Qlik Sense System Administrator Certification (2018) — Question 1

A data architect adds a field to an existing data model that contains new values for the ProductGroup. The business analyst needs to efficiently update the app and meet these requirements:
✑ Use the existing charts, which are built using a master item dimension called ProductGroup
✑ Existing charts must use the new values for ProductGroup
✑ Business users must be able to compare the new and old values
How should the business analyst meet these requirements?

Answer options

• A. Change the ProductGroup dimension using the new field, and create a new dimension in the master items for the old field.
• B. Create a calculated dimension on the charts to allow the users to compare the new value to the old value.
• C. Replace the dimensions on all charts to use the new ProductGroup field added to the data model.
• D. Use set analysis on the chart measures to see the difference in ProductGroup between the new field and the old field.

Correct answer: A

Explanation

Option A is correct because it allows the existing charts to remain functional while providing access to both new and old values through separate dimensions. Option B, while useful for comparison, does not meet the requirement of using the existing charts with the new values. Option C replaces the dimensions entirely, which would disrupt the existing charts. Option D focuses on measures rather than dimensions, making it less suitable for the requirement to use existing charts.
