Computer Hacking Forensic Investigator (CHFI v10) — Question 606

When setting up a wireless network with multiple access points, why is it important to set each access point on a different channel?

Answer options

• A. Multiple access points can be set up on the same channel without any issues
• B. Avoid over-saturation of wireless signals
• C. So that the access points will work on different frequencies
• D. Avoid cross talk

Correct answer: D

Explanation

Setting each access point on a different channel helps prevent cross talk, which can degrade network performance and reliability. While it is technically possible to use the same channel for multiple access points, doing so can lead to interference and decreased signal quality. Therefore, using different channels is essential for maintaining optimal wireless communication.
