A

Simple Network Management Protocol (SNMP)
SNMP is an application layer protocol under the Transmission Control Protocol/Internet Protocol (TCP⁄IP) protocol suite. It’s a professional-grade and widely accepted protocol to maintain network elements. It’s used for exchanging and extracting management information shared between network devices such as switches, modems, WLAN controllers, and routers. The information gathered is used to monitor the performance of the network based on bandwidth utilization, status of the interface, latency, and CPU usage. Most network elements are bundled with SNMP agents for better communication with monitoring systems, however, they need to be configured before use. The role of SNMP agents is to respond to queries, carry out requests, and indicate the event has occurred on the host running the network resource.
