Explanation:
Azure Data Lake Storage implements an access control model that derives from HDFS, which in turn derives from the POSIX access control model.
Blob container ACLs does not support the hierarchical namespace, so it must be disabled.

정답:
Explanation:
Instead of RBAC use access control lists (ACLs). Note: Azure Data Lake Storage implements an access control model that derives from HDFS, which in turn derives from the POSIX access control model.
Blob container ACLs does not support the hierarchical namespace, so it must be disabled.

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.

Explanation:
The Azure Cosmos DB Gremlin API can be used to store massive graphs with billions of vertices and edges.

정답:
Explanation:
Azure provides several solutions for working with CSV and JSON files, depending on your needs. The primary landing place for these files is either Azure Storage or Azure Data Lake Store.1
Azure Data Lake Storage is an optimized storage for big data analytics workloads.
Incorrect Answers:
D: Azure Blob Storage containers is a general purpose object store for a wide variety of storage scenarios. Blobs are stored in containers, which are similar to folders.

정답:
Explanation:
A: Increase the throughput during the migration by increasing the Request Units (RUs).
For customers that are migrating many collections within a database, it is strongly recommend to configure database-level throughput. You must make this choice when you create the database. The minimum database-level throughput capacity is 400 RU/sec. Each collection sharing database-level throughput requires at least 100 RU/sec.
B: By default, Azure Cosmos DB indexes all your data fields upon ingestion. You can modify the indexing policy in Azure Cosmos DB at any time. In fact, it is often recommended to turn off indexing when migrating data, and then turn it back on when the data is already in Cosmos DB.

정답:
Explanation:
Choose a partition key that has a wide range of values and access patterns that are evenly spread across logical partitions. This helps spread the data and the activity in your container across the set of logical partitions, so that resources for data storage and throughput can be distributed across the logical partitions.
Choose a partition key that spreads the workload evenly across all partitions and evenly over time. Your choice of partition key should balance the need for efficient partition queries and transactions against the goal of distributing items across multiple partitions to achieve scalability.
Candidates for partition keys might include properties that appear frequently as a filter in your queries. Queries can be efficiently routed by including the partition key in the filter predicate.

Explanation:
Log records: SQL
Social media mentions: Gremlin
You can store the actual graph of followers using Azure Cosmos DB Gremlin API to create vertexes for each user and edges that maintain the "A-follows-B" relationships. With the Gremlin API, you can get the followers of a certain user and create more complex queries to suggest people in common. If you add to the graph the Content Categories that people like or enjoy, you can start weaving experiences that include smart content discovery, suggesting content that those people you follow like, or finding people that you might have much in common with.

Explanation:
First week: Hot
Hot - Optimized for storing data that is accessed frequently.
After one month: Cool
Cool - Optimized for storing data that is infrequently accessed and stored for at least 30 days.
After one year: Cool
Incorrect Answers:
Archive: Optimized for storing data that is rarely accessed and stored for at least 180 days with flexible latency requirements (on the order of hours).

정답:
Explanation:
When you create a new server in Azure SQL Database or Azure Synapse Analytics named MySQL server, for example, a server-level firewall blocks all access to the public endpoint for the server (which is accessible at mysqlserver.database.windows.net).
Connection attempts from the internet and Azure must pass through the firewall before they reach your server or database, as the following diagram shows.
Incorrect Answers:
C: Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications.
D: A VPN gateway is a specific type of virtual network gateway that is used to send encrypted traffic between an Azure virtual network and an on-premises location over the public Internet.

Explanation:
Azure Files enables you to set up highly available network file shares that can be accessed by using the standard Server Message Block (SMB) protocol.
Incorrect Answers:
A: The Azure Queue service is used to store and retrieve messages. It is generally used to store lists of messages to be processed asynchronously.
C: Blob storage is optimized for storing massive amounts of unstructured data, such as text or binary data. Blob storage can be accessed via HTTP or HTTPS but not via SMB.
D: Azure Table storage is used to store large amounts of structured data. Azure tables are ideal for storing structured, non-relational data.
