Question: 1 You are a network administrator for Company. The network consists of a single Active Directory forest that contains three domains. The functional level of the forest and of all three domains is Windows Server 2003. Company has a main office and 30 branch offices. Each branch office is connected to the main office by a 56-Kbps WAN connection. You configure the main office and each branch office as a separate Active Directory site. You deploy a Windows Server 2003 domain controller at the main office and at each branch office. Each domain controller is configured as a DNS server. You can log on to the network from client computers in the branch offices at any time. However, users in the branch offices report that they cannot log on to the network during peak hours. You need to allow users to log on to the network from branch office computers. You do not want to affect the performance of the branch office domain controllers. You need to minimize Active Directory replication traffic across the WAN connections. What should you do? A. Use Active Directory Sites and Services to enable universal group membership caching for each branch office site. B. Use the DNS console to configure the branch office DNS servers to forward requests to a DNS server in the main office. C. Use Active Directory Sites and Services to configure each branch office domain controller as a global catalog server. D. Use the DNS console to configure the branch office DNS servers to use an Active Directory-integrated zone.

Answer: A Explanation: When a user logs on to the network, the global catalog provides universal group membership information for the account to the domain controller processing the user logon information. If a global catalog is not available when a user initiates a network logon process, the user is able to log on only to the local computer unless the site has been specifically configured to cache universal group membership lookups when processing user logon attempts. In this scenario the domain controller must contact the global catalog server across a WAN link that is saturated. Enabling universal group membership caching will overcome this problem. Incorrect Answers: B: When users log on, the requests are sent to the global catalog not the DNS server. C: Configure each branch office domain controller as a global catalog server would result in increased replication traffic. We want to avoid this. D: An Active Directory-integrated zone is a DNS zone that is part of Active Directory and is part of Active Directory replication. Making the DNS zone a part of Active Directory will not overcome logon latency and will lead to an increase in replication traffic.

Question: 2 You are the network administrator for Company.com. The network consists of a single Active Directory domain named Company.com. The functional level of the domain is Windows Server 2003. You configure two Active Directory sites named Company1 and Company2. Company1 contains all of the operations masters and two global catalog servers. Company2 contains a domain controller named Server1. You create a site link named SiteLink1 that includes Company1 and Company2. You need to provide global catalog services locally in Company2. Which Active Directory component should you configure? To answer, select the appropriate component in the work area.

Answer: Select “NTDS Settings� under SERVER1. Explanation: The global catalog service is added or removed in the NTDS Settings Properties dialog box of the Active Directory Sites and Services console.

Question: 3 You are a network administrator for Company. The network consists of two Active Directory domains. All servers run Windows Server 2003. Company has offices in several cities as shown in the exhibit.

Each office is configured as an Active Directory site. There are global catalog servers in the Toronto and Paris sites. You enable universal group membership caching for all other sites. Users in your company use an application that is integrated with Active Directory. The application reads data from the global catalog. Users report that during periods of peak activity, the application responds slowly. You need to improve the response time of the application. What should you do? A. Disable universal group membership caching in the Chicago, New York, Bonn, and Rome sites. B. Decrease the replication interval on the site links that connect the Chicago and New York sites to the Toronto sites, and on the site links that connect the Bonn and Rome sites to the Paris site. C. Configure global catalog servers in the Chicago, New York, Bonn, and Rome sites. D. Perform an offline defragmentation of the Active Directory database on the domain controllers in the Toronto and Paris sites.

Answer: C Explanation: The application reads data from the global catalog, however, there are Global Catalog servers only in Toronto and Paris. Therefore, global catalog information must be accessed across the WAN links, which is where the problem occurs. We need to add Global Catalog servers in the Chicago, New York, Bonn, and Rome sites. Incorrect Answers: A: Universal group membership caching is used for logon purposes. It is thus irrelevant to this scenario. B: Decreasing the replication interval will not improve response times. The Chicago, New York, Bonn, and Rome sites must still access the global catalog information across the WAN links. D: Deframenting the Active Directory database will not improve response times significantly; the Chicago, New York, Bonn, and Rome sites must still access the global catalog information across the WAN links.

Question: 4 You are the network administrator for Company.com. Company has offices in Chicago, New York and Toronto. Each office employs 500 people. The network consists of a single Active Directory forest with one domain in each office. Each domain contains two domain controllers named Company1 and Company2. All domain controllers run Windows Server 2003. Each office is configured as an Active Directory site. The domain structure is shown in the exhibit.

