What configuration should be applied to an MDS switch in order to be used as the best switch to connect by the CNAs in the fabric?

The FCoE technology is used in a data center and the MDS switches are configured as Fibre Channel Forwarders.

Answer: A

Explanation:

FCoE (Fibre Channel over Ethernet) is a technology that allows Fibre Channel traffic to be encapsulated and transported over Ethernet networks. FCoE requires the use of FCFs (Fibre Channel Forwarders), which are devices that act as bridges between the FCoE and Fibre Channel domains. FCFs can be configured with a priority value that determines their preference for connecting to CNAs (Converged Network Adapters), which are devices that support both Ethernet and Fibre Channel protocols. The priority value ranges from 0 to 1024, with 0 being the lowest and 1024 being the highest. To configure an MDS switch as the best switch to connect by the CNAs in the fabric, the fcoe fcf-priority 1024 command should be applied. This gives the switch the highest priority and makes it the most preferred FCF for the CNAs.
