Exam DP-200 topic 4 question 12 discussion

Actual exam question from Microsoft's DP-200

Question #: 12
Topic #: 4

Your company uses several Azure HDInsight clusters.
The data engineering team reports several errors with some applications using these clusters.
You need to recommend a solution to review the health of the clusters.
What should you include in your recommendation?

A. Azure Automation
B. Log Analytics
C. Application Insights

Show Suggested Answer

Suggested Answer: B 🗳️
Azure Monitor logs integration. Azure Monitor logs enables data generated by multiple resources such as HDInsight clusters, to be collected and aggregated in one place to achieve a unified monitoring experience.
As a prerequisite, you will need a Log Analytics Workspace to store the collected data. If you have not already created one, you can follow the instructions for creating a Log Analytics Workspace.
You can then easily configure an HDInsight cluster to send many workload-specific metrics to Log Analytics.

In a real world scenario, using App Insights would be highly recommended in addition to Azure Monitor for correct error diagnosis. Since the question points to "review health of clusters" Azure Monitor should be the correct one.

I don't think so. Application Insights is used to monitor applications. "Application Insights, a feature of Azure Monitor, is an extensible Application Performance Management (APM) service for developers and DevOps professionals. Use it to monitor your live applications. It will automatically detect performance anomalies, and includes powerful analytics tools to help you diagnose issues and to understand what users actually do with your app. It's designed to help you continuously improve performance and usability." The question is about the health of the clusters. For this you can use Azure Monitor, for which you need a Log Analytics Workspace, like in the explanation.
