20+ practice questions focused on Supply Chain Security — one of the most tested topics on the Certified Kubernetes Security Specialist CKS exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Supply Chain Security PracticeWhich TWO of the following are best practices for securing the container supply chain?
Explanation: Scanning images for vulnerabilities in a CI pipeline before deployment is a best practice because it catches known CVEs early, preventing vulnerable images from reaching production. Tools like Trivy, Clair, or Grype integrate into CI/CD to enforce policy gates, ensuring only compliant images proceed.
Which THREE of the following are required to implement a secure software supply chain using Kubernetes native features?
Explanation: Option A is correct because vulnerability scanning tools like Trivy or Grype are essential for identifying known CVEs in container images before deployment. Integrating these tools into the CI/CD pipeline ensures that only images with an acceptable vulnerability posture are built and pushed to the registry, forming a foundational security gate in the software supply chain.
A DevOps team wants to ensure that only signed images from a trusted registry are deployed in the cluster. They plan to use a webhook to intercept pod creation. Which tool is best suited for this task?
Explanation: Kyverno is a Kubernetes-native policy engine that can enforce image signature verification via its `verifyImages` rule. It intercepts pod creation through a dynamic admission webhook, checking that container images are signed with a trusted key (e.g., using Sigstore/Cosign) before the pod is admitted. This directly meets the requirement to only allow signed images from a trusted registry.
A security audit reveals that a container image running in production contains a critical vulnerability (CVE-2024-1234). The image was built from a base image that had the vulnerability. What is the MOST effective long-term solution to prevent such issues?
Explanation: Option D is the most effective long-term solution because it addresses the root cause by rebuilding the image from a patched base image, eliminating the vulnerability at the source. Integrating vulnerability scanning into the CI pipeline ensures that future images are automatically checked for known CVEs before deployment, preventing vulnerable images from reaching production. This aligns with the principle of shifting security left in the software supply chain.
An organization uses a private container registry and wants to ensure that only images built from a specific CI/CD pipeline are deployed. Which combination of measures provides the strongest guarantee?
Explanation: Option E is correct because it implements a complete chain of custody for container images. In-toto generates signed attestations that record every step of the CI/CD pipeline (e.g., source code checkout, build, test), and an admission webhook like Kyverno verifies these attestations before allowing a pod to run. This ensures that only images that passed the exact, attested pipeline are deployed, providing the strongest guarantee against unauthorized or tampered images.

Practice all Supply Chain Security questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Supply Chain Security. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Supply Chain Security questions on the CKS frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Supply Chain Security is tested as part of the Certified Kubernetes Security Specialist CKS blueprint. Practicing with targeted Supply Chain Security questions ensures you can handle any format or difficulty that appears.
