LGA1156 (Socket H)
LGA2011 (Socket R)
Socket AM3+
Socket FM2
LGA1156 (Socket H)
LGA2011 (Socket R)
Sockets that support Intel processors are currently named starting with the letters LGA, such as LGA1156 and LGA2011. Socket names that start with AM or FM will support AMD processors and not Intel processors
You are discussing data storage needs with a client who is a videographer and media producer. She needs to store dozens of large files and needs immediate access to them for editing. What is the most appropriate storage technology for her use?
NAS
HDD
SD
HDD
A standard hard disk drive (HDD) will provide her with the highest capacity of the four options and also give her immediate access. Network attached storage (NAS) speaks to its connection and availability, not capacity. If the client required file sharing as well, then using a NAS would be the proper choice. Secure Digital (SD) is a memory card format and does not offer the capacity or immediacy she needs. BD-R is a Blu-ray Disc format. It has good storage capabilities, but not the immediacy for editing
You have a client that wants to build a high-end custom home theatre PC. Which two components will you suggest he install in the computer? (Choose two)
Sound card with surround sound
High-end cooling
Video card with HDMI outputs
Multicore processor
Sound card with surround sound
Video card with HDMI outputs
A home theater PC (HTPC) needs to maximize the audio and video experience. It won’t do a lot of processing or data management, so an upgraded processor or RAM is unneeded. Install a great sound card, a video card with multiple HDMI outputs, and a TV tuner card. (HDMI is capable of supporting 7.1 surround sound, so you may choose to buy one expansion card capable of handling both functions.) Some HTPCs come in a compact form factor, which is just a small case
You are searching for a new monitor on the internet and find a used digital LCD monitor for sale. What are the two most likely types of connector you will find on this monitor? (Choose two)
Composite
DVI-D
HDMI
VGA
DVI-D
HDMI
Digital monitors will have a digital interface, such as DVI-D, HDMI, or miniHDMI . Composite connectors are rarely used on monitors, and VGA is analog, not digital
A technician needs to purchase a new laptop for a manager. The manager has had several laptops fail and wants her new one to have as few components as possible to reduce the risk of failure. Which type of light source technology does not require an inverter and therefore is a better choice?
OLED
Plasma
LED
LED
There is no need for laptops with LED displays to convert the DC power coming into the laptop to the AC needed to power traditional fluorescent backlights because LEDs operate on DC power just like the rest of the laptop. Therefore, systems with LED backlights have no inverter board
Which of the following are typical formats supported by virtual printing? (Choose three)
Print to PDF
Print to XPS
Print to DOC
Print to image
Print to PDF
Print to XPS
Print to image
The four virtual printing options are print to file, print to PDF, print to XPS, and print to image
A bidirectional PCIe 1.1 x1 link provides how much data throughput?
250 MBps
500 MBps
2 GBps
500 MBps
There are four major versions of PCIe currently specified: 1.x, 2.x, 3.0, and 4.0. For the four versions, a single omnidirectional lane operates at a data rate of 250 MBps, 500 MBps, approximately 1 GBps, and roughly 2 GBps, respectively. A bidirectional slot doubles the data rate
Which component in a laser printer is responsible for heating up and melting the toner into the paper to create a permanent image?
Transfer corona assembly
Exit assembly
Fuser assembly
Fuser assembly
Laser printers incorporate a fuser assembly, which uses two rollers that apply pressure and heat to fuse the plastic toner particles to the paper
During which step in the laser printer printing process does a wire or roller apply a strong, uniform negative charge to the surface of the imaging drum?
Charging
Exposing
Transferring
Charging
During the charging step, the charging corona uses a high voltage to apply a strong, uniform negative charge (around –600 VDC) to the surface of the imaging drum
You are installing two new RAM modules into a single channel of a dual-channel motherboard. Which of the following is true?
Both RAM modules need to have the same parameters
The RAM modules can be different sizes but must be the same speed
The RAM modules can be different speeds but must be the same sizes
Both RAM modules need to have the same parameters
When installing dual-channel RAM, be sure that the RAM modules both have the same parameters. In some cases, you might even need to make sure they come from the same manufacturer
Which of the following printer components is not found in a laser printer?
Fusser assembly
Transfer roller
Carriage motor
Carriage motor
Carriage motors are components in ink-jet printers. Laser printer components include a fuser assembly, imaging drum, transfer belt, transfer roller, pickup roller, separator pads, and a duplexing assembly
What type of common printer can potentially release harmful ozone into the atmosphere and therefore may contain an ozone filter?
