- A
Using hostPath mounts with read-only access
Why wrong: Read-only hostPath mounts are less severe than privileged containers.
- B
Using ConfigMaps for non-sensitive data
Why wrong: This is acceptable; sensitive data should use Secrets.
- C
Privileged containers with unrestricted host access
Privileged containers can escape to the host, leading to full compromise.
- D
Running containers as non-root user
Why wrong: This is a security best practice, not a misconfiguration.

CS0-003 Vulnerability Management Practice Question
This CS0-003 practice question tests your understanding of vulnerability management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 security analyst is reviewing a Kubernetes cluster configuration. Which of the following misconfigurations poses the MOST severe security risk?
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
✓
Privileged containers with unrestricted host access
Privileged containers bypass all security restrictions and can access the host system, posing the most severe risk.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using hostPath mounts with read-only access
Why it's wrong here
Read-only hostPath mounts are less severe than privileged containers.
- ✗
Using ConfigMaps for non-sensitive data
Why it's wrong here
This is acceptable; sensitive data should use Secrets.
- ✓
Privileged containers with unrestricted host access
Why this is correct
Privileged containers can escape to the host, leading to full compromise.
Related concept
Authentication checks who the user is.
- ✗
Running containers as non-root user
Why it's wrong here
This is a security best practice, not a misconfiguration.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related CS0-003 questions on access control and AAA configuration.
