CompTIA Network+ (N10-008) — Question 686

A user returns to the office after working remotely for an extended period. The user is reporting limited access to the office wireless network and the inability to reach company resources on the network. The user connected to the guest network, ensured all patches were applied, and checked to make sure software was up to date. Which of the following is most likely the cause of the issue?

Answer options

• A. The laptop drivers need to be updated to support a new wireless infrastructure.
• B. The wireless passphrase has been cycled and needs to be updated.
• C. The NAC appliance has labeled the laptop as non-complaint.
• D. The WAP transmit power is too low and cannot complete user authentication.

Correct answer: C

Explanation

The correct answer is C because the NAC (Network Access Control) appliance can restrict access to devices that do not meet specific compliance standards. The other options, while plausible, do not directly address the compliance aspect that the NAC appliance enforces.
