Why each option

The vBond orchestrator is responsible for the initial authentication and onboarding of devices into the SD-WAN fabric, and it maintains permanent connections with vSmart controllers.

AIt builds permanent connections with vSmart controllers.Correct

The vBond orchestrator establishes and maintains permanent DTLS/TLS connections with all vSmart controllers to ensure continuous communication and coordination within the SD-WAN overlay network.

BIt builds permanent connections with WAN Edge routers.

vBond facilitates initial authentication and directs WAN Edge routers to vSmart, but WAN Edge routers establish permanent connections with vSmart controllers and other WAN Edges, not with vBond itself.

CIt updates vSmart of WAN Edge routers behind NAT devices using OMP.

vBond assists WAN Edge routers behind NAT devices in discovering their public IP/port and informing vSmart, but it does not use OMP; OMP is used between WAN Edge and vSmart for control plane updates.

DIt maintains vSmart and WAN Edge routers secure connectivity state.

vBond's role is primarily initial orchestration and authentication; vSmart and WAN Edge routers maintain their secure connectivity state independently after the initial setup facilitated by vBond.
