Which of the following is true concerning Fibre Channel communications on a Cisco Unified
Computing System?
A.
Each VSAN requires a dedicated VLAN to carry FCoE traffic.
B.
FCoE VLANs are created like Ethernet VLANs on Cisco Unified Computing System Manager.
C.
FCoE VLANs may overlap with Ethernet VLANs.
D.
Cisco Unified Computing System Manager supports a maximum of 128 active VSANs.
A named VSAN creates a connection to a specific external SAN. The VSAN isolates traffic to that external SAN, including broadcast traffic. The traffic on one named VSAN knows that the traffic on another named VSAN exists, but cannot read or access that traffic.
Like a named VLAN, the name that you assign to a VSAN ID adds a layer of abstraction that allows you to globally update all servers associated with service profiles that use the named VSAN. You do not need to reconfigure the servers individually to maintain communication with the external SAN. You can create more than one named VSAN with the same VSAN ID
You must configure each named VSAN with an FCoE VLAN ID. This property determines which VLAN is used for transporting the VSAN and its Fibre Channel packets
