Understanding the Citrix Management Console
| 1. | You have the CMC installed on your Windows 2000 professional machine at a WAN site to administer a farm at your corporate data center. You configured your CMC for auto-refresh last week before leaving for vacation. After returning from vacation, you notice your workstation is now locked, with the CMC still running. While you were away, users had been complaining of slow response times within their ICA sessions. What could have caused the sudden decrease in performance?
| |
| 2. | Which of the following will increase the performance of your servers?
| |
| 3. | The CMC is a Java-based extensible utility for managing server farms. Which of the following platforms will the CMC NOT run on?
| |
| 4. | Which of the following are the minimum requirements of the CMC?
| |
| 5. | You are planning to install a small five-server farm. Which system or solution is the most efficient and cost-effective way to create the data store necessary for storage of server farm data?
| |
| 6. | Your server farm's data store is SQL based. You are bringing a new server online next week. You configure its access to the data store as indirect. What is the primary limitation of this type of access?
| |
Answers
| 1. | þ B. Setting Data Refresh on your CMC causes a significant increase in traffic on your network. When the console is running, auto-refresh traffic can become cumbersome on the network. ý A is incorrect because merely having the CMC installed on your machine does not cause an increase in traffic. C is incorrect because if packets were being dropped on your network regularly, users would be getting disconnected from their sessions. D is incorrect because a new domain controller only affects authentication, not the performance of an ICA session. |
| 2. | þ A. Configuring a reboot schedule on each of your MetaFrame servers will allow the system to free up valuable resources due to memory leaks, as well as increase overall performance of your server farm. ý B is incorrect because allowing users access to the CMC will not increase the performance of your servers. C is incorrect because uninstalling the CMC on each MetaFrame server is impossible and impractical. D is incorrect because adding Citrix Administrator accounts will not affect the performance of the servers in the farm. |
| 3. | þ C. The CMC cannot run on a Windows 98 machine. ý A, B, and D are incorrect because the CMC can be installed and run on all Windows 2000, NT4, and MetaFrame servers. |
| 4. | þ A. The CMC requires 32MB of RAM and 25MB of disk space in addition to the operating system requirements. ý B, C, and D are incorrect because it is only necessary to have 32MB RAM and 25MB disk space to install the CMC. |
| 5. | þ A. Using Access is a simple, cost-effective solution, since Access and all its necessary ODBC drivers are components of the base operating system in Windows-based systems. ý B and C are incorrect because SQL and Oracle require additional ODBC drivers to be installed on the server for access to the data store database. Additionally, you would need a dedicated SQL or Oracle server because you cannot install MetaFrame on the same system as an Oracle or SQL install. D is incorrect because Excel is not a database, and the data store only supports databases in the form of SQL, Oracle, or Access. |
| 6. | þ A. Although indirect access saves the administrator from having to install the ODBC drivers on each server in the farm, the intermediary server, which acts as the go-between for the data store, becomes the single point of failure in the server farm. If the intermediary goes offline, users will be unable to connect to the servers configured for indirect access. ý B is incorrect. If you install the ODBC drivers on a MetaFrame server, it can use direct communication with the data store. C is incorrect because, although indirect access to the data store is possible, it is not a fault-tolerant solution. D is incorrect because it is not necessary for the CMC to be running in order for a server to communicate with the data store. |
Identifying Published Application, Server, and Citrix Administrator Properties
| 7. | Which tab on the server properties allows administrators to disable logons to the server?
| |
| 8. | Which setting within the CMC allows a Citrix Administrator, user, or group to have only view permissions within the CMC?
| |
| 9. | In addition to the ICA display settings on the properties of the server farm, which command-line utility allows the administrator to increase the performance of ICA sessions by tweaking the display settings of ICA clients when they connect to the server farm?
| |
| 10. | You are an administrator of a large MetaFrame server farm. You were out on vacation last week when a patch was applied to the servers to address a printing issue. When you arrive at work this morning, your manager informs you that some users are still having difficulties printing. Your first course of action is to verify that every server in the farm did indeed receive the patch. What tab within Server Properties allows you to view this information from the CMC?
| |
| 11. | As the administrator, you want to increase the organization of applications within Program Neighborhood on your clients by using folders. Using elements visible in Program Neighborhood, how can you do this?
