The following questions will help you measure your understanding of the material presented in this chapter. Read all the choices carefully as there may be more than one correct answer. Choose all correct answers for each question.

Customizing the Program Neighborhood Interface and Recognizing ICA Toolbar Icons

1.	What encryption levels are included in the ICA client? (Choose all that apply.) Basic 40-bit 56-bit 64-bit 128-bit
2.	Which of the following is not a supported platform for the ICA client? Microsoft Windows 3.1 Apple Macintosh Palm OS Microsoft DOS BEOS
3.	Your company has a MetaFrame XP farm with several remote sites that use dial-up connections. One user, Juan, has been complaining that his session seems slow to respond. What could you check or change in Program Neighborhood to ensure that Juan's connection is more efficient or appears to be faster? Make sure bitmap caching is turned on for Juan's under ICA Settings… in the Tools menu. Increase the color depth of the Application Set. Reduce the settings of or turn off audio remapping in the properties of the Application Set. Enable SpeedScreen Latency Reduction.
4.	Which of the following clients can use Program Neighborhood? ýChoose all that apply.) Unix clients Win32 clients Macintosh clients Java clients Win16 clients
5.	Greg is a remote MetaFrame user in San Francisco, CA. He dials up to the Internet and tries to connect to a server farm in Austin, TX. When he tries to connect, though, he gets an error message that states 'Cannot connect to the Citrix server: There is no Citrix Server configured on the specified address.' What could be wrong? In the properties for the server farm, the check box Use Alternate Address For Firewall Connection is not selected. The client name in the file wfname.ini is a duplicate. Greg's encryption settings are too low. Client audio remapping has been turned off.
6.	A user named Amy is complaining that when she launches Microsoft Word, which is a published application, she gets an annoying window around the program that distracts her from her job. Her connection in Program Neighborhood is a custom connection. How could you help Amy get rid of this window on her computer? Edit her appsrv.ini file and add the line SetOutsideWindow=0ff. Have Amy click the Refresh button on her Program Neighborhood toolbar. Edit the properties of the published application on the server to be a seamless window. Edit the properties of the published application on the client to be a seamless window.
7.	If your client audio is set to High, what is the maximum amount of bandwidth the remapped audio can use? 16 Kbps 32 Kbps 64 Kbps 1.3 Mbps 128 Mbps
8.	You just published Microsoft Access to the users in the Dallas farm. Bob calls and complains that he cannot see the Microsoft Access icon in his application set. What would you do to correct this problem? Delete the application set, and create a new connection to the Dallas farm in the Application Set Manager view. Have Bob reboot the machine. Tell Bob to press the Refresh button on the Program Neighborhood toolbar. Have Bob edit the server farm properties and reduce the session screen size.
9.	Your human resources department has just given you a new application to publish on your server farm. They have stressed that security is critical, because the application includes the personal records of every employee. How would you publish this application to the users in a secure manner? Add the human resources global group to the local anonymous group on your server, and then publish the application anonymously. Publish the application explicitly to the human resources global group. Publish the application explicitly to the Everyone group. Publish the application anonymously.
10.	Which of the following protocols is not valid when making a Program Neighborhood connection? TCP/IP TCP/IP+HTTP RDP IPX/SPX NetBIOS
11.	You have been given the task to publish Microsoft Office XP, five accounting applications and three marketing applications to all of your users. How would you publish the applications so that the users would not get confused when they connect to the application set? Create global groups for each application group and publish them explicitly to each group. Create global groups for each application and publish them anonymously to each group. Create Program Neighborhood folders in CMC for each set of applications and then publish all of the applications to your users.
12.	Where would you change the bitmap cache settings in Program Neighborhood? Tools menu, ICA Settings, Bitmap Cache tab Properties on the application set Tools menu, Client Settings, Bitmap Cache tab Tools menu, General tab
13.	One of your users, Andy, calls to say that he is having problems in his terminal emulation application on Citrix. Andy says that when he presses SHIFT-F2 to print in the application, his title bar goes away. When he tries it again, his title bar returns. What is Andy's problem? Andy suffers from working too much and is making the wrong keystrokes. Andy should just use the File | Print menu options. Andy should configure the hotkey for Toggle Title Bar under the Tools | ICA Settings | Hotkeys tab to be something other than SHIFT-F2.
14.	Mike is a user on your local LAN. He complains that when he listens to Internet radio stations on the MetaFrame server, the sound quality is very poor, making it difficult to dance to when he is on breaks. How can we fix this? Turn off client audio remapping. Decrease his client audio settings to Low. Increase his client audio settings to Medium. Increase his client audio settings to High.
15.	You just imaged three new PCs and sent them out to your users. Your users call you and complain that when they try to connect to the Citrix farm, only one user at a time can log on, while the other two get error messages. How can you correct this problem? ýChoose all that apply.) Rename the computer names under Network in the Control Panel. Edit the wfcname.ini on the machines and change the CLIENTNAME to be unique on each machine. Choose Tools menu | ICA Settings | General tab, and then make the Client Name entry unique on each machine. Make sure the login names for each user are unique.
16.	The installation path for the ICA PassThrough client on a MetaFrame server is %systemroot%\system32\ICA PassThrough %homedrive%\system 32\ICA PassThrough %systemroot%\ICA PassThrough %systemdrive%\system\ICA PassThrough
17.	The term TAPI refers to what? The WinSock protocol The Telephone Application Programming Interface found under the Modems item in the Tools menu The Telephone Action Programming Interface found in the Properties dialog box of a custom connection The feeling you get after too much coffee
18.	A user named Bruce in the Graphics department just bought a new iMac and set it up on the LAN. He downloads and installs the latest Macintosh PN client for the machine. However, he now is complaining that he can't see his application set. What is the problem? Bruce is not using the Application Set Manager view. Bruce does not have his firewall settings configured correctly. Bruce is not using a compatible protocol. Bruce is not using a client that supports application sets.
19.	Which ICA clients have built-in TAPI emulation support? ýChoose all that apply.) DOS Win16 Win32
20.	Which color depths does Program Neighborhood support? ýChoose all that apply.) 640×480 800×600 1024×768 1280×1024 1600×1200

