CompTIA Network+ (N10-007) — Question 141

A company wants to implement a wireless infrastructure on its campus to meet the needs of its BYOD initiative. The company has users with legacy devices and wants to accommodate them while delivering speed to other users who have modern systems.
Which of the following standards BEST fits these requirements?

Answer options

• A. 802.11a
• B. 802.11ac
• C. 802.11b
• D. 802.11n

Correct answer: D

Explanation

The 802.11n standard is the best choice as it supports both legacy devices and offers improved speeds for modern devices through features like MIMO and channel bonding. In contrast, 802.11a and 802.11ac primarily cater to newer devices, while 802.11b is too slow for current demands.
