QUESTION 32
Which four statements about REP configurations on a Cisco ME 3400 switch port are true? (Choose four.)
A. The port must be an NNI type and must be in trunk mode.
B. Use the rep segment number command to enable REP on the switch port.
C. A REP segment cannot be wrapped into a ring topology. REP supports only a topology where each
REP segment has two exit points via two edge switches.
D. The port where the segment terminates is called the edge port.
E. With REP, at least one port is always blocked in any given segment-that is, the alternate port.
F. If a failure occurs within the segment, the blocked port goes to the forwarding state after it goes through
the listening state and the learning state.
Answer: ABDE
