129 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. A network card
B. An integrated print server
C. TCP/IP printing
D. AirPrint
130 A technician needs to perform maintenance on an inkjet’s dirty paper pickup rollers. What should she use to clean them?
A. Rubbing alcohol
B. Mild soap and water
C. A dry lint-free cloth
D. Compressed air
131 During which step in the laser printer imaging process is toner attracted to the imaging drum?
A. Exposing
B. Transferring
C. Fusing
D. Developing
132 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?
A. 500GB, 7200 rpm
B. 750GB, 5400 rpm
C. 750GB, 10,000 rpm
D. 1TB, 7200 rpm
133 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?
A. TPM
B. LoJack
C. Secure Boot
D. Drive Encryption
134 Identify the white connector on the section of motherboard shown here.
A. RAM
B. PATA
C. miniPCI
D. ATX
135 You need to purchase RAM for a computer. Which factor determines the speed of memory you should purchase?
A. CPU speed
B. FSB speed
C. BSB speed
D. ECC speed
136 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 rates?
A. Read/write head size
B. Connector size
C. Spin rate
D. Platter size
137 Three of these four motherboard form factors can be mounted in the same style of case. Which ones are they? (Choose three.)
A. ATX
B. MicroATX
C. Mini-ITX
D. Nano-ITX
D. Laser printers incorporate a fuser assembly, which uses two rollers that apply pressure and heat to fuse the plastic toner particles to the paper.
A. During the charging step, the charging corona uses a high voltage to apply a strong, uniform negative charge (around –600VDC) to the surface of the imaging drum.
A. 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.
D. Carriage motors are components in inkjet printers. Laser printer components include a fuser assembly, imaging drum, transfer belt, transfer roller, pickup roller, separator pads, and a duplexing assembly.
A. Laser printer uses various high-voltage biases inside the case, and high voltages can create ozone.
D. 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 device will have a dial or buttons to allow you to switch between systems.
B. 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.
B. 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.
D. 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 (–100VDC) as opposed to unexposed areas of the drum and the developing roller (which the toner is stuck to), which each have a charge of –600VDC.
C. 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.
B. 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.
D. The white connector is a 20-pin ATX power connector. You will also see 24-pin versions, which have two rows of 12 pins each.
B. 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 1333MHz, you should install memory that is rated at 1333MHz.
C. 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.
A, B, C. 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.
