Which alarm setting is configured to monitor serious events that affect, but do not shut down, the operation of a network function?

'Critical' alarms denote the most severe events, usually indicating a complete loss of service or function, or a catastrophic failure.

'Medium' (often categorized as 'Warning') alarms indicate a potential issue or threshold breach that may lead to service degradation if not addressed, but are less severe than 'Major'.

In network alarm severity classifications, a 'Major' alarm typically indicates a serious service-affecting event that requires immediate attention to restore full functionality or prevent further degradation. These events impact the operation of a network function but do not necessarily cause a complete outage.

'Minor' alarms are for non-service impacting events, such as informational messages or early warnings that require monitoring but no immediate action.
