Which of these speeds matches the bandwidth seen on a gigabit Ethernet link? A. 100 MB/s B. 1000 Mb/s C. 1000 MB/s D. 100 Mb/s

1000 Mb/s This is a two part question, because there's both a (relatively easy) conversion to complete, and then you have to know your abbreviations. For the first part of the question, you'll need to know that a gigabit Ethernet connection runs at 1 gigabit per second, which is also 1000 megabits per second. For the second part of the question, it's important to understand the importance of a lowercase "b" and an uppercase "B." When abbreviating speeds, a lowercase "b" represents bits, and an uppercase "B" represents bytes. Therefore, Mb/s is an abbreviation for megabits per second, and MB/s is an abbreviation for megabytes per second. With all of these details, the answer should be relatively clear; 1 gigabit Ethernet transports data at an equivalent speed of 1000 Mb/s

The Power On Self Test process performs a series of hardware diagnostics before the operating system loads. Which of these problems would NOT be found during POST? A. A missing CPU heat sink B. A faulty video card C. A bad RAM module D. A bad hard drive

A missing CPU heat sink A heat sink's job is to redistribute the heat from a hot CPU into the heat sink, where it's then cooled by the constant airflow through the computer case. If the heat sink is missing or isn't connected well, you won't know there's a problem until the CPU heats up. Bad video cards can be a problem, since no video means you have no visual feedback on the boot process. For bad video cards, the BIOS often beeps to inform you of the bad video. Since nearly everything on your computer uses the RAM, those chips are given a good once-over during the POST process. When a hard drive goes missing, it's an easy thing to identify. If a drive is missing or won't respond, the BIOS will complain.

Which of these options would be the most accurate description of inkjet printing? A. Low cost per page B. Quiet C. High-speed printing D. Good for multiple copies

Quiet An inkjet printer is great for work areas because of its relatively low noise compared to other printing methods. Because the process of putting the ink onto the paper is nearly silent, the only sounds that usually come from an inkjet printers are those of the mechanics of the print head moving back and forth across the paper. Inkjet printer ink is notoriously expensive, making inkjet printers relatively expensive when compared to other common printer types such as laser printers. An inkjet printer can produce sharp copies, but the process of spraying a sheet of paper with ink can be time consuming. Large print jobs are usually best left to high-speed laser printers. Impact printers such as dot-matrix printers can handle multiple copies in one pass, but inkjet printers don't have a way to enjoy the same efficiencies. If you want more than one copy on an inkjet printer, you'll need to print

Which of these RAID types splits data evenly across two or more disks, but does not provide any data redundancy? A. RAID 0 B. RAID 1 C. RAID 5 D. RAID 1+0

You need to design a drive array that will continue to operate if any drive fails. Which RAID types fit this requirement? Pick two. A. RAID 0 B. RAID 1 C. RAID 5 D. RAID 1+1

RAID 1 and C. RAID 5 RAID 0, or striping, provides high performance but a single drive failure breaks the array. RAID 1 and RAID 5 both continue to operate, even if a single drive fails

Which of these RAID types create an exact duplicate of data across physical drives? Pick two. A. RAID 0 B. RAID 1 C. RAID 2 D. RAID 5 E. RAID 1+0

RAID 1 and E. RAID 1+0 RAID 1, or mirroring, is an exact duplicate of all data across multiple physical drives. RAID 1+0 combines mirroring and striping to create a RAID 0 striped set of data that is duplicated across multiple RAID 1 mirrored drives.

Which of these RAID types provide redundancy when a drive fails? Pick two. A. RAID 0 B. RAID 1 C. RAID 5 D. RAID 11

RAID 1 and RAID 5 RAID 1 (mirroring) and RAID 5 (striping with parity) both provide redundancy if you lose a hard drive. RAID 0 (striping) provides high performance, but there's no redundancy if a drive crashes.

You've received a message in your error log that a drive in your RAID 1 array is faulty. What's the best way to rebuild this RAID 1 array? A. RAID 1 arrays are redundant, so you simply need to replace the bad drive B. RAID 1 arrays are not redundant, so you'll need to replace the drive and restore from a backup C. RAID 1 arrays are redundant, but will still require restoration from backup after the drive is replaced D. RAID 1 arrays cannot be rebuilt

RAID 1 arrays are redundant, so you simply need to replace the bad drive RAID 1 is a mirrored array, where data is completely duplicated across physical hard drives. If you lose a hard drive, the array is redundant and will continue to operate; usually without any loss of performance. I've personally identified bad hard drives in RAID 1 arrays that failed months prior, without anyone realizing there was a problem. Rebuilding the drive array is relatively easy. If the drive array supports hot swapping, you don't even need to power down your computer during the drive replacement. The RAID array will recognize that a new drive has been added to the array and will duplicate the existing data to construct a new RAID 1 mirror

Which of the following requires a MINIMUM of four hard drives? A. RAID 0 B. RAID 1 C. RAID 5 D. RAID 10

RAID 10

If you had four identical drives, which of these RAID types would provide both redundancy and the most available storage space for your data? A. RAID 0 B. RAID 1 C. RAID 5 D. RAID 1 + 0

RAID 5 RAID 0 does not provide redundancy, and RAID 1 and 1+0 are mirroring data and therefore are effectively limiting available storage space by 50%. RAID 5 also provides redundancy, but it only uses the space of a single drive for the redundant parity data. With four drives, this means that RAID 5 would provide data storage that was equal to three of the four disks, or 75% of the total disk space.

Your laptop AC adapter states that it is "auto switching." What does this mean? A. The power supply can be used in many different countries B. The power supply can be used on many different laptop models C. The power supply can be used with many different operating systems D. The power supply can be used on both laptops and docking stations

The power supply can be used in many different countries An auto switching power supply can support multiple voltages without flipping a physical "switch." Most laptop auto-switching power supplies can support both 110 volts and 220 volts, which covers the power requirements in most countries. All you need is a power plug adapter, and you can take your laptop anywhere!

The power supply of your computer lists these specifications on the label: Input: 100-120V ~ / 4.0A 220- 240V ~ / 2.0A What does this information mean? A. The power supply can support both 100-120V DC and 220-240V DC power sources. B. The power supply can support both 100-120V AC and 220-240V AC power sources. C. The power supply uses 4 amps of power when using a 220-240V AC power source. D. The power supply uses 2 amps of power when using a 110-120V DC power source

The power supply can support both 100-120V AC and 220-240V AC power sources. Many computer power supplies are switched-mode power supplies that can support multiple voltage inputs. On these specifications, both 100 through 120 volt and 220 through 240 volt power sources are supported. Some power supplies can automatically switch between these input voltages and others have a physical switch on the outside of the power supply. You would normally switch the power input value based on your country's power specifications. The squiggly tilde (~) designates an alternating current (AC). If the specifications showed a solid line above a dashed line, it would be referencing direct current (DC). The amperage used by the power supply will differ when using different voltages, so the input amperage is listed as different values at 100-120 volts versus 220-240 volts.
