20+ practice questions focused on Building and Implementing CI/CD Pipelines for a Service — one of the most tested topics on the Google Professional Cloud Database Engineer exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Building and Implementing CI/CD Pipelines for a Service PracticeA DevOps engineer wants to build a CI/CD pipeline that automatically builds and tests code every time a developer pushes a new branch to a Git repository. Which Cloud Build trigger type should they use?
Explanation: Option C is correct because a 'Push to any branch' trigger in Cloud Build automatically initiates a build whenever a developer pushes code to any branch in the repository. This matches the requirement to build and test code on every new branch push, without manual intervention or branch-specific filters.
A team uses Cloud Build to build a Docker image and push it to Artifact Registry. They need to cache Docker layers to speed up subsequent builds. The build runs on a private pool with access to a VPC. Which caching approach should they implement in cloudbuild.yaml?
Explanation: Kaniko layer caching with a cache repository in Artifact Registry is the recommended method for Cloud Build. It stores intermediate layers and reuses them when unchanged. Docker cache import/export requires a persistent volume, which is not native to Cloud Build.
An engineer configures Cloud Deploy to promote a container to production after manual approval. The deployment strategy must gradually shift traffic from the current version to the new version while monitoring error rates. Which deployment strategy should they select in the delivery pipeline?
Explanation: Canary deployment is the correct choice because it gradually shifts traffic from the current version to the new version while allowing monitoring of error rates. In Cloud Deploy, a canary strategy uses a sequence of phases (e.g., 10%, 50%, 100%) to incrementally route traffic, enabling real-time observability and automated rollback if error thresholds are breached.
A company uses Cloud Build to deploy to Cloud Run. They need to test a new revision with a specific tag without serving any live traffic. After validation, they want to shift 10% of traffic to the new revision. Which two gcloud commands should they use?
Explanation: Option A is correct because the `--no-traffic` flag deploys the new revision without routing any live traffic to it, while `--tag=test` assigns a specific tag (e.g., 'test') that allows direct URL-based validation. The second command `gcloud run services update-traffic --to-revisions=test=10` then shifts exactly 10% of traffic to that tagged revision, enabling a gradual rollout. This two-step approach ensures the revision is validated before receiving production traffic.
A team wants to adopt GitOps for a GKE cluster. They need a solution that automatically syncs their Kubernetes manifests from a Git repository to the cluster and ensures the cluster state matches the repo. Which Google Cloud service should they use?
Explanation: Config Sync is the correct choice because it is the native GitOps agent within Google Cloud's Anthos platform, designed specifically to continuously reconcile the state of a GKE cluster with Kubernetes manifests stored in a Git repository. It automatically detects changes in the configured source of truth and applies them to the cluster, ensuring drift is corrected without manual intervention.
