- A
Use Cloud KMS to sign the image digest and store the signature in Cloud Storage.
Why wrong: Binary Authorization uses the Container Analysis API for attestations, not raw signatures in Cloud Storage.
- B
Enable the Binary Authorization API and configure a policy that requires attestations.
Why wrong: This is necessary for enforcement but does not cover signing permissions for Cloud Build.
- C
Grant the Cloud Build service account the roles/containeranalysis.notes.attacher role on the project.
This role allows Cloud Build to create attestations. Additionally, the service account needs roles/containeranalysis.occurrences.editor to attach attestations.
- D
Configure a Cloud Build step to run gcloud container binauthz attestations sign command.
Why wrong: The gcloud command for attestations is create, not sign. Also, it requires appropriate IAM permissions.
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 is implementing Binary Authorization for containers deployed to GKE. They want to enforce that only images signed by their CI pipeline can be deployed. The CI pipeline runs in Cloud Build. What must they configure to allow Cloud Build to sign images?
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
Grant the Cloud Build service account the roles/containeranalysis.notes.attacher role on the project.
Option C is correct because the Cloud Build service account needs the `roles/containeranalysis.notes.attacher` role to create attestations in Container Analysis. This role allows the service account to attach attestations to vulnerability notes, which are then used by Binary Authorization to verify that an image has been signed by the CI pipeline. Without this role, Cloud Build cannot create the attestations required for the Binary Authorization policy to enforce image signing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Cloud KMS to sign the image digest and store the signature in Cloud Storage.
Why it's wrong here

Why this is correct
This role allows Cloud Build to create attestations. Additionally, the service account needs roles/containeranalysis.occurrences.editor to attach attestations.

- ✗
Configure a Cloud Build step to run gcloud container binauthz attestations sign command.
Why it's wrong here
The gcloud command for attestations is create, not sign. Also, it requires appropriate IAM permissions.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that enabling the Binary Authorization API and configuring a policy is sufficient, but candidates overlook that the CI pipeline's service account needs explicit IAM permissions to create attestations in Container Analysis.
Trap categories for this question
Command / output trap
The gcloud command for attestations is create, not sign. Also, it requires appropriate IAM permissions.
Detailed technical explanation
How to think about this question
Binary Authorization uses attestations stored in Container Analysis, which are linked to a note (a vulnerability or generic note). The `roles/containeranalysis.notes.attacher` role allows a service account to create attestations under a specific note, which the Binary Authorization policy then checks during admission control. In practice, the CI pipeline must first sign the image digest (e.g., using Cloud KMS or a local key), then create an attestation that includes the signature and the signer's public key, and finally attach it to the note; the role is required for the attachment step.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
