• Question 51:

  A data architect plans to build an app that contains geographically diverse data that must be specific to user run-time selections. The source contains transactional data. The app must have minimal impact on already limited server resources.

  Which approach should the data architect use?

  A. Loop and Reduce

  B. QVDs

  C. In-memory

  D. ODAG

  Correct Answer: B

  Explanation: Using QVDs is the best approach for this scenario, as it allows the data to be stored in a highly compressed format, which will have minimal impact on server resources. Additionally, QVDs can be loaded quickly, which allows for faster access to the data based on user run-time selections. The other options, Loop and Reduce, In-memory, and ODAG, are not valid strategies for this scenario.

• Question 52:

  A data architect of an organization that has implemented Qlik Sense on Windows needs to load large amounts of data from a database that is continuously updated

  New records are added, and existing records get updated and deleted. Each record has a LastModified field.

  All existing records are exported into a QVD file. The data architect wants to load the records into Qlik Sense efficiently.

  Which steps should the data architect take to meet these requirements?

  A. 1 Load the existing data from the QVD

  2.

  Load the new and updated data from the database without the rows that have just been loaded from the QVD and concatenate with data from the QVD

  3.

  Load all records from the key field from the database and use an INNER JOIN on the previous table

  B. 1. Load the existing data from the QVD

  2.

  Load new and updated data from the database Concatenate with the table loaded from the QVD.

  3.

  Create a separate table for the deleted rows and use a WHERE NOT EXISTS to remove these records

  C. 1. Use a partial LOAD to load new and updated data from the database.

  2.

  Load the existing data from the QVD without the updated rows that have just been loaded from the database and concatenate with the new and updated records

  3.

  Use the PEEK function to remove the deleted rows

  D. 1 Load the new and updated data from the database.

  2.

  Load the existing data from the QVD without the updated rows that have just been loaded from the database and concatenate with the new and updated records.

  3.

  Load all records from the key field from the database and use an INNER JOIN on the previous table.

  Correct Answer: D

  B. Create a composite key using OrdertD and LineNo

  C. Remove the LineNo field from both tables and use the AutoNumber function on the OrderlC field

  D. Create a composite key using OrderlD and LineNo. and remove OrderlD and LineNo from Shipments

• Question 55:

  D. Option D

  Correct Answer: C

• Question 56:

  A. Option A

  B. Option B

  C. Option C

• Question 57:

  Users of a published app report incomplete visualizations. The data architect checks the app multiple times and cannot replicate the error. The error affects only one team. What is the most likely cause?

  A. An Omit field has been applied

  B. Section access restricts too many records

  C. A security rule has been applied to the sheet object

  D. The affected users were NOT added to the Section table

  Correct Answer: B

  Explanation: Section access restricts access to certain records, and if too many records are restricted, it can lead to incomplete visualizations.Source: Qlik Section access is used to control access to the data in an app. If the section access settings are too restrictive, they can prevent certain users or teams from seeing all of the data they need, resulting in incomplete visualizations. It is possible that the affected team has been assigned a section access that is too restrictive, preventing them from seeing all of the necessary data. This could be a misconfiguration or an oversight in the section access settings.

• Question 58:

  

  A data architect is creating an app using three tables. After executing the script, a warning displays Which two steps should the data architect do to resolve this warning? (Select two.)

  A. Remove the rename statement (line 24) in the ProductPriceList table leaving the Product field name as is.

  B. Rename the Category field in the ProductPriceLis table to PnceCategory (line 24).

  C. Move the preceding Load statement in line 10 between table name (line 23) and Load statement (line 24).

  D. insert "Join (ProductDetails)" in front of the Load statement in line 24 to combine ProductPriceList with ProductDetails

  Correct Answer: B

• Question 59:

  

  A Human Resources Director needs an app to analyze organizational structure. The Directory is particularly interested in the longest levels of line management. Two table loads are required. Both use the same basic structure.

  

  Which two table load prefixes are needed?

  Correct Answer: D

• Question 60:

  A data architect needs to upload data from ten different sources, but only if there are any changes after the last reload When data is updated, a new file is placed into a folder mapped to E A439926003 The data connection points to this folder.

  The data architect plans a script which will:

  1.

  Verify that the file exists

  2.

  If the file exists, upload it Otherwise, skip to the next piece of code

  The script will repeat this subroutine for each source. When the script ends, all uploaded files will be removed with a batch procedure.

  Which option should the data architect use to meet these requirements?