Answers

1.	þ A, B, C, and D are all valid encryption levels. ý D is incorrect because 64-bit is not an available encryption level.
2.	þ A, B, and D all have valid Citrix ICA clients. ý C and E are incorrect because there is no Citrix ICA client written for these platforms.
3.	þ B is the correct answer because increasing the color depth of the Application Set would cause more information to be sent over the connection. You should reduce the color depth to help speed up a slow connection. ý A is incorrect because bitmap caching helps speed up a connection by caching commonly used bitmaps to the local hard drive. C is incorrect because turning audio remapping off will speed up a connection by eliminating the need to send audio information. D is incorrect because SpeedScreen Latency Reduction gives the user instant feedback for mouse strokes and keyboard entry, thus making the session appear to run faster.
4.	þ A, B, C, D, and E can all use Program Neighborhood. Win32 and Java clients use Program Neighborhood natively, and all other clients can use Program Neighborhood through an ICA PassThrough connection.
5.	þ A is correct because Greg is unable to connect to the public address of the ICA browser. When this option is checked, the client will use the alternate address configured on the server. This option is set using the altaddr.exe command. ý B is incorrect because although this would cause an error message, the client would still be able to contact the Citrix server. C is incorrect because encryption settings that are too low would not keep the client from connecting, but could restrict the user from using a session if the minimum encryption required for that application set was not met. D is incorrect because turning off client device mapping would not stop a user from connecting to a Citrix server.
6.	þ D is correct because we need to edit the properties of the custom connection to change it to a seamless window. When a custom connection is configured, we have the option of using a remote window or a seamless window. When a seamless window is used, the application appears to be running on the local machine and does not have a windowed box around the application. ý A is incorrect because there is no value SetOutsideWindow in appsrv.ini. B is incorrect because refreshing the Program Neighborhood window will not change the settings of the connections. C is incorrect because client settings would override the server settings. Also, the question asked what you could change on the local machine.
7.	þ D is correct. Audio remapping set to High can use up to 1.3 Mbps of bandwidth. ý A, B, C, and E are incorrect because the High setting could use more or less than these answers.
8.	þ C is correct because this would cause the ICA client to request an update to the Dallas farm from the ICA browser, showing the new published application in the farm when the request was completed. ý A is incorrect because this may refresh the application set icons, but it is not the most efficient method of getting a new list of applications. B is incorrect because, although this would probably refresh the application set the next time the user logs in to Program Neighborhood, it is not the best answer. D is also incorrect because session screen size has no impact on application set connections.
9.	þ B is correct. When security is important, you should always publish to Explicit users. Explicitly published applications require domain authentication before a user connects to a session. Anonymously published applications do not require a logon to connect. ý A is incorrect because this would not tighten security or require domain authentication. C is incorrect because this would allow anyone in the domain access to the application. D is incorrect because it would not require a logon.
10.	þ C is not a valid protocol. RDP is used with the Microsoft Windows Terminal Services client software. ý A, B, D, and E are all valid PN protocols.
11.	þ C is correct because using PN folders is the easiest way to manage a large number of applications. For example, you could create an Office folder, an Accounting folder, and a Marketing folder. ý A and B are incorrect because publishing the applications to different groups would not separate the applications logically in PN.
12.	þ A is the correct location to set the bitmap cache settings. ý B, C, and D are all invalid locations.
13.	þ C is correct. Under this tab, we can change the hotkeys if they conflict with an application. The disappearing title bar Andy experienced was due to this hotkey being set to Toggle Title Bar on the application by default. ý A and B are incorrect because this would not fix Andy's problems with keystrokes.
14.	þ D would be the correct setting for LAN usage, which is up to 1.3 Mbps of bandwidth for high quality audio. This setting should be used with caution, as several users with this setting could bog down the network, and should not be used for low speed connections. ý A, B, and C are incorrect because these would not improve the audio quality on Mike's session.
15.	þ B and C are correct. The client names for each client must be unique when connecting to a Citrix server. This can be changed in either of these two places with the same result. If two or more PN client names are the same, an error will occur when more than one user tries to log in. ý A and D are wrong because this will have no effect on the PN client name.
16.	þ A is the correct path for the ICA PassThrough Client. ý B, C, and D are all invalid installation paths.
17.	þ B is the correct answer. The TAPI interface lets you configure modems and telephony settings for dial-up connections. ý A, C, and D are invalid answers because they do not correctly describe the term.
18.	þ D is correct because only Win32 and Java clients can use the Application Set Manager view. Alternatively, you could publish PN on the server using ICA PassThrough and have Bruce set up a custom connection to this published app; or you could install and run the Java client on the iMac. ý A, B, and C are all incorrect because these solutions will not allow Bruce to connect to an application set.
19.	þ A and B are correct. Since these clients do not support TAPI natively on the OS, TAPI must be emulated by the ICA client. ý C is incorrect because Win32 clients support TAPI natively so no emulation is required.
20.	þ A, B, C, D, and E are all supported color depths in Program Neighborhood.
