CompTIA ITF+ (FC0-U61) — Question 229

A technician needs to install and configure a wireless SOHO network. Which of the following should the technician configure to reduce Wi-Fi interference from other household appliances?

Answer options

• A. 2.4GHz
• B. 5GHz
• C. 802.11b
• D. 802.11g

Correct answer: B

Explanation

Choosing the 5GHz frequency band (option B) helps reduce Wi-Fi interference as it is less crowded compared to the 2.4GHz band, which is commonly used by many household appliances. Options A, C, and D either refer to the more congested 2.4GHz band or older standards, which are more susceptible to interference.
