- A
A Binary Authorization attestor configured to verify the attestation key
The attestor holds the public key to verify attestations.
- B
A Cloud Build step that creates a signed attestation using KMS
The build step signs the image and pushes the attestation to Container Analysis.
- C
A Cloud Deploy delivery pipeline with a canary strategy
Why wrong: Binary Authorization does not require Cloud Deploy.
- D
An Artifact Registry repository configured with vulnerability scanning
Why wrong: Vulnerability scanning is separate from Binary Authorization.
- E
A Binary Authorization policy that requires at least one attestation
The policy enforces that images must have a valid 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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 team uses Cloud Build to build and push Docker images to Artifact Registry. They need to ensure that only images built from the main branch and signed by a trusted key can be deployed to GKE using Binary Authorization. Which THREE components must be in place?
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
✓
A Binary Authorization attestor configured to verify the attestation key
Option A is correct because a Binary Authorization attestor is the component that defines the trusted key(s) used to verify that an image has been signed. Without an attestor configured with the correct public key, Binary Authorization cannot validate the attestation signature, and the policy cannot enforce that only signed images are deployed.
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
Cisco often tests the misconception that vulnerability scanning or deployment strategies are part of Binary Authorization enforcement, when in fact only attestors, signed attestations, and a policy requiring attestations are the mandatory components.
Detailed technical explanation
How to think about this question
Binary Authorization uses a policy that requires one or more attestations, each verified by an attestor bound to a specific cryptographic key pair (typically stored in Cloud KMS). The attestation is a signed payload (e.g., a DSSE envelope) containing the image digest; the attestor's public key is used to verify the signature at deploy time. This ensures that only images signed by an authorized key—such as one used in a Cloud Build step—can be deployed, even if the image exists in the registry.
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.
