Quick Answer
Cloud Build is the correct choice for orchestrating a CI/CD pipeline that builds container images, runs unit tests, and deploys to Google Kubernetes Engine (GKE). As a fully managed CI/CD platform, Cloud Build executes a series of steps defined in a cloudbuild.yaml file, where each step—such as building a Docker image or running tests—must succeed before the pipeline proceeds to the next stage. This sequential, failure-stopping behavior ensures that deployments to GKE only happen after all tests pass, making it the ideal single-service orchestrator for this workflow. On the Google Professional Cloud Developer exam, this question tests your understanding of how Cloud Build integrates natively with Container Registry and GKE, often contrasting it with services like Cloud Deploy (which focuses on delivery, not build) or Cloud Run (which targets serverless). A common trap is choosing Cloud Deploy for its release management features, but remember: Cloud Build handles the entire build-test-deploy lifecycle in one pipeline. Memory tip: “Build tests, then deploy—Cloud Build is the one-stop CI/CD key.”
This PCD practice question tests your understanding of building and testing applications. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer is building a CI/CD pipeline for a microservices application. The pipeline should build a container image, run unit tests, and deploy to Google Kubernetes Engine (GKE) only if all tests pass. Which Google Cloud service is best suited for orchestrating this pipeline?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Cloud Build
Cloud Build is the native CI/CD service for building, testing, and deploying on Google Cloud.
Compute Engine
Why wrong: Compute Engine provides virtual machines, not pipeline orchestration.
Cloud Run
Why wrong: Cloud Run is a compute platform for running containers, not a CI/CD pipeline service.
Cloud Functions
Why wrong: Cloud Functions is for event-driven compute, not for CI/CD pipelines.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cloud Build
Cloud Build is the correct choice because it is a fully managed CI/CD platform that natively supports building container images, running unit tests, and deploying to GKE. It can be configured with a cloudbuild.yaml file to define steps for building, testing, and deploying, and it only proceeds to the deploy step if all prior steps (including tests) succeed. This makes it the best fit for orchestrating the entire pipeline in a single, integrated service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Compute Engine
Why it's wrong here
Compute Engine provides virtual machines, not pipeline orchestration.
Cloud Run
Why it's wrong here
Cloud Run is a compute platform for running containers, not a CI/CD pipeline service.
Cloud Functions
Why it's wrong here
Cloud Functions is for event-driven compute, not for CI/CD pipelines.
Common exam traps
The trap here is that candidates may confuse Cloud Run (a deployment target) with a CI/CD orchestrator, or assume Compute Engine is needed for custom CI/CD tools, but Cloud Build is the native, fully managed service for this exact pipeline workflow.
Detailed technical explanation
Cloud Build uses a build configuration file (cloudbuild.yaml) where each step runs in a Docker container, allowing you to specify custom test images or use community builders. It integrates with Container Registry or Artifact Registry for image storage and can trigger deployments via kubectl or the GKE deploy step. A subtle behavior is that Cloud Build automatically fails the pipeline if any step returns a non-zero exit code, ensuring tests must pass before deployment.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
