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.

Using Event Viewer and System Information

1.	In the Event Viewer, what three pieces of information about an event are key in locating the cause and resolution of a problem? Date, Time, and Type Username, Computer Name, and Source Source, Event ID, and Description Time, Computer Name, and Type
2.	What five types of events are recorded to the event logs? Information, Warning, Error, Successful Audits, and Failed Audits Application, Security, System, Directory Service, and File Replication Source, ID, Description, Username, and Computer Name Daily, Weekly, Monthly, and Yearly
3.	What does Citrix recommend the Event Log's maximum size be set to? 512KB 256KB 1024KB 2GB
4.	Connect using RAS and open the Event Viewer on the remote system. Right-click Event Viewer (local) and select Connect To Another Computer. Open the Event Viewer and from the Action drop-down menu, select Connect to a remote computer. Add the remote computers you wish to monitor to the Event Viewer (local) tree.
5.	Jack has called his software vendor support line for help in troubleshooting an error he's receiving. The support technician wants to know what type of system Jack is using, the BIOS version, OS build, installed RAM, and other basic system configuration information. What is the best way Jack can quickly get this information to the support tech? Locate the documentation that came with his system and fax it to the technician. Right-click System Summary in Information Tools. Save the information to a text file and e-mail it to the tech. Quickly make a list of all the information the tech wants; then check system documentation and configuration files for the answers. Type this into an e-mail and send it to the tech. Promise the tech the information will be forthcoming and assign the task to your Jr. Administrator.
6.	The System Information Tool can be used to Modify or add a new component to your system Display system configuration settings Remove or disable device drivers Connect to another computer
7.	Diane has installed a new USB port on her computer but it doesn't appear to be functioning. Where can she look to see if there's a problem with the new port? (Select all that apply.) The Event Viewer System Information | Hardware Resources | Conflicts | Sharing Device Manager Performance Monitor
8.	Scott, the new Jr. Administrator, has been monitoring the Event Logs on the Sales server farm. For several days now an event warning has been logged that doesn't make any sense to him. It doesn't seem to point to a particular system component. He's worried that it could escalate and become a real problem if he doesn't discover what is causing it. What can Scott do to find out what the event means? Call the Sr. Administrator who is away on vacation and ask for assistance. Keep monitoring the event and hope that nothing further happens before the Sr. Administrator gets back. Check the Microsoft and Citrix Knowledge Bases for any reference to the Event ID and description. Wait until someone calls to complain of a problem that is occurring around the same time.
9.	How can you display all the pertinent details about a device including driver version, IRQs, and I/O? Open Device Manager and double-click the device. Open System Information and go to the Component Folder. Right-click the device to view its property sheet. Locate the device's documentation. Use Explorer to navigate to the device's software installation folder. Look for .txt or .inf files and read through them.
10.	In Windows 2000, where can the environmental variables be found? In the Control Panel under System. Under Administrative Tools/System. In System Information Tools under the Software Environment Folder. In Start | Programs | Accessories | System Tools.

Answers

1.	þ C is the correct answer. The Source can lead you to the component that reported the event, while the Event ID and Description will help you track down the appropriate Knowledge Base article for a resolution or explanation. ý Answers A, B, and D are all types of information found on the Event Properties sheet, but are not as important in the troubleshooting process as the items in answer C.
2.	þ A. The five types of events recorded in the event logs are Information, Warning, Error, Successful, and Failed Audits. ý B lists the types of logs that Event Viewer can monitor, while answer C provides only one of the correct answers. D is totally fictitious.
3.	þ C. Citrix recommends setting the Event Log's maximum size to 1024KB and to overwrite as needed. ý A is the default log size on Windows 2000, B is smaller than the default size and would fill up quickly in most environments, and D is overkill, no Event Log should ever get that big.
4.	þ B. As long as the remote workstation or server has an account in the domain, or is in a trusted domain and is currently on the network, you can right-click Event Viewer (local) and select Connect To Another Computer. ý A is possible, but not the best choice. C is incorrect because there is no option to Connect To Another Computer within the Action drop-down menu. D is incorrect because you cannot add items to the Event Viewer (local) tree.
5.	þ B is the correct answer. The System Summary provides the basic system configuration information the tech is looking for, and it's the quickest, most accurate way to provide it. ý A is incorrect because the original system documentation may not provide all the details the tech needs and it most likely will not be up-to-date. C is possible but definitely not the quickest and easiest way to get things done. D is also possible if Jack doesn't need a resolution to his problem any time soon.
6.	þ B is correct. The System Information Tool can only be used to display the configuration settings because it is read-only. ý A is incorrect because you cannot add or modify settings in the System Information Tool. These tasks can be performed in Device Manager. C is also incorrect for the same reason; use the Device Manager to uninstall or disable device drivers. D is also false. You cannot connect to another computer through the System Information Tools, but you can through System Tools.
7.	þ A, B, and C are all correct. Diane can check the Event Viewer to see if an error report has been logged. She can also check for IRQ conflicts under System Information | Hardware Resources | Conflicts | Sharing, and C is correct because a device that isn't functioning properly will also show up in the Device Manager displayed with a warning or error symbol. ý D is incorrect because Diane can look at the Event Viewer, the System Information | Hardware Resources | Conflicts | Sharing, and the Device Manger, but not the Performance Monitor, to determine if there's a problem with the new port.
8.	þ C is the best answer. Even if there is no source that points to a particular device or component, the Event ID and/or the description of the event can usually locate a Knowledge Base article that will explain the event. ý While A is a possibility, it wouldn't look good for Scott, and the Sr. Administrator probably wouldn't like being called off the beach. B is also a possibility. Some warnings are innocuous and never really turn into a problem, but there's always the chance that it might. It's better to be safe than sorry. D is also a possibility but again, it wouldn't be in Scott's favor to wait until someone complains. Finding the answer before a problem occurs could make him the hero.
9.	þ B. The Components folder lists all the components that may or may not be installed on your system. If you right-click an installed component, it will open its Property Sheet which provides all the pertinent details. ý A is incorrect because the key word here was 'display.' From within the Device Manager, you can install, uninstall, and modify settings for a device. C is incorrect because the original documentation may not be the current driver version. D is also incorrect as the driver installation may not have created a folder.
10.	þ C is correct. The Software Environment folder lists the environmental variables, network connections, running task, and other useful information. ý A is correct for Windows NT, but incorrect for Windows 2000. B is also incorrect. Environmental variables are not located in the Administrative Tools folder. Although there are some useful utilities under Accessories | System Tools, environmental variables is not one of them.

