Universal Charities (UC) uses Salesforce to collect electronic donations in the form of credit card deductions from individuals and corporations.
When a customer service agent enters the credit card information, it must be sent to 8 3rd-party payment processor for the donation to be processed, UC uses one payment processor for individuals and a different one for corporations.
What should a developer use to store the payment processor settings for the different payment processors, so that their system administrator can modify the settings once they are deployed, if needed?
答案：D
解題說明：
Hierarchy custom setting is a way of storing the payment processor settings for the different payment processors, so that the system administrator can modify the settings once they are deployed, if needed. Hierarchy custom setting is a type of custom setting that can store configuration data that can vary for different users or profiles. Hierarchy custom setting can be accessed from Apex code, and can be used to control the behavior of the code based on the user's context. By using hierarchy custom setting, the developer can create a custom setting that can store the payment processor URL and credentials for the individual and corporate customers. The developer can then use the custom setting in the Apex code to determine which payment processor to use based on the user's profile or identity. The system administrator can also change the custom setting values in the user interface, without modifying the code, if the payment processor settings change. Reference: [Hierarchy Custom Settings], [Access Custom Settings]
