Copper Cables and Connectors

You're working with an older 10Base2 Ethernet network. Which of the following connector types will you MOST LIKELY encounter? A. BNC B. ST C. RJ11 C. F-type

A. BNC

Which of the following connector types would you most likely use to connect to a T1 WAN service? A. RJ11 B. RJ48c C. RJ45 D. GG45

B. RJ48c *similar to RJ45 connector, but it has different pin-outs*

Which of the following are characteristics of a coaxial network cable? (Select two.) A. The conductors within the cable are twisted around each other to eliminate crosstalk. B. It uses RJ45 connectors. C. It uses two concentric metallic conductors. D. It is composed of four pairs of 22-gauge copper wire. E. It has a conductor made from copper in its center.

C. It uses two concentric metallic conductors & E. It has a conductor made from copper in its center

Which of the following connectors is used with Ethernet 100BaseTX networks? A. GG45 B. ST C. RJ45 D. BNC

C. RJ45

Which of the following cable types often includes a solid plastic core that keeps the twisted pairs separated? A. Cat 5e B. Cat 6 C. Cat 3 D. Cat 5

B. Cat 6 *This prevents the cable from being bent too tightly*

You've just signed up for a broadband home internet service that uses coaxial cabling. Which connector type will you MOST LIKELY use? A. RJ45 B. F-type C. RJ11 D. BNC

B. F-type

You have a small home network connected to the internet using an RG-6 cable. You need to move the router, but you can't find anymore RG-6 cabling. Which cable type could you use instead? A. Cat 5e B. RG-59 C. Cat 3 D. RG-58

B. RG-59 *RG-6 has an impedence rating of 75 ohms, its important to use coaxial cables with the same impedance rating*

Why might you use an RJ11 connector? A. You want to connect a 10GBaseT network to a switch card using a Cat 6 cable. B. You want to connect your computer to the internet with a DSL modem. C. You want to upgrade your 10BaseT network to 100BaseTX. D. You want to connect your computer to a network using a Cat 7 cable

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

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? A. Cat 5e or Cat 6a cables B. Fiber optic cables C. Plenum-rated cable D. STP cables

C. Plenum-rated cable

You're installing network 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 closer inspection, it appears very similar to the Cat 5e wiring. Is this possible? A. Yes. You can use Cat 3 cabling as a substitute for Cat 5e cabling since they're electrically identical. B. No. Cat 5e cabling uses a thicker copper wire than Cat 3 cabling, enabling higher data transmission rates. C. 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. D. No. Cat 5e cabling has more twists per inch than Cat 3 cabling, reducing crosstalk and supporting higher data rates.

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