You need to store data by using Azure Table storage.
What should you create first?

  1. an Azure Cosmos DB instance
  2. a storage account
  3. a blob container
  4. a table

Answer(s): B

Explanation:

First create an Azure storage account, then use Table service in the Azure portal to create a table.
Note: An Azure storage account contains all of your Azure Storage data objects: blobs, files, queues, and tables.

You need to recommend a data store service that meets the following requirements:

-Native SQL API access
-Configurable indexes

What should you recommend?

  1. Azure Files
  2. Azure Blob storage
  3. Azure Table storage
  4. Azure Cosmos DB

Answer(s): D

Explanation:

Azure Cosmos DB comes with native Core (SQL) API support.
In Azure Cosmos DB, data is indexed following indexing policies that are defined for each container. The default indexing policy for newly created containers enforces range indexes for any string or number. This policy can be overridden with your own custom indexing policy.

To complete the sentence, select the appropriate option in the answer area.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




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. With a hierarchical namespace enabled, a storage account becomes capable of providing the scalability and cost-effectiveness of object storage, with file system semantics that are familiar to analytics engines and frameworks.
