Question: In a Telecom Management Scenario, what triggers a MnS (Management and Network Services) producer to send a notification to subscribed MnS consumers regarding a 'ThresholdMonitor'?
Option 1: Scheduled Reporting Interval Expiration
Option 2: Detection of Threshold Crossing for a Monitored Performance Metric by the ThresholdMonitor
Option 3: Manual Request from an Authorized MnS Consumer
Option 4: Failure of Heartbeat Signal from MnS Producer to Consumers
Explanation: The correct answer is Option 2 because, as per telecom management principles, a 'ThresholdMonitor' is specifically designed to track and identify when a monitored performance metric exceeds or crosses a predefined threshold. This event-driven approach ensures timely notifications are sent to interested parties (subscribed MnS consumers) without unnecessary periodic updates, thus optimizing network resource utilization and focusing attention on critical changes in network performance.
