QUESTION 104
You have a MongoDB database that you plan to migrate to an Azure Cosmos DB account that uses the MongoDB API. During testing, you discover that the migration takes longer than expected.
You need to recommend a solution that will reduce the amount of time it takes to migrate the data.
What are two possible recommendations to achieve this goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.
A. Increase the Request Units (RUs).
B. Turn off indexing.
C. Add a write region.
D. Create unique indexes.
E. Create compound indexes.
Correct Answer: AB
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.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You plan to store delimited text files in an Azure Data Lake Storage account that will be organized into department folders. You need to configure data access so that users see only the files in their respective department folder.
Solution: From the storage account, you enable a hierarchical namespace, and you use RBAC. Does this meet the goal?
A. Yes
B. No
Correct Answer: B
Explanation:
Disable the hierarchical namespace. And 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.

QUESTION 112
You are designing a data storage solution for a database that is expected to grow to 50 TB. The usage pattern is singleton inserts, singleton updates, and reporting.
Which storage solution should you use?
A. Azure SQL. Database elastic pools
B. Azure SQL Data Warehouse
C. Azure Cosmos DB that uses the Gremlin API
D. Azure SQL Database Hyperscale
Correct Answer: D
Explanation:
A Hyperscale database is an Azure SQL database in the Hyperscale service tier that is backed by the Hyperscale scale-out storage technology. A Hyperscale database supports up to 100 TB of data and provides high throughput and performance, as well as rapid scaling to adapt to the workload requirements. Scaling is transparent to the application connectivity, query processing, etc. work like any other Azure SQL database.
Incorrect Answers:
A: SQL Database elastic pools are a simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands. The databases in an elastic pool are on a single Azure SQL Database server and share a set number of resources at a set price. Elastic pools in Azure SQL Database enable SaaS developers to optimize the price performance for a group of databases within a prescribed budget while delivering performance elasticity for each database.
B: Rather than SQL Data Warehouse, consider other options for operational (OLTP) workloads that have large numbers of singleton selects. References:

QUESTION 113
A company plans to use Apache Spark Analytics to analyze intrusion detection data
You need to recommend a solution to monitor network and system activities for malicious activities and policy violations. Reports must be produced in an electronic format and sent to management. The solution must minimize administrative efforts.
What should you recommend?
A. Azure Data Factory
B. Azure Data Lake
C. Azure Databricks
D. Azure HDInsight
Correct Answer: D
Explanation:
With Azure HDInsight you can set up Azure Monitor alerts that will trigger when the value of a metric or the results of a query meet certain conditions. You can condition on a query returning a record with a value that is greater than or less than a certain threshold, or even on the number of results returned by a query. For example, you could create an alert to send an email if a Spark job fails or if a Kafka disk usage becomes over 90 percent full.
