Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 641

Which protocol does Cisco SD-WAN use to protect control plane communication?

Answer options

• A. STUN
• B. OMP
• C. IPsec
• D. DTLS

Correct answer: D

Explanation

The correct answer is DTLS, which is specifically designed to secure datagram-based communications, such as those in Cisco SD-WAN's control plane. While IPsec also provides security, it is primarily used for encrypting traffic rather than controlling the plane. STUN and OMP do not focus on control plane security, making them incorrect choices.
