CCNA Managing operations in a cloud solution environment Questions

Option C is correct. The error message explicitly states that the image family does not exist in the specified project. Option A is possible, but the error specifically says the image family does not exist.

Option B would result in a permission denied error, not this error. Option D is incorrect because the project ID is specified in the image path; if it were wrong, the error would indicate an invalid project.

Option D is correct because methodName is 'v1.compute.instances.delete', indicating a delete operation, and the principal is admin@example.com. Option A is incorrect because the method is delete, not create. Option B is incorrect because the method is delete, not modify.

Option C is incorrect because the method is delete, not update.

Options A, C, and D are correct. Using Secret Manager, IAM binding, and short-lived secrets via Secret Manager with rotation. Option B is incorrect because storing secrets in Cloud Storage even encrypted is less secure than Secret Manager.

Option E is incorrect because hardcoding secrets in source code is dangerous.

Option C is correct because Cloud Logging and Cloud Monitoring natively integrate with GKE and provide logs, metrics, and traces in a unified dashboard. Option A is wrong because Stackdriver Logging and Monitoring are the former names of Cloud Logging and Monitoring; they are the same service but the answer refers to outdated names. Option B is wrong because Prometheus requires manual setup and does not provide native GKE integration for all signals.

Option D is wrong because third-party tools add complexity and may not integrate as seamlessly.

Option C is correct. The deny-all rule (priority 2000) has a higher priority (lower number) than the default-allow-internal rule (priority 65534). Since the deny-all rule blocks all TCP traffic from the 10.0.0.0/8 range, it overrides the default-allow-internal rule, blocking SSH traffic from 10.0.0.4 to 10.128.0.5.

Option A is incorrect because the deny rule denies traffic from 10.0.0.0/8, not to it. Option B is incorrect because default-allow-internal allows all TCP traffic. Option D is incorrect because default-allow-internal covers SSH; the issue is priority.

Option A is correct because if a deny rule with a lower priority number (higher priority) exists, it will take precedence and block traffic despite an allow rule. Option B is incorrect because the instance's internal IP address does not affect the source range check. Option C is incorrect because the problem states the target tag is set correctly.

Option D is incorrect because the rule is in the correct network.

Options A and C are correct. Admin Activity audit logs are always enabled by default and cannot be disabled. System Event audit logs are also enabled but capture Google Cloud actions.

Option B is incorrect because Data Access logs are disabled by default and need to be enabled. Option D is incorrect because Cloud Audit Logs do NOT include metrics, only logs. Option E is incorrect because all audit logs are retained for 400 days by default.

Option D is correct because Secret Manager provides a centralized, durable, and scalable solution for storing and managing secrets across projects. Option A is wrong because storing secrets in Cloud Storage with encryption still requires managing access and does not offer built-in versioning or rotation. Option B is wrong because hardcoding secrets in code is insecure.

Option C is wrong because Cloud KMS is for managing encryption keys, not secrets.

Option B is correct because if a deny rule with a lower priority number (higher priority) exists, it will block traffic despite the allow rule. Option A is incorrect because sourceRanges includes all IPs. Option C is incorrect because the rule targets the correct tags.

Option D is incorrect because direction is correctly INGRESS for incoming traffic.

A CI/CD pipeline with Cloud Build can include manual approval gates that block deployments until approved. This enforces change review while allowing development to proceed. Option A is incorrect because organization policies would block all Deployment Manager usage, including in development.

Option C is incorrect because auditing only monitors changes but does not prevent them. Option D is incorrect because snapshots allow rollback but do not prevent unapproved changes.

Option C is correct because hierarchical firewall rules can be applied at the folder or organization level, allowing central management. Option A is incorrect because global VPC firewall rules still need to be applied per network or per project. Option B is incorrect because Organization Policies do not manage firewall rules.

Option D is incorrect because Shared VPC does not enforce rules on all projects.

Options A and D are correct. Cloud Functions can subscribe to SCC notifications via Pub/Sub, and Eventarc triggers can react to findings. Option B is incorrect because Cloud Scheduler is for scheduled jobs.

Option C is incorrect because Cloud Run does not directly integrate with SCC. Option E is incorrect because Cloud Tasks is for task distribution, not direct response.

Options A and B are correct. To block requests by geography in Cloud Armor, you create a security policy with a geo-match condition (A) and then attach that policy to the backend service (B). Option C is incorrect because the deny rule should have a higher priority (lower number) than the default rule, not lower.

Option D is unnecessary. Option E is incorrect because Cloud CDN geo-restrictions affect caching, not request blocking.

