With the anticipated growth in Billy Bob employees, additional workstations will need to be installed not only on the original floor but on another 2 floors that Billy Bob has now leased. The original workstations, as mentioned, were on the same floor and consisted of workstations (50) used by the Human Resources (5), Engineering & Support (40), and Administration (5) departments accessing a small Active Directory (AD) server (3) system. All of these original workstations and servers were all on the same network. With the addition of 65 workstations; HR (15), E&S (40), and Admin (10), there is now a need to somehow separate/isolate the departments from direct access to each other, you still must use the same Class C network address space, and everyone still needs access to the AD system.

Develop a high-level plan (bullet points) that would accomplish the needed separation/isolation of the updated departments. The details can be worked out later. Be sure to take into account that the existing users can not be down during the day. In your plan, state any assumptions you made.

Be an active participant in the discussion by responding to at least two of your classmates' posts, in a substantive way, before the assignment due date. Spelling and grammar count.
