Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
A team wants to enforce that only container images signed by their CI/CD system can be deployed to GKE. They have enabled Binary Authorization with a policy that requires an attestor. What additional step must they take to bind the attestor to the image signing process?
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
✓
Create a Container Analysis note and grant the attestor service account the containeranalysis.notes.attacher role
After creating the attestor, you must create an AttestationAuthority note in Container Analysis and grant the attestor service account permission to bind attestations. Configuring Cloud Build to sign images is part of the process but not the binding step.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a Container Analysis note and grant the attestor service account the containeranalysis.notes.attacher role
Why this is correct
This binds the attestor to the Container Analysis note, allowing it to create attestations for signed images.
- ✗
Add the attestor to the Binary Authorization policy as a required attestor
Why it's wrong here
That is done in the policy, but the binding between attestor and image requires a Container Analysis note.
- ✗
Create a Cloud Build step that signs the image and stores the signature in Cloud Storage
Why it's wrong here
Signing is separate from binding; the binding step is about the attestor's relationship to the note.
- ✗
Configure the GKE cluster to require Binary Authorization with the --no-enforce flag
Why it's wrong here
The flag --no-enforce disables enforcement, which is opposite to the requirement.
