You configure Azure Application Insights and the shared service plan tier for a web app.
You enable Smart Detection.
You confirm that standard metrics are visible in the logs, but when you test a failure, you do not receive a Smart Detection notification.
What prevents the Smart Detection notification from being sent?

A. B. C. D.B
After setting up Application Insights for your project, and if your app generates a certain minimum amount of data, Smart Detection of failure anomalies takes 24 hours to learn the normal behavior of your app, before it is switched on and can send alerts.
https://docs.microsoft.com/en-us/azure/azure-monitor/app/proactive-failure-diagnosticsThe correct answer is B. Smart Detection uses the first 24 hours to establish the normal behavior of the web app.
Smart Detection is a feature of Azure Application Insights that provides intelligent insights and automatic anomaly detection for your web apps. It uses machine learning algorithms to analyze metrics and logs to detect issues and alert you when something is not working as expected.
When you enable Smart Detection for a web app, it takes about 24 hours for the feature to establish a baseline for the app's behavior. During this time, Smart Detection is collecting data and learning what is normal for the app. Once the baseline is established, Smart Detection will start alerting you when it detects anomalies or issues that are outside of the norm.
Therefore, if you test a failure during the first 24 hours after enabling Smart Detection, you may not receive a notification because the feature is still learning what is normal behavior for the app. After the baseline is established, Smart Detection will be able to detect anomalies and send notifications.
Option A is incorrect because the Snapshot Debugger is not required for Smart Detection to work. The Snapshot Debugger is a separate feature that allows you to take snapshots of your application at runtime to diagnose issues.
Option C is incorrect because the shared service plan tier does not prevent Smart Detection from sending notifications.
Option D is incorrect because restarting the web app does not enable Smart Detection. Smart Detection is automatically enabled once it is configured in the Azure portal.
