satisfies this requirement?

Accepted Answer

Cloud HSM, which stores and manages keys in FIPS 140-2 Level 3 validated hardware security modules. Cloud HSM is the correct choice because it provides a dedicated HSM service that stores and manages encryption keys in FIPS 140-2 Level 3 validated hardware security modules. This directly meets the regulatory requirement for a hardware security module with that specific validation level, as opposed to software-backed or customer-supplied key options.

Answer

Cloud KMS software-backed keys, which are managed by Google and stored in Google's secure key management infrastructure

Answer

Customer-supplied encryption keys (CSEK), where the customer provides the key with each API request

Answer

Secret Manager, which stores API keys and credentials with automatic rotation

Question 5

A company has employees who use personal (unmanaged) devices to access corporate applications. The security team wants to prevent sensitive Google Workspace documents from being downloaded to personal devices. Which Google control most directly addresses this data loss prevention requirement for device-based scenarios?

Accepted Answer

Google Workspace context-aware access and endpoint management controls that restrict actions (such as downloads) for users accessing from unmanaged personal devices. Option B is correct because Google Workspace context-aware access combined with endpoint management allows administrators to create access level policies that restrict specific actions—such as downloading, printing, or copying—based on device trust signals. When a user accesses Google Workspace from an unmanaged personal device, the policy can block the download of sensitive documents directly, addressing the data loss prevention requirement at the action level rather than just the access level.

Answer

Cloud Armor, by blocking requests from IP addresses associated with personal devices

Answer

Enabling two-factor authentication for all users, which prevents unauthorized access

Answer

Encrypting all Google Drive files so they cannot be read on personal devices

Question 6

A startup is building a web application and wants to protect it from common web attacks like SQL injection and cross-site scripting. Which Google Cloud product provides web application firewall (WAF) capabilities?

Accepted Answer

Cloud Armor, which provides WAF rules to detect and block SQL injection, XSS, and other OWASP Top 10 attacks. Cloud Armor is Google Cloud's web application firewall (WAF) service that provides pre-configured rules to detect and block common web attacks, including SQL injection and cross-site scripting (XSS), as well as other OWASP Top 10 threats. It integrates with Cloud Load Balancing and allows you to create custom security policies with rate limiting, IP allow/deny lists, and managed rule sets. This makes it the correct choice for protecting a web application at the application layer.

Answer

Cloud Firewall, which controls network-level traffic based on IP and port rules

Answer

VPC Service Controls, which prevent data exfiltration from Google Cloud services

Answer

Security Command Center, which detects security misconfigurations across Google Cloud resources

Question 7

An organization wants to ensure that Google Cloud services used by its employees cannot be used to exfiltrate data to a competitor's Google Cloud project. For example, they want to prevent copying data from their Cloud Storage bucket to a Storage bucket owned by a competitor. Which Google Cloud security control most directly prevents this type of insider data exfiltration?

Accepted Answer

VPC Service Controls, which create a security perimeter around Google Cloud APIs so data cannot be moved to projects outside the defined perimeter. VPC Service Controls (C) directly prevent data exfiltration by creating a security perimeter around Google Cloud APIs. This perimeter blocks any data movement to resources outside the defined perimeter, such as a competitor's Cloud Storage bucket, regardless of the user's IAM permissions. It works at the API layer, intercepting requests that attempt to copy data to an unauthorized project.

Answer

IAM permissions that restrict users from accessing competitor projects

Answer

Cloud DLP, by scanning and redacting sensitive data before it can be stored

Answer

Organization Policy constraints that prevent resource creation in competitor accounts

Question 8

A company has migrated sensitive customer data to Google Cloud. The legal team asks: 'If Google is hosting our data, who is responsible for ensuring that data is not improperly accessed by unauthorized users through our application?' Under the shared responsibility model, how should the CTO answer?

Accepted Answer

The customer is responsible for application access controls, authentication, and IAM policies that protect data from unauthorized application-layer access, while Google secures the underlying infrastructure. Option B is correct because under the Google Cloud shared responsibility model, the customer is responsible for securing access to their application and data, including authentication, authorization, and IAM policies, while Google is responsible for the security of the underlying infrastructure (physical security, network, hypervisor). The legal team's question specifically asks about unauthorized access through the customer's application, which falls under the customer's responsibility for application-layer controls.

Answer

Google is fully responsible because they host the data and control the infrastructure

Answer

Both Google and the customer share equal 50/50 responsibility for all data access controls

Answer

No one is responsible because cloud computing inherently cannot prevent unauthorized access

Question 9

A company's security policy requires that all cloud-to-cloud communication between services must be encrypted in transit. An auditor asks how Google Cloud handles encryption for network traffic between Google services within its network. What is Google's default approach to encryption in transit within its infrastructure?

Accepted Answer

Google encrypts all traffic between its data centers and internal services by default, with no customer configuration required. Google Cloud encrypts all network traffic between its data centers and internal services by default, using application-layer (e.g., gRPC with TLS) and link-layer encryption (e.g., MACsec or similar). This is a foundational security measure that requires no customer configuration, ensuring data is protected in transit even within Google's own infrastructure.

Answer

Google does not encrypt internal traffic by default; customers must configure TLS for all service-to-service communication

Answer

Google only encrypts traffic that crosses the public internet; internal network traffic is unencrypted for performance

Answer

Encryption in transit is the customer's responsibility for all traffic, including traffic within Google's network

Question 10

A CISO is evaluating Google Cloud's security posture and asks about independent third-party validation of Google's security practices. Which types of certifications and audit reports most directly provide this independent assurance?

