down and there is no active STP port state on the bound Ethernet interface. What should the STP
port state be to correct this issue?

B. The bound interface should be in an STP blocking state for both the native VLANand the
member FCoE VLAN that is mapped to the active VSAN.
C. The bound interface should be in an STP learning state for both the native VLANand the
member FCoE VLAN that is mapped to the active VSAN.
D. The bound interface should be in an STP forwarding state for the native VLAN only.

address
B. segment VLANs using secondary IP addresses, which will reduce the management domain
C. create a separate VDC to scale VLAN limitation and upgrade to Cisco Nexus 7018 Switch
