Which SNMP version supports the user and group configuration in its authentication security model?

• A. V1
• B. V2
• C. V3
• D. V4

Answer: (C)

SNMPv3 is the version that provides user-based authentication and group-based access control as part of its security model. In earlier versions, authentication relies on a simple community string shared across devices, with no per-user identity or encryption. SNMPv3 introduces the User-based Security Model (USM), which defines individual users with their own authentication (such as MD5 or SHA) and privacy options (encryption), and the View-based Access Control Model (VACM), which maps users to groups and controls what data each group can access. This combination enables precise, per-user and per-group security configuration, which is why SNMPv3 is the correct choice.
