Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 19

A wireless engineer is designing a wireless network to support real time applications over wireless. Which IEEE protocol must the engineer enable on the WLC so that the number of packets that are exchanged between an access point and client are reduced and fast roaming occurs?

Answer options

Correct answer: B

Explanation

The correct answer is 802.11r, which is designed specifically to support fast roaming by enabling quicker handoffs between access points. The other options, while relevant to security and network management, do not directly address the reduction of packet exchanges or facilitate the fast roaming necessary for real-time applications.
