Chapter 20: Management, Monitoring, and Optimization

1. C. UTP cables use an RJ-45 connector. RJ-11 and RJ-25 are often used for terminating telephone lines.

2. B. Straight-through cables, known as drop cables or patch cables, will have the pins in the same order on both connectors.

3. B. On a crossover cable, one connector has flipped the wires. Specifically, pins 1 and 3 get switched, and pins 2 and 6 get switched.

4. C. If you are going to make your own UTP cables (drop/patch cables) to customize length, you need to make sure that the right wires get to the right pins.

5. A, B, C, D. A baseline is the standard level of performance of a network component or a system of components. For networks and networked devices, the four key components are hard disk, memory, processor, and network adapter.
