INTRODUCTION
GT7 network design, configuration and testing is focused on creating and validating an efficient solution
and implementing services for a modern network. The case study provided necessitates a thorough
understanding of the requirements for the client. The overall aim is to transcend the network to more
secure infrastructure, integrate up-to-date technologies and support any perceived future growth within
the next five years.
Logical network design is the foremost task to be completed as every other process relies on the
outcomes of an accurate IP addressing. Logical network addressing creates an IP addressing scheme
which guarantees the connectivity of all devices on the network. The configuration of network services
is the next phase and includes services as domain controller, DHCP, DNS and a web server for HTTP
traffic. To guarantee availability of network services and eliminate downtime, some services are
configured to for redundancy. The configuration and verification of these services is aided by the use of
virtualization. It facilitates the creation of operating systems as software files by allocating physical
computing resources to a virtual hardware or virtual machine. The entire procedure is documents in
each section and closes with a section describing the scope of work achieved and the results obtained.
LOGICAL NETWORK DESIGN
In a network, every host requires an IP address assigned statically or dynamically before it can
communicate with devices on the network. The client description of the host requirements for the HQ
office and the Brisbane office captured in the request. The devices on the new network are PC’s, IP
phones and servers. The specified address space for the HQ office is 172.1x.yx.0/24 and 192.1y.yx.0/24.
Where x and y are the last two digits of my student ID. Multiplying the number of employees at each
office location by two as each own two devices and adding the total servers gives 216 host IP addresses
for the HQ and 129 host IP addresses. The table depicting the number of users is thus.

NETWORK IMPLEMENTATION PLATFORM
The daunting task of selecting the perfect tool for this implementation and deciding which platform
offered features match the requirements. The choice of virtualization reflects an economical software
solution for implementing virtual machine. The specific product is oracle virtualbox, a type-2 hypervisor
that is open-source and supports enterprise level functionality. The software runs on windows, UNIX,
and supports different operating systems. Two servers for each location and a windows PC will be
configured to test the solution of each task. Similar to every virtualization platform, virtualbox abstracts
physical resources and allocates them to virtual machines. Furthermore, network hardware can be
virtualized and connected to the virtual machine thus providing same level of access to physical
hardware.
Next, from the VM manager console, we create new virtual machine for each network host adding
hardware and configuring the HDD size and RAM for operating system. The procedure for operating
system installation takes substantial time as it follows the same stages for installation on physical
hardware. Prior to installing any operating system, the image files are downloaded and stored locally for
easy access to the virtualbox manager.

An internal local area network was created on each virtual machine by assigning the first adapter to the
internal network type and selecting an adapter type in the advanced tab. The network would enable
each virtual machine to send packets between the interfaces. This internal network replaces a physical
switch. The networking setting in VirtualBox contains a rich set of feature that can be used for other
purposes.

INSTALLING A DOMAIN CONTROLLER
Installing the domain controller is a two-step procedure. Prior to any installation, the server will be
assigned an IP address from the list of addresses proposed by the logical network design. First we install
the Active Directory Domain Services role, and with it a DNS Server role is automatically installed when
the procedure concludes. The next step is to promote the server to become a domain controller. To
install Active Directory Domain Services, access Server Manager, and in the Dashboard pane, select Add
roles and features link. Select installation type page, verify that Role-based installation is selected and
then select next. On the Select server roles page, select the checkbox for Active Directory Domain.
Follow through the procedure and selecting next at each screen, confirming the installation in the final
step. Wait for it to complete.

To promote the server to a domain controller in Server Manager, the Notification Area flags a warning
that requires attention. Click the icon and select the Promote this server to a domain controller link.
Create a new forest for maradapa.com, configure the DNS info, and validate the data at each step. The
server reboots after installing Active Directory Domain Services on a server and the default domain
administrator account is used to login.

In Server Manager, select Tools and navigate to Active Directory Users and Computers. Active Directory
Users and Computers is utilized to create, and manage, Active Directory objects for a domain. In the left
pane select the domain and right-click to create an organization unit that will store the users and
groups. Clicking on the right pane a menu reveal several options, scroll to new and use it to create new
users and groups. When the process completes rich-clicking on a user account and selecting properties
shows numerous options. Select the “member of” to add the user account, search the list and add the
account, the user is now a member of that group. The procedure is repeated for other users.
