Implementing Cisco Secure Mobility Solutions (SIMOS, legacy) — Question 54

Which two cryptographic technologies are recommended for use with FlexVPN? (Choose two.)

Answer options

• A. SHA (HMAC variant)
• B. Diffie-Hellman
• C. DES
• D. MD5 (HMAC variant)

Correct answer: A, B

Explanation

The correct answer is A and B because SHA (HMAC variant) provides a secure hashing mechanism, and Diffie-Hellman is essential for key exchange. Options C and D are less secure; DES is outdated and vulnerable, while MD5 is considered weak due to its collisions.
