IT Assignment

Questions : 1.Write a 1000 words (+/- 10%) report explaining: a.The detailed design of a simple addressing solution (with diagram(s) and step by step workout of the calculations) that leaves room for growth, is easy to administer and has the minimum wastage of available IP address space. b.Explain what happens to your design if the number of hosts per network jumps to over 1,024 per building. 2.Currently the company policy does not allow the use of network analysers on the organisational network. You have recently had a team meeting where all the staff are of the view that the use of network analysers can bring more efficiency in troubleshooting processes. Write an 800 words (+/- 10%) report for the board of directors proposing to allow the use of network analysers for diagnostic purposes in new proposed network architecture. Your report should include: a. Brief explanation of protocol in the context of communication networks and the role of network analysers. Explanation should include example of a situation where network analysers can be used in the context of Task 1. b. An analysis of currently available network analyser tools. The analysis should contain: i. Benefits, associated costs, ease of usability ii. Recommendation from you, as to what tool would you prefer to use and why. 3.This is a practical assessment and will enhance and test your practical skills related to the subject topic. You are required to set up a simple network using minimum three PCs and minimum two routers, or use simulation software to set up the same network. Task : You are required to set up a network consisting of PCs, routers and servers. You need to configure routing between routers (minimum two routers required). The routers will have multiple network interfaces. The PC (client) will be connected to one of the router's interfaces and other PCs (servers) will be connected to the second router's interface. Client <--> Router <--> Router <--> Server(s) Setup separate server for each application/service. Each side of the router will be in its own LAN (or WAN) segment and should have a different network address, use ONLY private IP address ranges to design this network. Perform the following activities and support your workings with screenshots 1. Configure the PC, Server and Router interfaces with appropriate network addressing; 2. Configure routing (IP packet forwarding) on the routers; 3. On the client ping the client's own network interface, then the local router gateway interface, then the remote router interface, then the server; Task 2 - Configuring Network Services Using the same network topology that you have setup in Task 1, perform the following additional activities 1. DHCP: Configure DHCP on the server and show that the client PC has successfully received an IP Address and other network parameters (default router, netmask, DNS) using DHCP; 2. WEB Server: Configure a WEB server on dedicated machine, with URL as www.YOUR NAME.csu.edu.au 3. DNS: Configure a DNS Server on the server device and demonstrate that forward and reverse DNS are working from the client PC; test DNS Server by browsing www.YOUR NAME.csu.edu.au from client PC, DNS must resolve this URL to IP address of WEB Server 4. Firewall: Configure traffic filtering on the router to block TCP traffic only between one of the client PC and WEB Servers, and provide evidence of such traffic filtering. A series of screen shots with commentary on each of the required tasks is to be submitted. The submission must include a comprehensive explanation of each task and all the commands used along with the output (or final result) in report format.
