Why each option

SNMPv3 introduced the User Security Model (USM) with three tiered security levels, including AuthPriv which provides both authentication and encryption. Earlier SNMP versions rely on community strings and lack true security features.

SNMP version 2 (Party-based SNMP) was never widely deployed and does not implement USM or the AuthPriv security level.

B3Correct

SNMPv3 is the only SNMP version that supports the AuthPriv security level through its User Security Model (USM). AuthPriv uses HMAC-based message authentication combined with DES or AES encryption, capabilities that are entirely absent in SNMPv1 and SNMPv2c.

C2c

SNMPv2c uses community-based security with cleartext community strings and has no concept of authentication or privacy security levels.

D3c

SNMPv3c is not a real or standardized SNMP version; only v1, v2c, and v3 are recognized standards.

Concept tested: SNMPv3 USM AuthPriv security level
