Cloud DevOps Engineer Practice Exam 2025: Latest Questions

Your organization is setting up a new Google Cloud environment and needs to establish a hierarchy that supports multiple development teams working on different projects while maintaining centralized billing and policy control. What organizational structure should you implement?

You are implementing a CI/CD pipeline using Cloud Build for a microservices application. The build process needs to create Docker images, run unit tests, and deploy to GKE only if tests pass. Which Cloud Build configuration approach should you use?

Your application running on GKE is experiencing intermittent latency spikes. You need to implement monitoring that follows SRE best practices to identify when user experience is degraded. What should you implement first?

You need to reduce costs for your Cloud Storage buckets that contain application logs. Logs must be immediately accessible for 30 days, rarely accessed between 30-90 days, and retained for compliance for 7 years but almost never accessed. What storage strategy should you implement?

Your team is deploying a new version of a critical microservice to GKE. You need to implement a deployment strategy that minimizes risk, allows for quick rollback, and validates the new version with production traffic before full rollout. Which approach should you use?

You are implementing Infrastructure as Code for your organization using Terraform. Multiple teams need to manage infrastructure in different projects, but you need to prevent state file conflicts and ensure secure state management. What solution should you implement?

Your application on GKE has an SLO of 99.9% availability. You've consumed 70% of your error budget in the first week of the month due to a buggy release. Following SRE principles, what should your team do?

You need to implement a monitoring solution for a distributed application running across multiple GKE clusters in different regions. The solution must provide distributed tracing, correlate logs with traces, and analyze application performance. Which combination of Google Cloud services should you use?

Your organization runs a legacy application that requires specific VM configurations and manual configuration steps after VM creation. You need to implement a repeatable, version-controlled provisioning process that can be integrated into your CI/CD pipeline and supports gradual rollout of configuration changes. What solution should you implement?

Your company's microservices application experiences varying load throughout the day, with peak traffic 10x higher than baseline. You need to optimize costs while maintaining performance during peak hours. The application consists of stateless services on GKE, a Cloud SQL database, and uses Cloud Storage. The database shows high CPU during peaks but is underutilized during off-peak hours. What combination of optimizations should you implement?

Your organization is establishing a new DevOps practice and needs to define resource hierarchies for multiple development teams. Each team should have isolated environments for development, staging, and production with separate billing. What organizational structure should you implement?

You are implementing a CI/CD pipeline for a microservices application using Cloud Build. The pipeline needs to build multiple container images in parallel and only proceed to deployment if all builds succeed. Which Cloud Build feature should you use?

Your SRE team needs to define Service Level Objectives (SLOs) for a new customer-facing API. The API serves 10 million requests per day with varying importance levels. Which approach best aligns with SRE best practices?

You need to optimize costs for a Kubernetes workload running on GKE that has predictable traffic patterns with lower usage during nights and weekends. The application requires at least 10 nodes during peak hours but only 3 nodes during off-peak times. What is the most cost-effective solution?

Your team is implementing canary deployments for a service running on Cloud Run. You need to gradually shift traffic from the old revision to the new revision while monitoring error rates. If error rates exceed thresholds, traffic should automatically roll back. What implementation approach should you use?

You are establishing error budgets for your services based on SLOs. Your service has a 99.9% availability SLO for a 30-day window. After a 2-hour outage, the development team wants to know if they can proceed with a risky deployment. How should you calculate and communicate the remaining error budget?

Your organization requires all Terraform infrastructure code to be reviewed, tested, and approved before deployment to production. Multiple teams are deploying to different GCP projects. What is the best practice approach for managing Terraform state and workflows?

You are troubleshooting high latency issues in a microservices application deployed on GKE. The application consists of 15 services with complex inter-service communication patterns. Which approach will most effectively help you identify the source of latency?

Your company is running a stateful application on Compute Engine instances. You need to implement a disaster recovery strategy with a Recovery Time Objective (RTO) of 1 hour and Recovery Point Objective (RPO) of 15 minutes. The solution must be cost-effective. What should you implement?

You are designing a blue/green deployment strategy for a globally distributed application running on GKE clusters in multiple regions. The application uses Cloud SQL for its database. During the switch from blue to green, you must ensure zero downtime and the ability to quickly rollback. What is the most appropriate approach?

Your organization is bootstrapping a new Google Cloud environment and needs to establish a folder structure that supports multiple business units with independent billing but centralized security policies. Each business unit will have development, staging, and production environments. What organizational hierarchy should you implement?

You are implementing SRE practices for a microservices application. Your team wants to establish Service Level Objectives (SLOs) but is uncertain about the relationship between SLIs, SLOs, and SLAs. Which statement accurately describes these concepts?

Your application running on Google Kubernetes Engine is experiencing intermittent performance issues. You've set up Cloud Monitoring alerts, but they trigger too frequently during normal load variations. You want to reduce alert fatigue while still catching genuine performance degradation. What approach should you implement?

You need to optimize costs for a Cloud Run service that handles batch processing jobs triggered by Cloud Pub/Sub. The jobs have varying processing times from 30 seconds to 10 minutes, and the service receives sporadic traffic throughout the day. CPU usage is consistently high during job processing but idle between jobs. What configuration changes would most effectively reduce costs?

Your team is managing the lifecycle of a microservice that needs to be gradually rolled out to production. The service is deployed on GKE and you want to implement a deployment strategy that allows automatic rollback if error rates exceed 2% during the rollout. Which approach should you use?
