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

The correct order for a T568B cable is white/orange, orange, white/green, blue, white/blue, green, white/brown, brown

Question 12

You are installing network cable that will support digital cable television signals. What type of cable should you install?

RG-6

RG-8

RG-59

Answer 12

RG-6

Cable television installations typically use either RG-6 or RG-59 cable. RG-6 is slightly thicker, can run longer distances, and supports digital signals. RG-59 is suited only for analog TV signals

Question 13

You need to replace faulty 250-foot section of RG-6 cable, but all you have available is RG-59. Which of the following statements is true?

The replacement cable will not work because RG-6 and RG-59 use different connectors

The replacement cable will not work because RG-6 and RG-59 use different impedance

The replacement cable should work

Answer 13

The replacement cable should work

RG-6 and RG-59 can, in many cases, be used interchangeably. RG-6 is a better choice because it supports digital signals and has a longer range (304 meters or 1000 feet). RG-59 can run up to 228 meters (750 feet). Both have impedance of 75 ohms, and both use BNC connectors or F-connectors

Question 14

You have been asked to design a new network that requires 10 Gbps transmission speeds. Which cable types will meet the minimum specifications? (Choose two)

MMF

CAT5

CAT5e

CAT7

Answer 14

MMF

CAT7

Multimode fiber (MMF) and UTP CAT6 and newer support 10 Gbps transmission speeds

Question 15

Which characteristic differentiates STP from UTP?

It uses RJ-45s connectors instead of RJ-45

It follows the T568A wiring standard

It has a layer of foil shielding

Answer 15

It has a layer of foil shielding

Shielded twisted pair (STP) cabling has a foil shield surrounding the wire pairs to decrease electrical interference. Some STP cables also shield individual wire pairs. Unshielded twisted pair (UTP) does not have the shielding. Both types use RJ-45 connectors, can follow the T568A wiring standard, and can be produced as plenum-rated cable that does not produce poisonous gas when burned

Question 16

While cleaning out a storage room, a technician finds several rolls of CAT5e network cable. He thinks that he might be able to use it to create replacement cables for his network. What is the maximum speed that this cable will support?

1 Gbps

10 Gbps

20 Gbps

Answer 16

1 Gbps

CAT5e cable can support speeds of 1 Gbps. CAT5 has a maximum of 100 Mbps. CAT6 and newer can support 10 Gbps, but no UTP cabling can currently support 20 Gbps

Question 17

Which type of coaxial cable connector locks by twisting the connector one-quarter turn?

BNC

SC

ST

Answer 17

BNC

The BNC connector locks by twisting one-quarter turn. F-connectors are threaded and screw into place. SC and ST connectors are for fiber-optic cable

Question 18

Your network uses UTP cabling. Which of the following types of network connections require the use of a crossover cable? (Choose two)

Computer to hub

Computer to switch

Computer to router

Switch to switch

Answer 18

Computer to router

Switch to switch

A crossover cable is one where the two devices being connected are similar, without using a hub or switch. The exception is when you are connecting a hub or switch with another hub or switch. If you are going to make a connection from hub to hub, switch to switch, router to router, hub to switch, or a computer directly to a router, you need a crossover cable. Otherwise, you need a regular patch cable. Lastly, if a networking device offers a medium dependent interface crossover (MDIX) port, then a straight-through cable can be used where a crossover cable would be correct

Question 19

You are replacing a connector at the end of coaxial cable. What type of connector is threaded and screws into place?

F-connector

BNC

SC

Answer 19

F-connector

F-connectors are threaded and screw into place. The BNC connector locks by twisting one-quarter turn. SC and ST connectors are for fiber-optic cable

Question 20

You are installing UTP network cabling. The network has a mixture of network cards, but the minimum required speed is 100 Mbps. What is the minimum grade of cable you can install to meet this requirement?

CAT3

CAT5

CAT5e

Answer 20

CAT5

CAT5 UTP can transmit data at speeds up to 100 Mbps, for a distance of 100 meters

Question 21

You have been asked to create a UTP crossover cable. Which pins need to be crossed over to make the cable work properly?

1 and 2, 3 and 6

1 and 3, 2 and 6

1 and 6, 2 and 3

Answer 21

1 and 3, 2 and 6

In a crossover cable, pin 1 to pin 3 and pin 2 to pin 6 are crossed on one side of the cable only. This is to get the “send” pins matched up with the “receive” pins on the other side and vice versa

Question 22

What is used in an 3d printer which allows it to print or create three dimensional objects?

Compressed air

Plastic filament

Plastic ink

Answer 22

Plastic filament

In a 3d printer, a plastic filament is pulled though it’s print head, a nozzle. This process contrasts to how ink is pushed through a paper printer’s print head
