Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Kubernetes pod security policies
Why it's wrong here
Pod security policies restrict runtime behavior, not image vulnerabilities.
- ✗
Use only official images from Docker Hub
Why it's wrong here
Official images may still have vulnerabilities.
- ✓
Perform container image scanning during CI/CD
Why this is correct
Scanning identifies vulnerabilities early in the pipeline.