Accepted Answer

Third-party audit certifications such as ISO 27001, SOC 2 Type II, PCI DSS, and FedRAMP, which independently verify that Google's security controls meet defined international and industry standards. Option B is correct because independent third-party validation of Google Cloud's security posture is most directly provided by certifications and audit reports such as ISO 27001, SOC 2 Type II, PCI DSS, and FedRAMP. These are issued by accredited external auditors who verify that Google's security controls, processes, and infrastructure meet rigorous, internationally recognized standards. This gives customers objective assurance beyond Google's own claims.

Answer

Google's internal security policies and self-assessment reports published on its website

Answer

Google's Bug Bounty program, which shows that the public can report security vulnerabilities

Answer

Customer testimonials from large enterprises that use Google Cloud for sensitive workloads

Question 11

A company's security team wants to be alerted when someone with administrative permissions changes an IAM policy in their Google Cloud organization. Which Google Cloud capability enables this detection?

Accepted Answer

Admin Activity audit logs combined with Cloud Monitoring log-based alerting, which records and alerts on IAM policy modifications by any principal. Admin Activity audit logs record all changes to IAM policies and other configuration changes in Google Cloud. By combining these logs with Cloud Monitoring log-based alerting, the security team can create a specific alert that triggers whenever an IAM policy is modified by a principal with administrative permissions, enabling real-time detection of unauthorized changes.

Answer

Data Access audit logs, which record when data is read from Cloud Storage buckets

Answer

Cloud Armor, which blocks unauthorized IAM policy changes at the network layer

Answer

VPC flow logs, which capture all network traffic including IAM API calls

Question 12

A multinational company must ensure that personal data of European citizens stored in Google Cloud cannot be accessed by or transferred to systems outside the European Union, as required by GDPR data residency requirements. Which Google Cloud controls most directly enforce this?

Accepted Answer

Configuring organization policy to restrict resource creation to EU regions, using VPC Service Controls to prevent data movement outside the EU perimeter, and establishing a GDPR-compliant Data Processing Agreement with Google. Option B is correct because it combines three essential controls that directly enforce GDPR data residency: Organization Policies restrict resource creation to EU regions, VPC Service Controls create a data perimeter preventing exfiltration outside the EU, and a GDPR-compliant Data Processing Agreement (DPA) establishes the legal framework for data handling. These controls work together to ensure data at rest and in transit remains within the EU boundary, directly addressing the residency requirement.

Answer

Enabling HTTPS for all data transmission to ensure data is encrypted during transfer

Answer

Using Customer-Managed Encryption Keys (CMEK) where the encryption keys are stored outside Google's infrastructure

Answer

Training developers about GDPR requirements and requiring manual approval for any cross-region data transfers

Question 13

A security audit finds that a company's application service accounts have been granted broad IAM roles (e.g., Storage Admin on the entire project) when they only need to read specific Cloud Storage buckets. The auditor recommends following the principle of least privilege. What is the most precise way to implement this for the Cloud Storage use case?

Accepted Answer

Grant Storage Object Viewer (read-only) at the specific bucket level for each service account that needs read access — not at the project level. Option B is correct because it grants the minimal required permission (Storage Object Viewer) at the specific bucket level, adhering to the principle of least privilege. This ensures the service account can only read objects in that bucket and cannot perform any other storage operations, even accidentally. Granting roles at the resource level (bucket) rather than the project level eliminates unnecessary broad access.

Answer

Grant the Storage Admin role at the project level but add a condition that limits it to specific operations

Answer

Create a custom IAM role that combines all permissions from all predefined roles but removes the most dangerous ones

Answer

Use the same broad Storage Admin role but rotate the service account key every 90 days to reduce the window of exposure

Question 14

An enterprise's security team is implementing a strategy to protect against 'credential stuffing' attacks — where attackers use lists of username/password combinations from previous data breaches to try to log in to the company's applications. Which authentication control most effectively mitigates this threat?

Accepted Answer

Multi-Factor Authentication (MFA/2SV), which requires a second verification factor beyond the password that attackers don't have even when they possess the stolen credentials. Multi-Factor Authentication (MFA/2SV) is the most effective control against credential stuffing because it requires an additional verification factor (e.g., a one-time code from an authenticator app, a hardware token, or a biometric) that the attacker does not possess, even if they have valid username/password pairs from a breach. This renders the stolen credentials useless for authentication, as the attacker cannot complete the second factor challenge. In Google Cloud, this is commonly enforced via Identity Platform or Cloud Identity with security keys or TOTP.

Answer

Requiring longer, more complex passwords to make credentials harder to guess

Answer

Encrypting passwords in the company's database using bcrypt to prevent the stolen passwords from being usable

Answer

Implementing HTTPS on the login page to prevent credentials from being intercepted in transit

Question 15

A developer accidentally commits an application's Google Cloud service account key to a public GitHub repository. The key is valid and grants access to production resources. What is the correct immediate response?

Accepted Answer

Immediately revoke/delete the exposed service account key in Google Cloud IAM, review Cloud Audit Logs for unauthorized access, and generate a new key distributed through secure channels. Option B is correct because the immediate priority is to invalidate the exposed credential to prevent unauthorized access to production resources. Revoking the key in Google Cloud IAM ensures it can no longer be used for authentication, while reviewing Cloud Audit Logs helps identify any potential misuse. Generating a new key and distributing it securely restores access for legitimate applications.

Answer

Delete the commit from GitHub history using git rebase; the key is safe once removed from the repository

Answer

Change the service account's permissions to read-only to limit the damage from potential misuse

Answer

Send an internal email informing the security team and wait for their guidance before taking any action
