1. You are designing a site plan for a company that has full corporate offices in Atlanta, Chicago, and Los Angeles. Each location is connected to the other two locations via a 512 Kbps connection. How many sites should you define

You should define three sites, one for each location. To be part of the same site, a 10 Mbps or better connection should connect subnets.

Sites are used to control network traffic generated by workstation logon, Active Directory repli cation, DFS, and FRS.

You should create a site for each LAN or set of LANs connected by a high-speed backbone. You should create a site for each location at which you plan to place a domain controller. You should also create a site for each location running a server that hosts a site-aware application or where there is high latency caused by geographic distance or the type of WAN link (e.g., a sat ellite link).

1. How many domain controllers would you place in each site Why Use the table below to complete your design.

Domain Number of Domain Controllers in Each Site Paris Nwtraders.local AsiaPacific.nwtraders.local NAeast.nwtraders.local NAwest.nwtraders.local Corp.nwtraders.local RDNwtraders.local Glasgow.RDNwtraders.local

This is just one possible answer. Paris will host one domain controller for every other domain to enable easy logon for users from other locations when they are in Paris. It will also host three domain controllers for the corp.nwtraders.local domain, two for local authentication, and a third one for managing replica tion to remote offices. For redundancy purposes, it will also host two domain controllers for the forest root domain (nwtraders.local).

Glasgow will host two domain controllers for the RDNwtraders.local forest root domain and two for the Glasgow.RDNwtraders.local domain. Two domain controllers for each domain are required to support fault tolerance for Active Directory. Glasgow will also host one domain controller for the corp.nwtraders.local domain so that traveling users from headquarters can log on Each of the remaining sites will host two domain controllers for the local regional domain for fault tolerance, one domain controller for the forest root domain, and one domain controller for the corp.nwtraders.local domain to enable traveling users from headquarters to log on without using the WAN link.

2. In which sites will you place global catalog servers In which sites will you enable universal group membership caching Use the following table to complete your design.

Number of Global Catalog Servers for Nwtraders.local Forest 2 1 1 1 1 Number of Global Catalog Servers for RDNwtraders.local Forest 1 1 0 0 0 Enable Universal Group Membership Caching for Site (Yes/No) No No No No No

To support local logon, each site except for Paris will host one copy of the global catalog for nwtraders.local forest. Paris will have two copies of the global catalog to support both the large number of users in the location and the volume of Active Directory searches that are performed by the local IT staff.

1. What are the reasons for placing domain controllers into a site What are reasons you might not be able to place a domain controller into a site

If the site contains many users, a local domain controller cuts down on authentication traffic to other sites. If the WAN link between sites goes down, having a local domain controller ensures continued authentication. If there are site-aware applications in a site, having a local domain controller cuts down on WAN traffic. You should not place a domain controller in a site if no one in that location can manage the domain controller (and you cannot set up remote access) or if you cannot guarantee the phys ical security of the domain controller.

2. You are determining the number of domain controllers to place in a site. There are 15,000 users in the site, and there are eight replication connections to the site. How many domain controllers should you place

You should place at least three domain controllers in the site. For between 1,000 and 10,000 users, two domain controllers are recommended. You should add another domain controller for every 5,000 users above 10,000.
