A Cisco DCS administrator is ready to cable two newly racked Fabric Interconnects.
Which two cabling configurations should be used for the heartbeat connectivity? (Choose two.)
A. Connect the Layer 1 portal Fabric Interconnect Ala me Layer 2 port of Fabric Interconnect B.
B. Connect the Layer 2 port of Fabric Interconnect A to the Layer 2 port of Fabric Interconnect B.
C. Connect the Layer 1 port of Fabric Interconnect A to the Layer 1 port of Fabric Interconnect B.
D. Keep the Layer 2 port of both Fabric Interconnects disconnected.
E. Connect the Layer 2 port of Fabric Interconnect A to the Layer 1 port of Fabric Interconnect B.
L1 (L1-to-L1) and L2 (L2-to-L2) high availability ports.
L2 is just port number and does not stand for Layer 2. So this answer B is INCORRECT.
Cisco UCS Manager CLI Configuration Guide”
“To use the cluster configuration, the two fabric interconnects must be directly connected together using Ethernet cables between the L1 (L1-to-L1) and L2 (L2-to-L2) high availability ports, with no other fabric interconnects in between. This allows the two fabric interconnects to continuously monitor the status of each other and quickly know when one has failed. “
