Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Kube-bench
Why it's wrong here
Incorrect; Kube-bench checks Kubernetes CIS benchmarks.
- ✗
Clair
Why it's wrong here
Incorrect; Clair is a vulnerability scanner.
- ✓
Cosign
Why this is correct
Correct; Cosign is used for image signing and verification.
- ✗
Trivy
Why it's wrong here
Trivy is a vulnerability scanner for container images and infrastructure-as-code, not a signing tool; it cannot generate or verify cryptographic signatures to attest to image provenance, which is the core requirement for integrity in the supply chain. It is tempting because Trivy is widely used in container security pipelines for scanning known vulnerabilities (CVEs) and misconfigurations, making it the correct choice when the task is to identify security flaws in images rather than to sign them.
