You design a screen for the survey form. The first question asks a customer to select the age category from a dropdown, the second — select three interests from the list of 25 items. And the last one asks a customer to put a home zip code, and the form populates the customer’s county and state. 
Please select column types for the answers (Question 1, Question 2, Question 3) that you would model in the design.

Answer options:

A.Choices, Multiline text, Lookup
B.Lookup, Choices, Choice
C.Choice, Lookup, Whole number
D.Choice, Choices, Lookup
E.Choice, Multiline text, Lookup
F.Text, Choices, Whole number

Correct Answers: D 
The Dataverse has a list of column data types. As a Solution Architect, you need to understand the differences between the types and select the appropriate one to store application data. Because if you created a column, you could not change its data type. 
The answer to the first question provides a list of the age categories that should not contain more than ten items. Such a list is a perfect example of the Choice data type because it is a static list, stores only label and value, can be used for a long time (does not require values to retire), and, from the user interface point of view, contains less than 200 items. You need to have an admin/customizer type access if you need to modify the Choice table. 
The answer for the second question is also the type of choice, but with multiple selections. The Dataverse provides the Choices data type for the columns required to select several items from a limited list. 
And the answer to the last question is the Lookup data type. The Lookup column (or reference data) references another table that stores data other than a label and pair, like a custom table for US zip codes. Such a table can contain all the zip codes (or postal codes), counties, cities, states information. If you search the table by provided zip code, the Dataverse returns the record with the name of the county and state that can be populated on the screen. Modifications to the values in a lookup table do not require admin level — any user with read-write permissions for the table can add/modify records. 
All other options are incorrect.
