Chapter Review

  • Article

To further practice and reinforce the skills you learned in this chapter, you can perform the following tasks:

  • Review the chapter summary.
  • Review the list of key terms introduced in this chapter.
  • Complete the case scenarios. These scenarios set up real-world situations involving the topics of this chapter and ask you to create a solution.
  • Complete the suggested practices.
  • Take a practice test.

Chapter Summary

  • The Next Generation TCP/IP stack of Windows Vista supports both IPv4 and IPv6.
  • Computers that are using IPv4 can be configured to use a DHCP-assigned address. Users can also manually set the IP address, subnet mask, default gateway, and DNS server address(es) for the computer.
  • Windows Vista includes built-in tools for connecting to wireless networks and managing wireless network functionality.
  • Windows Vista supports the Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) wireless security standards.

Key Terms

Do you know what these key terms mean? You can check your answers by looking up the terms in the glossary at the end of the book.

  • ad hoc wireless network
  • default gateway
  • Domain Name System (DNS)
  • Dynamic Host Configuration Protocol (DHCP)
  • Internet Protocol v4 (IPv4)
  • Internet Protocol v6 (IPv6)
  • IP address
  • local area network (LAN)
  • Service Set Identifier (SSID)
  • subnet mask
  • Wi-Fi Protected Access (WPA)
  • Wired Equivalent Privacy (WEP)

Case Scenarios

In the following case scenarios, you apply what you’ve learned about configuring Windows Vista networking. You can find answers to these questions in the “Answers” section at the end of this book.

Case Scenario 1: Adding a New Computer to a Network

You are a Consumer Support Technician assisting a customer with configuring a new wired network connection in his home. In the past, you assisted him with setting up a home network connection. The network currently does not have any method of automatically assigning network addresses. The IPv4 information you used on the original computer includes the following:

  • IPv4 Address: 10.10.0.120
  • Subnet Mask: 255.255.255.0
  • Default Gateway: 10.10.0.1
  • DNS Server Address (Primary): 10.10.0.1

The other computer is working properly and can access the Internet. He would like the new computer to be able to access the Internet and to be able to communicate with the other computer. There are no other computers on the network.

  1. What IP address should you assign for the new computer?
  2. What value should you use for the subnet mask of the new computer?
  3. How can you manually configure the network settings for the TCP/IPv4 protocol on the new computer?
  4. How can you simplify the process of managing network address information for future computers that are added to the network?

Case Scenario 2: Managing Wireless Network Connections

You are a Consumer Support Technician assisting a customer with configuring a wireless connection for use in multiple scenarios. The customer states that she frequently travels between multiple locations and wants to use the features of Windows Vista to connect to wireless networks quickly and easily when they are available. Examples of typical locations include the customer’s home, her local office, coffee shops, airports, and hotel rooms. In some locations, such as her local office, multiple wireless network connections are available, but the customer would like to connect automatically to only one of these. Occasionally, she will share her lap-top computer with a co-worker who already has an account on the computer.

  1. For security reasons, the customer would like to be prompted for a key or passphrase whenever she connects to a new wireless network. How can you configure this?
  2. How can you specify an order of preference for wireless network connections that are available at the customer’s local office?
  3. How can the customer configure some connections to connect automatically for only her user account?

Suggested Practices

To help you successfully master the exam objectives presented in this chapter, complete the following tasks.

Managing Network Connections in Windows Vista

The following practices help you become familiar with various methods of working with wired and wireless network connections in Windows Vista.

  • Practice 1: Configure Network Connections Choose several different computers running Windows Vista and examine their network configurations. If possible, attempt to connect new computers to a test wired or wireless network and keep track of the settings that you have decided to use. Use the Network Map feature of the Network And Sharing Center to gain an overview of all of the available computers in the environment.
  • Practice 2: Troubleshoot Network Problems Choose a computer running Windows Vista that has either a wired or wireless network connection. Manually make various changes to TCP/IPv4 settings, such as the IP address, subnet mask, default gateway, and DNS servers. Choose values that might not be compatible with the current network. Then, use the Diagnose and Repair options to try to troubleshoot the problems automatically. Additionally, use command-line tools such as IPCONFIG, PING, and NETSH to help determine the source of problems and to correct them.

Take a Practice Test

The practice tests on this book’s companion CD offer many options. For example, you can test yourself on just one exam objective, or you can test yourself on all of the 70-623 certification exam content. You can set up the test so that it closely simulates the experience of taking a certification exam, or you can set it up in study mode so that you can look at the correct answers and explanations after you answer each question.
