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

Answer(s): A,B

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.

HOTSPOT (Drag and Drop is not supported)
You have an Azure Kubernetes Service (AKS) pod.
You need to configure a probe to perform the following actions:

Confirm that the pod is responding to service requests. Check the status of the pod four times a minute.
Initiate a shutdown if the pod is unresponsive.

How should you complete the YAML configuration file? To answer, select the appropriate options in the answer area.

Hot Area:

  1. See Explanation section for answer.

Answer(s): A

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.

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.

Answer(s): 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



You have a multi-tier application. The front end of the application is hosted in Azure App Service. You need to identify the average load times of the application pages.
What should you use?

  1. Azure Application Insights
  2. the activity log of the App Service
  3. the diagnostics logs of the App Service
  4. Azure Advisor

Answer(s): A

Explanation:

Application Insights will tell you about any performance issues and exceptions, and help you find and diagnose the root causes.

Application Insights can monitor both Java and ASP.NET web applications and services, WCF services. They can be hosted on-premises, on virtual machines, or as Microsoft Azure websites.

On the client side, Application Insights can take telemetry from web pages and a wide variety of devices including iOS, Android, and Windows Store apps.

the correct answer to q8 is b. explanation since the mule app has a dependency, it is necessary to include project modules and dependencies to make sure the app will run successfully on the runtime on any other machine. source code of the component that the mule app is dependent of does not need to be included in the exported jar file, because the source code is not being used while executing an app. compiled code is being used instead.
