Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 17

What is a default protocol for control plane connection?

Answer options

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

Correct answer: D

Explanation

DTLS is the correct answer as it is specifically designed to provide communications privacy for datagram protocols, making it suitable for control plane connections. HTTPS, TLS, and IPsec are not designed as default protocols for control plane communication, as they serve different purposes, such as web security and secure tunneling respectively.
