Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 437

Which secure tunnel type should be used to connect one WAN Edge router to other WAN Edge routers?

Answer options

• A. DTLS
• B. SSL VPN
• C. IPsec
• D. TLS

Correct answer: C

Explanation

IPsec is the correct choice because it is specifically designed for securing IP communications by authenticating and encrypting each IP packet in a communication session. DTLS and SSL VPN are more suited for specific applications, while TLS is primarily used for securing web traffic, making them less optimal for WAN Edge router connections.
