Explanation

Explanation

Enable P2P Blocking (Option B) is correct because P2P (Peer-to-Peer) Blocking is a WLAN security feature on Cisco wireless controllers that prevents wireless clients associated to the same WLAN/SSID from communicating directly with each other - effectively isolating clients and ensuring all traffic must pass through the network infrastructure rather than flowing laterally between devices.

Option A (Client Exclusions) is incorrect because Client Exclusions is used to temporarily ban clients that exhibit suspicious behavior (e.g., excessive authentication failures), not to prevent inter-client communication. Option C (Aironet IE) is incorrect because Aironet Information Elements are Cisco-proprietary extensions added to beacon frames for enhanced features like load balancing, and disabling them has no impact on client-to-client traffic. Option D (Wi-Fi Direct Client Policy) is incorrect because this setting manages Wi-Fi Direct connections (device-to-device connections outside the infrastructure network), not standard client isolation on a WLAN.

Memory Tip: Think of P2P Blocking = "No talking to your neighbors" - it blocks peer-to-peer (client-to-client) traffic on the same WLAN, which is exactly what you need when clients shouldn't be able to reach each other directly.
