You manage a solution that uses Azure HDInsight clusters. You need to implement a solution to monitor cluster performance and status. Which technology should you use?
Suggested Answer:E🗳️
Ambari is the recommended tool for monitoring utilization across the whole cluster. The Ambari dashboard shows easily glanceable widgets that display metrics such as CPU, network, YARN memory, and HDFS disk usage. The specific metrics shown depend on cluster type. The ג€Hostsג€ tab shows metrics for individual nodes so you can ensure the load on your cluster is evenly distributed. The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. Ambari provides an intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs.

The question is asking about ' Implement a Solution' - I think the answer is 'Ambari REST API'
Ambari Web UI is a Tool but not a Technology to implement the solution.
this exam dp-200 variation bellow justifies NOW the use of ambari web UI, in this case yes, this is the right answer.
A company has a Microsoft Azure HDInsight solution that uses different cluster types to process and analyze data. Operations are continuous.
Reports indicate slowdowns during a specific time window.
You need to determine a monitoring solution to track down the issue in the least amount of time.
What should you use?
A. Azure Log Analytics log search query
B. Ambari REST API
C. Azure Monitor Metrics
D. HDInsight .NET SDK
E. Azure Log Analytics alert rule query
Apache Ambari simplifies Hadoop management by providing an easy-to-use web UI. You can use Ambari to manage and monitor Hadoop clusters. Developers can integrate these capabilities into their applications by using the Ambari REST APIs.
I think Azure Log Analytics would be the answer.
ALA monitors the Performance and Availability of the clusters.
Whereas Ambari is used to Monitor the Health and Utilization for any given HDIsight Cluster.
Can anyone plz confirm the correct answer.

The recommended way to monitor workload information and logs on Azure HDInsight is using Azure Monitor logs.
One of the key benefits of Azure Monitor logs is that you can push metrics and logs from multiple HDInsight clusters to the same Log Analytics workspace, allowing you to monitor multiple clusters in one place.
