You have a CSV file that contains user complaints. The file contains a column named Logged. Logged contains the date and time each complaint occurred. The data in Logged is in the following format: 2018-12-31 at 08:59.
You need to be able to analyze the complaints by the logged date and use a built-in date hierarchy.
What should you do?

A. Change the data type of the Logged column to Date.
B. Apply a transformation to extract the last 11 characters of the Logged column and set the data type of the new column to Date.
C. Create a column by example that starts with 2018-12-31 and set the data type of the new column to Date.

Selected Answer: C

Splitting columns by delimiter " at " is the best option though. Column by examples would do the same.

if C is true, then this data column is created by ourselves, not actually contain the info from Logged data of the csv file? How would it connect to the Logged data?

Because this feature creates dynamic formula based on your example.

Pour créer une hiérarchie de date, il faut créer une nouvelle colonne . C est juste.

I think that the reason for the answer to be C and not A is because of the format "2018-12-31 at 08:59" the "at" word makes the data type string which is not going to be able to parse as Date type.
