Google Cloud Professional DevOps Engineer Practice Exam: Test Your Knowledge 2025

Your organization is setting up a new Google Cloud environment and needs to enforce that all projects must be created under specific folders based on department. You want to prevent users from creating projects directly under the organization node. What is the most effective way to achieve this?

You are implementing a CI/CD pipeline using Cloud Build for a microservices application. The build process requires access to secrets stored in Secret Manager. Following security best practices, how should you grant Cloud Build access to these secrets?

Your SRE team needs to define an SLO for a customer-facing API. The business requirement is that 99.5% of requests must complete within 300ms over a 30-day window. Which Google Cloud service should you use to implement and monitor this SLO effectively?

You need to implement monitoring for a GKE cluster running multiple microservices. You want to collect custom application metrics, system metrics, and correlate them with distributed traces. What combination of tools should you use?

Your application deployed on Cloud Run is experiencing high latency during traffic spikes. Analysis shows that cold start times are the primary issue. What is the most cost-effective solution to reduce this latency?

Your company is adopting Infrastructure as Code using Terraform for Google Cloud resources. You need to manage Terraform state files securely for multiple teams working on different projects. What is the recommended approach?

You are implementing a blue-green deployment strategy for a stateless application on GKE. The deployment must allow instant rollback and zero downtime. Traffic should be switched only after health checks pass on the new version. What is the best implementation approach?

Your application's error budget for the month has been exhausted with one week remaining. According to SRE principles, what should be the immediate course of action?

You need to set up alerting for your application that sends notifications when request latency exceeds thresholds. The alert should only trigger if the condition persists for 5 minutes to avoid false positives from brief spikes. How should you configure this in Cloud Monitoring?

Your Cloud SQL database is experiencing performance degradation during business hours. Query insights show that several queries are scanning large tables. What immediate optimization should you implement?

You are designing a CI/CD pipeline that must deploy to multiple environments (dev, staging, production) with different configurations. The pipeline should enforce that production deployments require manual approval and pass all tests. What is the most appropriate design pattern?

During a postmortem analysis of a service outage, your team identified that cascading failures occurred when a dependency became unavailable. What SRE pattern should you implement to prevent similar incidents?

Your organization needs to implement a tag-based resource hierarchy to track costs by team and environment. Multiple teams will deploy resources across several projects. What is the most effective way to enforce consistent tagging?

You need to implement distributed tracing for a microservices application running on GKE to identify latency bottlenecks across service calls. The application is written in multiple languages. What approach should you take?

Your application on GKE is experiencing intermittent performance issues. You need to identify which pods are consuming excessive CPU and memory over time. What is the most effective approach?

Your team is implementing a canary deployment for a critical production service. You want to route 5% of traffic to the canary version and automatically roll back if error rates exceed acceptable thresholds. What is the recommended implementation on GKE?

Your SRE team needs to reduce toil related to manual scaling of Compute Engine instances based on application load. The application has predictable daily traffic patterns but occasional unexpected spikes. What is the best approach?

You are experiencing slow response times from your application that uses Cloud Storage for serving user-uploaded images. Users are globally distributed. What optimization would provide the most improvement?

Your organization is implementing policy-as-code for cloud infrastructure. You need to prevent developers from creating resources in non-approved regions while using Terraform. What is the most effective preventive control?

You need to implement a deployment pipeline that performs automated security scanning of container images before they are deployed to production GKE clusters. What services should you integrate into your pipeline?
