A user needs to retrieve the active alarm list from a network element.

Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:

The Nokia 1830 PSS uses a Command Line Interface (CLI) that is distinct from the Nokia SR-OS used in routers. For technicians performing local maintenance or troubleshooting via a serial or SSH connection to theShelf Controller (EC), the command to view the current status of the network element's alarms isshow fault-databaseor the shorthandalm.

When the alm command is executed, the system displays a table containing all active alarms, their severity (Critical, Major, Minor, or Warning), the timestamp of the occurrence, and the specific object (e.g., a specific port or card) that is reporting the fault. This is the primary method for "Layer 0" local troubleshooting. While management software likeWS-NOCprovides a Graphical User Interface (GUI) to view these alarms, knowing the CLI command is essential for field operations where a connection to the central management system might not be available. Option B, C, and D are incorrect as they do not follow the specific syntax of the 1830 PSS CLI environment.
