Scenario

Designing a solution for Shine Dental Clinic (Network Solution)
 
Tom & Steph has recently opened a new clinic “Shine Dental” in Sydney, Australia. They are committed to provide quality dental services to people of all age group.
 
They have four (4) full-time surgeons using surgery rooms, (4) assistants, who will be working with the surgeons while they are performing surgery and, (3) receptionists/admin staff, who will be performing daily management of paperwork, admin, client consulting and also handle front desk.
 
The area for the new office is 250 sqm approximately. For detail dimensions and  floor-plan refer to Figure 1
 
The clinic requires 8 workstations, 1 server and a printer and needed to be installed at the following locations:
 

  • One reception desk with space for to place 2 computers (Workstation 5 & 6),
  • One small consulting room (Workstation 7)
  • One server room with an 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. Office is fully furnished. (except computers, networking devices and cabling)

In addition to the computers, he has also want 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 4 additional overhead screens attached in the 4 surgery rooms, for patients to view local TV channels while dental surgery is being performed on the patients. Those 4 screens are also to be attached to the main computers in the surgery room, so that when surgeons need to display x-rays to show their patents laying on the bed, patents don’t need to get off the bed to see what the x-rays would look like. Doctors should be able to display x-rays on the overhead screen for patients, but simply changing the input on TV, your job is to connect the overhead screen/TV to the computer as extended display or mirror, and also to the Antenna
 
You are also required to set up 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 stored on to the cloud utilizing one of the cloud services. As a consultant you can choose any cloud service of your choice, but must provide justification for your recommendation.
 
Assume that you have been hired as a network technician to help in the design and deployment of this network.
 
Perform the following tasks to support this.
 

Task 1

To interconnect 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 main transmission media, connectors, adaptors you would use for this? For your recommendation of media, justify your answer by addressing the following
 

  • 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
 
*Tip: You may answer in a form of table to include images, specifications, connections and explanation etc. to help you cover all points above
 

Task 2

Waiting customers, should be able to access “Shine Dental” WiFi network for internet usage.
 
What measures would you take, to make sure that customers using “Shine Dental” internet do not cause interruption to the clinic’s network
 
Explain your answer with example, specification, diagram or IP addressing scheme
 
 
 

Task 3

 
What are the devices you will need to extend your wired network to also support wireless devices with maximum speed?
 
Justify your answer

Task 4

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 the wireless media?
 
Justify your answer. Recommend a make and model of the multifunctional printer as per the customer requirement
 

Task 5

Complete Table 5 to assign suitable static IP version 4 addresses to the devices on the network. You have decided to go with the class C private IP address range 192.168.100.0/24 (except where it is clearly indicated otherwise).
 
 

Device               IP address
Workstation_1 (Surgery1) 1st usable IP address
Workstation_2 (Surgery2) 2nd usable IP address
Workstation _3 (Surgery3) 4th usable IP address
Workstation _4 (Surgery4) 5th usable IP address
Workstation _5 (Fdesk1) 7th usable IP address
Workstation _6 (Fdesk2) 8th usable IP address
Workstation _7 (Consulting) 10th usable IP address
Workstation _8 (BDesk) 11th usable IP address
Server_9 (Server) 14th usable IP address
Printer 192.168.200.100/24

 
 
Table 5
 
 
 

Task 6

“Shine Dental” needs to store an image of all workstations and server in one location. Backups need to run each night, 2 copies of the backups needs 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 & why? Provide a cost-effective solution for the business, performance is not important
 
What media would you use to connect NAS to the network and how would you connect it.
For demonstration purposes you can include a computer or a server in packet tracer and label it as NAS and assign it 13th usable IP address to NAS. Must provide relevant screenshot as an example.
 

Task 7

Wirelessly configure the most secure protocol (available in packet tracer) to authenticate 2 newly hired parttime employees “John” & “Steph”, assign 16th and 17th usable IP addresses simultaneously. Users should be able to easily differentiate the network prior to connecting to the office network. Provide screen shots and justify.
 
Label John’s laptop as “john_laptop” and Steph’s laptop as “steph_laptop” and configure
 

Task 8

Implement the network topology (Figure 2 is a partial design to assist you) using packet tracer. You need to consider the following.
 

  • All devices (Server, workstations, NAS & printer etc.) have their IP addresses and subnet mask configured, (as per your answer in Task 5, 6 & 7)
  • Select the appropriate media in packet tracer and label the connections between the nodes considering your answers in Tasks 1,2 and 3.
  • Use the switch 2960 with 24 ports and two gigabit uplink ports to interconnect the Desktops. (must connect workstation5, workstation6 & printer to one of the “5 port switch” of your choice & 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 a suitable wired media.  Printer is configured and connected

 
 

Task 9

Test the network using a suitable network utility and verify that all devices can communicate with one another. Provide screen-shots to verify that you have used the suitable tools for this purpose. Use command line utility only to test the connectivity
 
 

Task 10

On pinging to the server, all computers get reply in 1 ms, but Workstation6 get reply in more than 1 ms. See ping results below and explain your observation. Provide a solution if you identify an issue.
 
 
 

Task 11

Assume that Woskstation_5 (consulting room) is a Linux box. You have run common command line tools and receive the following output (Figure 3).
 
 
 
 
 
Use Figure 3 above to answer the following questions:
 

  1. What is the IP version 4 address of this machine?
  2. What is the IP version 6 address of  this machine?
  3. What is the MAC address of this machine?
  4. What is the default gateway?
  5. Ping command gives following error below and site cannot be opened, give possible explanations, provide solution if any

 
 
 

Task 12

Assume that the network has been physically setup 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 a mechanically functional printer and has no physical defect.
 
Identify and discuss, answer should be based on Task 5
 

Task 13

 
3rd part time employee “Jason” complain that he is unable to connect to the wireless network. He assumed his laptop should be able to directly find the necessary wireless access-point and connect without any intervention. Troubleshoot using the packet tracer file and explain to him what might be the cause of the problem.
 
Add additional device, label it as “Jason_laptop” in packet tracer to demonstrate
 
 
When you have completed, submit the solutions to these tasks via the Upload link in CSE1SIX Assessment: Networking Assignment on the LMS. You should submit the following:
 

  • Submit your Cisco Packet Tracer based project, named as xxx_cse1six_assessment2.pkt (where xxx is your student number).

 

  • Submit your answers to the relevant tasks in a single Word document called xxx_cse1six_assessment2.docx (where xxx is your student number) with  clearly labelled headings for each task.
