ACD.

vPC+ is a technology that enables the extension of virtual PortChannels (vPC) across a FabricPath network. vPC+ allows the configuration of multiple virtual switches to participate in a single vPC domain. In this context, the FabricPath network acts as a Layer 2 transport between the vPC domain devices. Here are the three true statements regarding the configuration of vPC+:

A. The FabricPath switch ID must be configured under the vPC domain.

The FabricPath switch ID must be manually configured on every switch in the FabricPath network to provide a unique identifier. A vPC+ domain can contain multiple switches, so the FabricPath switch ID must be configured under the vPC domain to ensure consistency across all switches.

B. The virtual switch ID of vPC+ must be configured under the FabricPath domain.

The virtual switch ID (VSID) is a unique identifier for each virtual switch participating in the vPC+ domain. The VSID is used to distinguish between different virtual switches when communicating across the FabricPath network. Since FabricPath provides the Layer 2 transport between the vPC domain devices, the VSID must be configured under the FabricPath domain.

D. The vPC+ peer link must be configured as a Cisco FabricPath core port.

The vPC+ peer link is the link that connects the two vPC+ switches together. This link must be configured as a Cisco FabricPath core port to ensure that the vPC+ traffic is transported across the FabricPath network. FabricPath core ports are used to transport Layer 2 traffic across the FabricPath network and are required for vPC+ to function properly.

Therefore, options A, B, and D are the three statements that are true regarding the configuration of vPC+. Option C is incorrect because the type of interface used as vPC+ peer links is not limited to F1 interfaces only. Option E is also incorrect because there is no such thing as a FabricPath subswitch ID. Option F is incorrect because there is no requirement for a minimum number of virtual switches in the FabricPath domain for vPC+ to function.
