A company hires you to build a network to support 20 PCs and an IBM mainframe computer. The office is already wired with shielded twisted-pair cabling that matches IBM Type 3 specifications.
Required result:
The network must accommodate all computers.
Optional desired results:
The network should support transmission speeds up to 100 Mbps.
The network must be easy to configure.
Proposed solution:
Implement an Ethernet network using the Type 3 cable already in place.

|
|
|
|
The proposed solution produces the required result and produces both of the optional desired results |
|
|
|
The proposed solution produces the required result and produces only one of the optional desired results |
|
|
|
The proposed solution produces the required result but does not produce any of the optional desired results |
|
|
|
