As a consultant for the First National Bank of Monroe, you have been asked to update the IP addressing scheme for the bank's regional office as well as its two smaller branches. Nodes added within the last 2 years use DHCP, but some of those installed before then have statically assigned IP addresses. The network has grown from 24 workstations and three servers to 48 worksta- tions and six servers in that time, all of which are running Windows operating systems. Describe what types of problems could result from having a mix of statically assigned and dynamically assigned addresses on the same network. Then describe the steps you would take to change the address assignment properties for a Windows XP workstation. Is there a way you could modify the addressing properties of the workstations at each small office remotely, without having to visit those offices? Why or why not?
Case Project 3-2
While you were gathering information to recommend transmission media for the medical instrument manufacturer, you noticed that some of the telco rooms were in disarray. For one thing you notice sloppy cable terminations.
Further, cables are pulled tightly around the corners of racks and intertwined.
You also suspect that the horizontal wiring spans exceed TIA/EIA 568 recommendations.
And to top it off, cables, ports on connectivity devices, and data jacks aren't labeled. However, the company's network manager tells you she and her staff don't have time to attend to these oversights. What can you say to convince her that the minor oversights could have a significant impact?
What do you consider the single most important reason to pay attention to faulty terminations and excessive horizontal wiring spans? Why is it critical to label patch cables, ports, and data jacks?
Case Project 3-3
Thanks to your persuasive skills, the medical instrument company took a few days to improve its cable management practices. That's fortunate, because now, several months later, it has just won a huge contract and its network will expand. The brand-new warehouse is busy with activity. The inventory shelves are being stocked to the ceiling. Nearby, machines that carry merchandise along a conveyor belt are working nonstop. However, the company has a new problem: since production has stepped up, several inventory specialists in
the warehouse are complaining that occasionally their handheld computers will not connect to the network or that they suddenly lose their connection.
It's especially frustrating because more personnel than ever are trying to use the network. What could be causing the handheld computers to experience intermittent connectivity problems? What can you do to rule out the possibility that the handheld computers are simply faulty?
