Exam Prep Questions

1.

You are implementing solutions for IT initiatives to cut costs and improve performance through server consolidation. You also want to increase the number of users who are supported on each server and are determining whether to enable CPU utilization management. Under what circumstances would it not be advisable to enable CPU utilization management for all users?

	When user demand exceeds available CPU resources and causes farm performance to degrade
	When the server allocates an equal share of the CPU to each user
	On farms or servers that host CPU- intensive applications that may require a user to have a share of the CPU greater than that allocated to fellow users
	For individual servers within the farm

A1:

Answer C is correct. CPU utilization management allocates an equal share of the CPU to each user. If you have special users who require a greater share of the CPU, either you must not enable CPU optimization on these farms or servers, or you must explicitly allocate these users a greater share of CPU resources. Depending on the needs of the application, this may produce undesirable performance restrictions on these users.

Answers A, B, and D are all incorrect. Answers A and B are both good reasons to enable CPU utilization, and D is not a reason not to enable this option.

2.

An application fails to run properly after you upgrade a server to Presentation Server 4.0. The Virtual Memory Optimization feature is enabled. You notice the following behavior: The application was working properly in Presentation Server 3.0. The application works properly when the IMA Service is stopped . The application fails at the server console when the IMA Service is running. What should you do to get the application to run?

	Nothing. The application is incompatible with Presentation Server 4.0.
	Disable the Virtual Memory Optimization feature.
	Stop the IMA service.
	Add the application to the exclusion list.

A2:

Answer D is correct. If an application is not functioning correctly after being optimized by the Virtual Memory Optimization feature, it can be placed on the application exclusion list. The exclusion list is located in the Presentation Server Console under the farm properties in the Memory Optimization section.

Answers A, B, and C are incorrect. The application is simply not compatible with the new memory optimization feature of MPS 4.0. Although disabling Virtual Memory Optimization will correct the problem, it will eliminate any benefits that could be gained from the optimization performed with other applications. Stopping the IMA service is not an option because it will impair the behavior of the Presentation Server in the farm.

3.

When the Citrix Virtual Memory Optimization service is started, it is responsible for monitoring applications as they load and recording any DLL access collisions that occur. These collisions are recorded to what file? (Choose one.)

	Collisions.SFO
	Repair.SFO
	Bind####.SFO
	VMem.SFO
	Exclude.SFO

A3:

Answer B is correct. Collisions are recorded in the Repair.SFO file, which is then read at scheduled intervals and during bootup in order to optimize the conflicting programs.

Answers A, D, and E are incorrect because they represent files that are not part of the Virtual Memory Optimization feature. Answer C is incorrect because the Bind####.SFO file contains the list of optimized DLLs and their associated memory savings.

4.

Where is the list of processes and components excluded from memory optimization managed? (Choose all that apply.)

	In the server farm node
	In the server node
	In the published application node
	In the Registry

A4:

Answers A and D are correct. The list of processes and components to exclude from memory optimization is managed only within the server farm node and within the Registry. Citrix recommends that all changes be made in the farm node and not directly in the Registry.

Answers B and C are incorrect. You can enable or disable memory optimization in the server node, but you cannot modify the individual applications that are excluded. The published application node contains no memory optimization settings.

5.

You are customizing options for the Web Interface for a Presentation Server installation in a medical clinic. Users frequently need to move between a variety of client devices and quickly disconnect and reconnect running applications. You have just upgraded from a legacy MetaFrame 1.8 environment to a completely new MPS 4.0 environment and have set up Workspace Control. However, it is not working. What should you do?

	Turn off interoperability mode.
	Upgrade all ICA clients to version 8 or higher.
	Implement SmoothRoaming with Smart Cards.
	Configure connection settings in the Presentation Server Console.

A5:

Answer B is correct. Workspace Control cannot be used with the ICA Client for Windows CE, the Win32 client prior to version 8, and Remote Desktop Connection software. Additionally, this feature works only with servers running MetaFrame Presentation Server version 3.0 or later.

Answer A is incorrect because interoperability mode does not even exist in MPS 4.0. Answers C and D are also incorrect because SmoothRoaming with Smart Cards is not a requirement for Workspace Control.

6.

Many of the users in your organization have PDAs. You want to use the new PDA synchronization support feature in MetaFrame Presentation Server. Which of the following statements about PDA synchronization support are true? (Choose all that apply.)

