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

Demo Question 5.

You work as the systems engineer at EliteCertify.com. You have been given an Active Directory site topology design. Your job description includes the implementation of network design by means of creating sites, site links, and site link bridges. The design consists of a single Active Directory forest that contains three domains. These domains are named EliteCertify -north.com, EliteCertify -south.com, and EliteCertify -west.com respectively. You implement three sites named EliteCertify A, EliteCertify B, and EliteCertify C respectively. Each of the three sites hosts a single domain and domain controller that runs Windows Server 2003. You then configure the following site links: 1. Site Link AB between EliteCertify A and EliteCertify B 2. Site Link BC between EliteCertify B and EliteCertify C Both site links have persistent T1 connections. The following exhibit illustrates the network design: Exhibit: The IP network is not fully routed and the firewalls at each site are configured to only allow replication between domain controllers on specific subnets. The EliteCertify A site domain controller named EliteCertify -DC01 serves as a global catalog server. EliteCertify -DC01 requires data from the domain controller in the EliteCertify C site. You want to optimize the communication between site EliteCertify A and site EliteCertify C. What should you do?

A. Disable automatic site link bridging and then implement a site link bridge between EliteCertify A and EliteCertify
B. Enable automatic site link bridging and then implement a site link bridge between EliteCertify A and EliteCertify
C. Disable automatic site link bridging and then implement a site link bridge between EliteCertify A and EliteCertify
D. Enable automatic site link bridging and then implement a site link bridge between EliteCertify B and EliteCertify C.


Display Answer

Answer: C

Explanation: You want to disable automatic site link bridging so that you will be able to create a custom site link bridge that will correspond to the actual routing behavior of the network as described in the question. It is mentioned in the question that this is not a fully routed IP network, thus you will have to create a site link bridge between EliteCertify A and EliteCertify C. Incorrect answers: A. Disabling automatic site link bridging is correct but then you should also create a custom site link bridge between EliteCertify A and EliteCertify C instead of with EliteCertify B involved since there is already a site link between these two sites. B. Enabling automatic site link bridging might result in site link bridges that are created automatically that may not correspond to the natural most efficient method of transport between sites. D. Enabling automatic site link bridging might result in site link bridges that are created automatically that may not correspond to the natural most efficient method of transport between sites. Furthermore a link between these two sites would be incorrect.
