a
A technician 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? A• Coaxial cable B• Straight-through cable C• Twisted pair cable D• Fiber optic cable
c
A technician is running a network above a dropped ceiling that is also used for ventilation. The cable must be twisted pair and must be capable of Gigabit Ethernet speeds. Which of the following cables should be used? A• Riser-rated CAT-5e B• Plenum-rated multimode fiber C• Plenum-rated CAT-6a D• Riser-rated RG-58

b
As a network engineer, you have been creating patch (straight-through) cables for a network switch. You have plugged in all the cables and are testing data transmission through the cables. You notice that the data transmission is not functioning properly in some of the cables and are sure that one of the cables is interfering with the transmission at the near end of the cable. What is this type of interference called? A• Router interference B• Cross-talk interference C• Wi-Fi interference D• Cat 5 Ethernet interference
b
Cable lengths are limited in distance A• Single mode B• Multimode
a
Cable lengths can extend a great distance A• Single mode B• Multimode
b
Data transfers through the core using more than one light rays A• Single mode B• Multimode
a
The core diameter is around 10 microns A• Single mode B• Multimode
a
What is a major benefit STP provides that UTP does not? A• Greater resistance to interference B• Ability to install longer cable lengths C• Safer for installations in overhead ceiling spaces D• Lower cost
d
Which connector is used with unshielded twisted pair (UTP) cable? A• DIX B• AUI C• BNC D• RJ45
b
Which kind of connector do you use to connect a modem to a standard telephone line? A• F-type B• RJ11 C• RJ45 D• RJ58
a d
Which of the following are advantages of using fiber optic cabling for a network, as opposed to other types of cabling? (Select TWO). A• Immunity to electromagnetic interference B• Increased flexibility C• Faster installation D• Greater cable distances without a repeater E• Lower installation cost
b d
Which of the following are characteristics of coaxial network cable? (Select TWO). A• It is made of plastic or glass in the center of the cable B• It uses two concentric metallic conductors C• The conductors within the cable are twisted around each other to eliminate crosstalk D• It has a conductor made from copper in the center of the cable E• It is totally immune to electromagnetic interference (EMI)
b
While sorting through a box of cables in your storage room, you find one that matches the configuration shown in the image. Which of the following BEST describes the type of cable configuration and the purpose for which it would be used? A• Rollover cable configuration used to connect computers to routers for console management. B• Crossover cable configuration used to connect computers directly to one another for networking C• Patch (or straight-through) cable configuration used to connect computers to network devices, such as switches and hubs. D• RJ11 configuration used to connect wireless routers to phone line connections.
d
You are installing networking cable in the air space between the ceiling and the roof of a building. Which type of cabling should you use? A• Multi-mode fiber B• STP C• PVC D• Plenum
a
You are using a crimper to attach an RJ45 connector to a Cat 6 UTP cable. You need to use the T568A standard to connect the individual wires to the connector. Which wire should be connected to pin 1? A• Green with white B• Orange with white C• Blue D• Green
a
You have recently been called to troubleshoot network connectivity problems at a user's workstation. You have found that the network cable runs across high-traffic areas on the floor, causing the cable to wear through and break. You are replacing 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? A• Run the cable through the ceiling area instead of across the floor B• Run the cable under the carpet C• Periodically check the cable for kinks and wear. Replace the cable when necessary D• Encase the cable in a protective shield and secure the cable to prevent it from slipping. E•
