A network administrator is bringing up one WAN Edge router for branch connectivity. Which types of tunnels form when the WAN edge router connects to the Cisco SD-WAN fabric?
A.
DTLS or TLS tunnel with vSmart controller and IPsec tunnel with vBond controller
B.
DTLS or TLS tunnel with vBond controller and IPsec tunnel with vManage controller
C.
DTLS or TLS tunnel with vBond controller and IPsec tunnel with other WAN Edge routers
D.
DTLS or TLS tunnel with vSmart controller and IPsec tunnel with other WAN Edge routers
D is the correct answer.
1. VBOND will make only DTLS connection, TLS connection will not happen between vBond and vEdge.
2. vBond connection is temporary
3. vEdges will make IPSec tunnels over data plane
dear Team what is the solution to this Q An MPLS connection on R2 must extend to R1 Users behind R1 must have dual connectivity for data traffic Which configuration provides R1 control connectivity over the MPLS connection?
C is the correct answer, the minimal config on the Edge device contains the vBond IP or DNS name, so first comms would be to the vBond through TLS/DTLS tunnel connection.

Technically C is also correct, but the DTLS tunnel to the vBond is torn down after the Edge receives the vManage & vSmart IP's.
