10.	Within site A, there are 4 domain controllers: DC1.corp.com, DC2.corp.com, RDDC1.RD.corp .com, and RDDC2.RD.corp.com. DC2.corp.com and RDDC1.RD.corp.com are Global Catalog servers. You are trying to determine which server should hold the infrastructure master role for the corp.com domain. Which server would you place the role on? DC1.corp.com DC2.corp.com RDDC1.RD.corp.com RDDC2.RD.corp.com

Answers

1.	A. A site is a replication boundary for domain controllers in which each domain controller will notify other domain controllers in the same site that there are objects to replicate. This replication occurs between all of the domain controllers without compressing the data. All of the subnets that make up the site should be well connected and have enough available bandwidth to support the uncompressed traffic.
2.	B. Site links are used to create a replication path between domain controllers that exist in two sites. Site links can be created so that they control when the replication can occur and which sites are connected using the site link. They also have a cost value to control how the replication is directed.
3.	A, B. When you create a site link, you can use IP or SMTP to deliver the replicated data.
4.	B. The first site link that is created when Active Directory is installed is the DEFAULTIPSITELINK. You can rename this site link and use it as the site link to link all of the sites if the replication topology is similar among all sites.
5.	D. If no changes are made to a site link, the default cost is set at 100. If all of the sites have the same available bandwidth and replication needs, this cost can be kept. If there are any differences, you will have to determine the replication path you want the replication to take.
6.	B. Site link bridges are automatically enabled in Windows Server 2003 Active Directory. This makes all site links transitive in nature, which allows replication to occur even to sites that are not directly connected to other sites where a domain controller from their domain exists.
7.	C, D. It is recommended that if there are 500 or more users within a site, the domain controller that is authenticating them should have at least dual 899MHz processors.
8.	A. The formula that is used to determine the approximate amount of drive space that the directory database will consume is (number of users / 1000) * .4GB.
9.	B, C, D. Global Catalog servers are used when users authenticate and when users or applications query for Active Directory. If applications that use Global Catalog servers reside in the site, place a Global Catalog server there. If not many users are in the site and not many roaming users authenticate in the site, you could place the Global Catalog server on the other side of the WAN link. If there are several users, many roaming users, or the WAN link is not reliable or is over consumed, plan on placing a Global Catalog in the local site.
10.	A. The infrastructure master should not reside on a Global Catalog server if there are two domains within the forest. The infrastructure master for corp.com can only reside on the DC1.corp.com and DC2.corp.com domain controllers. Because DC2.corp.com is a Global Catalog server, the best domain controller to host the infrastructure master role is DC1.corp.com.
