CompTIA Network+ (N10-007) — Question 429

A network technician is assisting a user who cannot connect to a wireless connection. The user is connecting to the correct SSID and has the correct pre-shared key. The technician verifies the WAP is working, and other clients are connected to it from the same location. Which of the following should the technician investigate?

Answer options

• A. Channel overlap
• B. Wireless frequency
• C. AP power levels
• D. Encryption type

Correct answer: D

Explanation

The technician should investigate the encryption type because even with the correct SSID and pre-shared key, if the encryption type on the user's device does not match that of the access point, the connection will fail. The other options, while potentially relevant, do not directly address the issue of authentication to the network.
