- A
Use kubectl delete pod to remove the running container
Why wrong: Deleting the pod does not fix the underlying image vulnerability.
- B
Delete the image from the registry
Why wrong: Deleting the image does not prevent it from being used if it is already pulled.
- C
Rebuild the image with updated base images and re-deploy
Rebuilding with patched base images resolves the vulnerabilities.
- D
Ignore the CVEs because the image is running in a non-production environment
Why wrong: Critical CVEs should be addressed regardless of environment.
Question 315 of 997
Best Action After Trivy Reports Critical CVEs
This CKS practice question tests your understanding of supply chain security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You run 'trivy image myapp:latest' and the scan reports several critical CVEs. What is the best action to take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.

"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
✓
Rebuild the image with updated base images and re-deploy
Option C is correct because rebuilding the image with updated base images directly addresses the root cause of the CVEs—outdated or vulnerable packages in the container image. After rebuilding, you must re-deploy the updated image to replace the running vulnerable containers. This aligns with the supply chain security principle of maintaining a secure software bill of materials (SBOM) and ensuring images are patched against known vulnerabilities before deployment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
A common misconception is that deleting the pod or image is sufficient remediation, when the correct action is to patch the image at the source and re-deploy to eliminate the vulnerability from the running environment.
Detailed technical explanation
How to think about this question
Trivy scans the image layers and compares installed package versions against vulnerability databases (e.g., NVD, Red Hat OVAL). A rebuild with updated base images (e.g., using `apt-get update && apt-get upgrade` or pulling a newer base tag) ensures the packages are patched to versions not listed in the CVE database. In a real-world scenario, you would also implement image signing (e.g., with Cosign) and enforce admission controls (e.g., Kyverno or OPA Gatekeeper) to prevent deployment of images with critical CVEs.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CKS exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