New York Toronto The Windows Server 2003 computer named Company1.Company.com holds all operations master roles for its domain, and it holds both forest-level operations master roles. The Windows Server 2003 computer

named Company1.sales.Company.com and Company1.prod.Company.com hold all operations master roles for their respective domains. WAN connectivity between the offices is unreliable. You need to plan the placement of global catalog servers for the network. You need to ensure that each user can log on in the event of the failure of a single domain controller and WAN connection. You need to ensure that the consistency of universal group membership information remains intact. Which two actions should you take? (Each correct answer presents part of the solution. Choose two) A. Configure both domain controllers in Company.com as global catalog servers. B. Configure only Company1 in each domain as a global catalog server. C. Configure only Company2 in each domain as a global catalog server. D. Enable universal group membership caching for each site. E. Enable universal group membership caching for the Chicago office. F. Enable universal group membership caching for the Toronto office and the New York office.

Answer: A,F Explanation: We could have global catalog server s in each site. This would ensure that users can log on in the event of a WAN connection failure. However, we also need to ensure the consistency of universal group membership information. Therefore, placing global catalog servers in the remote sites are not an option. Instead, we need to enable universal group membership caching for both remote sites. For redundancy purposes, the main site must have more than one global catalog. Incorrect Answers: B, C: For redundancy purposes, the main site must have more than one global catalog. E: We need to enable universal group membership caching for both remote sites.

Question: 5 You are a network administrator for Company.com. The network consists of two Active Directory domains. All servers run Windows Server 2003. Company has offices in New York and Rome. The two offices are connected by a 128-Kbps WAN connection. Each office is configured as a single domain. Each office is also configured as an Active Directory site. Company stores printer location information in Active Directory. Users frequently perform searches of Active Directory to find information on printers by selecting the Entire Directory option. Users in the New York Office report that response time is unacceptably slow when searching for printers. You need to improve the response time for users in the New York office. What should you do? A. Place a domain controller for the Rome domain in the New York office. B. Place a domain controller for the New York domain in the Rome office. C. Enable universal group membership caching in the New York office. D. Configure a global catalog server in the New York office.

Answer: D Explanation: The global catalog is the central repository of information about Active Directory objects in a tree or forest. The domain controller that holds a copy of the global catalog is called a global catalog server. The global catalog enables a user to log on to a network by providing universal group membership information to a domain controller when a logon process is initiated, and enables finding directory information regardless of which domain in the forest actually contains the data. Incorrect Answers: A: This would work but it is unnecessary. Replicating the entire Active Directory from the Rome office to the New York office over the slow WAN link is a waste of resources. A global catalog server in the New York office would suffice. B: This won’t solve the problem at all. C: Universal Group caching (as its name implies) caches information about universal groups. This scenario involves searching for printers which is nothing to do with universal groups.

Question: 6 You are the network administrator for Company.com. The network consists of a single Active Directory forest that contains a forest root domain named Company.com and a child domain named child2.Company.com The functional level of the forest is Windows Server 2003. The company uses universal groups to prevent temporary employees from accessing confidential information on computers in the forest. The child1.Company.com domain contains a Windows 2000 Server computer named Company1. Company1 runs an application that makes frequent LDAP queries to the global catalog. Company1 is located on a subnet associated with an Active Directory site named Site2 that has no global catalog servers. Site2 is connected to another site by a WAN connection. You need to enable the application on Company1 to run at high performance levels and to continue operating if a WAN connection fails. You also need to minimize traffic over the WAN connection. What should you do? A. Enable universal group membership caching in Site2. B. Configure at least one global catalog server in Site2. C. Add the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\IgnoreGCF-ailures key to the registry on all domain controllers in Site2. D. Remove Server1 from the child1.Company.com domain and add it to a workgroup.

Answer: B Explanation: The application needs to read data from the global catalog. This information is stored on the global catalog servers in the other site. This means that the application needs to contact the global catalog servers over a WAN link. We can improve performance by configuring a global catalog server in site2. This will enable the application to contact a global catalog server over fast LAN connections. It will also enable the application to run if the WAN link fails. Incorrect Answers: A: Universal group caching likely has no effect on the application. Universal group information is just a small part of the information stored in the global catalog. The application would still need to contact a global catalog server. C: This setting allows users to log on to a domain if the domain controller is unable to contact a global catalog server. It will have no effect on the application. D: The application won’t be able to query the global catalog if the computer isn’t a member of the domain.
