Which two algorithms authenticate a user for SNMPv3 on a WAN Edge router?

MD5 and SHA-2 are correct because SNMPv3 uses these hashing algorithms for authentication. MD5 (Message Digest 5) provides a 128-bit hash, while SHA-2 (Secure Hash Algorithm 2) offers stronger options like SHA-256 or SHA-512. These algorithms create a one-way hash of the authentication key and the SNMP message, ensuring data integrity and user authenticity. AES-256 and AES-128 are incorrect because AES (Advanced Encryption Standard) is an encryption algorithm used for privacy (confidentiality) in SNMPv3, not for authentication. While crucial for secure communication, encryption and authentication serve different purposes. SHA-1 is incorrect because while it is an authentication algorithm, it is considered less secure than SHA-2 and is generally not recommended for new deployments due to known vulnerabilities.
