350-601 Network Practice Question
Which TWO characteristics are true about Cisco VPC? (Choose two)
⚠ Common exam trap
Cisco often tests the misconception that vPC keepalive uses Layer 2 connectivity, when in fact it requires Layer 3 reachability, and that vPC member ports can have mismatched VLANs, which is not allowed because the VLAN configuration must be consistent across both peers for the vPC to operate correctly.

Correct answer & explanation
✓
VPC allows dual-homing of a server to two different switches.
Cisco Virtual PortChannel (vPC) allows a server to be dual-homed to two different switches, enabling active-active load balancing and link redundancy. This is achieved by making the two switches appear as a single logical switch to the downstream device using the vPC protocol, which synchronizes state and forwarding information across the peer link.
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 allows dual-homing of a server to two different switches.
Why this is correct
VPC enables a server to connect to two switches simultaneously, treating them as a single logical node.
- ✗
VPC keepalive uses Layer 2 connectivity.
Why it's wrong here
Keepalive uses Layer 3 reachability (IP) and is often sent via the management VRF.
- ✗
VPC requires a dedicated management VLAN.
Why it's wrong here
No dedicated management VLAN is required; the keepalive link can use an existing management interface.
- ✓
VPC peer-link can be a single link or EtherChannel.
Why this is correct
The peer-link is typically a port-channel but can also be a single link.
- ✗
VPC member ports can be on different VLANs on each peer.
Why it's wrong here
For a given VPC VLAN, the member ports must be in the same VLAN on both switches.
