Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 142

A customer Wi-Fi deployment is experiencing the sticky client problem and must enable the optimized roaming feature. The wireless clients have valid security credentials for an SSID and can see an AP that offers that SSID to join. What must be configured to enhance roaming?

Answer options

• A. RSSI threshold
• B. disable DFS
• C. disable 802.11k
• D. enable data rates

Correct answer: A

Explanation

Configuring the RSSI threshold is essential because it helps in deciding when a client should switch to a stronger access point, thus improving roaming efficiency. Disabling DFS would not resolve sticky client issues, while disabling 802.11k could hinder roaming optimizations. Enabling data rates does not directly address the roaming problem in this context.
