A client engages a penetration testing firm to evaluate the security of their internal network. During the scoping meeting, the client states that they use a network access control (NAC) solution that might block the tester's machine if it is connected to the internal network without prior authorization. Which of the following should be included in the rules of engagement to address this potential issue?

A client engages a penetration testing firm to evaluate the security of their internal network. During the scoping meeting, the client states that they use a network access control (NAC) solution that might block the tester's machine if it is connected to the internal network without prior authorization. Which of the following should be included in the rules of engagement to address this potential issue?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

Include a requirement that the client disables NAC during the testing window.

Disabling NAC globally would change the security posture and potentially allow other unauthorized devices onto the network, which is not a reasonable request.

B

Distractor review

State that the tester will not connect to the internal network and will only test externally.

The client requested an internal network test; testing externally would not fulfill the project scope.

C

Distractor review

Specify that the tester will bypass NAC as part of the test objectives.

Bypassing NAC could be a test goal, but the immediate operational issue is that the tester's device may be blocked. The ROE should address access, not add an unexpected objective.

D

Best answer

Add a clause requiring the client to whitelist the tester's MAC address in the NAC policy before testing.

Whitelisting the tester's MAC address allows the NAC to recognize the testing device as authorized, preventing service disruption without weakening overall security.

Common exam trap

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.

Technical deep dive

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.

FAQ

Questions learners often ask

What does this PT0-002 question test?

Authentication checks who the user is.

What is the correct answer to this question?

The correct answer is: Add a clause requiring the client to whitelist the tester's MAC address in the NAC policy before testing. — NAC solutions can automatically block unknown devices. To prevent the tester's machine from being blocked, the best approach is to have the client whitelist the tester's MAC address or IP address in the NAC solution before testing begins. This ensures that the tester's activities are not disrupted and that the test can proceed smoothly. Not using the internal network would defeat the purpose of an internal test. The tester should not propose bypassing NAC as a goal of the test (that would be a scope creep), and asking the client to disable NAC globally would be overly disruptive and unrealistic.
