The customer requires secure access control for sensitive customer data .

Which functionality is most important?

A. Field-Level Security

B. Two-Factor Authentication (2FA)

C. Encrypted Case Histories

Answer: A

Explanation:

Field-Level Security (FLS) is crucial in controlling access to sensitive data fields within Salesforce. By limiting visibility and editability of specific fields based on user roles, FLS ensures that sensitive information is only accessible to authorized users. While Two-Factor Authentication and encrypted data are also important, FLS is most directly related to controlling access at the data field level, making "A. Field-Level Security" the most important functionality for secure access control.
