Question #4
You are installing networking wiring for a new Ethernet network at your company's main office building. The project specifications call for Cat 5e UTP network cabling and RJ45 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 Cat 3 network cable in storage. Upon investigation, it appears very similar to Cat 5e wiring. Should you use Cat 3 cabling as a substitute for Cat 5e cabling to finish the project?
A.   No. The sheath surrounding Cat 5e cable is much thicker than the Cat 3 sheath, creating an extra layer of shielding that reduces cross-talk and supports higher data rates.
B.   No. Cat 5e cabling uses a thicker copper wire than Cat 3 cable, enabling higher data transmission rates.
C.   No. Cat 5e cabling has more twists per inch than Cat 3 cabling, reducing cross-talk and supporting higher data rates.
D.   Yes. You can use Cat 3 cabling as a substitute for Cat 5e cabling, as they are electrically identical.
E.   No, Category 3 cabling doesn't support RJ-45 connectors.
Question #5
You are adding new wires in your building for some new offices. The building has a false ceiling that holds the lights and provides an air path for heating and air conditioning. You would like to run your Ethernet cables in this area. Which type of cable must you use?
A.   Fiber optic cables
B.   Cat 5e or Cat 6a cables

D.   You want to connect your computer to the internet with a DSL modem.
Question #7
When would you typically use an RJ11 connector?
A.   When using Cat 3 cables
B.   When using multi-mode fiber optic cables
C.   When using Cat 5 or higher cables
D.   When connecting a phone to a phone line
E.   When using RG-6 cables
F.   When using single-mode fiber optic cables
