Networking 2 Midterm Study Guide

Should you use the Cat 3 cabling as a substitute for the Cat 5e cabling?

• Yes. You can use Cat 3 cabling as a substitute for Cat 5e cabling since they're electrically identical.

• No. Cat 5e cabling has more twists per inch than Cat 3 cabling, reducing crosstalk and supporting higher data rates.

• No. Cat 5e cabling uses a thicker copper wire than Cat 3 cabling, enabling higher data transmission rates.

• No. The sheath surrounding Cat 5e cabling is much thicker than the Cat 3 sheath, creating an extra layer of shielding that reduces crosstalk and supports higher data rates.

Which of the following cable types often includes a solid plastic core that keeps the twisted pairs separated?

• Cat 6

• Cat 5e

• Cat 3

• Cat 5

You're 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'd like to run your Ethernet cables in this area. Which type of cable must you use?

• STP cables

• Plenum-rated cable

• Cat 5e or Cat 6a cables

• Fiber optic cables

Why might you use an RJ11 connector?

• You want to connect a 10GBaseT network to a switch card using a Cat 6 cable.

• You want to connect your computer to the internet with a DSL modem.

• You want to upgrade your 10BaseT network to 100BaseTX.

• You want to connect your computer to a network using a Cat 7 cable.

Which of the following connectors is used with Ethernet 100BaseTX networks?

• ST

• BNC

• GG45

• RJ45

Which of the following are advantages of using fiber optic cabling for a network? (Select two.)

• Immunity to electromagnetic interference

Which of the following are characteristics of an LC fiber optic connector? (Select two.)

• They use a housing and latch system similar to an RJ45 UTP connector.

• They use a one-piece bayonet connecting system.

• They can be used with either fiber optic or copper cabling.

• They are half the size of standard connectors.

Which of the following connectors is used with fiber optic cables and requires that you use a twisting motion to connect it?

• SC
