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.

Identifying the Components of the ICA Packet

1.	What is the data protocol that exports the screen image? ICA Thinwire TCP FTP
2.	While analyzing a sniffer trace of ICA traffic, you begin examining the contents of the ICA packets. On an IPX network, using SecureICA and a dial-up connection, what packet components would you expect to find? ýChoose all that apply.) Command Encryption Compression Reliable
3.	Which ICA clients support full-screen test mode? Windows 32 Windows 16 Java DOS
4.	You need to provide UDP broadcast compatibility to your farm as you migrate from MetaFrame 1.8 to MetaFrame XP. What must you do to the XP farm to enable it to interoperate with MetaFrame 1.8? Run the XP farm in compatibility mode with a different farm name. Configure the XP farm with the same farm name as the 1.8 farm and run the XP farm in mixed mode. From Published Application Manager on the 1.8 master browser, choose farm scope and select the Interoperability Mode check box. Nothing. XP and MetaFrame 1.8 are fully compatible and do not need any special settings to work together.
5.	What transport protocols does ICA currently support? IPX SPX DLC NetBEUI

Answers

1.	þ B. Thinwire is correct because it is the portion of ICA that handles the graphical screen image. ý A, ICA, is incorrect because it contains thinwire. C, TCP, is incorrect because TCP is the lower level protocol that ICA and thinwire can ride on. In addition D, FTP, is incorrect because FTP is for transferring files.
2.	þ A, B, C, and D are all correct. A command is always included in every ICA packet. SecureICA is an encryption service so the encryption header would be included. Dial-up should always use compression and IPX is not a reliable protocol so a reliable header is added.
3.	þ D, DOS, is correct. Only the DOS client ýboth 16- and 32-bit versions) support running a text mode application in full-screen text mode on the client. ý Since D is correct, A, B, and C are therefore incorrect.
4.	þ B, Configure the XP farm with the same farm name as the 1.8 farm and run the XP farm in mixed mode, is correct. MetaFrame XP provides mixed mode to interoperate with legacy MetaFrame 1.8 farms during a migration. A requirement in mixed mode is that both farms have the same name. ý A, Run the XP farm in compatibility mode with a different farm name, is incorrect because XP does not have a compatibility mode, it has mixed mode, and again the farm names must match. C, From Published Application Manager on the 1.8 master browser, choose farm scope and select the Interoperability Mode check box, is incorrect because MetaFrame 1.8 has no facility to interoperate with XP. D, Nothing. XP and MetaFrame 1.8 are fully compatible and do not need any special settings to work together, is also incorrect because you do have to configure the XP farm to be compatible with MetaFrame 1.5.
5.	þ A, B, and D, IPX, SPX, and NetBEUI are all supported by the ICA client. ý C, DLC, is a mainframe protocol and is not currently supported by ICA, therefore it is incorrect.

Listing the Benefits of SpeedScreen Technology

6.	When was SpeedScreen 3 first available? WinFrame 1.5 MetaFrame 1.0 Feature Release 1 MetaFrame XP
7.	Your Citrix implementation is primarily for medical transcriptionists who work from home. Their primary application is a word processor and they are complaining that the text they type does not show up until several seconds after they type it. What feature of SpeedScreen would help alleviate this problem? Instant mouse feedback Predictive text entry Client side caching Repainting only changed areas of the screen
8.	How are SpeedScreen 3 settings configured? Per server Farmwide Per client Per application
9.	What application is used to configure SpeedScreen settings? Latency Reduction Manager Citrix Management Console Published Application Manager Citrix Server Administration
10.	You need to deploy the settings for SpeedScreen to all 80 servers in your farm. What directory needs to be copied to all the servers? %systemroot%\system32\ss3config %systemroot%\system32\ss3 %systemroot%\system32\SpeedScreen %systemroot%\system32\ThinWire

Answers

6.	þ C, Feature Release 1, is correct. Citrix first included SpeedScreen 3 technology in Feature Release 1 for MetaFrame 1.8. ý A, WinFrame 1.5, did not have a SpeedScreen feature set, thus it is incorrect. B, MetaFrame 1.0, included SpeedScreen 2, thus it is incorrect. D, MetaFrame XP, includes SpeedScreen 3 but it was not the first, thus it is incorrect.
7.	þ B. Predictive text entry is correct because it provides instant local text echo to allow users to see text as it is typed instead of waiting for the screen update from the server ýeven over high-latency connections). ý A, Instant mouse feedback would not satisfy the typists' need to see the text any faster, thus it is incorrect. C, Client side caching, only helps after an image has been displayed on the client screen. The character would still have to be sent to the server and return to be displayed. D, Repainting only changed areas of the screen, still would not help as this is a standard feature of ICA, thus it is also incorrect.
8.	þ D, Per application, is correct. All SpeedScreen 3 settings are configured on a per application basis. ý Since D is correct, A, B, and C are therefore incorrect.
9.	þ A, Latency Reduction Manager, is correct. All server-side SpeedScreen settings are controlled from the Latency Reduction Manager. ý Since A is correct, B, C, and D are therefore incorrect.
10.	þ A, %systemroot%\system32\ss3config, is correct. All Speed-Screen settings are saved in the %systemroot%\system32\ss3config directory and can be copied to all servers in the farm to deploy identical settings throughout. ý B, C, and D are not valid directories, therefore they are incorrect.

