Refer to the exhibit. 

The network topology that is shown in the exhibit has two aggregation switches (SW1 and SW2). The access layer switch connects to both aggregation switches. On SW1 and SW2, ports connecting to the access layer switches are configured as vPC member ports. SW1 and SW2 are also connected using a port channel that is configured as a vPC peer link. Which statement describes the use of the vPC peer-keepalive link in this topology? 

Answer options:

A. The peer-keepalive link is used for synchronizing MAC addresses between Agg1 and Agg2.
B. The peer-keepalive link is used for control plane traffic. The peer link is used for the data plane.
C. The peer-keepalive link is used to resolve dual-active scenarios, where the peer link connectivity is lost.
D. The peer-keepalive link is used for the communication of orphaned ports.
