Which system executes an agent that reports information back to a central manager?

1. WMI

2. SMTP

3. SMS

4. SNMP

The correct answer is: SNMP

The correct answer is based on the role of the Simple Network Management Protocol (SNMP), which is specifically designed for network management. SNMP operates by allowing network devices to communicate with a central management application. The 'agent' in this context refers to a software component that runs on the managed devices and collects various types of information, such as performance metrics and status data. Once this agent gathers data, it sends the information back to the central manager using SNMP traps or polls. This mechanism enables network administrators to monitoring and manage a wide range of devices from different manufacturers through a standardized framework. The capability of SNMP to effectively summarize and relay status information helps ensure that any issues can be promptly identified and addressed, contributing to improved network reliability. In contrast, the other choices represent different protocols or tools that serve different purposes. WMI (Windows Management Instrumentation) is used for managing and monitoring Windows-based systems, but it does not operate in the same standardized way across various network devices as SNMP does. SMTP (Simple Mail Transfer Protocol) is focused on sending emails, while SMS (Short Message Service) is for text messaging. Neither of these options has the ability to execute agents that report system performance or status back to a central manager like SN
