350-601 Network Practice Question
Which VXLAN component is responsible for encapsulating and decapsulating Ethernet frames into UDP packets?
⚠ Common exam trap
Cisco often tests the distinction between the VTEP (the device that does encapsulation) and the VXLAN tunnel (the logical path), so candidates mistakenly pick 'VXLAN tunnel' because they associate 'tunnel' with encapsulation, but the tunnel is the path, not the endpoint.

Correct answer & explanation
✓
VTEP
The VTEP (VXLAN Tunnel Endpoint) is the device that performs encapsulation and decapsulation of Ethernet frames into UDP packets. It is the edge component in a VXLAN network that maps tenant traffic to VXLAN segments and handles the actual tunneling by adding the VXLAN header (including VNI) and outer UDP/IP headers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
VNI
Why it's wrong here
VNI is the network identifier, not the endpoint.
- ✗
VXLAN tunnel
Why it's wrong here
Tunnel is the logical path, not the endpoint.
- ✗
VXLAN gateway
Why it's wrong here
Gateway connects VXLAN to non-VXLAN but does not encapsulate.
- ✓
VTEP
Why this is correct
VTEP performs VXLAN encapsulation/decapsulation.
