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

Explanation:
Box 1: readinessProbe: For containerized applications that serve traffic, you might want to verify that your container is ready to handle incoming requests. Azure Container Instances supports readiness probes to include configurations so that your container can't be accessed under certain conditions.    Incorrect Answers: livenessProbe: Containerized applications may run for extended periods of time, resulting in broken states that may need to be repaired by restarting the container. Azure Container Instances supports liveness probes so that you can configure your containers within your container group to restart if critical functionality is not working.  Box 2: periodSeconds: 15 The periodSeconds property designates the readiness command should execute every 15 seconds.    Reference: https://docs.microsoft.com/en-us/azure/container-instances/container-instances-readiness-probe

Question 5
You have a Microsoft ASP.NET Core web app in Azure that is accessed worldwide.    
You need to run a URL ping test once every five minutes and create an alert when the web app is unavailable from specific Azure regions. The solution must minimize development time.    
What should you do?
  1. Create an Azure Monitor Availability metric and alert.
  2. Create an Azure Application Insights availability test and alert.
  3. Write an Azure function and deploy the function to the specific regions.
  4. Create an Azure Service Health alert for the specific regions.
Correct answer: B
Explanation:
There are three types of Application Insights availability tests: URL ping test: a simple test that you can create in the Azure portal. Multi-step web test  Custom Track Availability Tests    Note: After you've deployed your web app/website, you can set up recurring tests to monitor availability and responsiveness. Azure Application Insights sends web requests to your application at regular intervals from points around the world. It can alert you if your application isn't responding, or if it responds too slowly.    You can set up availability tests for any HTTP or HTTPS endpoint that is accessible from the public internet. You don't have to make any changes to the website you're testing. In fact, it doesn't even have to be a site you own. You can test the availability of a REST API that your service depends on.    Reference: https://docs.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability#create-a-url-ping-test
