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
✓
Centralized control policies are configured on the vSmart controller and affect route advertisement and path selection.
Centralized control policies are applied on vSmart to influence routing (e.g., path selection), while localized data policies are applied on edge devices for QoS, ACL, and forwarding. App-route policies are a type of centralized data policy. vManage is for configuration, not policy enforcement. Centralized data policies are applied on vSmart, not edge devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Centralized control policies are configured on the vSmart controller and affect route advertisement and path selection.
Why this is correct
Correct because control policies on vSmart manipulate OMP routes and TLOCs to influence routing decisions.
- ✓
Localized data policies, such as QoS and ACL, are configured on vEdge or cEdge routers and affect traffic forwarding.
Why this is correct
Correct because localized policies are applied directly on the edge devices for per-packet actions.
- ✗
Application-aware routing policies are a type of localized control policy that steers traffic based on application performance.
Why it's wrong here
Incorrect because app-route policies are centralized data policies, not localized control policies.
- ✗
Centralized data policies are applied on the edge devices to enforce per-tunnel QoS and ACL rules.
Why it's wrong here
Incorrect because centralized data policies are applied on vSmart, not on edge devices.
- ✗
vManage is the primary device where all SD-WAN policies are enforced and processed in real time.
Why it's wrong here
Incorrect because vManage is the management plane for configuration and monitoring, not for policy enforcement.
