Exam 350-401 topic 1 question 32 discussion

- onboard vEdge nodes into the SD-WAN fabric (vBond) - gather telemetry data from vEdge routers (vAnalytics) - distribute security information for tunnel establishment between vEdge routers (vSmart) - manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric (vManage)

C should be the answer. Vsmart should be controlling edge routers

The vSmart controller is responsible for managing the control plane in a Cisco SD-WAN deployment, including routing information exchange, policy enforcement, secure control plane connections, overlay topology management, service chaining, and analytics. Its role is central to maintaining the overlay network’s efficiency, security, and policy compliance across distributed sites.

C is correct

In an SD-WAN deployment, the vSmart controller is primarily responsible for: D. Manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric The vSmart controller acts as a centralized brain of the SD-WAN architecture, responsible for orchestrating and managing the SD-WAN fabric. It's involved in the control plane operations, managing the configuration, policies, and status information for the network elements, including vEdge routers. Specifically, the vSmart controller performs tasks such as policy distribution, control plane intelligence, configuration management, and providing routing information to the SD-WAN edge devices (vEdge routers). It helps in making forwarding decisions and ensuring that the SD-WAN fabric operates according to the defined policies and configurations across the network.

C is correct

C is correct

C is correct

(vManage) is responsible for central configuration and monitoring. The vManage controller is the centralized network management system that provides a single pane of glass GUI interface to easily deploy, configure, monitor and troubleshoot all Cisco SD-WAN components in the network. (-> Answer "manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric" and answer "gather telemetry data from vEdge routers" are about vManage)

Ref: Cisco SD-WAN Getting Started Guide - The Cisco SD-WAN Solution [Cisco SD-WAN] – Cisco “… Cisco SD-WAN Components … Primary Cisco SD-WAN Components … Cisco vSmart Controller … Each Cisco vSmart Controller establishes and maintains a control plane connection with each edge router in the overlay network. … Each connection, which runs as a DTLS tunnel, is established after device authentication succeeds, and it carries the encrypted payload between the Cisco vSmart Controller and the edge router. …” A. onboard vEdge nodes into the SD-WAN fabric Wrong answer. B. gather telemetry data from vEdge routers Wrong answer. C. distribute security information for tunnel establishment between vEdge routers Correct answer. D. manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric Wrong answer.

It provides the control plane for the network fabric, facilitates the data plane encryption between WAN edges, and propagates the centralized policies that establish and direct the fabric

C is the correct answer because it established the DTLS Tunnel. After successful authentication, each vSmart controller establishes a permanent DTLS tunnel to each SD-WAN router in the SD-WAN fabric and uses these tunnels to establish Overlay Management Protocol (OMP) neighborships with each SD-WAN router

I would say C as the vsmart device is connected with security

C 100% correct

C. From the SD-WAN Design Guide: Each WAN Edge router generates one AES key per TLOC and transmits this information to the vSmart controller in OMP route packets, which is then distributed to all WAN Edge routers.

Correct answer is C

The correct answer is C according to Boson The vSmart controller distributes security information between vEdge routers to facilitate data plane IPSEC tunnel creation. The vSmart uses OMP to distribute routing information, security keys, and policy configurations through DTLS tunnels th the vEdge routers. The vEdge routers can then use this information to determine the appropriate next hop for data plane traffic, to create IP Sec tunnels to other vEdge routers for data plane traffic, and to ensure that SLAs are met and that traffic policies are enforced. Remember, the vBond authenticates the vEdge to the vSmart controller during the INITIAL sequences. The vSmart helps orchestrate the tunnel creation between vEdges.
