ASSESSMENT 3

Part A: System Demonstration

Using the system handover document as a basis in assessment 1, demonstrate the setup and configuration of your domain controller to your facilitator and other students. The presentation itself is not assessable, but the quality of your domain controller configuration and your depth of knowledge will contribute to the success of your presentation.

As part of your demonstration identify how you have prepared for work according to site-specific safety requirements and WHS processes and procedures.

The demonstration should not exceed more than 15 minutes. You are required to cover the following topics:

• Windows server 2012 R2 configuration which includes the Active

Directory structure

• User preferences and accessibility
• Main security weaknesses of your domain controller and the corrective action taken to address each issue
• Security features applied to server 2012 R2. You should also log into to a client machine and demonstrate that the security features are applied according to organisation policy
• Testing process you followed
• WHS process and procedures

Ensure that you have an image or complete backup of your system at the end of this task. If this is a problem, please alert your facilitator.

Part B: Short Questions

Complete answers to each of the following questions, adhering to the recommended word limits specified below.
