A network technician is configuring a wireless network. To avoid interference from other wireless networks in the area, the technician should change which setting?
The correct answer is A. Channel. Changing the wireless channel moves the access point to a different frequency range, reducing co-channel and adjacent-channel interference from neighboring wireless networks.

Why each option
Changing the wireless channel moves the access point to a different frequency range, reducing co-channel and adjacent-channel interference from neighboring wireless networks.
In the 2.4 GHz band, only channels 1, 6, and 11 are non-overlapping. If nearby networks use the same channel, interference degrades performance. Switching to a less congested channel ensures the AP operates on a different frequency from neighboring networks, eliminating or reducing interference.
The SSID is the network name and is a logical identifier; changing it has no effect on radio frequency interference between networks.
Firewall rules control which traffic is permitted or denied on the network and have no impact on wireless RF channel interference.
Encryption (WPA2, WPA3) secures data in transit but does not change the radio frequency used, so it does not reduce RF interference.
