350-601 Network Practice Question
Which three components are part of the VXLAN overlay architecture? (Choose three.)
⚠ Common exam trap
Cisco often tests the distinction between overlay components (VTEP, VNI) and underlay infrastructure (spine switches, IP transport), leading candidates to incorrectly include spine switches as part of the overlay architecture.
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
✓
VTEP (Virtual Tunnel Endpoint)
A VTEP is a fundamental component of VXLAN overlay architecture because it encapsulates and decapsulates Layer 2 Ethernet frames into UDP packets for transport over the IP underlay network. It serves as the tunnel endpoint where VXLAN traffic originates and terminates, enabling Layer 2 extension across Layer 3 boundaries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
VTEP (Virtual Tunnel Endpoint)
Why this is correct
Correct. VTEPs encapsulate and decapsulate VXLAN frames.
- ✗
VPC peer-link
Why it's wrong here
VPC peer-link is a Cisco feature, not part of VXLAN architecture.
- ✗
Spine switches only in VXLAN
Why it's wrong here
Spine switches are part of the underlay, but VXLAN architecture includes all underlay devices, not just spines.
- ✓
IP transport network (underlay)
Why this is correct
Correct. The underlay provides IP connectivity between VTEPs.
- ✓
VNI (VXLAN Network Identifier)
Why this is correct
Correct. VNI identifies the Layer 2 segment in VXLAN.
