Exam DP-200 topic 6 question 108 discussion

You have to deploy resources on Azure HDInsight for a batch processing job. The batch processing must run daily and must scale to minimize costs. You also be able to monitor cluster performance.
You need to decide on a tool that will monitor the clusters and provide information on suggestions on how to scale.
You decide on monitoring the cluster load by using the Ambari Web UI.
Would this fulfill the requirement?

Suggested Answer: A 🗳️
Yes, this will give you a good idea on the load on the Azure HDInsight cluster.
The Microsoft documentation mentions the following:

Monitor cluster load -
Hadoop clusters can deliver the most optimal performance when the load on cluster is evenly distributed across all the nodes. This enables the processing tasks to run without being constrained by RAM, CPU, or disk resources on individual nodes.
To get a high-level look at the nodes of your cluster and their loading, sign in to the Ambari Web UI, then select the Hosts tab. Your hosts are listed by their fully qualified domain names. Each host's operating status is shown by a colored health indicator:
