Explanation

P2P Blocking Explanation

Why C is Correct: P2P (Peer-to-Peer) blocking is specifically designed to prevent wireless clients on the same WLAN from communicating directly with each other. When guest users can see and access other guest devices, it means lateral (client-to-client) traffic is permitted - enabling P2P blocking on the guest WLAN forces all client traffic through the access point/controller, effectively isolating guests from one another.

Why the Distractors Are Wrong:

• A (MFP Client Protection): Management Frame Protection is a security feature that protects against deauthentication/disassociation attacks and rogue devices - it does not control client-to-client communication.
• B (Split Tunneling): Split tunneling determines whether traffic is routed through a VPN tunnel or exits locally - it has no relevance to blocking communication between wireless clients on the same SSID.
• D (Wi-Fi Direct Policy): Wi-Fi Direct governs device-to-device connections outside of a traditional WLAN infrastructure (like Miracast or AirDrop) - it does not address standard guest client isolation.

Memory Tip: Think of P2P blocking = "No talking between peers" - whenever a question involves guests or users accessing each other's devices on the same WLAN, P2P blocking is your go-to isolation tool.
