CCNP Practice Question: Which three statements about SD-WAN (Cisco…
Which three statements about SD-WAN (Cisco Catalyst SD-WAN) 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
✓
The vSmart controller is responsible for distributing control plane information such as OMP routes and policies to the WAN edge routers.
Cisco SD-WAN uses a centralized vSmart controller for policy and routing, vBond for orchestration and authentication, and vManage for management. vEdge routers establish secure DTLS/TLS tunnels to controllers and can use multiple transport interfaces. The control plane is separate from the data plane. vSmart does not forward data traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The vSmart controller is responsible for distributing control plane information such as OMP routes and policies to the WAN edge routers.
Why this is correct
Correct because vSmart is the centralized control plane component that advertises routes and policies using OMP.
- ✓
The vBond controller is primarily used for device authentication and orchestration of initial connections.
Why this is correct
Correct because vBond authenticates vEdge/cEdge devices and helps them discover vSmart and vManage.
- ✗
The vManage controller forwards all data traffic between branch sites.
Why it's wrong here
Incorrect because vManage is a management plane component; it does not forward data traffic.
- ✓
WAN edge routers can connect to the SD-WAN fabric using multiple transport interfaces (e.g., MPLS, Internet, LTE).
Why this is correct
Correct because Cisco SD-WAN supports multi-homing with different transport types for redundancy and load balancing.
- ✗
OMP (Overlay Management Protocol) runs between vEdge routers and the vManage controller.
Why it's wrong here
Incorrect because OMP runs between vEdge routers and the vSmart controller, not vManage.
