As a Network Administrator for NTCOM, you have been tasked with designing an Active Directory based network which uses Active Directory Integrated DNS. The company has 5 separate departments Development, Testing, HR, Management and Finance. Each of these departments have its own logical boundaries and an IT Admin from each department is given some responsibilities of managing day to day IT issues specific to that department. HR and Finance have around 20 Workstations each with 20 users. The company also has 3 Printer and 3 File Servers which are shared only by Finance and Management. Development and Testing divisions have its own Printer on top of 16 workstations for 16 users. However, any of the 3 printers can be shared between all the departments in case any one of the printer is down. NAT functionality should also be included.

Describe in detail how the above scenario can best be implemented and provide logical explanation in each of the steps for your chosen design. You can add diagrams (clear and precise) to convey your ideas