Option D is correct because combining Binary Authorization with Attestations from vulnerability and signing enables enforcement. Option A is incorrect because Cloud Nat is for outbound traffic, not image enforcement. Option B is incorrect because GKE policy does not natively enforce image contracts.

Option C is incorrect because IAP is for access, not for image verification.

Option C is correct because health check failures can cause traffic to be routed to unhealthy backends, leading to latency. Option A is wrong because increasing instance size may help but is not the first step. Option B is wrong because adding more zones distributes load but doesn't address underlying health.

Option D is wrong because changing SSL policy affects encryption, not latency.

Option A is correct because Admin Activity audit logs capture all setIamPolicy calls, and exporting them to BigQuery allows for powerful querying to detect specific changes. Option B is incorrect because Cloud Asset Inventory can monitor policy changes but setting up feeds and triggers is more complex. Option C is incorrect because Data Access audit logs are for data access, not admin changes.

Option D is incorrect because VPC Service Controls are for perimeter security, not auditing.

Option B is correct because retention policies with Object holds ensure minimum retention. Option A is incorrect because bucket lock is for permanent immutability, not flexible retention. Option C is incorrect because versioning alone does not prevent deletion; it allows recovery but does not block deletion.

Option D is incorrect because lifecycle management only transitions or deletes based on age, not prevents.

Options B and D are correct. Creating custom service accounts with only the needed roles (B) ensures minimal permissions. Disabling service account key creation (D) reduces the risk of key exposure.

Option A is incorrect because the default compute service account often has excessive permissions. Option C is incorrect because Access Transparency is for auditing Google support access. Option E is incorrect because attaching a service account after instance creation is possible but not a best practice for minimal permissions; it should be assigned at creation.

Option C is correct because GCP VPC firewall rules have an implied deny at the end; therefore, allowing only the health check traffic and relying on the implied deny for other traffic is the simplest and most secure approach. Option A is incorrect because a deny rule with higher priority than an allow rule would block the allowed traffic. Option B is incorrect because target tags are useful but do not directly address restricting internal subnet traffic.

Option D is incorrect because hierarchical policies are for organization-level rules, not for this specific subnet restriction.

Option C is correct because if the backend service has an external IP address and a firewall rule allowing public access, users can bypass IAP entirely. Option A would actually grant legitimate access. Option B would cause IAP to fail for all users.

Option D is a legitimate way to grant access.

Option B is correct because the gcloud sql backups restore command can restore a backup to a new instance, even if the original instance was deleted. Option A is incorrect because importing a backup is a manual process that requires creating an instance first, which is less direct. Option C is incorrect because restoration is possible.

Option D is incorrect because the Cloud Console does not support restoring a deleted instance directly.

Options A and C are correct. Disabling public access stops further exfiltration, and creating a copy preserves the bucket's data for forensics. Removing IAM policies (B) may disrupt analysis.

Enabling logs (D) after the breach won't capture past events. Deleting the bucket (E) destroys evidence.

Option D is correct because Organization Policies can enforce constraints like disabling automatic key creation or setting key expiration. Option A is incorrect because IAM itself does not have lifecycle policies. Option B is incorrect because Secret Manager does not manage service account keys.

Option C is incorrect because Cloud Key Management Service does not manage service account keys.

Option C is correct because IAP TCP forwarding logs are available as Admin Activity audit logs when IAP is used for SSH. Option A is incorrect because guest attributes are not for audit logs. Option B is incorrect because Cloud Monitoring does not directly log SSH attempts.

Option D is incorrect because Serial port access logs are separate and not for IAP.

Option D is correct. Cloud NAT has a limit on the number of concurrent connections per NAT IP due to port exhaustion. When many connections are made, ports can be exhausted, causing intermittent failures.

Option A is incorrect because Cloud NAT supports UDP. Option B is a potential cause but the specific failure mode is port exhaustion. Option C is unlikely because outbound traffic is typically allowed by default.

Option D is correct. The best practice is to delete the key and use workload identity federation, which eliminates the need for long-lived keys. Option A is not directly relevant.

Option B is partially true, but rotation alone is not as secure as eliminating the key. Option C is not a standard best practice.

Option D is correct because Cloud Functions has a maximum timeout of 60 minutes (540 seconds) for HTTP functions; increasing the timeout to 120 seconds and optimizing code can resolve the timeout. Option A is wrong because changing the runtime won't inherently reduce execution time. Option B is wrong because Cloud Run has a similar timeout but also requires code changes; it's more complex than adjusting the function.

