CV0-004 Security Practice Question
A cloud security engineer is hardening a Kubernetes cluster. Which TWO measures should be implemented to improve container security? (Choose two.)
⚠ Common exam trap
A common misconception is that ConfigMaps are a secure place for secrets, but ConfigMaps lack encryption and access control features, making them unsuitable for sensitive data.
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
✓
Implement runtime security monitoring
A is correct because runtime security monitoring (e.g., using Falco, Sysdig, or Aqua Security) detects and alerts on anomalous behavior within running containers, such as unexpected system calls, privilege escalations, or file system changes. This is a critical layer of defense that complements image scanning by catching threats that bypass static checks, such as zero-day exploits or compromised containers. Without runtime monitoring, malicious activity inside a container can go undetected until significant damage occurs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement runtime security monitoring
Why this is correct
Runtime security detects suspicious container behavior.
- ✗
Store secrets in ConfigMaps
Why it's wrong here
Secrets should be stored in dedicated secrets management, not ConfigMaps.
- ✗
Disable audit logging to reduce overhead
Why it's wrong here
Disabling audit logging reduces visibility, not improve security.
- ✗
Use default service accounts for all pods
Why it's wrong here
Default service accounts may have excessive permissions.
- ✓
Enable image scanning for vulnerabilities
Why this is correct
Image scanning detects known vulnerabilities in base images.
