- A
Apply Pod Security Standards (e.g., restricted policy)
Pod Security Standards enforce security contexts that limit pod capabilities.
- B
Implement Kubernetes RBAC to restrict permissions to namespaces and resources
RBAC enforces least privilege by granting only needed permissions.
- C
Implement network policies to restrict pod-to-pod communication
Why wrong: Network policies control traffic, not permissions or privileges.
- D
Create service accounts with only the necessary permissions for each application
Service accounts should have minimal permissions to follow least privilege.
- E
Use namespaces to separate environments
Why wrong: Namespaces provide isolation but do not enforce least privilege for users/pods.

CV0-004 Security Practice Question
This CV0-004 practice question tests your understanding of security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
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.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"least"Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.

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.
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
Cisco 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.
Detailed technical explanation
How to think about this question
Kubernetes RBAC uses Role and ClusterRole objects with verbs (get, list, create) on resources (pods, secrets) to enforce least privilege; service accounts bind to these roles via RoleBindings, ensuring each application only has permissions for its namespace and resources. Pod Security Standards are implemented via admission controllers (e.g., PodSecurity admission plugin) that evaluate pods against policies like 'restricted' at creation time, rejecting those that violate constraints such as 'allowPrivilegeEscalation: false' or 'readOnlyRootFilesystem: true'.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
