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

Demo Question 3.

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 EliteCertify.com design consists of four sites named EliteCertify A, EliteCertify B, EliteCertify C, and EliteCertify D respectively. These four sites are connected via Wide Area Network (WAN) links as the following exhibit illustrates: Exhibit: The IP network is fully routed, but the Wide Area Network (WAN) links between EliteCertify A and EliteCertify B and between EliteCertify C and EliteCertify D are unacceptably slow. Due to this slow WAN link you want to prevent EliteCertify B from replicating directly with EliteCertify D. You thus delete the default site link and disable the default bridging of all the site links. However, you should take care and ensure that all the other sites will still be able to directly replicate with each other. What should you do?

A. Create a site link that includes EliteCertify A, EliteCertify B and EliteCertify C. Create a site link that includes EliteCertify A, EliteCertify C and EliteCertify D.
B. Create a site link that includes EliteCertify A, EliteCertify B, EliteCertify C and EliteCertify D.
C. Create three site links between: EliteCertify A and EliteCertify B; EliteCertify A and EliteCertify C; EliteCertify C and EliteCertify
D. Create a site link bridge that includes EliteCertify A, EliteCertify B, and EliteCertify C Create a site link bridge that includes EliteCertify A, EliteCertify C and EliteCertify
E. Create three site link bridges between: EliteCertify A and EliteCertify B; EliteCertify A and EliteCertify C; EliteCertify C and EliteCertify D.


Display Answer

Answer: A

Explanation: Site links are logical objects that represent the sites' physical connectivity with each other. The Knowledge Consistency Checker (KCC. assumes that all domain controllers in the sites that belong to the same link can communicate directly with each other. If the actual WAN topology does not support direct connectivity among all domain controllers, then you can delete the default site links and create the appropriate site links for you network. You can bridge those site links that include at least one common site. In this scenario you should create two site links: a site link that includes EliteCertify A, EliteCertify B and EliteCertify C; and a site link that includes EliteCertify A, EliteCertify C and EliteCertify D. Incorrect answer: B. This option is not correct since you need to create site links and not one that includes all four sites. C. This is incorrect since this option's site links suggestion will allow EliteCertify B to replicate directly with EliteCertify D. D. Bridges can only include site links, they cannot include sites. Thus this option is incorrect. E. Site link bridges can only include site links and not sites.
