DLT
DAT
LTO
LTO
Linear Tape-Open is the newest and highest-capacity tape storage technology. LTO 7, released in 2015, has an uncompressed capacity of 6 TB per tape. LTO 6 had an uncompressed capacity of 2.5 TB. QIC tapes can often store around 1 GB. DLT can store up to 800 GB, and DAT can store up to 300 GB
A client wants you to upgrade his desktop computer to have two video cards. You want to be sure that his computer can support the extra adapter. What type of open internal expansion slot should you look for?
PCIe
VGA
DVI
PCIe
Most internal video adapters today are PCIe cards. You might still find older PCI or AGP cards on the market as well. ISA is a legacy expansion slot type not used today. VGA and DVI are types of monitor connectors but not expansion slot types
Which step immediately follows the fusing step in the laser printer imaging process?
Processing
Exposing
Cleaning
Cleaning
The order of steps is processing, charging, exposing, developing, transferring, fusing, and cleaning
Which of the following are services created by Apple to allow for the automatic discovery of printers on local networks? (Choose two)
Bonjour
AirPrint
TCP printing

Apple created Bonjour and AirPrint
After installing a new print cartridge in an Ink-jet printer, what process must be run before printing to the device?
Degaussing
Rasterizing
Calibration
Calibration
Before you print to an ink-jet printer, you must ensure that the device is calibrated. Calibration is the process by which a device is brought within functional specifications. For example, ink-jet printers need their print heads aligned so that they print evenly and don’t print funny-looking letters and unevenly spaced lines
The most common RAM slots used in desktop and laptop computers, respectively, are what?
DIMM and Mini-DIMM
DIMM and SODIMM
Mini-DIMM and SODIMM
DIMM and SODIMM
Desktop computers use dual inline memory modules (DIMMs), and laptops most commonly use small outline DIMMs (SODIMMs). Another potential laptop memory form factor is the Micro-DIMM
Which type of printing technology uses a heating element to make images on waxy paper?
Laser
Thermal
Solid ink
Thermal
Thermal printers use a heating element. It heats up spots on special waxy, heat-sensitive paper to form the image
You have a laser printer that is displaying the message “Perform user maintenance.” What should you do to resolve this situation?
Apply a maintenance kit and clear the message
Turn the printer off and on again to clear the message
Re[ace the toner cartridge and clear the message
Apply a maintenance kit and clear the message
When a laser printer requests maintenance, it’s because it has reached a certain page count. Apply a proper maintenance kit (one recommended by the manufacturer) and then clear the service message
PCI-X expansion slots are compatible with what other adapters?
33 MHz PCI
66 MHz PCI
133 MHz PCI
66 MHz PCI
PCI-X slots are physically compatible with PCI adapters. Because all PCI-X slots support the 66 MHz minimum clock rate, PCI-X slots are compatible with 66 MHz PCI adapters
A user wants to create the ultimate gaming PC. Which of the following peripherals would be most appropriate for this type of system?
Chip reader
Joystick
Smart TV
Joystick
There are dozens of peripherals on the computer market. Joysticks are used primarily to play video games. Chip readers will scan EMV chips, like on a credit card. Magnetic readers are for reading credit cards’ magnetic stripes on the back. Smart TVs play television. Camcorders are another type of peripheral, used to record video
You need to create several UTP cables from a roll of bulk cable. Your company uses the T568B standard. What is the correct order for wires in the connectors?
White/orange, orange, white/green, blue, white/blue, green, white/brown, brown
White/orange, orange, white/green, green, white/blue, blue, white/brown, brown
White/orange, green, white/green, blue, white/blue, orange, white/brown, brown
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
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
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
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
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
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
MMF
CAT7
Multimode fiber (MMF) and UTP CAT6 and newer support 10 Gbps transmission speeds
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
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
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
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
Which type of coaxial cable connector locks by twisting the connector one-quarter turn?
BNC
SC
ST
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
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
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
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
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
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
CAT5
CAT5 UTP can transmit data at speeds up to 100 Mbps, for a distance of 100 meters
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
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
What is used in an 3d printer which allows it to print or create three dimensional objects?
Compressed air
Plastic filament
Plastic ink
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
