Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set up a Binary Authorization policy that requires attestation.
Why this is correct
This is the core policy to require signed images.
- ✓
Create an attestation note and attestor in Binary Authorization.
Why this is correct
The attestor defines the signing authority.
- ✗
Configure an Artifact Registry repository with a vulnerability scanning policy.
Why it's wrong here
Vulnerability scanning is separate from Binary Authorization.
- ✓
Add a constraint to the GKE cluster's Binary Authorization policy that restricts the allowed registry to the specific Artifact Registry repository.
Why this is correct
This ensures only images from that registry are allowed.
- ✗
Create a Cloud KMS key and an attestor in the same project as the repository.
Why it's wrong here
Attestor and key can be in different projects; not necessarily same project as repository.