Managing Resource and Citrix Network Manager and Troubleshooting Network Monitor

11.	What are two tools included with Windows 2000 Server and MetaFrame XPe that can facilitate developing a system baseline? Event Viewer and System Information Tool System Information Tool and Connection Manager Citrix Resource Manager and Performance Monitor Citrix Load Manager and Citrix Resource Manager
12.	A server in the server farm Maurice manages has been experiencing some performance problems lately and he has decided to use Resource Manager to help him find out why. He suspects that there may be a hardware problem or a faulty device driver. What object and associated metric can he monitor to confirm this? Maurice should monitor the Network Interface Bytes Total/sec. The Terminal Services, Active/Inactive Sessions will provide the information needed. The problem is most likely a processor problem, so Maurice should check the %Processor Time metric. Because he suspects it is a hardware or device driver problem, Maurice should monitor the Processor %Interrupt Time metric.
13.	MetaFrame XP MetaFrame 1.8 for Windows 2000 MetaFrame XPa MetaFrame XPe
14.	Randy has decided to install Citrix Network Manager on his MetaFrame XPe server. He has made sure that the hardware exceeds the necessary minimums for Windows 2000 and MetaFrame XPe and he has applied all the necessary service packs and hotfixes. In preparation for the install, Randy logs in as Administrator and makes sure there are no applications running or users connected to the server. He places the Network Manager disc in the CD-ROM drive, uses Add/Remove Programs for the install, and selects the Tivoli NetView plug-in. The installation begins, but ends abruptly with an error message. What could be wrong? Randy has forgotten to log in as Administrator. He does not have Tivoli NetView installed on the server. He has not installed SNMP services. You cannot install Network Manager on a MetaFrame XPe server.
15.	What needs to be installed on Windows NT 4.0 Terminal Server Edition prior to installing Resource Manager? The SNMP services The Microsoft Access runtime version MDAC 2.51, SP1 MetaFrame 1.8.
16.	Susan has been monitoring her server farm with Resource Manager for several weeks now. Everything has been good so far; all the indicators are green for her servers. Next week, due to corporate reorganizing, her location will house another small division and its employees. The new employees will be connecting to her server farm and she's not sure whether she has enough resources on her servers to accommodate the new users. What objects and metrics can she monitor in Resource Manager to help her decide? (Select all that apply.) Network Interface, Bytes Total/sec Processor, %Interrupt Time Processor, %Processor Time System, Context Switches/sec
17.	Diane wants to find out what applications her users are running most often and how many instances of each they are running. How can this be accomplished? Diane should create an online survey and distribute it to all her users. Diane should use Resource Manager to produce Current User Reports. The reports will display the users, the applications they are running, and the number of instances of each that are running and who is running them. Diane should use Network Monitor to trace network packets to see who is running the applications. Diane should use System Information Tool to monitor Applications.
18.	Citrix Network Manager can use the SNMP consoles of which two third-party management solutions? (Select all that apply.) Tivoli NetView 5.1.2 or later Resource Management Services 1.0b HP OpenView Network Node Manager 6.1 or later Bline Extra Management Services
19.	John has been noticing that his network slows to a crawl during the afternoon. He's used Resource Manager to monitor the Network Interface metric and found there is usually one server that appears to be generating and receiving a lot of network activity, but it is seldom the same server from day to day. What could be the problem and how can John track it to its source? (Select the best answer.) John's servers are load-balanced, that would explain why it is never the same server producing the alerts in Resource Manager. A high count for Network Interface, Bytes Total/sec could indicate the server is engaging in a high amount of activity. A likely reason could be that a user is either up/downloading files from the Internet or playing Internet online games. John can run Network Monitor and enable filtering on the Internet proxy server if this is true. He can then trace the packets back to the originating workstation and user. John suspects that a user is playing online Internet games every afternoon. The reason it is seldom on the same server is because the user is attempting to escape detection by logging in to a different server each day. John will use Resource Manager to run Current User reports to discover who it is. John has assembled a task force that will covertly visit each user's desk during the afternoon hours. The user in question will not know who the spies are and will not take precautions to prevent detection. The user has been logging in to a different server each day in an attempt to prevent detection. John suspects that the reason has something to do with the Internet and will enable filtering in Network Monitor to trace packets to and from the Internet proxy server.
20.	What type of network interface card does Network Monitor require to function? One that can run in Liberal mode One that can run in Promiscuous mode One that runs extremely fast One that can work with another NIC in tandem

