Question

Which three options are the main security features in SNMPv3? (Choose three)

Options

• Aauthentication
• BMIB persistence
• Cmessage integrity
• Dauthorization
• Eencryption
• Faccounting

Explanation

This question identifies the three core security features provided by SNMPv3, which significantly enhances security over previous SNMP versions.

Common mistakes.

• B. MIB persistence refers to the ability of MIB objects to retain their values across reboots, which is a feature of MIBs, not a security feature of SNMPv3.
• D. While authorization is a general security concept, SNMPv3 specifically focuses on authentication, integrity, and privacy for message exchange, rather than a distinct 'authorization' feature within its message security model.
• F. Accounting tracks user activities and resource usage, which is not a primary security feature built into the SNMPv3 message processing itself, but rather a separate security service that might consume SNMP data.
