Cloud Deploy and Cloud Run
Why wrong: Cloud Deploy orchestrates deployments, Cloud Run runs containers, but they don't enforce signing/scanning.
- B
Cloud Build and Artifact Registry
Why wrong: Cloud Build builds images, Artifact Registry stores them, but neither enforces deployment policies.
- C
Binary Authorization and Container Scanning API
Binary Authorization enforces signing; Container Analysis provides vulnerability scanning.
- D

PCDE Practice Question: Building and Implementing CI/CD Pipelines for a Service
This PCDE practice question tests your understanding of building and implementing ci/cd pipelines for a service. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An organization uses Artifact Registry to store Docker images. They want to enforce that only images that have passed vulnerability scanning and are signed can be deployed to GKE. Which two services should they use together?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Binary Authorization and Container Scanning API
Binary Authorization enforces that only signed and verified container images can be deployed to GKE, while the Container Scanning API (now part of Artifact Analysis) performs vulnerability scanning on images stored in Artifact Registry. Together, they ensure that only images that have passed vulnerability scanning and are cryptographically signed can be deployed, meeting the organization's requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google often tests the distinction between services that perform an action (like scanning or signing) versus services that enforce a policy based on that action, so candidates mistakenly pick Cloud Build and Artifact Registry (Option B) because they handle scanning and storage, but they lack the enforcement mechanism that Binary Authorization provides.
Detailed technical explanation
How to think about this question
Binary Authorization uses attestors (e.g., Cloud KMS or PGP keys) to verify that an image has a valid cryptographic signature before allowing deployment, and it integrates with Container Analysis (which includes the Container Scanning API) to check for vulnerabilities. Under the hood, Binary Authorization evaluates admission webhook requests against a policy that requires both a valid attestation and a passing vulnerability scan, blocking any image that fails either check. In a real-world scenario, a CI/CD pipeline can use Cloud Build to sign images after scanning, and Binary Authorization ensures that even if a malicious actor pushes an unsigned image to Artifact Registry, it cannot be deployed to GKE.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
