- A
Configure Artifact Registry to automatically sign images on push
Why wrong: Artifact Registry does not automatically sign images.
- B
Use Cloud Deploy's canary deployment with audit logging to verify image provenance
Why wrong: Audit logs do not enforce image signing.
- C
Enable Binary Authorization on the GKE cluster and configure the admission controller to use Cloud Key Management Service
Why wrong: Signing must happen during build, not just admission controller configuration.
- D
In Cloud Build, use the `gcloud beta artifacts docker images sign` command after building the image, and set the Binary Authorization policy to require attestations from that signer
Correct: signing occurs in the pipeline, and policy requires attestation.

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. 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 company is implementing Binary Authorization with Cloud Deploy. They want to ensure that only images signed by the CI system (using Cloud Build) are deployed to production. What must be configured?
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
✓
In Cloud Build, use the `gcloud beta artifacts docker images sign` command after building the image, and set the Binary Authorization policy to require attestations from that signer
Option D is correct because it describes the exact workflow: Cloud Build signs the container image using the `gcloud beta artifacts docker images sign` command, which creates a cryptographic attestation stored in Cloud Key Management Service (KMS). The Binary Authorization policy is then configured to require an attestation from that specific signer (the CI system's KMS key), ensuring only images signed by the CI pipeline can be deployed to production.
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
The trap here is that candidates assume enabling Binary Authorization alone is sufficient, but they overlook the critical requirement to both sign the image and configure the policy to require attestations from that specific signer.
Detailed technical explanation
How to think about this question
Binary Authorization uses a policy that defines attestors, which are references to public keys stored in Cloud KMS. When an image is signed, a signed attestation (a JSON payload containing the image digest) is created and stored in Artifact Registry or a separate attestation store. The admission controller on GKE verifies the attestation against the policy before allowing the pod to run; if the attestation is missing or invalid, the deployment is rejected. This ensures that only images that have passed through the CI pipeline's signing step are deployed to production.
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.
