NETWORK TECHNOLOGY AND MANAGEMENT
Introduction
Quality network design together with powerful network devices can greatly benefit companies,
organizations, and business by enhancing productivity and increasing the overall performance of the
company (Bach, 2013). The choice of the kind of network topology to be used also affects network
performance and reliability and thus the need to implement an appropriate topology to ensure high
availability and reliability (Zhang and Shin, 2013, p. 431). Color Ability Corporation (CAC) is an advertising
and marketing company that has experience growth and now their current operating space, Level 10
and 11 of X Tower in Brisbane CBD, is no longer enough. Because of this, CAC has purchased a four-story
building in one of the Brisbane Suburbs and plans to move there in the next three months. This report
highlights the various activities that has to be carried out in regards to network design and
implementation in the new building before they move. Of focus is the recommendation of various
computer systems to be used by different employees in different departments, printers to be shared by
employees and managers, network devices such as router, switch, and access points, internet, service
provider, IP addressing, and the security benefits of using both public and private IP.

It supports double-sided printing and high quality and professional quality print. This printer will
serve CAC managers well offering the best printing services.
Activity 3
Network performance greatly depends on the type and quality of networking devices. Good
network infrastructure will increase the overall performance and productivity of the business (Levin,
2017). The following devices are recommended to be used by CAC:
Router
Cisco 4000 series router is recommended to be used for the CAC network. This is an intelligent
router that is able to detect and filter any suspicious traffic and block them from getting into the internal
network. This model supports virtualization to ensure that the network resources are available all the
time at any place. Secondly, it has the ability to automate the network by using Cisco DNA center to
enforce business policies to monitor and configure the network thus increasing work performance
(Cisco, 2018).
Figure 3: Cisco 4000 Series Integrated Services Routers
Some of the network services that Cisco 4000 series offers include unified communication,
intelligent caching, optimization of applications and WAN connection, and software-defined WAN. It has
also been integrated with security features to protect the connections across the sites (Hohlfeld, Zinner,
Benson and Hausheer, 2015, p. 4).
Switches
Cisco Meraki MS225-48 is the recommended switch to be used while setting up the network. It
is a 48-port switch which has auto-MDIX crossover and supports 10/100/1000BASE T ethernet
connection (Athow, 2018).
Figure 4: Cisco Meraki MS225-48

NETWORK TECHNOLOGY AND MANAGEMENT
It supports power over ethernet in all the ports and applies 802.3af security standards. it
supports remote management through Meraki dashboard which is user friendly and easy to use
(Woodward and Feuer, 2013). Other features include client, DHCP, and hostname fingerprinting, remote
diagnostics, notification alerts via email and SMS, failure detection, flexible stacking, ethernet switching
capabilities, prioritization of quality of service, 2-factor authentication integration, enforcement of
corporate wide password policy, role-based access control, STP enhancements, port security, and DHCP
detection, snooping, and blocking (Cisco, 2018). This feature ensures high performance network through
flow control support and switching capacity.
Wireless Access Point
Wireless access points facilitate wireless connection for employee devices such as mobile
phones, laptops, and tablets (Wolf, 2010, p. 7). The best, affordable, and powerful access point that will
be able to meet the set requirement is Cisco Business 100 series.
Figure 5: Cisco Small Business 100 Series Wireless Access Points
Installation and configuration of this WAP is easy because of the integrated setup wizard and
intuitive web-based setup (Hoque and Gupta, 2012, p. 14). It further offers high-speed wireless
connection with 802.11ac/n security standards which improves productivity and range. Also, it has
advanced security features such as roque access point detection, WPA2, Radius secure authorization
802.1X. furthermore, it supports easy scalability and expandability and consumes less energy (Cisco,
2018).
Activity 4
Internet connection is very important to any business or company. The choice of the internet
service provider will determine the overall network performance because of the internet speed
(Karyakina and Melnikov, 2017, p. 253). The ISP should be able to assure high availability will minimal or
no downtime. The table below shows a comparison of two local ISP that Color Ability Corporation can
get internet connection from:

Table 6: Local Internet Service Providers
Despite the high charges demanded by Foxtel, Vodafone still offer better and more reliable
internet services. CAC will be able to enjoy premium internet speed at lower cost. Vodafone also offer
24/7 support to their customers. Moreover, Vodafone has a good reputation as compared to Foxtel
(Weng, Yang and Lai, 2014, p. 679). As such, Color Ability Corporation should acquire its internet from
Vodafone.

