What is the purpose of the Credentials Manager in NPM and what credential types does it store?

• A. Credentials Manager securely stores SNMP, WMI, SSH/CLI passwords, and OAuth tokens; it centralizes credential usage for discovery, polling, and remote actions.
• B. It stores only SNMP community strings.
• C. It stores user login credentials for Windows Workstations.
• D. It stores only SSL certificates.

Answer: (A)

Credentials Manager in NPM is where the system securely stores the credentials it uses to access devices during discovery, polling, and remote actions. The idea is to centralize and protect authentication so the monitors can authenticate to many devices without prompting users each time, while keeping the credentials encrypted and access-controlled. It supports multiple credential types, including SNMP credentials (both community strings and SNMPv3), WMI for Windows devices, SSH/CLI credentials for network gear and Linux/Unix hosts, and OAuth tokens for API-based or cloud integrations. This broad support lets a single platform authenticate across different protocols and platforms from one place, simplifying management and enhancing security. Narrow options—like storing only SNMP community strings, or only Windows login credentials, or only SSL certificates—don’t cover the range of access methods used by discovery and polling, making them insufficient for full device reachability and remote actions.
