  2. Intersect
  3. AddressLookup
  4. Simplify

Answer(s): A

Binning is a GeoAnalytics operation that allows data points to be grouped into hexagonal areas based on a geographic field, such as postal codes. The data architect can use binning to group the location points by postal code and then color code the resulting hexagonal areas based on the number of vendors in each location.
This operation is useful for visualizing spatial data and identifying patterns or trends in the data.



Refer to the exhibit.



A data architect is working with an app and creates some visualizations to check the dat

  1. Some visualizations show issues in the data set.
    * The Sales by Country table shows a total OrderValue of 18,300 sales while the KPI shows a total OrderValue of 20,600.
    * The Sales monthly trend bar chart does not work with the Month field.
    Which two data issues should the data architect fix in the app? (Select two.)

  2. The Month field does not exist in the Orders table and needs to be incorporated in the table using he Calendar table.
  3. In the Orders table, some CustomerlD values are null because there are orders with no customer.
    and needs to be incorporated in the table using the Calendar table, null because there are orders with no customer
  4. In the Orders table, some values in the CustomerlD field do not exist in the Customers table.
  5. The OrderDate field values in the Calendar table do not match with the values in the OrderDate field from the Orders table

Answer(s): C,D



Refer to the exhibit.



A data architect is working on a Qlik Sense app the business has created to analyze the company orders and shipments. To understand the table structure, the business has given the following summary:
· Every order creates a unique orderlD and an order date in the Orders table · An order can contain one or more order lines one for each product ID in the order details table · Products in the order are shipped (shipment date) as soon as tliey are ready and can be shipped separately
· The dates need to be analyzed separately by Year Month, and Quarter The data architect realizes the data model has issues that must be fixed.
Which steps should the data architect perform?


  1. 1. Create a key with OrderlD and ProductID in the OrderDetails table and in the Orders table
    2. Delete the ShipmentID in the Shipments table
    3. Delete the ProductID and OrderlD in the OrderDetails table
    4. Concatenate Orders and OrderDetails
    5. Create a link table using the MasterCalendar table and create a concatenated field between OrderDate and ShipmentDate

  2. 1. Create a key with OrderlD and ProductID in the OrderDeta Is table and in the Shipments table
    2. Delete the ShipmentID in the Orders table
    3. Delete the ProductID and OrderlD in the Shipmi
    4. Left join Orders and OrderDetails
    5. Use Derive statement with the MasterCalendar table and apply the derive fields to OrderDate and ShipmentDate

  3. 1. Create a key with OrderlD and ProductID in the OrderDetails tab e and in the Orders table
    2. Delete the ShipmentID in the Shipments table
    3. Delete the ProductID and OrderlD in the OrderDetails
    4. Left join Orders and OrderDetails
    5. Use Derive statement with the MasterCalendar table and apply the derive fields to OrderDate and ShipmentDate

  4. 1. Create a key with OrderlD and ProductID in the OrderDetails table and in the Shipments table
    2. Delete the ShipmentID in the Orders table
    3 Delete the ProductID and OrderlD in the Shipments table
    4. Concatenate Orders and OrderDetails

Answer(s): D

Explanation:



Multiple department fields in a dataset require a description A data architect needs to add the department descriptions or a default value when the department does NOT have a description
Which strategy should the data architect use to meet these requirements?

  1. ApplyMap with two parameters after the Mapping load
  2. Left Join between tables and Description xlsx in every Department table
  3. Enter "Missing description" in the blank rows for Description xlsx then Mapping Load
  4. ApplyMap with three parameters after the Mapping load

Answer(s): D

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