Option C is wrong because increasing memory alone may improve performance but does not extend timeout beyond 60 seconds.

Option A is correct because committed use discounts (CUDs) provide significant discounts in exchange for a 1- or 3-year commitment, ideal for steady-state workloads. Option B is wrong because preemptible VMs are not suitable for long-running batch jobs due to termination risk. Option C is wrong because custom machine types may optimize resource use but do not offer discounts like CUDs.

Option D is wrong because sole-tenant nodes isolate VMs but do not reduce costs.

Option B is correct. Cloud Asset Inventory provides a centralized view of all resources and their IAM policies across projects. Option A, Cloud Security Command Center, provides security findings and vulnerabilities, not a full inventory.

Option C, Access Transparency, logs Google support access. Option D, Cloud Audit Logs, records API calls but not a static inventory.

Option A is correct. The policy shows Alice has only the roles/storage.objectViewer role, which does not include delete permissions. Bob, although listed in the same binding, must have additional permissions from another policy (e.g., at the project level) that allow him to delete objects.

Option B is incorrect because Bob's ability is likely due to inherited permissions, but the exhibit only shows this policy. Option C is irrelevant because the service account does not affect Bob's permissions. Option D is incorrect; etag is used for concurrent modification prevention.

Option B is correct because Cloud Monitoring alerts can trigger a webhook or pub/sub to integrate with ticketing systems. Option A is incorrect because Cloud Functions require manual triggering or scheduling, not real-time alert. Option C is incorrect because Cloud Scheduler runs on a schedule, not based on metric thresholds.

Option D is incorrect because Cloud Tasks is for asynchronous task execution, not directly for alerting.

Option A is correct because shared VPC allows separate projects (dev and prod) to use a common host VPC with consistent security policies. Option B is wrong because separate projects with VPC peering do not enforce shared security policies centrally. Option C is wrong because firewall rules alone cannot create separate networks.

Option D is wrong because VPC peering does not provide centralized policy management.

Option B is correct because alert policies are project-scoped resources. If the VM instances reside in a different project than the one where the alert policy is defined, the policy cannot monitor those instances. The MQL query references the metric `compute.googleapis.com/instance/cpu/utilization` which is only visible within the same project as the monitored resources.

Cross-project monitoring requires additional configuration such as a metrics scope or a separate alert policy in the target project.

Option C is correct because Cloud Spanner offers global transactional consistency, horizontal scaling, and multi-region configurations for data residency. Option A is wrong because BigQuery is for analytics, not operational transactions. Option B is wrong because Cloud SQL in a single region cannot serve global reads with low latency.

Option D is wrong because Firestore in multi-region does not guarantee strong consistency for all operations.

Options B and D are correct. A request is allowed if it originates from a project within the perimeter and meets the required access levels. Option A is not a direct condition; IP ranges are part of access levels.

Option C is not a standalone condition; service accounts are allowed based on identity and access levels. Option E is also part of access levels.

Option A is correct because Cloud SQL automated backups and binary log (WAL) archiving enable point-in-time recovery. Option B is incorrect because export to Cloud Storage is a manual process. Option C is incorrect because snapshots are not supported for Cloud SQL.

Option D is incorrect because manual backups do not provide point-in-time recovery.

The most likely cause is that custom route exchange is not enabled on the VPC Network Peering connection. By default, VPC peering does not exchange custom routes (including subnet routes) unless explicitly enabled. Without this, VPC-B has no route to the 10.1.0.0/16 subnet of VPC-A, so the instance in VPC-B cannot send traffic to 10.1.0.2, even though firewall rules allow ingress.

The peering connection being active only means the link is established, not that routes are automatically propagated.

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.

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.

Options A, B, and D are correct. Cloud Logging ingests logs, Cloud Storage with Object Lock provides immutability, and BigQuery allows querying. Option C is a type of log, not a service.

Option E is for security findings, not log management.

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.

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.

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.

Options B, C, and E are correct. You need to set a rotation period on the Cloud KMS key (B), enable automatic rotation (C), and re-encrypt any data encrypted with older versions using the new key version (E) to ensure data is protected by the new key. Option A is incorrect because rotation should be automatic.

Option D is incorrect because old key versions should not be destroyed immediately; they are needed to decrypt existing data. Option F is unnecessary because automatic rotation is a built-in feature.

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.

Option D is wrong because CDN affects content delivery, not backend connectivity.

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. Option C is incorrect because disabling public access at the organization level might be too broad and impact legitimate needs.

Option D is incorrect because relying on documentation is not preventive.

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.

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.
