computers and 1 server within 3 months. You want to reduce network utilization. The
following table summarizes your current network configuration.
| Servers | 3 |
| Client Computers | 120 evenly distributed among the 3 servers |
| Network Type | 10BaseT Ethernet |
| Protocol | TCP/IP |
| Cable | Category 3 UTP |
| Routers | None |
| Bridges | None |
Required result:
You must reduce network utilization by 50 percent.
Optional desired results:
You want to allow for continued network growth.
You want to maintain the new network utilization levels even after the
planned additions to the network are implemented.
You want to minimize costs for the project.
Proposed solution:
Replace all 10BaseT hubs with 100BaseT hubs. Replace all Category 3 UTP cable with Category 5 UTP cable. Replace all 10BaseT network adapters with 100BaseT network adapters.
Which results do the proposed solution produced?
A. The proposed solution produces the required result and produces all of the optional desired results.
B. The proposed solution produces the required result and produces only 2 of the optional desired results.
C. The proposed solution produces the required result but does not produce any of the optional desired results.
D. The proposed solution does not produce the required result.
58. In the past year, you have added 55 client computers to your l0BaseT Ethernet network. Users of the network report that network response is slow during peak hours of usage.
Which solution is the most economical?
A. Replace all Ethernet adapters with FDDI adapters.
B. Replace all Ethernet concentrators with Ethernet switches.
C. Replace all Ethernet components with 100-Mbps ATM equivalents.
D. Replace all Ethernet components with 16-Mbps
token-ring equivalents.
