Chapter 3: Networking Topologies, Connectors, and Wiring Standards

1. B, C. Plenum-rated means that the cable’s coating doesn’t begin burning until a much higher temperature of heat, doesn’t release as many toxic fumes as PVC when it does burn, and is rated for use in air plenums that carry breathable air, usually as nonenclosed fresh-air return pathways that share space with cabling.

2. D. UTP is commonly used in twisted-pair Ethernet like 10BaseT, 100BaseTX, 1000BaseTX, and so on.

3. D. Unshielded twisted-pair has standards from Category 2 through 6 for use on Ethernet networks. There is no Category 8 defined.

4. C. UTP usually connects with RJ-45. You use a crimper to attach an RJ connector to a cable.

5. A. Single-mode fiber allows for the maximum cable run distances.
