Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 85

An engineer must ensure that the wireless network accomplishes fast, secure roaming by way of caching keys on the APs. Which key caching mechanism is enabled by default on a Cisco AireOS WLC?

Answer options

• A. SKC
• B. OKC
• C. 802.11r
• D. CCKM

Correct answer: B

Explanation

The correct answer is OKC (Opportunistic Key Caching), which is enabled by default on Cisco AireOS WLC to support fast roaming. SKC (Session Key Caching), 802.11r, and CCKM (Cisco Centralized Key Management) are related to roaming but are not the default caching mechanism in this context.
