CompTIA Network+ (N10-007) — Question 638

A technician is dispatched to replace an access point that has failed. The device is preconfigured with the correct SSID and passphrase. When the user tries to connect to the SSID, the connection fails. Which of the following is the MOST likely cause of the issue?

Answer options

• A. Interference
• B. Channel overlap
• C. Distance limitations
• D. Security type mismatch

Correct answer: D

Explanation

The most likely reason for the connection failure is a security type mismatch, as the user may be trying to connect with a different security protocol than what the access point is configured for. The other options, such as interference, channel overlap, and distance limitations, could cause connectivity issues, but they are less specific to the situation where the SSID and passphrase are already correct.
