Assessment 2: Case Study
Instructions to Students:
Read the scenario below and prepare a report that addresses all the points below. You should type (do not handwrite!) your report. Make sure you use your own words in the report, make sure you address all the requirements, and do not submit excessively long answers (no individual point should exceed 300 words).
Scenario
You are an employee of FAST, an IT networking company. You have been asked to configure and install WAN links, including setting up a VPN for a site-to-site connection, for DEF Manufacturing, a local Melbourne company with a head office in the CBD. DEF have asked you to provide them with a written report on the following matters relating to setting up WAN Links for their company. Mr. Smith, the IT Manager, has been nominated by the company as the DEF employee in charge of all aspects of the WAN implementation, and it is he who will review and approve all plans and recommendations from you.
DEF require a product that they can connect to their existing Cisco switched network and use to implement a VPN to a remote site they have in Dandenong. They have a preference for Cisco equipment but are not sure if Cisco equipment can meet their needs. They have asked you to investigate the Cisco ISR 4000 series to see if that suits their needs. The new device needs to support an IPSec-based VPN connection to their remote site, and they also need a device that can connect via ethernet to their existing switched network. They estimate that the VPN will need to support bandwidths of up to 30Mbps between the two locations.
They have some documentation for their current network, and that shows that there is a spare Ethernet port on their main switch that you can connect any new appliance into. They are not sure that the documentation is correct, however, and have asked you to verify that the port is available.
They are very safety conscious and want an assurance that all work will be done according to the relevant WHS standards. They also want to the work to be done outside core business hours of 8AM to 6PM Monday to Friday. They have advised you that their network equipment is housed in a special-purpose computer room in the basement of their head office, and that, if you want to gain out- of-hours access to that room, you will need to put in a written request to Mr. Jones, the Facilities Manager, at least 3 business days in advance of the day you want access. They want to see a plan of the work you are planning to undertake, showing what activities you will be undertaking, when you will be doing them, and what contingencies you have put in place should anything go wrong.
They are also concerned about how their IT administrator will cope with supporting the WAN links once they have been installed. Accordingly, they have asked you to briefly explain a number of router administration tasks, such as the setting up of access control lists, the use of the debug command, and two common problems encountered in configuring VPN links, They are also concerned about the move to IPv6 and would like you to explain two basic differences compared to IP v4.
In your report, you should:
1. Specify the relevant legislation, work health and safety (WHS) codes, regulations and standards that apply to your work when you are installing the WAN links
2. Describe how you are going to access the site according to DEF procedures
3. Review existing network design documentation to ensure it is current/correct, and supports your proposed solution
4. Specify what equipment you are recommending to meet their technical requirements.
5. Check availability of specified equipment, and provide a link to technical specification for the recommended components.
6. Develop plans, with prioritized tasks and contingency arrangements, for installation of components with minimum disruption to client.
7. Explain how you would liaise with appropriate person to obtain approval for the plans, including security clearance and timings.
8. Explain the purpose of configuring ACLs on a router
9. Explain the purpose of the router debug command
10. Explain two typical problems and solutions with WAN link installations
11. Explain two basic differences between IPv6 and IP v4 as it pertains to the operation and configuration of the protocol
ASSESSMENT 3 - LAB
Instructions to student:
Complete following the labs as described, Save the evidence of lab completion screen print in a separate document, clearly labelling the evidence e.g. lab 1 evidence, lab 2 evidence etc. Make sure that document has your name and student id, Print and attach it to your assessment resources summary.
Consult the resources in page-2 if you need more contextual information about particular labs.
Lab 1 Configure DHCP on a router:
Lab overview. In this lab we will configure a DHCP service on a router, and have it give out an IP address to a client.
Before you begin - key points to note
1. Recall from the lecture that DHCP offers a number of advantages over static IP address assignment. You should reflect on those advantages before commencing the lab, as you may need to nominate them in other assessment tasks for this or other units
2. You should also reflect on the basic operations of the DHCP protocol - e.g. discover, offer, request, accept (DORA) - as these could also be assessed in other tasks. Understanding how DHCP operates will also make the lab clearer while you are performing the lab.
3. You should also test your configuration e.g. verify that your DHCP client receives the expected address from the range, and troubleshoot your configuration as required.
Instructions
1. Configure the router port with the static IP address 192.168.1.1
2. Create an address pool called S123456 (where S123456 is your student id) of IP addresses in the range from 192.168.1.1 to 192.168.1.200. (subnet mask 255.255.255.0)
3. Exclude the address range 192.168.1.1 to 192.168.1.20.
4. Set DNS server to 192.168.1.20
5. Set the default-router to 192.168.1.1
6. Go into the client PC device to verify that the client has picked up the correct IP settings from the DHCP server you just configured on the router.
7. Save the requested screen shot of the router configuration into your student workbook. You can do this by running the show run command to show the router configuration. Make sure that the screen shot shows your address pool, exclusions and DHCP options for DNS server and default gateway. See example below
Lab 2 Configure NAT:
Before you begin - key points to note
1. Remember NAT is a way of mapping internal IP addresses to external IP addresses (and vice versa).
2. You should reflect on the advantages of NAT as you may be asked about these in other assessment tasks.
3. You should reflect on the basic operations of a NAT solution, and how NAT can be scaled to medium- or larger-sized networks. These could also be assessed in other tasks.
4. You should verify that NAT is occurring as you expect when doing the labs, and troubleshoot your solutions as needed.
Lab Instructions
Complete the lab as shown in parts 2 and 3 of the "Setup NAT for the Cisco CCNA w/ Packet Tracer" (see links
in page-2)
1. Once you have completed the lab as shown in parts 2 and 3 of the video, you should customize the web page being sent from the server 10.0.0.254 to add in your student id (see image below - instead of S12345 you should put your own student id)
2. After customizing the web page on server 10.0.0.254, you need to go into PC 192.168.1.100 and open the web browser to IP address 200.10.0.2 (this is shown in part 3 of the lab video). If you have done the lab correctly, the page should be shown in the browser as is shown below
You need to save a screenshot of this web page displaying correctly and copy it into the evidence for Lab 2 completion in your workbook. Your screenshot should look similar to that below (your student id will be in place instead of S12345)
Lab 3 Configure ACLs:
Lab Overview. For this lab, you will set up standard access control lists (ACLs) for your router.
Before you begin - key points to note.
1. You should reflect on the purpose and benefits of ACLs, as you are likely to be assessed on this in other assessment tasks.
2. You should reflect on how ACLs are able to filter network connections, and how this serves particular security purposes.
3. You should be prepared to test your lab configuration to ensure it conforms with what has been requested to be set up, and troubleshoot/debug your configuration as required.
Lab 4 Configure DSL:
Lab Overview. In this lab, you use Cisco Packet Tracer to set up a DSL connection to an internet provider and obtain a dynamic IP address through the DSL connection.
Before you begin - key points to note
1. You should reflect on how ASDL operates as you perform the lab, as this will help you understand the configuration tasks in the context of overall ASDL operations
2. You should reflect on the benefits and advantages of DSL/ADSL technologies, as this will both assist in understanding the lab, and may be assessed in other assessment tasks
3. You should verify your configuration by ensuring the address is configured as expected across the WAN link. Be prepared to troubleshoot the WAN link and/or the DSL connection as required.
Lab 5 Selecting a WAN link and debugging:
Lab Instructions
