350-601 Network Practice Question
A network engineer is planning to implement VPC in a Cisco Nexus data center. Which two statements about VPC components are true? (Choose two.)
⚠ Common exam trap
Cisco often tests the misconception that the peer-link carries only control-plane traffic, but in reality it also carries data-plane traffic for orphan ports and traffic that needs to reach the other VPC peer.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VPC consistency checks ensure that both peers have identical configurations for VPC member ports.
VPC consistency checks are a critical feature that ensures both VPC peers have identical configurations for member ports, such as VLANs, allowed VLAN lists, and interface parameters. If configurations diverge, the VPC will suspend member ports to prevent traffic disruption or loops. This check is performed via the Cisco NX-OS Consistency Checker, which validates parameters like STP settings, port type, and allowed VLANs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
VPC member ports can be configured on only one of the VPC peers to avoid loops.
Why it's wrong here
Member ports must be configured on both peers for the same VPC VLAN.
- ✓
VPC consistency checks ensure that both peers have identical configurations for VPC member ports.
Why this is correct
Correct. Consistency checks prevent misconfigurations that could cause loops.
- ✓
The VPC peer-keepalive link is used to monitor the liveness of the VPC peer.
Why this is correct
Correct. The keepalive link sends heartbeats to detect peer failure.
- ✗
VPC requires an IGP routing protocol between the peers to exchange MAC addresses.
Why it's wrong here
VPC uses the peer-link for MAC synchronization; no routing protocol is required.
- ✗
The VPC peer-link carries only control-plane traffic between the VPC peers.
Why it's wrong here
The peer-link carries both control and data traffic (e.g., BPDUs, multicast, and unicast).
