Scenario: After gathering basic requirements from Nether Tech Inc. administrators and IT
personnel, an engineer must decide whether a virtual or physical implementation is best suited for
the environment. Several key requirements are listed below. Peak time is gam; approximately
4,000-4,500 logon attempts will be made then. Most users will have the same core applications
such as Microsoft Office and Adobe Reader. Some custom applications need to be updated
quarterly. Remote users and traveling field agents will need secure remote access to the
environment. Several applications in the environment CANNOT co-exist together. Some
applications will NOT run on an application server. Based on these requirements, which kind of
implementation should the engineer recommend?

A. A virtualized implementation that leveragesXenDesktop Platinum
B. A physical server farm that leverages XenApp on physical servers
C. A physical server farm that leverages XenApp and Provisioning Services

virtualization platform. Provisioning Services will be used to rapidly provision desktop and server
images. XenOesktop will be used to publish and manage client desktops. Nether Tech Inc.'s
existing environment consists of a DHCP server, a DNS server, a domain controller, several
managed switches with spanning tree protocol and several routers. Which modification should the
Citrix Engineer recommend from a networking standpoint in order for all of the new Citrix products
to be highly optimized?

A. Enable task offload on the virtual machine.

Scenario: The new design document for Nether Tech Inc. requires that the Citrix Engineer perform
the following:
1. Upgrade from Presentation Server 4.0 to XenApp 5.0 for Windows Server 2008.
2. Integrate the XenApp 5.0 environment with the existing XenDesktop solution, which includes
Provisioning Services.
The engineer has successfully completed the upgrade to XenApp 5.0 for Windows Server 2008
and must now implement the second stage of the design by integrating the XenApp 5.0 farm into
the XenDesktop environment so that published applications can be accessed from within the
XenDesktop virtual desktops. The engineer has just created a XenApp Services Web Interface site
that enumerates applications from the XenApp 5.0 farm.
Which additional steps must the engineer take to integrate the existing XenApp 5.0 farm into the
XenDesktop environment?

Scenario: The engineer at Nether Tech Inc. is in the process of implementing a new manufacturing
application called Bottled Pro. The new application has certain requirements that prevent delivery
in the existing XenApp environment. XenDesktop was implemented in order to provide the
application to the users of the Manufacturing department. The new application will be installed as
part of the vDisk that will be provisioned to the Manufacturing department users. In addition to the
new application, users from the Manufacturing department must have access to a set of
applications that will be delivered as streamed applications from the existing XenApp farm. The
engineer's task is to create the Windows XP vDisk that will be provided by Provisioning Services
to serve all 50 virtual desktops. The engineer needs to decide which Citrix software needs to be
installed on the master target device before building the vDisk so users can access their required
applications. Users will only be permitted to access XenApp environments from the Manufacturing

follow Citrix best practice for installing only the required software to satisfy the application delivery
requirements. Which four software programs are appropriate for installation? (Choose four.)

the production Provisioning Services server. The engineer has already made a copy of the vDisk,
placed it in a test environment and removed the desired software from the new vDisk. Which five
steps should the engineer take when provisioning the new vDisk to a select number of XenApp
servers according to best practice? (Choose five.)

A. Enable automatic updates for the new vDisk.
B. Enable incremental updates for the new vDisk.
C. Boot the target devices from the newly updated vDisk.
D. Assign the original and newvDisks to all target devices.
E. Create a delta file that will be used to update the vDisk.
F. Change the filename of the new vDisk and increment the build number.
G. Select the access mode for the new vDisk to be the same as that of the original vDisk.
H. Select the cache type for the new vDisk to be the same as that selected for the original vDisk.
