In the following case scenario you will apply what you ve learned in this chapter. You can find answers to these questions in the Answers section at the end of this book.

You work as a domain administrator for Fabrikam, Inc. Your responsibilities include managing the Active Directory and network infrastructure, including DNS. The DNS servers for the Fabrikam.com domain are all installed on domain controllers. 1. Recently you have noticed that some records in the Fabrikam.com zone refer to computers that were removed from the network several months ago. What is the best way to remove these stale records 2. What is the best way to prevent such data from accumulating in the future 3. You want to allow records to remain in the zone for 21 days without being scavenged. However, you want to prevent timestamps from being refreshed for the first seven days after each record is first created in the zone. How should you configure the No-Refresh and the Refresh intervals

You are a network administrator for City Power and Light, whose network is composed of a single Active Directory domain, Cpandl.com. The Cpandl.com zone is stored in Active Directory. At the company headquarters the Cpandl.com domain controllers host the DNS zones for the domain. The Cpandl.com network also includes several branch offices. 1. The Rochester office does not include a DNS server. You want to improve name resolution of computer names in the Cpandl.com domain, but you don t want to host a domain controller at the Rochester site. Minimizing zone transfer traffic is not a priority. What should you do 2. You want zone transfers to the Rochester office to occur whenever a change occurs in the zone data. How can you enable this functionality

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

The following practices will deepen your understanding of DNS replication within multidomain forests. They both require three computers, but you can still perform these practices easily by using virtual machine software such as Virtual PC.

Practice 1 Using virtual machines, create an Active Directory forest with two domain controllers in a domain named Contoso.com and one domain controller in a child domain called East.contoso.com. Choose the option to store both DNS zones in all DNS servers in the forest. View the zone data and then add a record manually to each zone. Force replication by using Active Directory Sites and Services. Practice 2 Using the same three-computer network, create a custom application directory partition on the domain controller in the East.contoso.com domain. Configure the zone to store its data in the newly created partition. Enlist only one of the domain controllers in the Contoso.com domain in the partition. Reboot each computer and then verify that the zone data is stored on only two of the three servers.

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 the 70-642 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.

For details about all the practice test options available, see the How to Use the Practice Tests section in this book s Introduction
