GCP Professional Cloud Architect Practice Question

Your team maintains a Java microservice that publishes to and consumes from Cloud Pub/Sub using the official Java client libraries. You need to introduce unit tests that will run inside your Cloud Build CI pipeline and must meet these constraints:

  • Execute quickly with no outbound network connectivity
  • Avoid all Google Cloud charges
  • Require no changes to the production code path that constructs the Pub/Sub client

Which approach best satisfies these requirements?

  • Replace the Pub/Sub client with Mockito stubs that instantly acknowledge publish and pull operations.

  • Start the Cloud Pub/Sub emulator in the CI job and, in test setup code, build Pub/Sub clients whose endpoint is set to the emulator's localhost address.

  • Run the tests against a dedicated Cloud Pub/Sub instance in a separate project and delete topics and subscriptions after each build.

  • Create a single-node GKE cluster during the build and access managed Cloud Pub/Sub through Private Google Access.
