Question 2
You manage an Azure web app that supports an e-commerce website.    
You need to increase the logging level when the web app exceeds normal usage patterns. The solution must minimize administrative overhead.  
Which two resources should you include in the solution? Each correct answer presents part of the solution.  
NOTE: Each correct selection is worth one point.
  1. an Azure Automation runbook
  2. an Azure Monitor alert that has a dynamic threshold
  3. an Azure Monitor alert that has a static threshold
  4. the Azure Monitor autoscale settings
  5. an Azure Monitor alert that uses an action group that has an email action
Correct answer: AB
Explanation:
B: Metric Alert with Dynamic Thresholds detection leverages advanced machine learning (ML) to learn metrics' historical behavior, identify patterns and anomalies that indicate possible service issues. It provides support of both a simple UI and operations at scale by allowing users to configure alert rules through the Azure Resource Manager API, in a fully automated manner.    A: You can use Azure Monitor to monitor base-level metrics and logs for most services in Azure. You can call Azure Automation runbooks by using action groups or by using classic alerts to automate tasks based on alerts.    Reference: https://docs.microsoft.com/en-us/azure/azure-monitor/platform/alerts-dynamic-thresholds   https://docs.microsoft.com/en-us/azure/automation/automation-create-alert-triggered-runbook
