Which of the following information MUST be provided for user account provisioning?

A full name is commonly collected during provisioning but is not strictly required, as multiple users can share the same name, making it insufficient as a mandatory provisioning element.

A unique identifier (e.g., username, user ID, or employee number) is the fundamental requirement for account provisioning because it ensures each account can be distinctly identified within the identity management system. Without a unique identifier, the system cannot differentiate between users, enforce access controls, or maintain accurate audit trails. This is a core principle of identity and access management (IAM) across all platforms and standards.

Security questions are an optional secondary authentication mechanism and are not a mandatory component of the initial account provisioning process.

Date of birth is personally identifiable information that may be collected for verification purposes but is not a required element for creating and provisioning a user account.
