Answer Options
A
Create an alert in Azure Security Center based on security events.

D
Configure an alert in Azure Monitor Metrics for the Web App resource.
Correct Answer
B: Set up a custom metric in Application Insights to monitor CPU usage and create an alert based on that metric.
Explanation
The correct answer is B because you can set up custom metrics in Application Insights to monitor CPU usage and create alerts based on these metrics. Option A is incorrect as it pertains to Azure Monitor Metrics instead of Application Insights. Option C is incorrect as it involves setting up an alert in Azure Security Center, which is not relevant for monitoring CPU usage. Option D is incorrect as it refers to setting up an alert in Azure Log Analytics, which is also not the appropriate tool for this specific scenario.
