Identifying Software and Hardware Requirements for MetaFrame XP

1.	What operating systems can MetaFrame XP be run on? (Select all that apply.) Mac Linux Windows NT 4.0 Terminal Server Edition The Windows 2000 Server family
2.	Joe will be installing a MetaFrame XP server to provide Microsoft Windows 2000 for a small department of ten clerical users. He is given a server that had been used in another department prior to an upgrade. The server is a 200MHz PIII with 128MB of RAM and 1GB of disk space. All the clients will be PCs running Windows NT and using TCP/IP. His boss would like him to use the Windows 2000 operating system. What must he do prior to installing MetaFrame XP? Install Windows 2000 Server and TCP/IP, then install MetaFrame XP and configure. Install Windows 2000 Server, TCP/IP, and Terminal Services prior to installing MetaFrame XP. Install the Citrix 32-bit client on the users' PCs. Upgrade the RAM to 512MB, add an additional hard disk with at least 1GB of space, and install Windows 2000 Server, TCP/IP, and Terminal Services. Install MetaFrame XP and the Citrix ICA clients on the users' PCs. Add an additional hard disk with at least 1GB of disk space, install Windows 2000 Server, TCP/IP, and Terminal Services then install MetaFrame XP. Install the ICA clients on the user's PCs.
3.	You plan to install Citrix NFuse to publish applications. What additional software components must you install first? (Select all that apply.) ActiveX Java Virtual Machine Internet Information Server Anti-virus software
4.	Jackson has installed Windows 2000 Server on a PIII 400MHz machine with 1GB of RAM and a 10GB hard disk. He runs DCPROMO and configures DNS, WINS, and DHCP. Later, he decides he will make this a MetaFrame XP server, so he installs Terminal Services and MetaFrame XP. He logs in to the server as administrator and, since all appears okay, he decides to test the server as a user from a client machine. He installs the Citrix ICA client on a PC running Windows 2000 Pro. He then connects to the server and attempts to log in, but is unable to. What could be the problem? The server doesn't have the minimum requirements to support MetaFrame XP. His account has been locked out. He has installed MetaFrame on a domain controller and does not have Log On Locally permissions. He has configured his ICA connection incorrectly.
5.	What component must be installed prior to installing MetaFrame XP if Novell Netware is be used in the same environment? IPX/SPX The Netware client Java Virtual Machine TCP/IP
6.	How much RAM is required for MetaFrame XP and IMA? 80MB 64MB 280MB 512MB
7.	The ICA protocol runs at what layer of the OSI model? Network Layer Presentation Layer Data Link Layer Application Layer
8.	What percentage of application processing is done on the server? 10 percent 25 percent 80 percent 100 percent
9.	How much bandwidth does the ICA protocol use on average? 5 Kbps 30-40 Kbps 8 Kbps 10-20 Kbps
10.	What is the recommended amount of RAM required for each Power User connecting to a MetaFrame XP server? 10MB 15MB 8MB 12MB
11.	Scott oversees six MetaFrame XP servers and would like to find a way to monitor the servers without going into the data center and logging in to each one. What can Scott do to ease his administration tasks? Use Event Viewer to monitor all servers. Install Citrix Management Console on a Windows 2000 Pro PC and monitor all servers from there. Purchase a third-party add-on to monitor all servers. Install Citrix Management Console on the servers.

