a. A printer share

  1. What is the purpose of a container in an LDAP-compatible NOS directory?
  1. To organize similar objects for easier management
  1. What is the relationship between threads and multiprocessing?
  2. Processes are made of threads; threads within a process can be handled by different processors to improve server performance.

  1. In a page file on its hard drive
  1. What primary advantage does Windows Server 2008 gain by assigning each operation its own 32- or 64-bit memory area?

a. Multiple applications running simultaneously are isolated and, therefore, are less likely to adversely affect each other.

  1. Suppose you have designed a domain tree for your business, Prestidigit Publications. In that domain tree, you have created two domains: Editorial and Production. You want users from the Production domain to be able to open documents on servers within the Editorial domain. You also want users from the Editorial domain to be able to update documents on servers in the Production domain. At minimum, what kind of trust relationship must exist between the Editorial and Production domains?
  2. Two-way trust
  3. The domains Editorial and Production belong to the same Windows Server 2008 forest. You can, therefore, assume that they share the same:
  4. Schema
  5. What is the common name in the following distinguished name: widgets.com/charleston/marketing/atipton?
  6. atipton
  7. You are the network administrator for an architectural design firm, Keystone Allied, which relies on Windows Server 2008 servers. You have designed the network with three domains in its tree: Administration, Design, and Building. The Administration domain contains three child domains: Executives, Accounting, and Marketing. You have been asked to add a new Canon 7095 printer for Marketing personnel in the Marketing domain. Which of the following could be the printer’s distinguished name?

a. keystoneallied.com/Administration/Marketing/Canon7095

  1. Which character is used to separate directory names on UNIX systems?
  1. Forward slash ( /)
  1. Suppose you want to determine which users are currently logged on to your Ubuntu Linux server. Which of the following commands would allow you to do this?

b. who

  1. Which of the following is an advantage of purchasing a proprietary version of UNIX over an openly distributed version?

b. A proprietary version will be optimized for use on the designated server.

(Answer a, In general, proprietary versions are more stable than openly distributed versions, could arguably also be correct.)

  1. On a Linux or UNIX system, which of the following are stored in a file’s inode? (Choose all that apply.)

a. Access rights

  1. The time and date that the file was last printed
  1. Which file system is native to Linux?
  1. ext3
  1. Another term for the UNIX command interpreter that translates your typed commands into machine instructions is:

a. Shell

  1. Which command would you use to remove a directory on a UNIX server?

a.rmdir

Hands-On Projects

Project 9-1

In this project, students create a user accounts on a Windows Server 2008 computer using the Server Manager GUI.

Project 9-2

In this project, students create a group using the Windows Server 2008 Server Manager application and then add a user to that group.

Steps 1 – 11: Students create the group “Faculty.”

Steps 12 – 15: Students add the user they created in Project 9-1 to the Faculty group.

Steps 16 – 19: Students view the members of the Faculty group and confirm that the user was added to this group.

Project 9-3

In this project, students learn how to create users and groups on a computer running a Linux or UNIX operating system.

Step 1: Students create the group “Faculty.”

Steps 2 – 5: Students create a user and assign the user a password.

Steps 6 – 7: Students are asked to read more about the passwd command in the man pages to learn how to disable and then unlock a user’s account.

Project 9-4

In this project, students log on to the UNIX or Linux server as the user they created in Project 9-3 and then create a directory and assign permissions to that directory.

Steps 1 – 3: Students log on as the user they created in Project 9-3.

Steps 4 – 5: Students create a directory and verify its permissions.

Steps 6 – 7: Students change the ownership for the directory they created.

Steps 9 – 11: Students modify the permissions of the directory they created.

Case Projects

Case Project 9-1

Students should research the differences between Windows Server 2003 and Windows Server 2008 beyond the material provided in this chapter. Easier management and more customizable interfaces (including command-line interfaces for those who prefer them) are just some of the advantages that might convince the AStay IT team to upgrade to this NOS.

Case Project 9-2

Two servers are lacking the necessary processing power, while six servers lack the necessary RAM to run the Standard Edition of Windows Server 2008. Two servers also have barely enough disk space to run the NOS and should therefore probably have more.

Some questions that will help determine whether and by how much the actual hardware should exceed Windows Server 2008’s minimum hardware requirements include:

What type of NOS installation will be performed on each server – a minimum, or one that includes a number of optional services (such as Internet services, remote access services, etc.)?

What type of applications will run on each server, and what are the memory, hard disk, and processor requirements for these applications?

What kind of availability is required (which will indicate how much hardware redundancy – such as dual NICs – is necessary)?

How much traffic will each server need to handle (how many users, what kind of usage, how is the usage distributed over the day and night?)?

How long is the server expected to perform its stated functions? Will it need to perform additional or more strenuous functions in the future? How scalable must the hardware be?

What is the cost of having to take down the server to add more hardware later (as opposed to taking it down once and adding a lot of hardware)?

Case Project 9-3

Students should research and then compare the requirements and capabilities of Ubuntu Linux and Windows Server 2008. For instance, while it’s true that Ubuntu could provide the same basic services as Windows Server 2008, it might require a higher staff commitment to maintaining the NOS, since Ubuntu Linux is open-source, and therefore not supported by a single company. An advantage is that the Linux NOS would require fewer hardware resources, in most cases, to provide the same services that Windows Server 2009 provides.
