- A
It is used to forward data traffic between vPC peers
Why wrong: Data forwarding uses the peer-link, not keepalive.
- B
It must be a dedicated Layer 2 link between vPC peers
Why wrong: The keepalive is Layer 3 and can be routed through the management network.
- C
It carries BPDUs to prevent loops
Why wrong: BPDUs are handled by STP, not the keepalive link.
- D
It is a Layer 3 link used to verify the health of the vPC peer
The peer-keepalive is a Layer 3 heartbeat used to detect peer failure.
