Question 143/151

Prior to establishing full-mesh IPsec tunnels in a typical Cisco SD-WAN deployment, which mechanism do WAN Edge routers use to exchange key information for data plane encryption?

A. They use vSmart controllers as key exchange servers.

B. They use IKEv2 when exchanging keys with each other.

C. They use vManage as a key exchange server.

D. They use vBond as a key exchange server.

Correct Answer: A

Cisco SD-WAN uses vSmart controllers as key exchange servers to establish and manage IPsec tunnels between WAN Edge routers. The vSmart controllers generate and distribute cryptographic keys to the WAN Edge routers, which are then used to encrypt and decrypt traffic over the IPsec tunnels.
