Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 539

What is a characteristic of Cisco SD-WAN?

Answer options

• A. uses unique per-device feature templates
• B. requires manual secure tunnel configuration
• C. uses control plane connections between routers
• D. operates over DTLS/TLS authenticated and secured tunnels

Correct answer: D

Explanation

The correct answer is D because Cisco SD-WAN establishes secure connections using DTLS/TLS protocols, ensuring data integrity and confidentiality. Options A and B are incorrect as they misrepresent the automated capabilities and features of Cisco SD-WAN, while option C is misleading because control plane connections are part of the architecture but not the defining characteristic.
