B. HDInsight Apache storm cluster
C. Azure stream Analytics
D. HDInsight Spark cluster

Show Suggested Answer

Suggested Answer: B 🗳️
All of these features are provided with the HDInsight Apache Storm cluster. The Microsoft documentation mentions the following:
Why use Apache Storm on HDInsight?
Storm on HDInsight provides the following features:
ג€¢ 99% Service Level Agreement (SLA) on Storm uptime: For more information, see the SLA information for HDInsight document.
ג€¢ Supports easy customization by running scripts against a Storm cluster during or after creation. For more information, see Customize HDInsight clusters using script action.
ג€¢ Create solutions in multiple languages: You can write Storm components in the language of your choice, such as Java, C#, and Python.
- Integrates Visual Studio with HDInsight for the development, management, and monitoring of C# topologies. For more information, see Develop C# Storm topologies with the HDInsight Tools for Visual Studio.
- Supports the Trident Java interface. You can create Storm topologies that support exactly once processing of messages, transactional datastore persistence, and a set of common stream analytics operations.
ג€¢ Dynamic scaling: You can add or remove worker nodes with no impact to running Storm topologies.
- You must deactivate and reactivate running topologies to take advantage of new nodes added through scaling operations.
ג€¢ Create streaming pipelines using multiple Azure services: Storm on HDInsight integrates with other Azure services such as Event Hubs, SQL Database, Azure
Storage, and Azure Data Lake Storage.
All of the other options are incorrect because they don't provide all of the capabilities.
