What function does the SNMP manager serve?

The SNMP manager plays a crucial role in network management by monitoring network devices. It serves as an interface for system administrators to collect information from SNMP-enabled devices such as routers, switches, and servers. The SNMP manager can query these devices for performance metrics, status updates, and alarms, enabling administrators to have a real-time view of network health and performance.

By monitoring various parameters like CPU usage, memory utilization, and network traffic, the SNMP manager allows for effective management and troubleshooting of the network. It collects this information via Simple Network Management Protocol (SNMP) and can also receive notifications (traps) from devices when specific events occur, further enhancing its monitoring capabilities.

The other options, such as configuration of routers, domain name resolution, and data encryption, do not accurately depict the primary function of an SNMP manager. While SNMP can assist in configuration to some extent (such as changing settings through SNMP set commands), its primary role is focused on monitoring rather than direct configuration. Domain name resolution pertains to translating domain names into IP addresses and is handled by DNS, not an SNMP manager. Data encryption relates to securing data during transmission, which is not a function associated with SNMP managers. Thus, monitoring network devices is
