Which storage solution should you use?

You are designing a big data storage solution.

The solution must meet the following requirements:

– Provide unlimited account sizes.

– Support a hierarchical file system.

– Be optimized for parallel analytics workloads.

Which storage solution should you use?
A . Azure Data Lake Storage Gen2
B . Azure Blob storage
C . Apache HBase in Azure HDInsight
D . Azure Cosmos DB

Answer: A

Explanation:

Azure Data Lake Storage is optimized performance for parallel analytics workloads

A key mechanism that allows Azure Data Lake Storage Gen2 to provide file system performance at object storage scale and prices is the addition of a hierarchical namespace. This allows the collection of objects/ files within an account to be organized into a hierarchy of directories and nested subdirectories in the same way that the file system on your computer is organized.
