Cat 6

You are building network cables and attaching RJ45 connectors to each end. Which tool do you need for this task?

Crimping tool

What is the point where the service provider's responsibility to install and maintain wiring and equipment ends, and the customer's responsibility begins?

Demarc

You have a network that occupies both floors of a building. The WAN service provider has installed the line for the WAN service in a wiring closet on the main floor. You have a second wiring closet on the second floor directly above the wiring closet that holds the demarc. Which of the following terms describes the closet on the second floor?

IDF (intermediate distribution frame)

Which of the following are advantages of using fiber optic cabling for a network? (Select two) Immunity to electromagnetic interference No special training or equipment is required Lower installation cost Greater cable distances without a repeater

Immunity to electromagnetic interference Greater cable distances without a repeater

Which recommendation should you follow while using 110 blocks for connecting Cat 5 and higher data cables? Keep wire pairs twisted up to within one-half on an inch to the connector Use C-5 connectors Connect wires using the T568B standard Connect wires using the T568A standard

Keep wire pairs twisted up to within one-half of an inch of the connector

Which of the following connectors are used with fiber optic cables and include both cables in a single connector? (Select two) LC BNC MTRJ SC

LC MTRJ

What is the wiring closet in the basement or a ground floor that typically includes the demarcation point?

MDF (main distribution frame)

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? Why or why not?

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

Which device is used to terminate individual wires from a 25 pair or 100 pair cable using female RJ45 ports?

Patch panel

Which pins in an RJ45 connector are used to transmit data when used on a 100BaseT Ethernet network?

Pin 1 Pin 2

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?

Plenum rated cable

You are working with 25 pair wires and 66 blocks. You have pushed the wires onto the 66 block, but now you need to cut off the excess end of each wire. Which tool should you use?

Punch down tool

Which of the following connectors is used with Ethernet 1000BaseT networks? RJ11 ST BNC RJ45

RJ45

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

RJ48c

Which of the following connectors usually require polishing as part of the assembly process? (Select two) SC ST RJ45 F-type BNC

SC ST

Which connector is used with fiber optic cables and requires that you use a twisting motion to connect it?

ST (Set-and-Twist)

Which type of optical fiber is normally used to connect two buildings that are several kilometers apart?

Single-mode

Of the following cables, which offer the best protection against EMI? Cat 5e Cat 5 Single-mode fiber optic RG-6

Single-mode fiber optic

Which of the following is true about single-mode fiber optic network cabling? Single-mode fiber optic cabling is less expensive than multi-mode cabling. The central core is smaller than standard multi-mode fiber optic cabling core. Single-mode cabling supports shorter segment lengths than multi-mode fiber optic cabling. The central core is composed of braided plastic or glass fibers.

The central core is smaller than standard multi-mode fiber optic cabling core.

Which of the following are characteristics of an LC fiber optic connector? (Choose two) They are threaded. They use a housing and latch system similar to an RJ45 UTP connector. They can be used with either fiber optic or copper cabling. They are half the size of standard connectors. They use a one-piece bayonet connecting system.

They use a housing and latch system similar to an RJ45 UTP connector. They are half the size of standard connectors.

Which of the following are characteristics of an MTRJ fiber optic connector? (Select two) They are used with multi-fiber fiber optic ribbon cables They used a keyed bayonet They use metal guide pins to ensure accurate alignment They can be used with multi-mode fiber optic cables They must never be used with single-mode fiber-optic cables

They use metal guide pins to ensure accurate alignment They can be used with multi-mode fiber optic cables

What method would you use to create a crossover cable?

Use the T568A standard on one connector and the T568B standard on the other connector.

You have a network that occupies all three floors of a building. The WAN service provider has installed the line for the WAN service into the building in a wiring closet on the main floor. You have a wiring closet on the two remaining floors directly above the wiring closet on the main floor. What would you use to connect the wiring closets together?

Vertical cross connect

When would you typically use an RJ11 connector?

When connecting a phone to a phone line

You want to use the T56B standard for adding connectors to your Cat5 cable. Starting with pin 1, which order should you use for the wires within the connector?

White/orange, orange, white/green, blue, white/blue, green, white/brown, brown

Why might you use an RJ11 connector? You want to connect the 10BaseT network card in your computer to a switch. 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 test a network cable to see if there is a break in the line.
