DP-700 Implementing Data Engineering Solutions Using Microsoft Fabric Questions and Answers

You are developing a data pipeline named Pipeline1.

You need to add a Copy data activity that will copy data from a Snowflake data source to a Fabric warehouse.

What should you configure?

You have a KQL database that contains a table named Readings.

You need to build a KQL query to compare the Meter-Reading value of each row to the previous row base on the ilmestamp value

A sample of the expected output is shown in the following table.

You have a Fabric notebook named Notebook1 that has been executing successfully for the last week.

During the last run, Notebook1executed nine jobs.

You need to view the jobs in a timeline chart.

What should you use?

You have a Fabric workspace that contains a lakehouse named Lakehousel. Lakehousel contains a table named Status_Target that has the following columns:

• Key

• Status

• LastModified

The data source contains a table named Status.Source that has the same columns as Status_Target. Status.Source is used to populate Status_Target. In a notebook name Notebook!, you load Status_Source to a DataFrame named sourceDF and Status_Target to a DataFrame named targetDF. You need to implement an incremental loading pattern by using Notebook-!. The solution must meet the following requirements:

• For all the matching records that have the same value of key, update the value of LastModified in Status_Target to the value of LastModified in Status_Source.

• Insert all the records that exist in Status_Source that do NOT exist in Status_Target.

• Set the value of Status in Status_Target to inactive for all the records that were last modified more than seven days ago and that do NOT exist in Status.Source.

You are implementing a medallion architecture in a Fabric lakehouse.

You plan to create a dimension table that will contain the following columns:

• ID

• CustomerCode

• CustomerName

• CustomerAddress

• CustomerLocation

• ValidFrom

• ValidTo

You need to ensure that the table supports the analysis of historical sales data by customer location at the time of each sale Which type of slowly changing dimension (SCD) should you use?

You have a Fabric warehouse named DW1 that contains four staging tables named ProductCategory, ProductSubcategory, Product, and SalesOrder. ProductCategory, ProductSubcategory, and Product are used often in analytical queries.

You need to implement a star schema for DW1. The solution must minimize development effort.

Which design approach should you use? To answer, select the appropriate options in the answer area.

HOTSPOT

You have a Fabric workspace that contains an eventstream named EventStream1.

You discover that an EventStream1 transformation fails.

You need to find the following error information:

The error details, including the occurrence time

The total number of errors

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

NOTE: Each correct selection is worth one point.

You have an Azure key vault named KeyVaultl that contains secrets.

You have a Fabric workspace named Workspace-!. Workspace! contains a notebook named Notebookl that performs the following tasks:

• Loads stage data to the target tables in a lakehouse

• Triggers the refresh of a semantic model

You plan to add functionality to Notebookl that will use the Fabric API to monitor the semantic model refreshes. You need to retrieve the registered application ID and secret from KeyVaultl to generate the authentication token.

Solution: You use the following code segment:

Use notebookutils.credentials.getSecret and specify the key vault URL and key vault secret. Does this meet the goal?
