Scenario – Designing a solution for Shine Dental Clinic (Network Solution):
Tom and Steph has recently opened a new clinic, “Shine Dental”, in Sydney, Australia. They are committed to providing quality dental services to people of all age group.
They have four full-time surgeons using surgery rooms, four assistants working with the surgeons while performing surgery, three receptionists/admin staff, completing daily paperwork, admin, client consulting and handling the front desk.
The area for the new office is 250 sqm approximately. For detailed dimensions and floorplan, refer to Figure 1.
The clinic required eight workstations, one server and a printer and needed to be installed at the following locations:
• One reception desk with space to place two computers (Workstation 5 and 6),
• One small consulting room (Workstation 7)
• One server room with extra space to place an additional computer (Server, Workstation 8)
• Four surgery rooms (Workstation 1 – 4)
The entire floor divided with each other by drywall sheets. The office is fully furnished (except computers, networking devices and cabling)
The owner of “Shine Dental” has purchased eight (8) desktop computers of the same type. Table 1 shows the sample specification.

In addition to the computers, he has also wanted to purchase one LaserJet multifunction printer for print/copy/scan/fax. The printer should have USB 2.0, Gigabit LAN, Wi-Fi(n) and other prominent printing and scanning features.
All computers/server has got a dedicated screen. In addition to that, there are four additional overhead screens attached in the four surgery rooms for patients to view local TV channels.
Those four screens are also attached to the main computers in the surgery room.
Doctors should display x-rays on the overhead screen for patients, but simply changing the input on the TV, your job is to connect the overhead screen/TV to the computer as an extended display or mirror and the Antenna.
You are also required to set up a backup for all the computers/server. All the backups should run each night and should get stored at one physical location within the premises, and a copy of the local backup has to be held on to the cloud utilizing one of the cloud services.
As a consultant, you can choose any cloud service of your choice but must justify your recommendation.
Assume that you have been hired as a network technician to help design and deploy this network.
Perform the following tasks to support this.
Task 1
To inter-connect the desktop computers and connect the overhead screens/TV with the computers and TV antenna, you have decided to use a wired network. What is the primary transmission media, connectors, adaptors you would use for this? For your recommendation of media, consider and explain the following criteria:
• Speed
• Length
• Ease of installation
• Compatibility with intermediary devices
Your answer must also include transmission media, connectors, adaptors, and other necessary devices to help you implement this successfully.
Task 2
Waiting customers should be able to access the “Shine Dental” Wi-Fi network for internet usage. What devices will you need to extend your wired network to support wireless devices with maximum speed and make sure that customers using “Shine Dental” internet do not cause interruption to the clinic’s network? Justify your answer.
Task 3
In addition to the workstations and server, the multifunctional printer needs to be connected to the network. Would you connect it via a wired media or wireless media? Justify your answer. Recommend a make and model of the multifunctional printer as per the customer requirement.
Task 4
Complete Table 5 to assign suitable static IP version 4 addresses to the devices (with subnet mask) on the network. You have decided to go with the class C private IP address range 192.168.30.0/24 (except where it is indicated otherwise).
You need to complete 3rd column of Table 5.
Device IP address IP address with subnet mask
Workstation_1 (Surgery1) 1st usable IP address 192.168.30._ ? _ /24
255.255.255._ ? _
Workstation_2 (Surgery2) 2nd usable IP address 192.168.30._ ? _ /24
255.255.255._ ? _
Workstation 3 (Surgery3) 4th usable IP address 192.168.30. ? _ /24
255.255.255._ ? _
Workstation 4 (Surgery4) 5th usable IP address 192.168.30. ? _ /24
255.255.255._ ? _
Workstation 5 (Fdesk1) 7th usable IP address 192.168.30. ? _ /24
255.255.255._ ? _
Workstation 6 (Fdesk2) 8th usable IP address 192.168.30. ? _ /24
255.255.255._ ? _
Workstation 7 (Consulting) 10th usable IP address 192.168.30. ? _ /24
255.255.255._ ? _
Workstation 8 (BDesk) 11th usable IP address 192.168.30. ? _ /24
255.255.255._ ? _
Server_9 (Server) 14th usable IP address 192.168.30._ ? _ /24
255.255.255._ ? _
Printer 192.168.200.100/24 192.168.200.100 /24
255.255.255._ ? _

Task 5
Implement the network topology (Figure 2 is a partial design to assist you) using a packet tracer. For example, it would help if you considered the following:
• All devices (Server, workstations and printer etc.) mentioned in table 5 are labelled and have their IP addresses and subnet mask configured (as per your answer in Task 4)
• Select the appropriate media in packet tracer, label the media type and use the switch 2960 with 24 ports and two-gigabit uplink ports to interconnect the Desktops
• Connect workstation_5 and workstation_6 to one of the “5 port switch” of your choice and connect the switch to the 24-port switch
• A standard wireless access point is added and configured with security. This wireless access point should be then connected to the 24-port switch via suitable wired media.
• Printer is configured and connected to the previously added “5 port switch.”
Figure 2
Task 6
Test the network using a suitable network utility and verify that workstation_7 can communicate with other workstations and servers. Provide screenshots to confirm that you have used the appropriate tools for this purpose. Use command-line utility only to test the connectivity
Task 7
Configure the most secure protocol (available in packet tracer) to authenticate three newly hired part-time employees’ “Jason”, “John”, and “Steph”, assign 21st, 36th and 43rd usable IP addresses, respectively.
Users should be able to differentiate the network before connecting to the office network easily. For example, provide screenshots and justify.
Label Jason’s laptop as “jason_laptop”, John’s laptop as “john_laptop”, and Steph’s laptop as “steph_laptop” and configure in packet tracer.
Task 8
Assume that Workstation_5 (consulting room) is a Linux box. You have run standard command-line tools and receive the following output:
Figure 3
Use Figure 3 above to answer the following questions:
- What is the IP version 4 address of this machine?
- What is the IP version 6 address of this machine?
- What is the MAC address of this machine?
- What is the default gateway?
- Ping command gives the following error below, and the site cannot be opened. Give possible explanations, and provide a solution.
Task 9
Assume that the network has been physically set up, as you have demonstrated in your packet tracer file (created in task 8).
Users have complained that none of them can print. Using the packet tracer file, troubleshoot this issue and identify what might be causing this.
Assume that the printer is mechanically functional and has no physical defect.
Identify and discuss. The answer should be based on Task 4.
Task 10
“Shine Dental” needs to store an image of all workstations and server in one location.
Backups need to run each night, two copies of the backups need to be maintained at Shine Dental premises, and another copy will be stored on the cloud.
You have decided to install NAS (Network Attached Storage) as a solution. How many hard drives would you install in NAS, and what raid Level would you use and why?
Provide a cost-effective solution for the business. Performance is not essential.
What media would you use to connect NAS to the network, and how would you connect it.
For demonstration purposes, you can include a server in packet tracer, label it as NAS, and assign it 56th usable IP address to NAS. You must provide a relevant screenshot as an example
