A customer is configuring VSANs in a Cisco UCS domain. After configuring the VSANs 3840, 3841, and 3842 in FC end-host mode, the customer sees that these VSANs are not operational and that Cisco UCS Manager is raising faults. What is the cause of this problem?
A. VSANs 3840, 3841, and 3842 should be in the allowed list on the trunk to clear the fault.
B. VSANs 3840 to 4079 cannot be used in Fibre Channel end-host mode in a Cisco UCS domain.
C. The fabric interconnect needs to be configured in switching mode and the VSANs need to be allowed on the trunk.
D. Use the UCS CLI to clear the fault on the VSAN trunk to forward the VSANs with faults.
