Question 360
A release pipeline deploys images from a public registry directly into production GKE without checking the builder identity or signed provenance. Which limitation must be considered before claiming the issue is fully resolved?
Explanation
Correct Answer
An image signature does not prove all dependencies are free of vulnerabilities. This caution prevents extrapolating beyond the specific evidence or product boundary. Admission controls verify release provenance and policy before execution. The unresolved point should be tested using build provenance attestations, artifact digests and cluster admission logs rather than assuming a working interface proves full compliance or resilience.
Incorrect Answers
Signed provenance is a guarantee that every library is vulnerability-free. This limitation is framed as a blanket exception, but the case requires a different, narrower caution. The relevant boundary is that an image signature does not prove all dependencies are free of vulnerabilities. Admission controls verify release provenance and policy before execution. Inspect build provenance attestations, artifact digests and cluster admission logs.
Signed supply-chain attestation guarantees absence of runtime misconfiguration. The proposed claim mistakes an incomplete signal or product feature for a universal guarantee. The relevant boundary is that an image signature does not prove all dependencies are free of vulnerabilities. Admission controls verify release provenance and policy before execution. Inspect build provenance attestations, artifact digests and cluster admission logs.
Image signing by itself establishes that every running pod has correct IAM. This claim exceeds the evidence and ignores an important risk or operational dependency. The relevant boundary is that an image signature does not prove all dependencies are free of vulnerabilities. Admission controls verify release provenance and policy before execution. Inspect build provenance attestations, artifact digests and cluster admission logs.
