Salesforce Certified Advanced Administrator — Question 114

How should an administrator ensure the appropriate number of digits are entered into the custom encrypted field created to capture credit card numbers on the Opportunity object?

Answer options

• A. Create a validation rule to ensure the length.
• B. Use the credit card number mask type.
• C. Define the number of mask characters.
• D. Enter the number of digits at the field level.

Correct answer: A

Explanation

The correct answer is A because a validation rule is specifically designed to enforce data integrity by checking the length of the input, which is essential for credit card numbers. Options B and C do not directly address the requirement for a specific digit length, while option D does not provide a method for validation and enforcement of the digit count.
