In network monitoring, what does a software agent do?

1. Compresses data for transmission

2. Monitors performance and gathers data

3. Controls network switches

4. Secures the network from external threats

The correct answer is: Monitors performance and gathers data

A software agent is a component used in network monitoring that actively observes the performance of various devices and systems within a network. Its primary function involves collecting and reporting relevant metrics, such as bandwidth usage, latency, error rates, and device health. This data is crucial for network administrators to analyze how the network is performing, identify potential issues, and ensure that the network aligns with performance benchmarks. By continuously monitoring the network and gathering data, software agents play a significant role in maintaining optimal network performance. They help in proactive troubleshooting by sending alerts when certain thresholds are met or exceeded, allowing for timely interventions before issues affect end users. This role is essential for maintaining high levels of service availability and reliability in network management. The other options do not align with the primary function of a software agent; they pertain to different aspects of network operations. For instance, while data compression improves transmission efficiency, controlling network switches involves managing network traffic rather than monitoring. Securing the network focuses on threat prevention, which is distinct from the performance monitoring function. Thus, the role of the software agent is distinctly centered around performance monitoring and data gathering.