Answers

1.	þ C and D. MetaFrame XP can be run on Microsoft Windows NT 4.0 Terminal Server Edition, Service Pack 4 or later and Microsoft Windows 2000 Server, Advanced Server, or Datacenter Server, Service Pack 2 or greater. ý A and B can run on the Citrix ICA client only.
2.	þ C. The server Joe was given did not have the minimum amount of RAM necessary to install Windows 2000 Server, nor did it have the minimum disk space needed, so he had to upgrade the hardware on his server before installing Windows 2000 Server. ý In answer A, the installation would have failed because there were not enough resources and Terminal Services would need to be installed. Answer B has Terminal Services installed but still needs additional RAM and disk space. In D, Joe is still lacking the necessary RAM to install Windows 2000 so his installation would not be successful.
3.	þ B and C. Both Microsoft Java Virtual Machine ýJVM) and Microsoft Internet Information Server, version 4.0 or later must be installed. ý Neither answers A nor D are needed for NFuse.
4.	þ C. After Jackson installed Windows 2000 Server, he ran DCPROMO, promoting his server to domain controller status. By default, users cannot log in to the domain controller unless they have Log On Locally permissions. ý A is incorrect because his server does have enough resources to run Windows 2000 Server and MetaFrame. Answer B is also incorrect because he would have received a message telling him his account had been locked out. Answer D is incorrect because he was able to connect to the server. If he hadn't configured the connection correctly, he would never have gotten to the login screen.
5.	þ B. The Novell Netware Client must be installed prior to installing MetaFrame XP. ý A, C, and D can be installed afterwards, though it is a good idea to plan ahead and install all necessary protocols in advance.
6.	þ B. 64MB of RAM is required to run MetaFrame XP and IMA. ý A, C, and D are all greater than the amount required, thus they are incorrect.
7.	þ B. The ICA protocol runs at the Presentation Layer of the OSI model. ý A, C, and D are incorrect because Citrix ICA protocol uses other protocols to manage transport and connection.
8.	þ D. 100 percent of the processing is performed on the MetaFrame XP server. Only the mouse clicks, keystrokes, and screen updates travel between the server and the client. ý A, B, and C are all incorrect, as they would put a portion of the processing on the client.
9.	þ D. Citrix ICA uses an average of 10 to 20 Kbps and is optimized for connections as low as 14.4. ý A and C are incorrect as they are less than the actual amount consumed, while answer B is far more than the amount consumed.
10.	þ C. Each Power User connecting to the MetaFrame XP server will require at least 8MB of RAM, while each Typical User will require at least 4MB of RAM. ý A, B, and D are all incorrect, as they exceed the recommended amount of RAM that each Power and Typical User would require. Exceeding the recommended amount is not a bad thing, because more is definitely better, but it is not the correct answer in this case.
11.	þ B. Scott can install the Citrix Management Console on any Windows NT or Windows 2000 Pro PC and monitor all the MetaFrame XP servers from there. ý A is incorrect because the Event Viewer will only allow you to view event logs on all the servers in a domain, but not monitor performance. C is not necessary as Citrix Management Console is part of MetaFrame XP. D is incorrect because installing the Management Console on each server is unnecessary.

