What is the difference between auto-discovery and manual device addition in NPM?

• A. Manual add is automatic and requires no credentials.
• B. Auto-discovery connects devices via SSH only.
• C. Auto-discovery detects devices automatically based on scanning ranges; manual add lets you specify exact IPs, credentials, and polling options.
• D. Auto-discovery only works with SNMPv3.

Answer: (C)

Auto-discovery vs manual device addition in NPM centers on how devices get into monitoring: one method scans the network to find devices on its own, while the other requires you to specify each device and its details. Auto-discovery scans ranges you define, detects devices that answer on supported protocols, and then adds them to monitoring with appropriate default settings. This is convenient for growing networks because it reduces manual entry and helps you quickly populate a large inventory. It can determine device type or vendor and apply general polling configurations based on what it finds. Manual addition is a precise, hands-on approach. You pick the exact IP addresses to monitor and supply the necessary details—credentials, protocol choices (like SNMP versions, WMI, SSH), and specific polling options or schedules. This gives you complete control, which is useful for devices outside the discovery scope, devices with special credentials, or when you want to tailor monitoring on a per-device basis. Why the other statements don’t fit: manual addition is not automatic and does require credentials you provide; auto-discovery isn’t limited to SSH—discovery can use multiple protocols such as SNMP, ICMP, SSH, or WMI depending on the device; and auto-discovery is not restricted to SNMPv3, as it typically supports various SNMP versions or other discovery methods.
