Which three statements about the configuration of vPC+ are true? (Choose three.)
A. The FabricPath switch ID must be configured under the vPC domain.
B. The virtual switch ID of vPC+ must be configured under the FabricPath domain.
C. On the Cisco Nexus 7000 switch, F1 interfaces must be used as the vPC+ peer links.
D. The vPC+ peer link must be configured as a Cisco FabricPath core port.
E. The FabricPath subswitch ID must be configured under the vPC domain.
F. There has to be atleast 4 virtual switches in the FabricPath domain.
This is a tricky question.
subswitch ID equals to virtual switch ID. I think the answer should be CDE.
******** From Nexus 5000 NX-OS config guide ***********
Assigns a static vPC+ ID to the vPC+ peer. The range is from 0 to 4094. This static ID is the virtual switch ID for FabricPath encapsulation.
