Question: What is the expected outcome for `thresholdMonitorStatus` when a successful `suspendThresholdMonitor` ACTION is executed on a Threshold Monitor in a Telecommunication Management system?
Option 1:  `thresholdMonitorStatus` remains unchanged.
Option 2: `thresholdMonitorStatus` is set to Active.
Option 3: `thresholdMonitorStatus` is deleted from the system.
Option 4: `thresholdMonitorStatus` is set to Suspended.
Explanation: According to the behavior defined for the `suspendThresholdMonitor` ACTION, upon successful execution, the `thresholdMonitorStatus` associated with the targeted Threshold Monitor is specifically updated to indicate a state of suspension. This update to 'Suspended' signifies that while the Threshold Monitor itself continues to exist within the system, its monitoring and alarm emission functions are temporarily halted until further action is taken (e.g., resumption).
