CV0-004 Security Practice Question
A security team discovers that a container image used in production contains a known vulnerability in one of its base image layers. Which action should be taken to remediate this issue?
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 container image using an updated base image
The vulnerability is in the base image, so rebuilding the image using an updated base image that includes the security fix is the correct remediation. Additionally, scanning images in a CI/CD pipeline can catch vulnerabilities before deployment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Rebuild the container image using an updated base image
Why this is correct
Rebuilding with a patched base image resolves the vulnerability at the image level.
- ✗
Delete the container and recreate it from the same image
Why it's wrong here
Recreating from the same image will still have the vulnerability.
- ✗
Apply a security patch to the running container
Why it's wrong here
Containers are immutable; patches should be applied to the image, not the running container.
- ✗
Enable runtime security monitoring to detect exploitation attempts
Why it's wrong here
Monitoring does not fix the existing vulnerability.