Server Planning and Sizing

12.	The MetaFrame XP server you installed for the clerical department has done so well that the engineering department has decided they too wish to lower their total cost of ownership by installing a MetaFrame XP server. They have chosen to spend their budget on a new server ýwith the proper resources to support their group) rather than upgrade or buy new PCs. Their specialized engineering software is updated frequently and always needs more resources than the last update. It is your job to make sure they spend their money wisely and purchase a server that will support the group and run their programs in the same manner they are accustomed to on a PC. What must you do to ensure this? Purchase a server that covers the minimum resources needed to run Windows 2000 Server and MetaFrame XP. Make sure their PCs have enough resources to run the Citrix ICA client software, and train the users on how to work efficiently in their new environment. Purchase a server with 256MB of RAM, a 5GB hard disk drive, and install TCP/IP as your network protocol. Plan out your installation beforehand, adding together the resources required by the operating system, MetaFrame XP, and the applications that will be run off the server. Begin by planning your installation. Find out what resources the operating system and MetaFrame XP require. Talk to the users in the engineering department and find out how they are accustomed to working. If they are Typical Users, using only one application at a time and not doing anything too tricky, add at least an additional 4MB of RAM for each. If they are Power Users who have several applications running at once and a good grasp of Windows concepts, add an additional 8MB of RAM for each. Add at least an additional 100MB of disk space for each user. Evaluate the amount of resources required by the applications that will be run. The applications are currently installed on the users' PCs so you could run them and check Task Manager for the amount of RAM needed. The documentation that came with the software should tell you the amount of disk space and RAM required for each, as well as the processing speed. Check to find out if the users will all be accessing the server from the LAN, or if there are any remote users accessing from a WAN, dial-up connection, or RAS. When you have gathered all the information, do the math and find what your minimum requirements will be to support the users and application load placed on the server. To these figures, add additional resources to ensure the users' experience is comparable to their experience on a PC.
13.	What databases are supported for a MetaFrame XP data store? ýChoose all that apply.) Oracle Microsoft Access Microsoft SQL Paradox
14.	What type of memory is recommended for the server? EDO RAM ECC RAM VRAM Flash RAM
15.	Diane has been called in as a consultant at a company that has just implemented a server-based computing environment using Windows 2000 Advanced Server and MetaFrame XP. An employee who has since left the company did the installation and no one can figure out why their servers seem to be running so slow. Users say that the performance is okay part of the day, but later slows to a crawl, especially in the afternoons. What could be the possible causeýs) and what can be done to correct the situation? ýSelect all that apply.) The users' PCs need more RAM. Upgrade PCs to 128MB of RAM. Older DOS programs are running on the server during afternoon hours. Place DOS programs on a separate server or find updated 32-bit software. Users are checking the stock market with streaming video tickers. Create policy to restrict streaming video. The server's anti-virus software is set to scan in the afternoons. If a complete scan is necessary, set the time for later at night when users are not logged in.
16.	Evelyn is in the planning stages of implementing a MetaFrame XP server farm. She has gathered information on the users, applications, and hardware, and feels she has identified the resources necessary to equip her servers for MetaFrame XP so they will perform optimally. What else must she size and decide upon before she is finished with the planning stage? Clients Upgrading user PCs Which database she will use for the data store and where it will be placed What applications to run
17.	Randy has been asked to assist in planning a new MetaFrame XP server farm for the credit department. It is essential that the servers be available 24/7, thus they are looking to Randy to suggest ways to improve availability and reduce chances of downtime. What are some of the options Randy can suggest? ýSelect all that apply.) Use Citrix load balancing Use redundant parts such as controllers, power supplies, and NICs Use RAID with hot-swappable drives Keep an online, hot spare server
18.	Maurice has been hired as a consultant for XYZ Company. They have decided to move to a server-based environment and want Maurice to spec out the systems they will need to order for the new servers, then assist with the installation and testing. Maurice is not familiar with the users, applications, or environment. What should Maurice do to judge the amount of RAM and disk space necessary, in addition to that required for the operating system and MetaFrame XP? Ask for a list of users and a list of the applications to be installed on the servers, then add together total users and applications and multiply by 16. Add up the users and multiply by 8. Ask for a list of the users slated for the servers, as well as a list of the applications that will be installed. Visit with as many users as possible to discover what they do and how they will use the server. Categorize each user as a Power User or a Typical User. Add up the Power Users and multiply by 8 to get the amount of RAM needed for each Power User. Add up the Typical Users and multiply by 4 to get the amount of RAM necessary for each Typical User. Add 100MB of disk space for each user as well. Research each application to discover the resources needed to run them. When all the data has been collected, add these figures to the amount of RAM and disk space needed by the operating system and MetaFrame XP to get the minimum requirements. Add 128MB of RAM for each application and 64MB of RAM for each user.
19.	Ken has decided to start his own small business and has obtained a loan that will cover most of the equipment he needs to begin. He has purchased two servers with enough resources to support the applications he will run, as well as the number of users he will employ. Next, Ken will need client machines for the employees, but he's running short on funds and can't afford the new PCs he planned on. He does have several older PCs around, but they don't have enough resources to run the software they will be using. What can Ken do to get his business up and running without having to acquire more funds? ýSelect all that apply.) Purchase as many PCs as he can with the money he has left, and create local accounts on each machine so the users can share PCs. Have the employees work in shifts so there are enough PCs for each user on each shift. Load the older PCs with the appropriate Citrix ICA client and configure. Instead of purchasing PCs for each user, purchase thin client devices.
20.	The Management at Acme Widget Corporation has decided to merge two of their divisions into one business unit. They also are looking to lower their TCO and are thinking of changing from a traditional client/server environment to a server-based environment, using MetaFrame XP. One of their concerns is that the two divisions have not standardized their clients. Several different platforms such as Windows, Linux, Mac, and WinCE are currently in use and to replace them would not be cost-effective. How can they overcome this problem? Install and configure the appropriate Citrix client for each platform and operating system. Trade in the machines that do no conform to a standard. Purchase new machines for only the most productive employees and give the older machines to the least productive. Borrow from another area's budget to purchase new machines.

