Selected Answers: A, D


Loop guard is another loop prevention feature. However, unlike loop protection, root guard, and BPDU guard, - does not rely on BPDUs and the port state. Instead, loop guard works by periodically broadcasting frames on the native VLAN of a port. A loop is detected when the same loop guard frame is received on the sender switch, which is followed by the port getting shut down for the time specified in the loop-guard-timeout setting (45 minutes by default).
