Question
Joe, a technician, is attempting to connect two hubs to add a new segment to his local network.

Which of the following is MOST likely the problem?
Options
- AOne of the hubs is defective.
- BThe new hub is powered down.
- CThe patch cable needs to be a CAT6 patch cable.
- DThe technician used a straight-through cable.

Explanation
The technician used a straight-through cable (D), which is the problem. A straight-through cable is used to connect unlike devices (e.g., computer to switch/hub). When connecting two like devices - hub to hub or switch to switch - a crossover cable is required so that the transmit pins on one device align with the receive pins on the other. Without a crossover cable (or an uplink/MDI-X port), the hubs cannot properly communicate. The fact that devices within the new segment can reach each other confirms the new hub is powered and functional (ruling out A and B). CAT5 (C) is sufficient for this connection; upgrading to CAT6 would not fix a wiring configuration problem.
