Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 592

Which algorithm does ISAKMP use to securely derive encryption and integrity keys?

Answer options

• A. RSA
• B. AES
• C. 3DES
• D. Diffie-Hellman

Correct answer: D

Explanation

The correct answer is D, Diffie-Hellman, as it is specifically designed for securely exchanging cryptographic keys. RSA, AES, and 3DES are used for encryption but do not facilitate the key exchange process that ISAKMP relies on to derive keys securely.
