Infrastructure Security

SNMPv2 has been deployed throughout a network to manage all network devices. You have been asked to migrate instead to an SNMPv3 solution. What is the greatest advantage of migrating from SNMPv2 to SNMPv3?

  • A Enhanced security, including encryption of passwords
  • B Enhanced performance, supporting more messages per minute.
  • C Enhanced scaling, supporting thousands more devices per network segment than SNMPv2.
  • D Using a push model instead of pull. SNMPv3 uses telemetry to push data to SNMP management stations in real time.
Explanation

SNMPv3 provides substantially stronger security through authentication, integrity protection, access control, and optional privacy (encryption) for SNMP messages. Its User-based Security Model defines authentication and encryption mechanisms, unlike SNMPv2's community-string-based security.
