141 You have been asked to assemble 20 new desktop PCs for a client. When you look at the first motherboard, you see four memory slots. The one closest to the CPU is colored blue. Then in order they are white, blue, and white. Which of the following statements are true? (Choose two.)
A. This is a quad-channel motherboard.
B. This is a dual-channel motherboard.
C. For optimal performance, you should install RAM modules into the two slots closest to the CPU.
D. For optimal performance, you should install RAM modules into the two blue slots.
142 One of your Windows 8 users has a file they want to print as a .pdf file, but the application they are using does not support printing to .pdf. What would be their best option?
A. There is no way to print to .pdf if the application does not support it.
B. Use the Windows 8 native feature to print to .pdf.
C. Install a third-party app that installs support for printing to .pdf.
D. Use the Windows 8 native feature to print to .xps and then convert the .xps file into .pdf.
143 You have a computer running Windows 8. Every time you boot, the computer insists on trying to boot from the DVD-ROM drive. Where can you change the setting to have the system boot to the hard drive first?
A. BIOS
B. Windows Configuration
C. System Manager
D. Device Manager
144 Which of the following types of connectors are generally found on the front or top panel of the computer? (Choose two.)
A. Hard drive
B. Optical disk
C. Power button
D. USB
145 Your manager is excited because he just purchased a fast USB 3.0 external hard drive for his work team. He wants to set it in the middle of the cubicles and let everyone have access to it. Some of the cubicles are about 15 feet away from each other. What is the recommended maximum cable length for this type of device?
A. 3 meters
B. 5 meters
C. 10 meters
D. 15 meters
146 A technician has just installed a duplexer on a laser printer. The duplexer was sold by the manufacturer and is compatible with the printer. However, the printer properties will not let anyone choose to print on both sides of the paper. What might resolve the issue?
A. Removing and reinstalling the duplexer
B. Turning the printer off and back on
C. Upgrading the printer’s firmware
D. Stopping and restarting the spooler service
147 You have a desktop computer with three PCI expansion slots. What will happen when you mix cards of different speeds on the same motherboard?
A. The cards will operate at their original speeds.
B. None of the cards will function.
C. The cards will all operate at the faster speed.
D. The cards will all operate at the slower
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.
C. If memory supports ECC, check bits are generated and stored with the data. If one of the eight memory bits is in error, ECC can correct the error.
A, D. USB flash drives and SD cards are hot swappable. (In the case of USB, be sure that the flash drive does not contain key file system files needed for the computer to run!) Hybrid SSDs might or might not be hot swappable and are larger than USB and SD drives. PATA devices are generally not hot swappable.
C. This SLI-ready motherboard has three PCIe x16 slots (every other slot, starting with the top one), one PCIe x1 slot (second slot from the top), and two PCI slots (first and third slots from the bottom). Notice the latch and tab that secures the x16 adapters in place by their hooks.
B, D. Dual-channel motherboards have two banks of two RAM slots. They are color coded such that the two slots of the same color belong to the same channel. Sometimes the like-colored slots are adjacent to each other, but other times they alternate. For optimal performance, fill one channel completely.
C. Install an application that provides support for printing to .pdf. Then, when the user opens the print window, they can choose the .pdf option.
A. The boot sequence of a computer is changed in the BIOS settings.
C, D. Typical front- or top-panel connectors include USB, audio, power button, power light, drive activity lights, and the reset button. Hard drives and optical disk players generally connect to the motherboard.
A. USB 3.0 has a cable length limitation of 3 meters. USB 2.0 cables can be up to 5 meters in length.
C. Printer firmware upgrades can offer newer features that are not available on previous versions.
D. PCI is a shared-bus topology, so mixing 33MHz and 66MHz adapters in a 66MHz system will slow all adapters to 33MHz.
