Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 22

Clustering Cisco WLCs into a single RF group enables the RRM algorithms to scale beyond the capabilities of a single Cisco WLC. How many WLCs and APs in an RF group can the controller software scale up to in WLC release 8.9 depending on the platform?

Answer options

• A. up to 20 WLCs and 1000 APs
• B. up to 20 WLCs and 3000 APs
• C. up to 20 WLCs and 4000 APs
• D. up to 20 WLCs and 6000 APs

Correct answer: D

Explanation

The correct answer is D, as WLC release 8.9 supports up to 20 WLCs and 6000 APs in an RF group, which enhances scalability for RRM algorithms. Options A, B, and C are incorrect because they provide lower maximum AP counts than what is supported by the controller software in this release.
