- A
vManage provides a centralized dashboard for configuration, monitoring, and troubleshooting of the entire SD-WAN fabric.
Correct because vManage is the management plane that offers a GUI and API for network administrators to manage all devices.
- B
vSmart controllers are responsible for distributing routing information and policies to all WAN Edge routers in the overlay.
Correct because vSmart is the control plane that uses OMP to disseminate routes and centralized policies.
- C
vBond orchestrators authenticate WAN Edge routers and assist in NAT traversal for establishing tunnels.
Correct because vBond performs initial authentication and provides the public IP/port information needed for NAT traversal.
- D
vSmart controllers are responsible for NAT traversal and public IP discovery for WAN Edge routers behind NAT.
Why wrong: Incorrect because NAT traversal and public IP discovery are functions of the vBond orchestrator, not vSmart.
- E
vManage distributes OMP routes to vEdge routers to populate the overlay routing table.
Why wrong: Incorrect because vManage does not distribute routes; route distribution is performed by vSmart controllers via OMP.
350-401 SD-WAN Architecture Practice Question
This 350-401 practice question tests your understanding of sd-wan architecture. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which three statements about Cisco SD-WAN architecture components and their roles 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
vManage provides a centralized dashboard for configuration, monitoring, and troubleshooting of the entire SD-WAN fabric.
The vManage is the management plane for centralized configuration and monitoring. vSmart is the control plane for route and policy distribution. vBond orchestrates initial authentication and NAT traversal. vEdge routers are data plane devices that forward traffic. vSmart does not handle NAT traversal; that is vBond's role. vManage does not distribute routes; that is vSmart's role.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 350-401 NAT questions on configuration and troubleshooting.
