Discuss Microsoft AZ-400 Exam Topic 5 Question 38

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?

ACreate an Azure Application Insights availability test and alert.

BCreate an Azure Service Health alert for the specific regions.

CCreate an Azure Monitor Availability metric and alert

DWrite an Azure function and deploy the function to the specific regions.

Suggested Answer: A

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.

Totally agree with A, super easy to set up!

Wait, D requires writing code? That seems like overkill!

C sounds good, but isn't it more complex?

I think B might be more suitable for regional issues.

A is the best option for quick alerts!

Writing an Azure function sounds like it could work, but it feels like it would take more time than just setting up an availability test.

I practiced a similar question where we had to set up monitoring, and I think using Azure Monitor metrics could be a viable option too.

I remember we discussed Application Insights in class, and it seems like a good fit for monitoring availability.

I'm not entirely sure, but I think Service Health alerts are more for infrastructure issues rather than specific app availability.

I'm a bit confused by this question. I know SonarQube is a code quality tool, but I'm not sure how the different build tools like Chef, Gradle, Octopus, and Gulp would integrate with it. I'll have to review my notes on build automation and code analysis tools to figure this out.

Hmm, I'm a bit unsure about this one. The question mentions John being responsible for the SOC, but doesn't explicitly state his job title. I'll have to think through the different options carefully before selecting an answer.

Wait, do I need to set the "Number of occurrences by period" field to 3 since it's a quarterly accrual? Or should I leave it at whatever the monthly/annual settings are?
