CompTIA ITF+ (FC0-U61) — Question 220

Joe, a tech-savvy teenager, has received one of the best new home Wi-Fi routers on the market. Joe’s parents have entrusted Joe to set up the router. To leverage the best throughput options available for Joe’s devices, the router is located in Joe’s bedroom. Joe’s parents’ devices are set to slower standards. Which of the following is being used for Joe’s devices?

Answer options

• A. 802.11n 2.4GHz
• B. 802.11ac 2.4GHz
• C. 802.11n 5GHz
• D. 802.11ac 5GHz

Correct answer: D

Explanation

The correct answer is D, 802.11ac 5GHz, as it provides higher throughput and is suitable for modern, high-performance devices. Options A and C utilize the 802.11n standard, which offers slower speeds compared to 802.11ac. Option B, while still 802.11ac, operates on the 2.4GHz band, which is typically slower than the 5GHz band used in option D.
