Assignment 3

  

For the final assignment, summarize the site requirements and/or any challenges (changes to the topology as you detailed in Assignments 1 and 2) you are attempting to overcome. You should also provide an updated overall site topology based on your design.

This solution should be comprehensive, and the approach should be justified. Configurations of technologies should be written out to help guide the systems administrators with implementation. In some cases, you may find it necessary to implement additional cabling, which can be done by adding to the supplied topology. Any adjustments to the sites’ topology should be documented and supplied with your submission.

Analyze and visual

Kirk (2019) notes the importance of formulating your brief.  What does he mean by this?  Please expand this thought by noting how you would create a vision for your work.  Note any real-world examples to expand upon this thought.

Installing Windows and Linux

Part 1

Using VirtualBox create a new Virtual Machine with 2 GB to 4 GB of memory and a 120 GB hard drive (thin provisioned). Using the  Windows Install Media, install Microsoft Windows 10 and create a “local” non-online user account. This is harder than it looks, so you will need to research how on the Internet. Open the text editor in Microsoft Windows (Notepad). Enter the following text: “Hello in Microsoft Windows from FIRSTNAME LASTNAME”, replacing first name and last name with your name. Create a screenshot of the virtual machine using VirtualBox and upload it to this assignment.

Part 2

Using VirtualBox create a new Virtual Machine with 2 GB to 4 GB of memory and a 120 GB hard drive (thin provisioned). Using the Ubuntu Install Media, install Ubuntu LTS with a personal user account. You may need to research how to accomplish this by searching the internet. Open the text editor in Ubuntu (Notepad/gedit). Enter the following text: “Hello in Ubuntu from FIRSTNAME LASTNAME”, replacing first name and last name with your name. Create a screenshot of the virtual machine using VirtualBox and upload it to this assignment.
