Your company has an Active Directory Domain Services (AD DS) domain. All servers run Windows
Server 2008 R2. You provide access to some applications through a virtual desktop infrastructure
(VDI) environment. All virtual desktop computers are located in an organizational unit (OU) named
VirtualDesktops. All other client computer objects are located in an OU named Desktops. Many users
experience long logon times when logging into virtual desktop computers due to large roaming
profiles. You need to reduce the user logon times for virtual desktop computers. What should you
do?
A.
On each virtual desktop computer, set a disk quota on the system drive.
B.
Create a Group Policy object (GPO) that enables folder redirection for all users. Enable loopback
processing, and link the GPO to the VirtualDesktops OU.
C.
Create a Group Policy object (GPO) that enables folder redirection for all users. Enable slow link
detection, and link the GPO to the VirtualDesktops OU.
D.
On each client computer, set the temporary folders option to not use session-specific temporary
folders.
Explanation:
Combine Roaming User Profiles with Folder Redirection When a user gets a roaming user profile, the
data and settings that are stored in the user’s local profile directories become mobile. The profile
data is stored on a server and copied to a workstation when the user logs on. Storing this data on
servers simplifies data backup and security. However, because large folders, such as My Documents,
are copied, there can be logon delays. You can avoid these delays by using Folder Redirection in
combination with Roaming User Profiles. When a user profile folder is redirected to a shared folder
on the network, the folder is no longer part of the user profile. While other profile data is copied to
the local workstation when the user logs on, the redirected folder remains on the server and is
accessed over the network. Limiting use of Group Policy loopback processing if you use roaming
profiles The User Group Policyloopback processing mode policy setting is an advanced option that is
intended to keep the desktop configuration the same regardless of who logs on. This option is
appropriate for use in certain closely managed environments, such as classrooms, public kiosks,
reception areas, servers, and terminal servers. When you enable the loopback processing policy
setting in a GPO, you can configure user-based policy settings within that GPO, and those settings
are applied regardless of which user logs on to the computer, meaning that those settings override
individual user settings. When you use the User Group Policyloopback processing mode policy
setting, you must ensure that both the computer and user portions of the GPO are enabled. The
User Group Policyloopback processing mode policy setting is available in the Computer
Configuration\Administrative Templates\System\Group Policy node of the Group Policy Object
Editor. By default, the user’s Group Policy objects determine which user settings apply. When you
enable this policy setting, you also specify either the Replace mode or the Merge mode, which
determines the policies that are applied. Replace mode The user settings that are defined in the
computer’s Group Policy objects replace the user settings that are typically applied to the user.
Merge mode The user settings that are defined in the computer’s Group Policy objects and the user
settings that are typically applied to the user are combined. If the settings conflict, the user settings
in the computer’s Group Policy objects take precedence over the user’s policy settings. If you disable
or do not configure the User Group Policyloopback processing mode setting, the user’s Group Policy
objects determine which user settings apply. http://technet.microsoft.com/enus/library/cc736881(v=ws.10)