Laser
Thermal
Impact
Laser
A laser printer uses various high-voltage biases inside the case, and high voltages can create ozone
There are four servers in your server closet. You need to access each of them, but not at the same time. Which device will allow you to share one set of input and output devices for all four servers?
Touch screen
Docking station
KVM switch
KVM switch
The purpose of a KVM switch is to allow you to have multiple systems attached to the same keyboard, monitor, and mouse. You can use these three devices with only one system at a time, and the KVM switch will have a dial or buttons to allow you to switch between systems
A user on your network has an older laser printer with no Ethernet connection. It’s connected to his computer with a parallel cable. He has shared it on the network for others to use. Now, he wants no part of the printer, but others still need to use it on the network. What would be the best upgrade to install in this printer to allow others to send print jobs to it directly over the network?
A network card
An integrated print server
TCP/IP printing
An integrated print server
It sounds like this printer needs to manage its own print jobs; therefore, it probably needs to be its own print server. Installing an integrated print server with a network connection will probably do the trick
A technician needs to perform maintenance on an ink-jet’s dirty paper pickup rollers. What should she use to clean them?
Rubbing alcohol
Mild soap and water
Compressed air
Mild soap and water
Clean pickup rollers (and other rubber rollers) with mild soap and water and not alcohol. Alcohol can dry out the rollers, making them brittle and ineffective. A dry cloth will not remove the dirt or debris, and compressed air would just blow the debris into other internal printer components
During which step in the laser printing process is toner attracted to the imaging drum?
Exposing
Fusing
Developing
Developing
During the developing step, toner is attracted to areas of the drum where an image has been written by the laser. Those areas have a slight negative charge (–100 VDC) as opposed to unexposed areas of the drum and the developing roller (to which the toner is stuck), which each have a charge of –600 VDC
You are installing and configuring a magnetic hard drive and have several models to choose from. Which hard drive is most likely to have the highest data throughput rates?
500 GB, 7200 rpm
750 GB, 5400 rpm
750 GB, 10000 rpm
750 GB, 10000 rpm
The primary factor in determining data throughput for a magnetic hard drive is the spin rate. Higher spin rates will result in faster data reads and writes and increase data throughput
What is the name of the software package, typically enabled in the BIOS, that allows you to track the location of a stolen laptop or remotely lock it so it’s inaccessible?
TPM
LoJack
Secure Boot
LoJack
LoJack, made by Absolute Software, allows you to remotely lock a computer if it has been stolen or compromised. It will also allow security teams to locate stolen laptops
You need to purchase RAM for a computer. Which factor determines the speed of memory you should purchase?
CPU speed
FSB speed
BSB speed
FSB speed
Motherboards support memory based on the speed of the frontside bus (or the CPU’s QPI) and the memory’s form factor. For example, if the motherboard’s FSB is rated at a maximum speed of 1333 MHz, you should install memory that is rated at 1333 MHz
Your manager tells you to buy a high-capacity magnetic hard drive with the highest data transfer rate possible. Which hard drive parameter do manufacturers modify to increase hard drive data transfer?
Connector size
Spin rate
Platter size
Spin rate
To make information available to the rest of the computer more quickly, hard drive manufacturers increase the speed at which the hard drive platters spin
Three of these four motherboard form factors can be mounted in the same style of case. Which ones are they? (Choose three)
ATX
MicroATX
Mini-ITX
Nano-ITX
ATX
MicroATX
Mini-ITX
The ATX, MicroATX, and mini-ITX motherboard form factors can all be mounted inside a standard ATX case. The mini-ITX will have only three of the four mounting holes line up with the case, but the rear interfaces are placed in the same location as those on ATX motherboards
The security analyst recommends turning off hard drive write caching. despite the risk of data loss from a sudden power loss. What might be likely rationale for available hard drive caching?
Less power used
Data privacy
Quieter drive noise
Data privacy
Likely the security analyst’s recommendation is focused on the data privacy aspect of disabling hard drive caching, which could possibly be accessed through exploitation
Users complain print jobs are appearing very dim. What would be the likely action to try on an inkjet printer? (Choose two)
Clear jams
Replace cartridges
Clean heads (printer heads)
Replace paper
Replace cartridges
Clean heads (printer heads)
Printer heads can get clogged which causes poor quality, dim or no printing. And the cartridge may be near empty or performing badly. Clearing a jam is the right action when paper does not eject or partially ejects; likely a paper-crunching sound accompanies the issue. No paper coming out can also be a sign to replace or refill paper in the paper tray
