Which statement best describes the SNMP agent's role on network devices?

• A. It collects logs and writes to disk
• B. It filters traffic
• C. It authenticates users for SNMP
• D. It sends data to a central Network Management System

Answer: (D)

The core idea is how SNMP components enable centralized monitoring. An SNMP agent runs on each network device and stores management information in the MIB. Its main job is to provide that data to a central Network Management System (the SNMP manager) when asked, so the NMS can monitor device health, performance, and status. The agent can also send alerts (traps) when something noteworthy happens, but the essential role is supplying data to the central manager. The other options describe functions that aren’t the agent’s primary purpose: logging to disk, traffic filtering, or user authentication for SNMP are outside its main role of exposing device data to the NMS.
