70-296 Planning, Implementing, and Maintaining a Microsoft Windows Server 2003 Environment for a W2K MCSE Practice Exam

Demo Question 1.

You work as the systems engineer at EliteCertify.com. You have been given an Active Directory site topology design document. Your job description includes the implementation of network design by means of creating sites, site links, and site link bridges. You have been given instruction to implement the design. EliteCertify.com has two offices: one in Chicago and another in Dallas. The Active Directory implementation consists of a single forest with a single domain and two sites. The two sites are represented by the two offices. The exhibit below illustrates the network: Exhibit: In the Chicago site: 1. Three Windows Server 2003 servers that are configured as domain controllers. 2. Domain controllers are named EliteCertify -DC01, EliteCertify -DC02 and EliteCertify -DC03 respectively. In the Dallas site: 1. Two Windows 2000 Server servers that are configured as domain controllers 2. Domain controllers are named EliteCertify -DC04 and EliteCertify -DC05 respectively. There is a persistent T1 connection between the sites and replication for the site link is set for 3

A. M. to 6 M. (EST) the replication frequency is set to 90 minutes. You have been given instruction to control which domain controllers are to manage site-to-site replication. To this end you want to implement preferred bridgehead servers. Now you need to decide on the amount of preferred bridgehead server in the Dallas site. What should you do? You should implement one preferred bridgehead server in the Dallas site.
B. You should implement two preferred bridgehead servers in the Dallas site.
C. You should implement three preferred bridgehead servers in the Dallas site.
D. You should implement four preferred bridgehead servers in the Dallas site.
E. You should implement five preferred bridgehead servers in the Dallas site.


Display Answer

Answer: A

Explanation: A bridgehead server is a domain controller that sends and receives replicated data at each site. The bridgehead server from the originating site collects all replication changes and then sends them to the receiving site's bridgehead server which in turn replicates the changes to all domain controllers in the site. Each domain must have a bridgehead server. Since there is a single domain in Dallas site, you must have a single bridgehead server for the site. Incorrect answers: A - E. It is considered good practice to have more than one preferred bridgehead server in a site. However if you are to control which domain controllers are to manage site-to-site replication, it must be one preferred bridgehead server and not more. If you specify a custom list of bridgehead servers, Active Directory will first try to use the first server on the list to send replication data to the other site. If it cannot locate the first server in the list, it will try the next server in the list until it finds an available server to perform replication.