	ActiveSync must be used as the synchronization agent.
	It does not work for pass-through ICA connections and reconnection to disconnected sessions.
	It is supported in all editions of Presentation Server 4.0.
	It offers full Plug and Play (PnP) support for USB-tethered Windows CEbased PDAs.
	All of the features of ActiveSync are supported.

A6:

Answers A, D, and E and are correct. PDA synchronization requires that ActiveSync be used as the synchronization agent, and all of the features of ActiveSync are supported. It offers full Plug and Play (PnP) support for USB-tethered Windows CEbased PDAs.

Answer B is incorrect. The restrictions on pass-through ICA connection support and reconnecting to disconnected sessions are limitations of local IP address redirection, not PDA synchronization. Answer C is incorrect because PDA synchronization is available only in the Advanced and Enterprise Editions of MetaFrame Presentation Server.

7.

Which of the following statements concerning new features and changes in MetaFrame Presentation Server 4.0 is NOT true?

	UNIX and Windows licenses can now be shared in the Enterprise Edition.
	MetaFrame 1.8 interoperability mode is now supported.
	MPS 4.0 now includes UNIX Presentation Server.
	Conferencing Manager is now included as a component of Presentation Server.

A7:

Answer B is correct. MetaFrame 1.8 interoperability mode is no longer supported in 4.0.

Answers A, C, and D are all true statements about MPS 4.0.

8.

Certain users in your organization have locally attached scanners . You want these devices to be transparently redirected so that they can be controlled and accessed from applications running on the Presentation Server. What should you do?

	Enable Windows key pass-through.
	Enable Workspace Control.
	Enable TWAIN redirection.
	Enable application isolation.

A8:

Answer C is correct. TWAIN redirection enables you to transparently redirect locally attached imaging devices, such as scanners, from the client to the server. Users can thus control client-attached imaging devices from applications that run on the server. The application can detect and use the imaging device from within the session, just like a client-based application.

Answers A, B, and D are incorrect. None of these features are associated with the redirection of local client devices such as scanners.

9.

You want to run an application on your Presentation Server that requires a unique IP address for each user. You have assigned a total of 10 IP addresses because you have only 10 users who run this application. Occasionally, you get phone calls from these users saying they are receiving a message stating that an IP address is not available. When this happens, the users cannot run their application. What is the most likely cause of this issue? (Choose one.)

	A user is disconnecting and reconnecting from a different workstation, consuming additional licenses.
	The application is crashing and not freeing up a virtual IP address.
	The application does not support the use of virtual IP addresses.
	More than 10 users are connecting to the server.
	A and B.

A9:

Answer D is correct. Each user who connects to a server with virtual IP addressing enabled will receive a virtual IP address from the pool, regardless of whether that user actually uses an application that requires that address. If all available IP addresses are exhausted, users will receive a message stating that no more addresses are available for use.

Answers A, B, C, and E are all incorrect. Virtual IP address assignment is not affected by disconnecting and reconnecting (you keep the same IP). Because the IP is associated with the session, the application crashing has no effect on this. Even if an application does not support the use of virtual IP addresses, it does not cause this error to occur.

10.

Many of the users in your organization have PDAs. You want to use the new PDA synchronization support feature in MetaFrame Presentation Server. How do you enable PDA synchronization?

	Enable the rule Client Devices/Resources/PDA Devices/Turn on automatic virtual COM port mapping.
	Disable the rule Client Devices/Resources/PDA Devices/Turn on automatic virtual COM port mapping.
	Enable the rule Client Devices/Resources/Ports/Turn off COM ports (or set it to Not Configured).
	Disable the rule Client Devices/Resources/Ports/Turn off COM ports (or set it to Not Configured).
	B and C
	A and D

A10:

Answer F is correct. To enable PDA synchronization, you need to configure a policy. The PDA Devices policy rule is disabled by default.

Answer A alone is incorrect because PDA devices do not connect if the COM port redirection has been turned off.

Answer B is incorrect because you want to enable this rule, not disable it.

Answers C and D are incorrect on their own because enabling or disabling the COM port option does not enable PDA redirection unless the PDA Devices rule is also enabled properly.

Answer E is incorrect because it does not set the proper policies correctly.