Discuss the Features of Independent Management Architecture

11.	IMA operates on which port? TCP 1494 UDP 1604 TCP 80 TCP 2512
12.	You are trying to present to management the reasons to upgrade to MetaFrame XP. While covering IMA, what are some of the points you would discuss? Session shadowing can now be logged. Administrative actions can be audited. Licensing information is distributed across all servers. All configuration data is stored in a central database.
13.	You are creating a large farm with servers in five geographical locations. You create a single farm and set up each location as a zone. By default, how many data collectors will there be? One Five Two Four collectors and one data store
14.	What three databases can support data store services? IBM DB2 Microsoft SQL Server Oracle Microsoft Access
15.	When setting up connections to the data store, a server can be configured one of two ways: direct connections and indirect connections. When setting up indirect connections, what is the biggest drawback? Slow performance Single point of failure Increased WAN utilization Requires multiple data stores

Answers

11.	þ D. 2512 is correct. IMA uses TCP port 2512 for all traffic. ý A, TCP 1494 is the port on which ICA session traffic operates, so it is incorrect. B, UDP 1604, is used for legacy ICA browsing, thus it is incorrect. C, TCP 80, is used for Web traffic, therefore it is incorrect.
12.	þ A, Session shadowing can now be logged, B, Administrative actions can be audited, and D, All configuration data is stored in a central database, are all correct. ý C, Licensing information is distributed across all servers, is incorrect because, like the configuration data, all licensing information is also stored in a central database.
13.	þ B, Five, is the correct answer. By default, each zone will contain one data collector. ý Since B is the correct answer, A and C are incorrect. D, Four collectors and one data store, is also incorrect because there will be actually be five data collectors and one data store. A data store does not function as a data collector.
14.	þ B, C, and D are correct. The default data store is the Microsoft Access database, but for larger installations, a more robust and powerful database such as Oracle or Microsoft SQL Server is recommended. ý A, IBM DB2, is incorrect. There is currently no support for DB15.
15.	þ B, Single point of failure, is correct. When using indirect connections, you must set up one server with a direct connection and point all other servers to it. This introduces a single point of failure if the single server fails. ý A, Slow performance, is not correct because the performance will not be affected. C, Increased WAN utilization, is incorrect because in most cases it will reduce WAN utilization by only one server if transmitting across the WANB to the data store. D, Requires multiple data stores, is incorrect because while it is possible to have multiple replicated data stores, using indirect connections would not require it.

Recognizing Listener Ports, Idle Sessions, ICA Sessions, and Client Device Licensing

16.	You are manning the help desk one morning and receive calls from users who have tried numerous times to get a connection to your MetaFrame XP farm. You have a large farm with 2000+ users and have plenty of capacity. It is about 9 A.M. so there are many users connecting to the farm at one time. You see that this behavior has become more and more common. What is the best immediate solution? Install additional servers Disable logons to the busiest servers Configure additional idle sessions Reboot all the servers in the farm
17.	What is the requirement to enable client device licensing? Use MetaFrame XPe Enable license pooling Run the farm in native mode Use a MetaFrame 1.8 server as the master browser
18.	To increase the count of idle sessions, what value in the registry must be incremented? IdleSessionCount IdleWinstationPoolCount NumIdlePortListeners IdleSessionTime
19.	Identify some of the possible states an ICA session can be in. ýChoose all that apply.) Neutral Active Listen Down
20.	What are the two types of connections that you may see a user being connected with? ICA HTTP RDP XML

Answers

16.	þ C, Configure additional idle sessions, is the best solution. Users are connecting faster than the idle sessions are recycling. Adding more idle sessions will allow users to connect at a faster rate and not get timeouts. ý B, Disable logons to the busiest servers, would not solve the problem because load balancing will be pushing users to the other servers already, thus it is incorrect. A, Install additional servers, would help the problem but it would not necessarily solve it, and you already have adequate capacity to service your users. This would be an unnecessary expense that would not be a complete fix, thus it is not the best solution and is incorrect. D, Reboot all the servers in the farm, would not only cause all users to lose the connections they have, it would probably increase the rate of timed-out connections as all the users that have trickled in over the last hour will suddenly be attempting to reconnect all at once. Not to mention, you may lose your job. This is not the best solution and therefore incorrect.
17.	þ B, Enable license pooling, is correct. Client device licensing prevents a single client from consuming multiple licenses if connecting to multiple servers to run applications. To enable it, you must have licenses pooled and the license the client acquires must be a pooled license. ý A, Use MetaFrame XPe, is incorrect because license pooling is also available in other versions of MetaFrame. C, Run the farm in native mode, is incorrect because client device licensing also works in mixed mode. D is incorrect because the use of a MetaFrame 1.8 server as the master browser is not allowed in a mixed or native mode MetaFrame XP deployment.
18.	þ B, IdleWinstationPoolCount is correct. This value, located in the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server, controls the number of idle sessions ýor Winstations) the server maintains. Keep this number as low as possible because each idle session requires system resources. ý A, C, and D are not valid values and therefore are incorrect.
19.	þ B, C, and D are correct. ICA sessions can be in one of five states: Active, Listen, Idle, Disconnected, and Down. ý A, Neutral, is not a valid state for ICA connections, thus it is incorrect.
20.	þ A, ICA, and C, RDP are correct. The two types of connections currently supported by Terminal Services and MetaFrame are ICA and RDP. ý B, HTTP is used for Web browsing not ICA connections, thus it is incorrect. D, XML, is for ICA service location, not connection, thus it is also incorrect.
