Certified Ethical Hacker (CEH v10) — Question 57

Which component of IPsec performs protocol-level functions that are required to encrypt and decrypt the packets?

Answer options

• A. Internet Key Exchange (IKE)
• B. Oakley
• C. IPsec Policy Agent
• D. IPsec driver

Correct answer: A

Explanation

The Internet Key Exchange (IKE) is the component of IPsec that handles the necessary protocol-level functions for encrypting and decrypting packets. The other options, such as Oakley, are related to key management but do not directly perform the encryption and decryption tasks. The IPsec Policy Agent and IPsec driver are involved in policy enforcement and transport but are not responsible for the encryption processes.
