CompTIA Network+ (N10-007) — Question 660

A company has moved to a building with a large number of WLANs. All clients are 802.11b/g/n capable. Which of the following can be performed to reduce the chance of interference with the nearby APs and maintain or improve the performance of the wireless clients?

Answer options

• A. Migrate the clients to 802.11a NICs.
• B. Disable 802.11n.
• C. Disable the 2.4GHz radio.
• D. Use omnidirectional antennas.

Correct answer: C

Explanation

Disabling the 2.4GHz radio will prevent interference from other devices operating in that frequency, which is common in environments with multiple WLANs. The other options either involve switching to a different standard or disabling features that could actually enhance performance, which would not effectively address interference issues.
