What is the primary purpose of node polling in NPM?

• A. To gather performance metrics at regular intervals.
• B. To update device firmware automatically.
• C. To generate user reports automatically.
• D. To assign devices to user groups.

Answer: (A)

Node polling is the regular querying of network devices to collect performance data. By polling at defined intervals, NPM gathers metrics like CPU and memory usage, interface throughput, and error rates, feeding dashboards, graphs, and alerts with up-to-date information. This ongoing data collection lets you monitor the network's health, spot trends, and respond to potential issues before they become problems. Firmware updates, automatic reporting, and grouping devices are separate functions—polling focuses on obtaining the performance metrics that these monitoring features rely on.
