Which is a network management software typically used by network administrators when the network is lightly used?

The correct choice reflects a category of tools that network administrators utilize to ensure the functionality and integrity of network operations, particularly when the network is under lighter loads. Network traffic analyzers are specially designed to monitor and analyze data packets flowing through the network efficiently.

When the network is lightly used, these analyzers can provide granular insights into performance metrics, bandwidth use, and application behavior without the interference of heavy traffic. This makes it an optimal time for network admins to conduct detailed assessments, identify potential bottlenecks, and analyze patterns in user behavior or application performance without risking significant disruption.

In contrast, backup and recovery utilities primarily focus on data protection rather than real-time network performance monitoring. Their function is typically invoked during specific events such as data loss or corruption, rather than as ongoing operational tools under normal conditions. Therefore, they would not be the most suitable choice for lightly used network situations aimed at performance monitoring and proactive management.
