Test your knowledge of Google Cloud DevOps Engineer exam content

A software team needs to implement a CI/CD pipeline that automatically builds a container image from source code, runs tests, and deploys to GKE when code is pushed to the main branch.

Which Google Cloud tools should you use?

A) Cloud Build for CI/CD with build triggers, Container Registry or Artifact Registry for images, and GKE for deployment
B) Manual Docker builds on developer machines uploaded to GKE
C) Cloud Scheduler to periodically check for code changes
D) Cloud Functions to build and deploy container images

 

Correct answers: A – Explanation:
Cloud Build with triggers automates the full CI/CD pipeline from code push to deployment. Manual builds are not automated. Scheduled polling introduces delay. Cloud Functions are not designed for container builds and deployments.

A production service on GKE is experiencing intermittent 500 errors. The DevOps engineer needs to quickly identify the root cause.

Which Google Cloud observability tools should you use to diagnose the issue?

A) Cloud Logging for error logs, Cloud Monitoring for metrics and dashboards, and Cloud Trace for request latency analysis
B) Restarting all pods and hoping the issue resolves
C) Checking only the GKE node system logs without application logs
D) Running manual curl commands against the service endpoint

 

Correct answers: A – Explanation:
Logging, Monitoring, and Trace provide comprehensive visibility into errors, resource metrics, and request latency. Restarting pods masks the root cause. Node-only logs miss application-level errors. Manual curl tests do not provide systematic diagnostics.

A company wants to implement infrastructure as code for their Google Cloud environment, including VPCs, GKE clusters, and Cloud SQL instances.

Which tool should the DevOps engineer use?

A) Terraform with the Google Cloud provider for declarative, version-controlled infrastructure management
B) Creating all resources manually through the Cloud Console
C) Writing custom Python scripts using the Google Cloud API for each resource
D) Using Cloud Shell to run one-off gcloud commands documented in a wiki

 

Correct answers: A – Explanation:
Terraform provides declarative IaC with state management, drift detection, and version control. Console creation is not reproducible. Custom Python scripts require more maintenance than declarative IaC. Documented gcloud commands require manual execution.

After a production incident where a bad deployment caused an outage, the DevOps team needs to implement a deployment strategy that allows gradual rollout with automatic rollback.

Which deployment strategy should you implement?

A) Canary deployment with progressive traffic shifting and automatic rollback based on error rate thresholds
B) Big-bang deployment to all instances simultaneously
C) Blue-green deployment with manual traffic switching and no automated rollback
D) Deploying to production only on weekends with manual monitoring

 

Correct answers: A – Explanation:
Canary deployment with automated rollback limits blast radius and reverts automatically on errors. Big-bang exposes all users to bad code. Manual blue-green without automation delays rollback. Weekend-only deployment does not address automated safety.

A DevOps engineer needs to define and track Service Level Objectives (SLOs) for a production web service, with alerts when the error budget is being consumed too quickly.

Which Google Cloud tools support SLO management?

A) Cloud Monitoring with SLO definitions, error budget burn-rate alerts, and SLI-based dashboards
B) Manually calculating SLOs from monthly reports in a spreadsheet
C) Cloud Logging alerts for any single error occurrence
D) Using only uptime checks without error budget tracking

 

Correct answers: A – Explanation:
Cloud Monitoring provides native SLO configuration with burn-rate alerting and SLI dashboards. Manual spreadsheet calculations are delayed and error-prone. Alerting on every error creates noise. Uptime checks alone do not track error budgets.

A post-incident review reveals that the team lacked a structured approach to documenting incidents and identifying preventive measures.

What SRE practice should the DevOps engineer introduce?

A) Blameless postmortems with structured documentation of timeline, root cause, impact, and action items
B) Identifying the individual who caused the incident for accountability
C) Ignoring incidents that were resolved quickly
D) Writing detailed postmortems only for incidents lasting more than 24 hours

 

Correct answers: A – Explanation:
Blameless postmortems focus on systemic improvements rather than individual blame, encouraging transparency and learning. Individual blame discourages reporting. Ignoring quick incidents misses improvement opportunities. Arbitrary time thresholds miss impactful short incidents.

A DevOps team needs to manage secrets such as database passwords and API keys used by applications deployed on GKE.

Which approach should you use for secret management in GKE?

A) Store secrets in Secret Manager and mount them as volumes in GKE pods using the Secret Manager CSI driver
B) Hardcode secrets in the application’s Dockerfile
C) Store secrets as Kubernetes ConfigMaps in plain text
D) Cloud Functions to build and deploy container images

 

Correct answers: A – Explanation:
Secret Manager with CSI driver provides secure, auditable secret management integrated with GKE. Dockerfile hardcoding exposes secrets in images. ConfigMaps are not encrypted by default. Pipeline logs expose secrets to anyone with log access.

A GKE cluster needs to automatically scale the number of nodes based on pod resource requests when workload demand increases.

Which GKE feature should you enable?

A) Cluster Autoscaler that adds or removes nodes based on pending pod scheduling requirements
B) Manually adding nodes when CPU utilization is high
C) Horizontal Pod Autoscaler only without node scaling
D) Over-provisioning nodes at maximum capacity permanently

 

Correct answers: A – Explanation:
Cloud Build with triggers automates the full CI/CD pipeline from code push to deployment. Manual builds are not automated. Scheduled polling introduces delay. Cloud Functions are not designed for container builds and deployments.

A DevOps engineer wants to ensure that only container images that have passed vulnerability scanning can be deployed to the production GKE cluster.

Which Google Cloud feature enforces this policy?

A) Binary Authorization with attestation policies that allow only signed, scanned images
B) Deploying all images without scanning and monitoring for issues after deployment
C) Manual image review before each deployment by a security team member
D) Using only public Docker Hub images without scanning

 

Correct answers: A – Explanation:
Binary Authorization enforces that only attested (scanned, approved) images are deployed to production. Post-deployment monitoring is reactive. Manual review does not scale. Public images without scanning introduce unknown vulnerabilities.

A critical production service needs to maintain 99.9% availability. The DevOps team needs to determine how much downtime is acceptable per month and plan maintenance accordingly.

How should the team manage planned maintenance within the error budget?

A) Calculate the monthly error budget (approximately 43 minutes for 99.9%), schedule maintenance within this budget, and use rolling updates to minimize downtime
B) Schedule 8 hours of maintenance monthly regardless of SLO
C) Avoid all maintenance to maximize uptime
D) Perform maintenance without tracking its impact on the error budget

 

Correct answers: A – Explanation:
Error budget management ensures maintenance fits within the 43-minute monthly allowance for 99.9% SLO. 8 hours far exceeds the budget. Avoiding maintenance leads to technical debt and larger outages. Untracked maintenance may exceed the error budget unknowingly.
