CCIE Wireless (legacy) — Question 2

When your wireless client device roams from one AP to another on the same network, which IEEE protocol can be used to authenticate the clients faster?

Answer options

• A. 802.11k also called Predictive Based Roaming.
• B. 802.11k also called Assisted Roaming.
• C. 802.11r also called Predictive Based Roaming.
• D. 802.11r also called Fast BSS Transition.
• E. 802.11k also called Fast BSS Transition.
• F. 802.11r also called Predictive Based Roaming.

Correct answer: B

Explanation

The correct answer is B, as 802.11k, known as Assisted Roaming, helps clients roam more efficiently by providing information about neighboring APs. Other options, while mentioning relevant protocols, either mislabel the correct protocol or refer to features that do not specifically enhance the roaming authentication speed.
