Which two statements about the fabric interconnect are true? (Choose two.)
A.
The fabric interconnect forwards all broadcast packets on VLAN 311 out of each interface listed in
the Membership.
B.
The fabric interconnect forwards broadcasts on VLAN 311 only when they are received on Po21.
C.
Without any changes to the switch, eth 1/32 could become the designated receiver for VLAN 311.
D.
All multicast traffic from a blade on VLAN 311 goes out of Po21.
E.
IGMP join packets from blades on VLAN 311 goes out Po21.
Explanation:
I believe the answers should be B and C.
The “show platform software enm…” shows so called g-pinned ports (aka designated receivers). A g-pinned port is an ethernet uplink-port, that is chosen to be the broadcast and multicast traffic receiver for a certain VLAN. All other uplinks in this VLAN will drop southbound multicast and broadcast traffic. It has nothing to do with server ports and server northbound multicasts. And the g-pinned ports are also chosen at random. So if Po21 goes down without any changes to the switch, eth 1/32 could very well become the designated receiver.
