Exam 350-401 topic 1 question 14 discussion

vSmart functions: 1. vSmart is the brain of the entire system. 2. Works with vBond to authenticate Viptela devices as they join the network. 3. Builds Control Plane connections with vEdge using TLS. 4. Orchestrate connectivity between vEdges via the policies there by creating the network topology. 5. Acts as a Route reflector by advertising the branches prefixes based on the policy. 6. Shares the data plane keys of a vEdge with other vEdges based on the policy to allow them to build the tunnels – IKEless IPSEC. 7. Policies are configured on vSmart.

Provided answer is correct. vSmart controllers also implement all the control plane policies created on vManage CCNP and CCIE Enterprise Core ENCOR 350-401 Official Cert Guide Pg 634

C is correct

correct, in the cEdge router you can run: ' show sdwan policy from-vsmart " this gives you the policies for data policy and app route policy given to the router by the vSmart.

It is the distributor of policies. "C" is the correct answer

Correct Answer: C As with centralized control policy, you provision centralized data policy on the Cisco vSmart controller, and that configuration remains on the Cisco vSmart controller. The effects of data policy are reflected in how the Cisco vEdge devices direct data traffic to its destination.

The main characteristics of the control plane with Cisco vSmart controllers are as follows: Facilitates fabric discovery Disseminates control plane information between the Cisco WAN Edge routers Distributes data plane and application-aware routing policies to the Cisco WAN Edge routers Implements control plane policies, such as service chaining, multitopology, and multihop Dramatically reduces control plane complexity Highly resilient

- onboard WAN Edge nodes into the Cisco SD-WAN fabric. (vBond) - gather telemetry data from WAN Edge routers. (vAnalytics) - distribute policies that govern data forwarding performed within the Cisco SD-WAN fabric. (vSmart) - handle, maintain, and gather configuration and status for nodes within the Cisco SD-WAN fabric. (vManage)

C is correct

C is correct

Given answer is correct.

Control Plane – vSmart is the Controller in Viptela solution and manages the Control Plane. vSmart does all the complex work of path calculation, route advertisement etc. there by offloading the Data Plane to do only packet forwarding.
