Which of the following is NOT a function of SNMP?

The correct answer identifies that backing up system configurations is not a function of SNMP (Simple Network Management Protocol). SNMP primarily focuses on network management and monitoring tasks. Its main functions involve gathering network statistics to assess performance, monitoring device performance to ensure devices are functioning correctly, and providing the capability to change device configurations remotely as part of managing and optimizing network resources.

While SNMP can provide access to device configurations so that administrators can make changes, it does not inherently include functions for creating backups of those configurations. Backup typically requires separate utilities or procedures specific to the operating systems or devices in use. Thus, the role of SNMP is centered on real-time management rather than on backup processes, which is why backing up system configurations is not a true function of SNMP.
