Which description of the connection between two fabric interconnects in a cluster configuration is true?

The correct answer is D. must be connected directly by using Ethernet cables between L1-to-L1 and L2-to-L2 high-. In a Cisco UCS Fabric Interconnect cluster, the two FIs must be directly connected using high-speed Ethernet cables between their L1 ports and between their L2 ports.

Why each option

In a Cisco UCS Fabric Interconnect cluster, the two FIs must be directly connected using high-speed Ethernet cables between their L1 ports and between their L2 ports.

Amust be connected directly by using any ports

While a direct connection is required, it must use specific L1 and L2 cluster ports, not 'any ports', to ensure proper cluster operation.

Bmust be connected virtually

Fabric Interconnects in a cluster configuration require physical, direct connections, not virtual ones, to maintain reliable cluster communication and redundancy.

Cmust be connected directly by using Ethernet cables between L1-to-L2 and L2-to-L1 high-

The correct connection pattern for cluster links is L1-to-L1 and L2-to-L2 for direct communication, not cross-connecting L1-to-L2 and L2-to-L1.

Dmust be connected directly by using Ethernet cables between L1-to-L1 and L2-to-L2 high-Correct

Cisco UCS Fabric Interconnects in a cluster configuration require dedicated, direct Ethernet cable connections between the L1 port of one FI and the L1 port of the other FI, and similarly between their L2 ports. These cluster interconnects are essential for state synchronization and high availability.
