Exam DP-200 topic 3 question 5 discussion

HOTSPOT -
You have an Azure SQL database that contains a table named Customer. Customer contains the columns shown in the following table.

You plan to implement a dynamic data mask for the Customer_Phone column. The mask must meet the following requirements:
✑ The first six numerals of the customer phone numbers must be masked.
✑ The last four digits of the customer phone numbers must be visible.
✑ Hyphens must be preserved and displayed.
How should you configure the dynamic data mask? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Suggested Answer:
Exposed Prefix: 0 -
The first six digits must be masked. There is thus no exposed prefix.

Padding String: XXX-XXX -
The first six digits must be masked and hyphens must be preserved.

Exposed Suffix: 5 -
The last 4 digits must be visible. There is not option for 4 but we can use 5 as it would include the hyphen before the last 4 digits.
