A Copilot Studio agent at Pacific Airlines is connected to Azure Application Insights. The operations team has created an Azure Monitor alert rule that fires when the API error rate exceeds 5% in any 15-minute window. The alert fires, but no one receives a notification. What is most likely misconfigured?
Select an answer to reveal the explanation.
Short Explanation and Infographic
An Azure Monitor alert that fires silently is like a smoke alarm with no speaker — the detection works, but the notification is disconnected. Action Groups are the 'speaker' that routes alerts to email, Teams, or PagerDuty. The correct answer is B.

Full Explanation
## Why B is Correct Azure Monitor alert rules have two components: the alert condition (what to detect) and the action group (what to do when the alert fires). An action group defines notification channels: email addresses, SMS, Azure app push notifications, webhook URLs, and Teams channels. If no action group is attached to the alert rule, the alert fires and changes state in Azure Monitor but sends no notifications. This is the most common misconfiguration for 'alert fires but nobody knows.'
## Why the Distractors Are Wrong A (Threshold too low): The question states the alert fires, which means the condition and threshold are working correctly. The issue is with notification delivery, not detection.
C (App Insights not connected): The question states the alert fires — this confirms that telemetry is reaching Application Insights and the alert rule is evaluating it correctly. The problem is downstream in the notification chain.
D (24-hour warm-up period): There is no 24-hour warm-up requirement for Azure Monitor alert notifications. Notifications are delivered within minutes of an alert firing (subject to normal Azure service latency).
## Exam Tip Azure Monitor alert components: Alert Rule (condition + scope) + Action Group (notification channels + actions). Missing action group = silent alerts. Know this two-part structure for exam scenarios about alert misconfiguration.
