CompTIA A+ Core 1 (220-1101) — Question 538

Which of the following combinations of specifications and frequencies delivers the greatest speed and compatibility for IoT devices?

Answer options

• A. A and 5GHz
• B. В and 2.4GHz
• C. G and 5GHz
• D. N and 2.4GHz

Correct answer: D

Explanation

Option D is correct because the N specification at 2.4GHz offers a good balance of range and speed, which is beneficial for IoT devices. Options A and C, while using 5GHz, may have reduced range, making them less suitable for many IoT applications. Option B uses В, which is not optimized for the performance needed for IoT devices.
