Question 66

You have an Azure Synapse Analytics dedicated SQL pool named Pool1 and an Azure Data Lake Storage Gen2 account named Account1.
You plan to access the files in Account1 by using an external table.
You need to create a data source in Pool1 that you can reference when you create the external table.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.

Question 67

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
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 create an Azure Databricks workspace that has a tiered structure. The workspace will contain the following three workloads:
A workload for data engineers who will use Python and SQL.
A workload for jobs that will run notebooks that use Python, Scala, and SOL.
A workload that data scientists will use to perform ad hoc analysis in Scala and R.
The enterprise architecture team at your company identifies the following standards for Databricks environments:
The data engineers must share a cluster.
The job cluster will be managed by using a request process whereby data scientists and data engineers provide packaged notebooks for deployment to the cluster.
All the data scientists must be assigned their own cluster that terminates automatically after 120 minutes of inactivity. Currently, there are three data scientists.
You need to create the Databricks clusters for the workloads.
Solution: You create a Standard cluster for each data scientist, a High Concurrency cluster for the data engineers, and a Standard cluster for the jobs.
Does this meet the goal?
  • Question 68

    You have an on-premises data warehouse that includes the following fact tables. Both tables have the following columns: DateKey, ProductKey, RegionKey. There are 120 unique product keys and 65 unique region keys.

    Queries that use the data warehouse take a long time to complete.
    You plan to migrate the solution to use Azure Synapse Analytics. You need to ensure that the Azure-based solution optimizes query performance and minimizes processing skew.

    Question 69

    You have a Microsoft SQL Server database that uses a third normal form schema.
    You plan to migrate the data in the database to a star schema in an Azure Synapse Analytics dedicated SQI pool.
    You need to design the dimension tables. The solution must optimize read operations.
    What should you include in the solution? to answer, select the appropriate options in the answer area.

    Question 70

    You are planning the deployment of Azure Data Lake Storage Gen2.
    You have the following two reports that will access the data lake:
    Report1: Reads three columns from a file that contains 50 columns.
    Report2: Queries a single record based on a timestamp.
    You need to recommend in which format to store the data in the data lake to support the reports. The solution must minimize read times.
    What should you recommend for each report? To answer, select the appropriate options in the answer are a.
