Qlik Sense Data Architect Certification Exam - February 2021 Release Sample Questions (Q21-Q26):
NEW QUESTION # 21
A data architect needs to create an app that combines employee data from the Sales system and the Human Resources (HR) system.
These systems identify employees differently Employees in the HR system are identified with an alpha-numeric key Employees in the Sales system are identified using an integer key.
The Human Resources manager creates a table that maps these keys to another, called Associations.
The resultant data model must meet the following requirements:
* Associations must be valid
* The model must be optimized for performance
* The option must support multiple tables added
Which solution should the data architect use to meet these requirements?
- A. MAPSUBSTRING ( 'Associations' ,EMployeekey) As Employeekey;
- B. RENAME FIELDS USING Associations;
- C. MAP EmloyeeKey USING Associations;
- D. APPLYMAP ( 'Associations , EmployeeKey ) as Employeekey;
Answer: C
Explanation:
The MAP function maps the EmployeeKey in the Sales system to the EmployeeKey in the HR system using the Associations table. This allows the data architect to join the data from the Sales system and the HR system using the same key, ensuring that the associations are valid.
Using the MAP function also optimizes the performance of the data model as it eliminates the need for multiple joins between the data from the Sales and HR systems.
This solution also supports multiple tables added, as the MAP function can be applied to any table that needs to be joined with the HR system data.
NEW QUESTION # 22

- B. Left Join between tables and Description xlsx in every Department table
- C. ApplyMap with two parameters after the Mapping load
- D. Enter "Missing description" in the blank rows for Description xlsx then Mapping Load
Answer: A
Explanation:
This strategy involves using the ApplyMap function with three parameters after the Mapping load. This will allow the data architect to add the department descriptions or a default value when the department does not have a description. Source: Qlik
NEW QUESTION # 23

Which values does the OrderDate field contain after executing the script?
- A. 20210131, 2020/01/31, 31/01/2019, 0
- B. 20210131, 2020/01/31, 31/01/2019, 9999

- D. 20210131,2020/01/31,31/01/2019
Answer: C
NEW QUESTION # 24
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. A security rule has been applied to the sheet object
- B. The affected users were NOT added to the Section table
- C. An Omit field has been applied
- D. Section access restricts too many records
Answer: D
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.
NEW QUESTION # 25

What should the data architect do to meet these requirements?
- A. Use the data manager
- B. Create a canonical calendar
- C. Load a calendar island
- D. Create five master calendars
Answer: B
