Which device types can NPM monitor effectively with SNMP, and what implication does that have for credentials?

• A. Routers, switches, firewalls, servers; SNMP credentials must be valid for each OS vendor to gather accurate metrics
• B. Routers and switches only
• C. Servers only
• D. Firewalls and routers only

Answer: (A)

SNMP-based monitoring in NPM works across a wide range of devices, including routers, switches, firewalls, and servers. Each device runs an SNMP agent that exposes MIB data, and NPM uses SNMP credentials to authenticate and read those metrics. The key point is that different vendors and operating systems implement SNMP a bit differently, so credentials must be valid for each device’s vendor/OS to access the correct MIBs and gather accurate data. That’s why the best approach is to configure appropriate SNMP credentials for each device family (for example, Cisco gear versus Windows servers) rather than assuming one credential will work for all devices.
