Information about how you should complete this assessment can be found in Appendix A of the IT Works Student User Guide. Refer to the appendix for information on:

where this task should be completed

Note: You must complete and submit an assessment cover sheet with your work. A template is provided in Appendix B of the Student User Guide. However, if your RTO has provided you with an assessment cover sheet, please ensure that you use that.

This assessment task requires you to determine best-fit topologies for three Wide Area Networks (WANs). You can complete this project based on the networks, equipment and information provided by your assessor or for a business that you are working for.

If you choose to complete the project based on a business of your choice, it is important that you can access design documents relating to LANs to be incorporated into the WAN, network monitoring tools and network design tools, as well as equipment specifications and vendor product details and costs. Speak to your assessor to get approval if you want to base this on an organisation of your choice.

Prior to commencing the task, you are to meet with the client to find out about WAN needs. This will ensure you have all of the information you need to determine best-fit topologies for three wide area networks.

At the meeting, you will need to find out about:

scope of the work to be completed

current and future operational needs that impact on the WAN

budget available

stakeholders

other details including site access arrangements and timelines.

During the meeting, your assessor will be looking to see that you can demonstrate oral communication skills including:

speaking clearly and concisely using relevant language.

using questioning techniques to confirm information

using active listening techniques to confirm information.

At the meeting, make sure you ask questions to find out the information you need, as well as discuss some preliminary ideas and thoughts you have on the clients needs. You should ensure that all arrangements for accessing the site are confirmed at the meeting by finding out the information you need to.

Following the meeting, work on Section 1 of your Portfolio to include the information that you have been provided at the meeting.

You are now to continue to work on determining WAN needs assuming you are now on site. You are to:

Identify different LAN, wireless local area network (WLAN) and virtual private network (VPN) segments of each of the proposed WANs.

Conduct a functional analysis and determine segment needs

Estimate traffic content, volumes and organisational usage

Develop an organisational WAN functional matrix.

Complete Section 1 of your Portfolio.

You are to create a WAN specification. This is to include:

Details of the LAN, WLAN and VPN segments and associated resources requirements.

An explanation of how the physical environment has impacted on WAN design.

An outline of the WAN design that will cater for the amount and type of network traffic.

A design for redundant links in the proposed WAN connectivity for link backup purposes, in case the main link is disrupted.

Complete Section 2 of your Portfolio which will include a report on the most viable network topology for each WAN.

Make sure you have completed all sections of your Project Portfolio, answered all questions, provided enough detail as indicated and proofread for spelling and grammar as necessary.

Submit to your assessor for marking.
