6.3.6 Testout CTI 130

Which of the following are characteristics of coaxial network cable?(Select Two) A) it made of plastic or glass in the center of the cable, B) It has a conductor made from copper in the center of the cable C) It uses two concentric metallic conductors D) it is totally immune to electromagnetic interference E) the conductors within the cable are twisted around each other to eliminate crosstalk.

- It has a conductor made from copper in the center of the cable - It uses two concentric metallic conductors

A tech is replacing a cable modem. The cable from the cable company has an inner solid wire conductor and an outer mesh conductor separated by PVC plastic insulation. Which of the following network cable types is being used? 1)Twisted pair cable 2)Fiber optic cable 3)Coaxial cable 4)Straight- through cable.

3)Coaxial cable

Advantages of using fiber optic cabling for a network(pick two). A- Increase flexibility B- Immunity to electromagnetic interference C- Faster installation D- Lower installation cost E- Greater cable distances w/out a repeater

B- Immunity to electromagnetic interference E- Greater cable distances without a repeater

Which of the following BEST describes the type of cable configuration and the purpose for which it should be used? Look up the image**

Crossover cable configuration used to connect computers directly to one another for networking

What is a major benefit STP provides that UTP does not? 1)Greater resistance to interference 2)Ability to install longer cable lengths 3)lower cost 4)safer for installations in overhead ceiling spaces.

Greater resistance to interference

LC

A technician connects two network switches using a twisted pair cable. Neither switch support auto-up-linking. Which of the following identifies the TIA wiring standard required on each end of the cable? 1)both ends must only be T568B 2)one end must be T568A and the other must be T568B 3)both ends must only be T568A

One end must be T568A, and the other must be T568B

You are installing networking cable in the air space between the ceiling and the roof of a building. Which type of should you use? 1)Plenum 2)PVC 3)Multi-mode fiber 4)STP

You have recently been called to troubleshoot network connectivity problems at a user's workstation. You found that the network cable runs across high traffic areas on the floor, causing the cable to wear through and break. You have replaced the cable with a plenum-rated and shielded twisted pair cable. You would like to minimize the problem and prevent it from happening again.Which of the following will best protect the cable from further damage?

Run the cable through the ceiling area instead of across the floor
