Case Problem 10-3
Your ISP has requested that you return the two Class C network addresses that it assigned to your company ten years ago. They will allocate to you six externally routable IP addresses for any external-facing systems. How will you allocate the six IP addresses among the externally facing sys- tems and devices that require Internet access? How will user workstations be able to access web servers on the Internet? Case Project 10-2: Wireless Network Survey As a consultant with the Sleuth Security Consulting Co., you have been asked to perform a wireless access point survey at the Good Software Company offices. Good Software is concerned that there may be rogue (unauthorized) WiFi access points in use in their company. What tools will you use to look for rogue access points? Will you use a WiFi sniffer such as Netstumbler? What are the pros and cons of using this tool? Will you perform any LAN searches for rogue access points? Case Project 10-3: Network Evaluation As a consulting network engineer for the Excellent Network Consulting Co., you have been requested to perform an evaluation of the data network at the Zoom Trucking Company, which has just moved into an eighty-year-old office building. Zoom Truckings network engineer has not been able to get the network func- tioning on the network cable that was in the building when Zoom Trucking moved in. Part of the network uses coaxial thinnet cabling, and part of it uses Cat-3 network cabling. Less than half of the user workstations connected via Cat-3 cabling are working, and none of the workstations connected to coaxial cable are working because none of the user workstations have the right connectors. Some specifics about Zoom Trucking: Employees with workstations: 75 Servers: 8 servers located in a server room Building size: 2 floors, 100 200'x' Construction: wood frame and masonry exterior Your job is to create a list of recommendations to Zoom Trucking: what steps should it take to get its data network working as soon as possible?
