Implementing Cisco Network Security (IINS, legacy) — Question 115

Which next-generation encryption algorithm supports four variants?

Answer options

• A. HMAC
• B. SHA-2
• C. SHA-1
• D. MD5

Correct answer: B

Explanation

SHA-2 is the correct answer because it includes four main variants: SHA-224, SHA-256, SHA-384, and SHA-512. HMAC, SHA-1, and MD5 do not have multiple distinct variants like SHA-2 does.
