What is the role of the Simple Network Management Protocol (SNMP)?

The Simple Network Management Protocol (SNMP) plays a crucial role in network management by allowing administrators to monitor and collect data from networked devices, such as routers, switches, and cameras. It provides a standardized framework for managing devices on IP networks, enabling the retrieval of health information such as device performance, operational status, and error rates. This information is vital for ensuring the reliability and efficiency of network operations, as it helps in identifying and troubleshooting issues proactively.

In contrast, the other options detail functions not associated with SNMP. Dividing networks into subnets relates to IP address planning and management, enabling more efficient routing and reducing broadcast traffic. Enabling secure remote connections is typically handled by protocols such as SSH or VPNs rather than SNMP. Finally, assigning IP addresses within a LAN is managed through protocols like DHCP, which automates the process of assigning IP addresses to devices on the network. Thus, the primary function of SNMP is centered on monitoring and collecting crucial health data from network devices, making it an essential tool for network administrators.
