What must be done to activate Multi-Tenancy features in Deep Security Manager?

To activate Multi-Tenancy features in Deep Security Manager, it is necessary to activate the Multi-Tenancy license. This is because the license enables the functionalities required for managing multiple tenants within the system. Without this specific license, the features necessary to segregate and manage different tenants’ environments and data will not be accessible, even if the system has the technical capability to support it.

The other choices do not pertain directly to activating Multi-Tenancy. Setting up a single-tenant model might establish a simpler configuration, but it does not facilitate Multi-Tenancy features. Performing a full system upgrade could enhance system capabilities, but it is not a requirement for activating the Multi-Tenancy functionality itself. Connecting to all tenant databases might be relevant for operational purposes within a Multi-Tenancy setup, but it does not impact the activation of the features. Thus, activating the appropriate license is the crucial step to enable Multi-Tenancy in Deep Security Manager.
