350-401 Practice Question: Which three statements about SD-WAN segmentation…
Which three statements about SD-WAN segmentation and multi-tenancy are true? (Choose three.)
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
✓
Each VPN in SD-WAN corresponds to a separate VRF on the edge device, providing Layer 3 isolation.
VPN segmentation in SD-WAN uses VRFs (VPN IDs) to isolate traffic. Service-side routing uses VRFs, and transport-side uses TLOCs. OMP carries VPN membership information. Extranet allows controlled sharing between VPNs. VPN 0 is for transport, not service. Multiple VRFs can be used to support multi-tenancy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Each VPN in SD-WAN corresponds to a separate VRF on the edge device, providing Layer 3 isolation.
Why this is correct
Correct because VPN IDs map to VRFs, isolating routing and forwarding domains.
- ✓
OMP advertises VPN membership information so that edge devices know which VPNs are reachable via each TLOC.
Why this is correct
Correct because OMP includes VPN ID in route advertisements, enabling per-VPN reachability.
- ✓
Extranet VPN configuration allows selected routes to be shared between different VPNs on the same edge device.
Why this is correct
Correct because extranet enables controlled route leaking between VPNs, e.g., for shared services.
- ✗
VPN 0 is used for service-side connectivity, such as connecting to a corporate LAN or data center.
Why it's wrong here
Incorrect because VPN 0 is the transport VPN used for WAN interfaces; service-side VPNs are numbered 1-65535 (except 0).
- ✗
Multi-tenancy in SD-WAN requires separate physical edge devices for each tenant to ensure isolation.
Why it's wrong here
Incorrect because multi-tenancy can be achieved with a single edge device using multiple VPNs/VRFs, not requiring separate hardware.
