CompTIA Network+ (N10-008) — Question 720

A network technician for a bank configured a WLAN that provides good coverage. Bank employees are now reporting Wi-Fi issues when the microwave in the lunch room area is used. Which of the following frequencies should the technician use to minimize interference?

Answer options

• A. 2.4GHz
• B. 5MHz
• C. 5GHz
• D. 700MHz

Correct answer: C

Explanation

The 5GHz frequency is less susceptible to interference from microwaves, which commonly operate on the 2.4GHz band. The other options, including 2.4GHz, are more likely to experience interference due to their proximity to the microwave frequency, while 5MHz and 700MHz are not typically used for Wi-Fi networks.
