IBM SPSS Statistics Level 1 v2 — Question 32

In the Masking Policy Editor in the Data Masking stage of your job, you have specified for a column containing credit card numbers the Random Replacement masking policy. For the Copy option you have specified "(1,2)(3,4)".
What changes will be made to a credit card number, such as 6327664369, to mask it?

Answer options

• A. Digits 1 through 2 and digits 3 through 4 will be randomly changed. The rest of the digits will remain the same.
• B. Digits 1 through 2 and digits 3 through 4 will remain the same. The rest of the digits will be randomly changed.
• C. The 2 digits starting at digit 1 and the 4 digits starting at digit 3 will remain the same. The rest of the digits will be randomly changed.
• D. The 2 digits starting at digit 1 and the 4 digits starting at digit 3 will be randomly changed. The rest of the digits will remain the same.

Correct answer: D

Explanation

The correct answer is D because the Random Replacement masking policy will change the specified digits while leaving the others intact. Options A, B, and C incorrectly describe the behavior of the masking policy regarding which digits remain unchanged and which are altered.
