Which option describes an advantage of UDLD?
A.
It makes the port go immediately into the forwarding state after being connected.
B.
It prevents switch loops by detecting one-way communications on the physical port.
C.
It prevents switched traffic from traversing suboptimal paths on the network.
D.
It prevents switch loops caused by uni-directional point-to-point link condition on Rapid
PVST+ and MST.
E.
It does not generate a spanning-tree topology change upon connecting and disconnecting a
station on a port.
F.
It allows small, unmanaged switches to be plugged into ports of access switches without the
risk of switch loops.
