CV0-004 Security Practice Question
A company is deploying a cloud-native application that uses containers orchestrated by Kubernetes. The security team wants to enforce the principle of least privilege at the Kubernetes level. Which THREE measures should be implemented? (Choose three.)
⚠ Common exam trap
The CV0-004 exam often tests the distinction between network-level controls (network policies) and identity/privilege controls (RBAC, Pod Security Standards), leading candidates to mistakenly select network policies as a least-privilege measure when they only restrict traffic, not permissions.
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
✓
Apply Pod Security Standards (e.g., restricted policy)
Pod Security Standards (PSS) define security contexts for pods, with the 'restricted' policy enforcing the principle of least privilege by disallowing privileged containers, host network access, and other high-risk capabilities. This directly prevents pods from running with unnecessary permissions, aligning with the security team's goal at the pod level.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Apply Pod Security Standards (e.g., restricted policy)
Why this is correct
Pod Security Standards enforce security contexts that limit pod capabilities.
- ✓
Implement Kubernetes RBAC to restrict permissions to namespaces and resources
Why this is correct
RBAC enforces least privilege by granting only needed permissions.
- ✗
Implement network policies to restrict pod-to-pod communication
Why it's wrong here
Network policies control traffic, not permissions or privileges.
- ✓
Create service accounts with only the necessary permissions for each application
Why this is correct
Service accounts should have minimal permissions to follow least privilege.
- ✗
Use namespaces to separate environments
Why it's wrong here
Namespaces provide isolation but do not enforce least privilege for users/pods.
