A connection to the WiFi is required if you want to send email or use the browser. Generally, increasing the capacity of the hard disk in a new computer can help make applications can run faster." What likely terminology or conceptual mistakes are there? What better suited terminology should they have used and why? Your answer: Your question: Your sample answer: Week Two Assignment Question: An office LAN has twenty workstations. The office manager has asked you to replace their 100Mbps wired switch with a wireless access point (AP) capable of 200Mbps. Will this increase or decrease the bandwidth available to each workstation? Explain your reasoning by including estimates of effective bandwidth for each case. Your answer: Your question: Your sample answer: Week Three Assignment Question: CSMA/CD on a physical bus and CSMA/CA over Wi-Fi operate in a very similar way and do very similar things. However, they do operate differently. If CSMA/CA is used in a wired copper network segment, the network communication would still function. However, there would be some issues arising. Identify and describe two key issues. Your answer: Your question: Your sample answer: Week Four Assignment Question: With the worry of computer viruses and a greater demand for higher bandwidth by computer users, it appears that fibre optic cables may be a good physical media solution instead of UTP cables because fibre optic cables can provide higher bandwidth and a more secure network connection for an intranet. What possible technical or operational issues are there with this reasoning for selecting cables for use at the access level connection in a LAN? Provide three applicable reasons with your explanation. Your answer: Your question: Your sample answer: Week Five Assignment Question: An organisation has a fixed number of public IPv4 addresses it uses for connection to the Internet. This limits the number of computers the organisation can assign that connects to the Internet. What addressing solution can the organisation apply so that more of its computers can be connected to the Internet? What is this mechanism called? Give a clear explanation, not exceeding 350 words, on why this solution works. Your answer: Your question: Your sample answer: Week Six Assignment Question: The network was designed using a layered architecture. Each layer has a specific function or task to support its upper layer. The collection of these specifications is called a protocol stack or suite. Complete the following table by first arranging the tasks in order from the upper layer to the lowest layer. Then identify the layer names, then common network devices associated with those layers, and describing typical standard protocols used in the stack. The given tasks (to be correctly reordered in the table by the student) for the given layers are: • Determines the path that messages take between clients and server over the network • Transmit and receive data frames • Ensures that the information sent by a server reaches a client • Permit a client-side file transfer software and the file server software to understand messages sent between them Your answer: Task Layer Device Protocol Your question: Your sample answer: Week Seven Assignment Question: A switching table below has the following entries: MAC Address Port # 00-25-2A-00-00-01 4 00-25-2A-00-10-FC 1 00-25-2A-00-00-2B 2 00-25-2A-00-11-21 3 Port 3 is connected to a hub. The following events occur: 1. The entry for 00-25-2A-00-00-2B expires. 2. An addition device (00-25-2A-00-10-E0) is connected to the hub on port 3. 3. A new virtualised machine (00-25-2A-00-10-0C) is started on the server connected to port 1. 4. Device (00-25-2A-00-11-21) is disconnected from the hub on port 3 and connected to port 2. Your answer: MAC Address Port # Your question: Your sample answer: Week Eight Assignment Question: In a recent stock clearance sale, an electronics store had reduced prices for a wireless access point. This particular product was small in size but had a powerful transmitter for longer range connection, used only WEP for encryption, had a very fast processor and a large capacity memory. Why would this product not be suitable for use a small office network today? What feature should be available to make it appropriate for use? Your answer: Your question: Your sample answer: Week Nine Assignment Question: Small businesses require several common applications that support their needs such as accounting and database software. Discuss issues a small business owner would need to consider in deciding whether to use either an in-house managed database server or an out-sourced Saas. Identify three key issues. Your answer: Your question: Your sample answer: Week Ten Assignment Question: A SOHO network design has to connect about a dozen workstations and two to three network servers. Would an all wireless network design be a practical solution here? Identify two issues and give clear explanations.
