A network engineer must prevent data corruption due to cross fabric communication in an FCoE environment. Which configuration must be applied to the Cisco Nexus Unified Switches to achieve this objective?
C: "You can prevent data corruption due to cross-fabric talk by configuring an FC-Map, which identifies the Fibre Channel fabric for this switch. When the FC-Map is configured, the switch discards the MAC addresses that are not part of the current fabric."
C. switch(config)# fcoe fcmap 0e.fc.2a
This command configures the FCoE FC-MAP (Fibre Channel-Media Access Control Parameters), and by specifying a unique FC-MAP for the FCoE VLAN, you can help prevent cross-fabric communication. FC-MAP is a unique identifier for an FCoE VLAN, and using different FC-MAPs for different fabrics helps in isolation.

You can prevent data corruption due to cross-fabric talk by configuring an FC-Map that identifies the Fibre Channel fabric for this switch. When the FC-Map is configured, the switch discards the MAC addresses that are not part of the current fabric. An FCF can assign Fabric Provide MAC Addresses (FPMA) to the CNAs consisting of the FC-Map Value for the Fabric and the Fibre Channel ID (FCID) assigned during Fabric Login
