A company has 50 clients backing up to an Dell Avamar server. The storage administrator has decided to enable desktop/laptop (DTLT) support for several of the Microsoft Windows client machines. Where is this support enabled?

Desktop/Laptop (DTLT) support is a client-side characteristic that must be configured when the Avamar client software is installed and registered with the Avamar server. During the interactive installation wizard, the administrator is prompted to specify whether the machine is a desktop or laptop. This setting optimizes the client's behavior for typical end-user environments, such as using lower-priority network and CPU resources and enabling the user-facing restore interface.

B. Avamar Windows Client Options menu: This menu is for post-installation configuration of backup options, not for setting the fundamental client type like DTLT.
C. Avamar Administrator Policy window: Policies define backup schedules, datasets, and retention. They are applied to clients but do not define the client's DTLT status.
D. Windows File System plug-in: The plug-in handles the file system backup process; its settings do not control the DTLT designation of the client itself.

- Dell Avamar 19.9 Administration Guide, Page 379, "Desktop/Laptop backup overview". This section describes DTLT as a client configuration, implying it is set at the client level during setup.
