Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which service is a Hadoop offering hosted in Azure for managing Hadoop clusters?

1. Data Lake Analytics

2. Azure HD Insight

3. CosmosDB

4. Azure Function

The correct answer is: Azure HD Insight

The correct answer is Azure HD Insight, as it is specifically designed to provide fully managed Apache Hadoop services within the Azure cloud platform. Azure HD Insight allows users to easily provision and manage Hadoop clusters for big data processing and analytics without the complexity of infrastructure maintenance. Azure HD Insight provides various features such as support for different Hadoop components like Spark, Hive, and Kafka, enabling organizations to run big data workloads efficiently. It abstracts many of the management tasks associated with running Hadoop clusters, allowing developers and data engineers to focus on their applications rather than on managing the underlying infrastructure. In contrast, Data Lake Analytics is a service primarily focused on data processing rather than hosting Hadoop clusters. Although it can work with data stored in Azure Data Lake, it doesn't provide the same extensive Hadoop capabilities. CosmosDB is a globally distributed database service that does not offer Hadoop functionalities. Lastly, Azure Functions is a serverless compute service designed for running event-driven code, which does not relate to Hadoop cluster management.
