問題文
A switch port faces a server, and the operators want to make sure that the server cannot pretend to be the gateway of the segment. Which protection addresses that?
選択肢
- The port is marked as facing hosts rather than routers, and the frames that a gateway would legitimately send are discarded when they arrive on it.
- The port is given a bandwidth limit rather than a role, and the frames that a server would legitimately send are discarded when they exceed it.
- The port is configured to accept one address rather than many, and the frames that a different address would send are discarded when they arrive.
- The port is placed in its own segment rather than a shared one, and the frames that a server would send are discarded unless a gateway is configured there.
