NSE 7 – SD-WAN 6.4 — Question 54

Which two protocols in the IPsec suite are most used for authentication and encryption? (Choose two.)

Answer options

• A. Internet Key Exchange (IKE)
• B. Secure Shell (SSH)
• C. Security Association (SA)
• D. Encapsulating Security Payload (ESP)

Correct answer: A, D

Explanation

The correct answers are A and D because Internet Key Exchange (IKE) is used for establishing security associations and managing keys, while Encapsulating Security Payload (ESP) provides encryption and authentication for IP packets. Options B and C are not part of the IPsec suite; SSH is a separate protocol for secure remote access, and Security Association (SA) refers to a concept rather than a protocol.
