C. vPC management link
D. vPC peer link

Correct Answer: D
Explanation/Reference:
The vPC peer link is the most important connectivity element in the vPC system. This link is used to create the illusion of a single control plane by forwarding Bridge Protocol data units (BPDUs) or Link Aggregation Control Protocol (LACP) packets to the primary vPC switch from the secondary vPC switch.
