What is SNMP used for?

• A. Monitoring and managing network devices and performance.
• B. Encrypting data.
• C. Web hosting.
• D. DNS resolution.

Answer: (A)

SNMP is used to monitor and manage network devices and performance. It enables a centralized management system to query devices for status and metrics, and it can also receive alerts when something important happens. Each device runs an SNMP agent that exposes a set of variables—the MIB—that describe things like interface utilization, uptime, and error counts. The manager can read these values or configure certain settings, using requests such as GET or GETNEXT, and devices can proactively send traps to notify administrators of notable events. Different versions exist, with SNMPv1 and SNMPv2c relying on simple community strings for access, while SNMPv3 adds stronger authentication and encryption. But at its core, SNMP’s purpose is to monitor and manage network devices and their performance, rather than encrypting data, hosting websites, or resolving DNS.
