You are adding new wires in your building for some new offices. The building has a false ceiling that holds the lights. You would like to run your Ethernet cables in this area. Which type of cable must you use? A Fiber optic B pvc C srp D Plenum E Cat 5e or Cat 6e
D Plenum
Which of the following applications is more likely to justify the investment in Category 6 cable? A E-maiI B Instant Messaging C Printing D Streaming video
D Streaming video
Which of the following cable types often includes a solid plastic core? A cat 5 B cat 3 C Cat 5e D cat 6
D cat 6
You are installing networking wiring for a new Ethernet network at your company’s main office building. The project
specifications call for Category 5 UTP network cabling and RJ-45 wall jacks. Near the end of the project, you run out
of wire before the last few runs are complete. You have a spool of Category 3 network cable in storage. Upon
investigation, it appears very similar to Category 5 wiring.
Should you substitute Category 3 cabling for Category 5 cabling to finish the project?
A No, Category 5 cabling has more twists per inch than Category 3 cabling to reduce cross—talk and support higher
data rates.
B No, Category 3 cabling doesn’t support RJ-45 connectors.
C No, Category 5 cabling uses a thicker copper wire than Category 3 cable; enabling higher data transmission
rates.
D No, the sheath surrounding Category 5 cable is much thicker; creating an extra layer of shielding to reduce
cross—talk and support higher data rates.
E Yes, you can substitute Category 5 wiring with Category 3 wiring, as they are electrically identical
A No, Category 5 cabling has more twists per inch than Category 3 cabling to reduce cross—talk and support higher
data rates.
Which of the following are characteristics of coaxial network cable? (Choose three.)
A It uses two concentric metallic conductors.
B It uses two concentric conductors made from plastic or glass which conduct light signals.
C It uses RJ-45 connectors
D It has a conductor made from copper in the center of the cable.
E The ends of the cable must be terminated.
F It is composed of four pairs of 22—gauge copper wire.
G The conductors within the cable are twisted around each other to eliminate cross—talk.
A It uses two concentric metallic conductors.
D It has a conductor made from copper in the center of the cable.
E The ends of the cable must be terminated.

You have a small home network connected to the Internet using an RG-6 cable. You need to move the router connecting the network to the Internet, but can't find any RG-6 cable. Which cable types could you use instead? A RG-59 B RG-8 C RG-8, RG-58, or RG—59 D RG-58 or RG-59 E RG-58 F RG-8 or RG-58
A RG-59
Which of the following are advantages of using fiber optic cabling for a network, as opposed to other types of cabling?
