1. Plenum and coaxial cable are not common cables used today. 2. A decibel is the unit of measurement that is a tenfold logarithmic ratio of power output to power input. 3. Frequency increases does not contribute to attenuation. 4. Mutual crosstalk is not a type of crosstalk. 5. The Federal Communications Commission (FCC) is part of the US government. 6. The National Fire Protection Association (NFPA) is responsible for the development and publication of the National Electric Code. 7. A telecommunications room can sometimes be referred to as a telecommunications room or a wiring closet. 8. Backbone cabling includes cabling between equipment rooms and building entrance facilities, in a campus environment it is the cabling between buildings’ entrances facilities, and vertical connections between floors. 9. The hub network architecture is not commonly used today. 10. 10Base-T networking only requires 2 wire pairs of an eight-pin modular jack. 11. According to the NEC, Article 800.100, primary conductors shall be grounded, the grounding conductor shall be insulated and listed as suitable for the purpose. 12. Knowing and following the electrical ad building codes helps protect the buildings occupants, helps when working with local, city, country, and state officials, and helps when working with electricians and contractors. 13. Patch cables are generally considered the weakest link in a network setup. 14. The security of a locking door is a benefit of a full equipment cabinet. 15. Punchdown blocks are generally used for telephone and data systems. 16. Crimpers are used to attach connectors to twisted-pair cable. 17. Fish tape and fiberglass pushrods are helpful when running cable through walls. 18. Cable-toning tools can be used to test continuity. 19. Wire-pulling lubricant is used to allow cables to slide easily over surfaces during a pull. 20. Stud finder, hammer, wrenches are all handy tools to carry with you. 21. If the tip wire in your pair is blue/white you can expect the ring to be blue. 22. There are 25 wires in a binder group. 23. High attenuation is not a benefit of coaxial cable. 24. Making a patch cable yourself is not best for your network. 25. When pulling cable bending at 90 degrees can damage them as well as twisting the cable too tight, and removing excess amounts of the cable jacket. 26. Electromagnetic interference can be prevented by making sure data cabling his at least 6 inches away from lightning rods. 27. The main difference between fiber optic and copper media is FO transmits data by digital light pulses, and copper transmits data through electrical voltage transmissions. 28. One disadvantage of fiber optic to copper is the cost of fiber optic. 29. Strand, buffer, strength members, shielding, outer jacket, coating, cladding, core are all components of fiber optic. 30. Kevlar is added to fiber optic cabling to strengthen it. 31. Optical capacitance is not a fiber rating used to choose fiber optic cable. 32. When installing fiber you should always match the rating of the cable to the equipment used and terminate the fiber. 33. An outlet box is the most common wall plate mounting in commercial applications. 34. You must consider the number of jacks, types of jacks, and labeling on a fixed design wall plate. 35. A disadvantage of biscuit jacks is they are not rated for high speed data. 36. Using the wrong type of cable/connectors can cause intermittent connection errors after your system is running. 37. You would use a BNC crimper to attach a BNC connector. 38. You do not need a hub in a standard network installation. 39. Routers work on the Network layer of the OSI model. 40. Transistor radios do not work with infrared technologies. 41. Line of sight is need for infrared technologies, meaning there is weather attenuation. 42. Radio frequency is not able to be used long range. 43. Microwave communication can be expensive to use. 44. Successful cable installation is done using proper design and quality materials. 45. Proper design includes flexibility, longevity, and ease of administration.
