DP-203 Online Practice Questions and Answers

Questions 1

HOTSPOT

You have an Azure Synapse Analytics dedicated SQL pool named Pool1 that contains an external table named Sales. Sales contains sales data. Each row in Sales contains data on a single sale, including the name of the salesperson.

You need to implement row-level security (RLS). The solution must ensure that the salespeople can access only their respective sales.

What should you do? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Hot Area:

Show Answer

Correct Answer:

Box 1: A security policy for sale

Here are the steps to create a security policy for Sales:

Create a user-defined function that returns the name of the current user:

CREATE FUNCTION dbo.GetCurrentUser()

RETURNS NVARCHAR(128)

AS

BEGIN

RETURN SUSER_SNAME();

END;

Create a security predicate function that filters the Sales table based on the

current user:

CREATE FUNCTION dbo.SalesPredicate(@salesperson NVARCHAR(128)) RETURNS TABLE

WITH SCHEMABINDING

AS

RETURN SELECT 1 AS access_result

WHERE @salesperson = SalespersonName;

Create a security policy on the Sales table that uses the SalesPredicate function to filter the data:

CREATE SECURITY POLICY SalesFilter

ADD FILTER PREDICATE dbo.SalesPredicate(dbo.GetCurrentUser()) ON dbo.Sales

WITH (STATE = ON);

By creating a security policy for the Sales table, you ensure that each salesperson can only access their own sales data. The security policy uses a user-defined function to get the name of the current user and a security predicate function to

filter the Sales table based on the current user.

Box 2: table-value function

to restrict row access by using row-level security, you need to create a table-valued function that returns a table of values that represent the rows that a user can access. You then use this function in a security policy that applies a predicate on

the table.

Questions 2

You are designing an Azure Databricks interactive cluster. The cluster will be used infrequently and will be configured for auto-termination. You need to use that the cluster configuration is retained indefinitely after the cluster is terminated. The solution must minimize costs. What should you do?

A. Pin the cluster.

B. Create an Azure runbook that starts the cluster every 90 days.

C. Terminate the cluster manually when processing completes.

D. Clone the cluster after it is terminated.

Show Answer

Correct Answer: A

Azure Databricks retains cluster configuration information for up to 70 all-purpose clusters terminated in the last 30 days and up to 30 job clusters recently terminated by the job scheduler. To keep an all-purpose cluster configuration even after it has been terminated for more than 30 days, an administrator can pin a cluster to the cluster list.

Questions 3

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 have an Azure Storage account that contains 100 GB of files. The files contain rows of text and numerical values. 75% of the rows contain description data that has an average length of 1.1 MB.

You plan to copy the data from the storage account to an enterprise data warehouse in Azure Synapse Analytics.

You need to prepare the files to ensure that the data copies quickly.

Solution: You copy the files to a table that has a columnstore index.

Does this meet the goal?

A. Yes

B. No

Show Answer More Questions

Correct Answer: B

Instead convert the files to compressed delimited text files.
