Overview
Suppose that you are the new administrators for the Contoso Corporation, which is a leading company in
producing smart devices for the home. You need to read the background information for the Contoso
Corporation provided in Appendix, then read the information provided in Task1, Task2, Task3 and Task4,
and then describe your solution for all of them.
For each task you will be creating a proposal that includes the following sections:
➢ Purpose of the Project
➢ Requirements of the Project
➢ The Proposed Solution
When writing the proposal, you must explain the reasoning behind your choices.
This is a group assignment with maximum 4 students in each group and tasks should be distributed among
all group members equally (e.g. one task per student).
Task 1 – Planning an Upgrade and migration to Windows Server 2012 R2
As part of a test system, you administer a test domain consisting of four servers running Windows Server
2008 R2. You have been tasked with upgrading the entire domain and all four servers to Windows Server
2012 R2, including the domain and forest functional levels.
Currently, the systems are used by various groups to test various applications before they are deployed
to production. Therefore, you need to devise an upgrade plan to move the domain to Windows Server
2012 R2.
Task 2 – Designing a fault tolerant DHCP System
The Contoso Corporation has a DHCP cluster running on Windows Server 2008 R2 and the call center has
a Windows Server 2008 R2. You need to create a plan to upgrade the DHCP services to run on Windows
Server 2012 R2. In addition, you need to figure out the best configuration for the DHCP server and scopes
to provide high availability and robust system.
