Explanation
SNMPv3 is the only version of SNMP that provides both authentication and encryption (privacy) for management traffic. It uses Username Security Model (USM) with support for MD5/SHA authentication and DES/AES encryption to secure SNMP messages in transit. SNMPv1 (Option A) uses plaintext community strings with no security. SNMPv2 (Option C) is not a widely deployed standalone version. SNMPv2c (Option D) also uses plaintext community strings for authentication and provides no encryption. For any deployment where security of management plane traffic is required - such as collaboration environments - SNMPv3 with privacy mode (authPriv) is the correct choice.
