Which action is the vSmart controller responsible for in an SD-WAN deployment?
- A. onboard vEdge nodes into the SD-WAN fabric
- B. gather telemetry data from vEdge routers
- C. distribute security information for tunnel establishment between vEdge routers
- D. manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric
Explanation: + Orchestration plane (vBond) assists in securely onboarding the SD-WAN WAN Edge routers into the SD-WAN overlay (-> Therefore answer “onboard vEdge nodes into the SD-WAN fabric” mentioned about vBond). The vBond controller, or orchestrator, authenticates and authorizes the SD-WAN components onto the network. The vBond orchestrator takes an added responsibility to distribute the list of vSmart and vManage controller information to the WAN Edge routers. vBond is the only device in SD-WAN that requires a public IP address as it is the first point of contact and authentication for all SD-WAN components to join the SD-WAN fabric. All other components need to know the vBond IP or DNS information.
+ Management plane (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)
+ Control plane (vSmart) builds and maintains the network topology and make decisions on the traffic flows. The vSmart controller disseminates control plane information between WAN Edge devices, implements control plane policies and distributes data plane policies to network devices for enforcement (-> Answer “distribute security information for tunnel establishment between vEdge routers” is about vSmart)
