Your company has a branch location using an Ethernet hub network. Congestion issues are becoming a serious problem as the company adds more services to the network. Currently, each of the four floors has one or more hubs in a wiring closet supporting 30-35 computers except the ground floor, which has 65 computers. All 8 printers are plugged into the hubs also.
The four floors plug into an 8-port 10 Mbps switch that the company added earlier to reduce the congestion problems. Although that solution was a major improvement, it cant keep up all of the time. The two servers and router to the Internet also connect to the 8-port Hub.
The branch cabling is relatively new and certified to CAT 5 standards. The company isnt interested in any major cabling changes at this time.
At least 75 percent of the 160 current workstations have NICs with 10, full-duplex capabilities but need to be updated. All laptop computers have the newer NICs. The other 25% of the computers have newer 10/100 full-duplex NICs.
The requirements include the following:
§ Replace all hubs with switches that are manageable.
§ Replace the 10 Mbps NICs for existing desktop PCs.
§ Each host connection should be 10/100 Mbps minimum can be higher.
§ What options are available for further enhancements in the future?
§ List all prices and where you found the reference to all products used.
What Hubs need to be replaced and Why? Are there higher bandwidth options for connecting the two servers? If so what options are there and at what cost to the company.
What options are there for the wireless connections for Laptops?
This is an exercise to get you to think outside of the box you might have to do some research and test what you have started to learn.
While your desire to become Cisco certified is admirable, does it really mean anything if you don't put forth the effort? I see no evidence that you've attempted to figure this problem out on your own. Instead, you've chosen to paste the problem verbatim from a CCNA text.
I can safely say that no one who has the knowledge and put forth the work required to earn their own certification is going to hand you the answer on a silver platter for several reasons.
If you showed that you'd put in a significant amount of effort already you'd probably get a much more amenable response here.
