a. Small LAN
b. Large LAN
c. WAN
d. VPN
e. VLAN
f. WLAN

2. Explain the difference between a router and a modem. Explain the function of a modem in a WAN.

3. Describe three types of modems.

4. Explain the purpose of IP addresses as part of a WAN.

5. Explain how packet switching works within a WAN.

6. Explain how routers work.

7. Explain routed protocols and give three examples.

8. Explain routing protocols and give three examples.

9. Explain the function of a TCP.

10. Explain the concept of double data rate (DDR)

12. Explain the advantages and disadvantages of WAN so as to assist a company in making that decision about constraints and costs associated with each.

13. Explain the difference between Synchronous Transmission and Asynchronous Transmission. Give examples of each.

14. Describe two constraints associated with establishing a WAN, including an explanation of how the constraints affects network design.

15. Explain the key features of digital and analogue networks and give the key differences between each.

16. Explain the process a network manager must follow to ensure growth projections are accurately forecasted and capacity is effectively planned.

17. Explain at least two considerations for a business when deciding on whether to opt for low or high- speed links.

18. Explain the difference between LAN and WAN protocols.

19. Explain two considerations for a business when determining redundancy paths for a WAN.

20. Explain the importance of response time and reliability for a WAN.

21. Explain two methods that can be used to ensure the security of a WAN.

22. Explain why it is important to assess traffic load and flow patterns when establishing a WAN.

23. Explain why it is important to assess users and expected applications when establishing a WAN.

Assessment Task 2: WAN specification project

Task summary
In this assessment task, you are required to identify the best way computers and local area networks (LANs) can be connected to make a wide area network (WAN) for a case study organisation.

Carefully read the following:

Complete the following activities:
1. Identify WAN needs and create a WAN specification.
You are required to review the network topology diagram for the existing office in Sydney, as well as the new office in Brisbane.
Based on your review of the network topology diagram, you are required to develop a WAN Specification that includes:
• A description of the current LAN that is in place in each office.
• Required LAN, WLAN and VPN segments for the proposed WAN. Make sure you identify the segment, as well as what should be included in each segment (use screen shots to show your proposed segments).
• An explanation on how the company's physical environment impacted on the WAN design created.
• Your estimate of the bandwidth required according to the scenario information and based on expected traffic content and volume. You should also include the download and upload speed required.
• An outline of the various components of the proposed WAN network and that includes the device/software, resource type, segment/level and functions. Use the table in the WAN Specification Template to document your answers.
• Vendor options and costs for each of the components you are proposing (include at least three options).
• An outline of the most appropriate WAN design taking into account budget considerations, reliability and bandwidth.
• A design for redundant links in the proposed WAN connectivity for link backup purposes, in case the main link is disrupted.
Use WAN Specification Template to document your report. Ensure you include screen shots of each part of the WAN design.
