A system database administrator can manage and restrict functionalities within tenant databases using tools available in the SAP HANA Cockpit. The "Manage Restricted Features" app provides a user-friendly interface to explicitly disable specific, predefined features for a selected tenant. Alternatively, the "Manage Database Configuration" app allows for more granular control by enabling the administrator to modify configuration parameters (.ini files) for a tenant, which can effectively disable services or functionalities governed by those parameters. Both methods are performed by an administrator connected to the system database.

B. Using the resident hdblcm tool: The SAP HANA Database Lifecycle Manager (hdblcm) is used for installation, updates, and system-level configuration changes, not for managing functional features within a tenant database.

C. Using the hdbuserstore tool: This is a client-side utility for securely storing database connection credentials. It has no administrative capability to enable or disable database functionalities.
