The setting default-forwarding=no prevents wireless clients from communicating with each other over the same access point interface. This enables client isolation — each device can only reach the gateway (router), not other wireless clients.
A.✔Correct – This enables client isolation by blocking inter-client communication.
B.✘Incorrect – This limits how many clients can connect, not their ability to talk to each other.
C.✘Incorrect – Prevents new clients from associating, unrelated to inter-client traffic.
D.✘Incorrect – Only default-forwarding affects client-to-client visibility.
Extract from MTCNA Course Material – Wireless Security and Isolation:
“default-forwarding=no prevents wireless clients from communicating with each other on the same AP interface.”
Extract from René Meneses Study Guide – Wireless Interface Settings:
“To isolate wireless clients, use default-forwarding=no. This ensures clients can’t ping or access one another.”
Extract from MikroTik Wiki – Wireless Interface Options:
“default-forwarding=no stops traffic between clients. Only traffic to the AP is allowed.”
