Exam DP-203 topic 3 question 12 discussion

A is the correct Answer. You can specify the number of partitions at the time of creating an event hub. In some scenarios, you may need to add partitions after the event hub has been created. This article describes how to dynamically add partitions to an existing event hub. Dynamic additions of partitions is available only in premium and dedicated tiers of Event Hubs. https://docs.microsoft.com/en-us/azure/event-hubs/dynamically-add-partitions

Answer is Correct according to given link

Answer is Correct

A. Azure Event Hubs Dedicated would be the best choice to ingest the variable volumes of data and change the partition count after creation. Azure Event Hubs Dedicated is a highly scalable and fully managed event hub service that can ingest millions of events per second. It allows you to create and manage partitions, and you can dynamically increase or decrease the number of partitions to accommodate changes in data volume or throughput requirements. Azure Stream Analytics, Azure Data Factory, and Azure Synapse Analytics are not specifically designed to manage the partition count after creation. Although they can be used to ingest streaming data, they may not provide the flexibility to change the partition count dynamically.

Correct

A is correct

As A is correct

From the provided link: "We recommend that you choose at least as many partitions as you expect that are required during the peak load of your application for that particular event hub. You can't change the partition count for an event hub after its creation except for the event hub in a dedicated cluster. The partition count for an event hub in a dedicated Event Hubs cluster can be increased after the event hub has been created, but the distribution of streams across partitions will change when it's done as the mapping of partition keys to partitions changes, so you should try hard to avoid such changes if the relative order of events matters in your application."