Answers

11.	þ C. Both Citrix Resource Manager and Microsoft's Performance Monitor can facilitate developing a system baseline. Resource Manager was created specifically for MetaFrame XP and is more server-base aware. ý A is incorrect because although both the Event Viewer and System Information Tool are good tools for monitoring and troubleshooting, they have no real-time or historical monitoring capabilities. B is also incorrect because the Citrix Connection Manager has nothing to do with performance monitoring and System Information Tool does not provide real-time or historical information. D is partially correct. Resource Manager could help, but the Citrix Load Manager does not monitor system performance or provide real-time or historical information.
12.	þ D. The Processor %Interrupt Time metric, if consistently high, can mean that there is a hardware problem or a faulty device. ý A is incorrect because the Network Interface Bytes Total/sec monitors the network activity the server is generating and receiving. B is incorrect because the Terminal Services Active/Inactive Sessions pertains to users who are currently logged in and either active or disconnected. C is close-it is most likely a processor problem, but %Processor Time implies there are too many users on the server or that a rogue program is running.
13.	þ D is correct. Citrix Resource Manager is available only with MetaFrame XPe and it cannot be purchased separately. ý A is incorrect because MetaFrame XP is the basic solution and does not include Resource Manager. B is also incorrect because MetaFrame 1.8 did not include Resource Manager. However, Resource Management Services (RMS) could be purchased separately. C is also incorrect. Resource Manager is only available with MetaFrame XPe.
14.	þ C. He has forgotten to install SNMP services on the server. ý A is incorrect because Randy did log in as Administrator. B is also incorrect because Tivoli NetView does not need to be installed on the server, only the plug-in needs to be installed. D is incorrect as well because you can install Network Manager on a MetaFrame XPe server.
15.	þ C is the correct answer. MDAC 2.51, SP1 must be installed prior to installing MetaFrame XPe or Resource Manager. ý A is incorrect. SNMP services do not need to be installed to run Resource Manager. B is incorrect because Resource Manager installs the runtime version of Access automatically. D is also incorrect because MetaFrame 1.8 does not need to be installed.
16.	þ A, B, C, and D. Network Interface, Bytes Total/sec can tell her if her servers are generating or receiving high levels of activity. This could mean there are too many users connecting at one time. If Processors, %Processor Time is consistently high, it could indicate there are too many users on the system, while System, Context Switches/sec can indicate that there are too many users on the system competing for processing time. B is also correct because the Processor, Interrupt Time can indicate the server is too busy.
17.	þ B is the correct answer. Diane should use Resource Manager Current User reports to monitor the users, applications, and instances. ý A is not the correct answer, but if Diane had no other tools at her disposal, she could do this. C is incorrect because Network Monitor can trace packets based on protocol, sending/receiving computer, and various other variables but cannot tell her what applications are running or how many instances there are of each. D is also incorrect because System Information Tool can display installed applications but cannot provide information regarding who is using the applications or how many instances of each are running.
18.	þ A and C are correct. Tivoli NetView 5.1.2 and HP OpenView Network Node Manager are both supported by Citrix Network Manager. ý B is incorrect as this is the earlier version of Resource Manager used with MetaFrame 1.8 and is not a third-party solution. D is incorrect, as it does not exist.
19.	þ The best answer is A. John's servers could be load-balanced, which would explain why the activity is seldom on the same server. If Resource Manager is reporting high metrics on Network Interface, Total Bytes/sec, this is a good indication that the server or servers are generating and receiving high traffic. By using Network Monitor and enabling filtering on the Internet Proxy server, John can discover which workstation the packets are being sent to and from. ý B is incorrect because Resource Manager Current User reports will only show that the Internet browser is being used, not the games which are running on a server somewhere on the Internet. C is the Gestapo method and may work, but there really must be an easier way. D is partially correct, but a more plausible reason for the movement from server to server is load-balancing.
20.	þ B is the correct answer. The network interface card used to run Network Monitor must support Promiscuous mode. ý A is incorrect as there is no Liberal mode. C is also incorrect, although it would be wise to use the interface cards that support 100MB transfer rates or more, and D is incorrect because it is not required that there be two network cards for Network Monitor to work. If there are two cards, you must select the network to be monitored before the console will open.
