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

Answer: D

Explanation:

A validation rule is a formula that validates the data entered by a user and prevents the record from being saved if the data does not meet certain criteria. In this case, the administrator can create a validation rule to ensure that the custom encrypted field for credit card numbers has exactly 16 digits. The other options are not applicable for encrypted fields.