CAC employee expect some services to be offered internally. The table below describes some of
the internal services that should be provided and supported by the network:
Service Device Justification
Application
management
Application
Server
To offer centralized management and administration of application.
This ensures that all the applications are available to all users at any
time (Gentile, Griffith and Souryal, 2012, p. 50). Additionally, it makes it
easier to monitor how different users use the application and further
makes it easy to update the applications.
Printing
Services
Print server Manages all the print jobs sent to the printer and prioritizes printing
jobs based on priority.
IP allocation DHCP Server To allocate the users with IP addresses dynamically to enable them
access the internet and other network resources.
Email Services Mail server CAC being a marketing and advertising company, it is expected that a
lot of emails will be sent and received. As such, there is need to have a
server to manage email messages sent and receive and ensure backup
of such communications for future reference (Wang, 2014, p. 175).
File Storage File Server This allows centralized storage of all the shared files and ensures that
all the employees have access to complete and up-to-date files at all
time (Gagliardi and Alhabib, 2015). This enable the employees to use
similar information to perform their tasks.

Table 10: IP Addressing Table
Activity 8
Using Private IP and Public IP to Enhance Network Security
Internet service providers are often faced with shortages in public IP address. As such it will be
difficult to cover the security needs of the Colour ability Corporation. Therefore, due to this limitation
CAC will be forced to use private IP address within the local area network. Using private IP addresses
only poses a big security risk to the company network and as such there is need to ensure that the
private IP is not visible to the public users. This can be achieved by using network address translation
(NAT) to convert the several pool of private IP addresses of the devices accessing the internet to a
smaller pool of IP addresses that the internet service provider has been allocated. This ensures that the
public have no access to the private IP.
Employing the use of both public and private IP in the company network will help enhance the
network security by shielding the private IP access from the outside (Mercer, 2018). People will only see
the public Ip when devices are connected to the internet and cannot use it to trace the private IP thus
making the network more secure. This will help CAC maintain data security and ensure that they are not
accessed by unauthorized users from external networks. Thus, CAC should use both private and public
IPs in order to make the network more secure and prevent external attackers such as hackers from
gaining access to the internal network.
By adopting the use of PAT and private IP addresses, accountability-which is one of the essential
network security features is lost. This renders the network to be vulnerable to attacks from rogue users
and make it nearly impossible to track the source of the attack. As such, by combining the use of both
Public and private IP provide an excellent security solution for the company network.
In order to improve and enhance the network security, it is important to have a network
security plan. Colour Ability Corporation should adopt the following three ways which are effective in
improving the IP network security. They include: for the new network the company should implement a
zones and conduits network infrastructure. Secondly, the services that are utilized by several computing
devices should be moved to demilitarized zones. Finally, the most current best practices and IP
standards should be used. By laying out this security plan, CAC will be able to improve the network
security.

Future Plans
Color Ability Corporation expects to grow within the next 10 years and as such, the proposed
network design is flexible enough to allow for future expansion and scalability. The increasing network
needs will be accommodated without affecting the overall network infrastructure and performance.
With the proposed design, the company will be able to extend the network easily in future if need be.
Recommendations and Conclusions
Based on the justifications provided, CAC should therefor adopt this proposal to design and
implement network infrastructure for the new building. Network performance depends on the choice of
network devices, cables, and choice of the internet service provider. These are the key determinants of
network reliability, availability, scalability, expandability, and overall security. Based on these factors,
the recommended devices and ISP will be able to ensure that such requirements are met.
