Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 22

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?

Answer options

• 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

Correct answer: D

Explanation

The correct answer is D because the WAN Edge router establishes a DTLS or TLS tunnel with the vSmart controller for control plane communications and an IPsec tunnel with other WAN Edge routers for data plane communication. The other options incorrectly associate the tunnels with either the wrong controllers or with the wrong types of tunnels.
