Question
Refer to the exhibit. As the new network designer for a manufacturing company, you are designing this resilient Ethernet ring for the plant Ethernet network that is connected to the core, which does not use STP. Both edge ports are on the same switch in a ring segment. There is connectivity between the edge ports throughout the segment, so you can create a redundant connection between any two switches in the ring. Which three options are characteristics of this design? (Choose 3)

Explanation
REP segments have thefollowing characteristics: If all ports in a segment are operational, one port (referred to as the alternate port) is in the blocked state for each VLAN. If VLAN load balancing is configured, two ports in the segment control the blocked state of VLANs. If one or more ports in a segment is not operational, and cause a link failure, all ports forward traffic on all VLANs to ensure connectivity. In case of a link failure, alternate ports are unblocked as quickly as possible. When the failed link is up, a logically blocked portper VLAN is selected with minimal disruption to the network.
