CompTIA Network+ (N10-009) — Question 49

A technician is troubleshooting wireless connectivity near a break room. Whenever a user turns on the microwave, connectivity to the user's laptop is lost. Which of the following frequency bands is the laptop most likely using?

Answer options

• A. 2.4GHz
• B. 5GHz
• C. 6GHz
• D. 900MHz

Correct answer: A

Explanation

The correct answer is A, 2.4GHz, because microwaves operate on a similar frequency and can cause interference with devices using this band. The other options, such as 5GHz and 6GHz, are less susceptible to such interference, while 900MHz is not commonly used for modern wireless connections.
