XYZ is an upstart company located in Calgary. They need a network designed and implemented by a Linux administrator: They have contracted you to set up their infrastructure with basic configurations and

server services using $2$ Red Hat Enterprise Linux Servers. One server must be configured with appropriate files, folders, users, groups and permissions. A second Linux$-$based server will provide DHCP$,$

and DNS services.

The company has three departments: Sales, Human Resources and Engineering, and they have hired six new employees to fill the three newly designed departments. As a Linux administrator, you are responsible to ensure a successful launch of the newly designed departments and the company.
