Active Directory Multi-Master Design

The Acme Widget Technical School has four campuses: one main campus and three branch campuses. All campuses currently have a child domain off the main domain, located at the main campus in Wiley, Minnesota. The main campus has approximately 125 employees and 2,000 students, while each branch campus has approximately 50 to 75 employees and 1,200 students. The main campus is called Wiley, the other campuses are Ethelbert, Freling, and Jones.

Using the information from this scenario, answer the following questions:

1. How many and what type of domain controllers do you recommend for each campus? How would you justify this recommendation?
2. How many global catalog servers do you recommend for the campus? How would you implement and configure these global catalog servers?
3. Explain the steps for determining the placement of the FSMO roles for the Acme Widget Technical School. How are these roles determined, implemented, maintained, and monitored?
4. As a System administrator, detail some best practices as well as errors that can occur from improper setup and implementation of global catalogs or FSMO roles.
