Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 397

Which algorithm is an NGE hash function?

Answer options

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

Correct answer: D

Explanation

SHA-2 is the correct answer because it includes enhancements over its predecessor SHA-1 and is considered more secure, making it suitable for NGE applications. HMAC, while secure, is not a hash function but rather a construction for creating a message authentication code. MD5 is widely recognized as insecure, and SHA-1 has known vulnerabilities that disqualify it from being an NGE hash function.