| |
Answers
| 7. | þ C. The MetaFrame settings tab on the server properties allows administrators to disable logons to the server. Disabling logons to a particular server is wise when an administrator is installing service packs, applications, or performing any other type of system maintenance on MetaFrame servers. Disabling logons to the server will prevent any users from connecting to the server until maintenance is complete and the administrator unchecks the Disable Logons box, allowing logons to that particular server. ý A is incorrect because the Interoperability tab is present and used solely for configuring communications between MetaFrame 1.8 and MetaFrame XP servers. B is incorrect because the Information tab displays operating system, service pack, MetaFrame version, TCP/IP address, NetBIOS address, and IPX/SPX address information. D is incorrect because the Published Applications tab contains a listing of all the applications published on the selected server. |
| 8. | þ A: When configuring Citrix Administrator accounts, you have the option to allow read-only or read-write access to the Citrix Management Console to the account. Read-write access allows Citrix Administrators to make configuration changes within the console, while read-only permission allows Citrix Administrators to view the current configuration, but not to make changes. ý B is incorrect because it allows administrators to make changes to the settings within the console. C and D are incorrect because these options do not exist within the CMC. |
| 9. | þ B. TWCONFIG is a command line utility which allows the administrator to make changes to the ICA display settings on each particular server. ý C is incorrect because the CHFARM command-line utility is used to change the membership of a server from one server farm to another. A is incorrect because CTXXMLSS changes the XML service port number. D is incorrect because CLICENSE allows administrators to maintain licenses from the command prompt. |
| 10. | þ C. Each server maintains a list of hotfixes installed, which can be viewed on the Hotfixes tab within Server Properties. ý A is incorrect because the ICA Display tab has information related to the appearance of an ICA session. B is incorrect because the MetaFrame Settings tab contains settings for ICA browser, enabling logons, enabling shadowing, and Citrix XML port configuration, not hotfixes. D is incorrect because there is no such tab called Server Farm within the Server Properties. |
| 11. | þ B. The Program Neighborhood Folder option within the Program Neighborhood Settings tab allows the administrator to place applications within folders that are visible within the Program Neighborhood of the ICA client. ý A is incorrect because creating a new folder beneath the Applications object will organize applications in folders, but these folders are visible only to the administrators using the CMC. C is incorrect because the ICA Client Options tab does not contain an option for configuring folders within Program Neighborhood on the ICA Client. D is incorrect because there is no tab named Folders within the CMC. |
Administering the Citrix Management Console
| 12. | You have installed a RAS server to allow users to gain access to the network. You dial into the network via the RAS server to test the user's ability to launch their ICA sessions once they are authenticated to the network. After launching the ICA session, you receive an error that a Citrix server cannot be located. What could be the problem?
| |
| 13. | When your users who reside in remote offices across WAN links print large print jobs, all users at the remote site end up complaining about poor performance. How can you ensure the performance of ICA sessions across the WAN link and still provide print services?
| |
| 14. | Which of the following tasks allows the administrator to terminate a user's session while closing all processes on the server and freeing up valuable memory resources?
| |
| 15. | Which service improves reliability and performance by allowing the administrator to install identically configured applications to each server in the farm?
| |
Answers
| 12. | þ A. When the server farm is configured to have RAS servers respond to ICA client broadcasts, users who access the network remotely using pre 6.0 ICA Clients will be able to contact the server farm and connect to published applications. It is not necessary to possess administrative privileges in order to launch an ICA session from a RAS connection. There is no Enable Logons setting. ý It is not necessary to log on to a RAS server with an account that has administrative privileges in order to access the server farm, therefore B is incorrect. Although it is necessary to enable logons to the server, the error message stated that a Citrix server could not be located. Therefore, the issue concerns communicating with the server farm, not with authenticating. Thus, C is incorrect. It is possible to remotely access a server farm in a number of ways, including RAS dialing and ICA dial-in, making D incorrect. |
| 13. | þ C. The CMC offers printer bandwidth management for situations in which ICA clients are experiencing poor performance when large print jobs traverse the WAN link. Printer bandwidth management is on a per-server basis. You can fine-tune the bandwidth allowed per ICA session for printing by using the Printer Bandwidth setting, which can be located by either choosing Printer Management in the left pane and then choosing the Bandwidth Management tab in the right pane or using the Printer Management tab within server properties. ý B is incorrect because limiting the number of users who can connect to the server will not solve the problem. The bottleneck is on the WAN link, not the server. A is incorrect because adding static routes will not solve the problem due to the fact that routing has already been established ýor else your users would not be able to connect to the server farm to begin with), and is therefore not an issue. Replicating a printer driver across the farm will not improve overall performance, therefore D is incorrect. |
| 14. | þ A. When an administrator chooses to log off a user, all the programs and processes associated with the ICA session are closed in a controlled fashion, and valuable resources used in the ICA session, such as RAM, are recycled. ý B is incorrect because disconnecting sessions allows administrators to leave the programs and processes of a particular ICA session open on the server so that the user can reconnect to the session at a later time. C is incorrect because resetting an ICA session can cause data loss. Therefore, it should be the last course of action, only done when the session cannot be logged off or reset. D is incorrect because shadowing a user only allows the administrator to remotely monitor and manage the session. |
| 15. | þ B. Installation Manager is an add-on product that allows the administrator to package preconfigured applications and schedule deployment of the packages to servers within the server farm. ý C is incorrect because resource Manager is used to keep a count of how many instances of specific applications are running in the server farm. The Application Publishing Utility is used when an administrator initially publishes an application within a server farm. Therefore, A is incorrect. D is also incorrect because the replication service is not an option within MetaFrame. |
