The Provisioning Request Configuration plug-in is the specific administrative tool, typically used within iManager, designed for the lifecycle management of Provisioning Request Definitions (PRDs). This plug-in provides the interface for administrators to create, modify, delete, activate, inactivate, and retire the definitions that govern how users request and are granted access to resources. These actions directly control which request forms are available to users and how the associated fulfillment workflows are initiated.

A. User Application Driver: This is a back-end component that facilitates communication between the Identity Vault and the User Application; it is not a user-facing administrative tool for managing definitions.

B. User Application Portlets: These are the front-end UI components for end-users to submit requests or perform approvals, not for administrators to manage the underlying request definitions.

C. Workflow Administration plug-in: This tool is used to manage active or completed workflow instances (e.g., reassigning tasks, viewing process status), not for managing the PRD templates that initiate them.

Section 6.2, "Managing Provisioning Request Definitions with the Provisioning Request Configuration Plug-in": This section explicitly states, "You use the Provisioning Request Configuration plug-in for iManager to manage provisioning request definitions." It then details the specific actions available, including "Activate a provisioning request definition," "Inactivate a provisioning request definition," "Retire a provisioning request definition," and "Delete a provisioning request definition." This directly supports the correct answer.

Section 7.0, "Managing Workflows": This chapter describes the Workflow Administration plug-in, clarifying its role in managing workflow processes (instances) rather than definitions, which supports why option C is incorrect.
