Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 614

Which protocol is used to encrypt control plane traffic between SD-WAN controllers and SD-WAN endpoints?

Answer options

• A. DTLS
• B. IPsec
• C. PGP
• D. HTTPS

Correct answer: A

Explanation

DTLS is specifically designed to provide security for datagram-based applications, making it suitable for encrypting control plane traffic in SD-WAN environments. IPsec, while also a strong encryption protocol, is primarily used for securing IP packets rather than control plane communications. PGP is typically used for email encryption and not applicable here, and HTTPS is mainly for securing web traffic, not specifically for SD-WAN control plane traffic.