Answers

12.	þ D is by far the best answer. In this scenario, you will have made sure you exceeded the minimum requirements for the operating system and MetaFrame XP, and that you have collected the proper information about the users and applications. ý A covers only the minimum requirements necessary to install the operating system and MetaFrame XP. After the applications have been installed and the users connected, the system would be overtaxed and the users' unhappy with their experience. B was also incorrect, as 256MB of RAM is the minimum requirement for Windows 2000 Server. As a result, the user experience would still be underpowered. Answer C only addresses half the issue. The application load and user load must be figured into the sum of the installed resources.
13.	þ A, B, and C. Microsoft Access can be used in small environments, while Microsoft SQL and Oracle can be used in all environments. ý D is incorrect, because Paradox is not supported.
14.	þ B. ECC RAM or error-correcting code RAM, because it helps cut down on page faults that result in server crashes. ý A, EDO RAM or Extended Data Output Dynamic RAM is fast but does not include the special circuitry that tests for the accuracy of data as it passes in and out of memory. C, VRAM or Video RAM, is a type of RAM used by video adapters to enhance graphic performance. D, Flash RAM is non-volatile memory similar to EPROM. It holds semi-permanent data that can be rewritten.
15.	þ B, C, and D. In B, older DOS programs can consume 25-50 percent more resources than 32-bit programs. If the programs were essential, it would be wise to move them to a second server where the performance would affect the least users. C could also be the problem. Streaming video and real-time stock tickers can consume significant resources. D is also correct. If your environment requires full anti-virus scans, run them at a time when most, or all, users are off the servers. ý A is incorrect because the client machines require very few resources and if the performance was good in the morning, RAM would not cause it to slow.
16.	þ C. Evelyn will also need to select a database, either Access, MS SQL, or Oracle, and decide where to place the data store. She can use Access if there will be 50 or fewer users. If not, she will need to decide upon MS SQL or Oracle. ý A and B are incorrect as the Citrix client requires few resources. Answer D is also incorrect because deciding what applications to run would have been included in her information gathering process.
17.	þ A, B, C, and D. Load balancing increases availability and keeps the servers in a farm from being overburdened. Hot-swappable and redundant parts such as controllers, power supplies, and NICs are important as well. In the event of a failed component, the redundant item will take over. An online spare server is also a good idea. If a server fails, simply move users to the spare.
18.	þ C. To find the minimum amount of resources needed to support a number of users, first find out if they are Power or Typical Users. Each Power User requires 8MB of RAM, while each Typical User requires 4MB of RAM. Then look at the applications that will be installed and make sure you have sufficient resources for those as well. Check the manufacturer's system requirements and, if possible, run Task Manager while an application is running on a PC to see how much memory each consumes. Add the totals together with the operating system and MetaFrame XP requirements and you should have a good base to start with. ý A is incorrect although you would probably end up with enough RAM. B does not address the applications at all, and D will give you plenty of RAM, but doesn't address disk space.
19.	þ C and D. Using the existing PCs with the Citrix client installed can save money. Since all the processing will take place on the server, the clients don't require as many resources. Thin client devices are also much less expensive than PCs because they have no hard drives and don't require as much RAM .ý A could create more problems and restrict productivity, and B might create more expenses and less employee satisfaction.
20.	þ A. The Citrix ICA client is platform-independent and can run on all the mentioned platforms, enabling all clients to connect to the MetaFrame XP server. ý B, C, and D are not cost-effective and may lend to user dissatisfaction.
