NSE 7 – SD-WAN 7.0 — Question 2

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

Answer options

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

Correct answer: A, C

Explanation

Encapsulating Security Payload (ESP) is primarily used for encryption and providing confidentiality in IPsec, while Internet Key Exchange (IKE) is essential for establishing security associations and managing keys. The other options, Secure Shell (SSH) and Security Association (SA), do not directly serve the dual functions of authentication and encryption within the IPsec framework.
