How does data collection differ between SNMP polling and WMI on Windows hosts in NPM?

• A. WMI provides deeper Windows-specific metrics, while SNMP polls standard OIDs for performance data.
• B. SNMP polling provides deeper Windows-specific metrics.
• C. WMI is used only for network devices, not Windows hosts.
• D. SNMP polling collects all metrics with no overhead on Windows hosts.

Answer: (A)

On Windows hosts, the way data is collected determines how deep the metrics go. WMI taps into Windows Management Instrumentation, giving access to rich, Windows-specific data such as per‑process counters, detailed memory and page file information, service status, event logs, registry data, and a wide range of Windows performance counters. SNMP, by contrast, relies on standard MIBs and OIDs that describe generic performance data across devices, so the metrics are broad and cross‑device but typically not as granular or Windows‑specific. So, the best answer captures that WMI provides deeper Windows-specific metrics, while SNMP polls standard OIDs for general performance data. The other statements don’t fit: SNMP isn’t able to match the Windows-centric depth of WMI, WMI is not limited to network devices, and SNMP polling on Windows isn’t without any overhead.
