Q

You need to install a new hard drive into a desktop computer, which of the following is NOT one of the three major components of a hard disk drive system?

Drive Interface

Disk Controller

Hard Disk

Q

You’re installing a new hard drive and want to know if the operating system will be able to support it. What is the largest NTFS volume size supported, assuming a 64 KB cluster size as maximum?

1 TB

2 TB

128 TB

256 TB

A

256 TB. A fixed number of clusters is supported by operating system, leading to a corresponding maximum volume size. If the maximum NTFS cluster size of 64 KB is used, NTFS can support a single-volume size of 64 KB less than 256 TB. When a cluster size of one sector is, 512 bytes (1/2 KB), is used, the maximum volume size reduces to 2 TB. Because of this math, 1 TB and 128 TB are incorrect.

Q

A customer is looking for a desktop drive technology that saves money over SSD but offers performance increases over HDD’s and can be used to house the operating system. Which of the following is the best to recommend?

Dual-drive technology.

SSHD

NVMe

Magnettic-only drive

A

SSHD (Solid State Hard Drive) incorporates the features of both conventional magnetic-only hard drives and solid-state drives. As a result, the performance of an SSHD exceeds that of a hard drive but costs less than an equivalent sized SSD. Dual-drive option still requires the purchase of a full sized SSD. Adding the cost of a HDD, the dual-drive option does not satisfy the requirement of an affordable technology. NVMe is a form of solid-state drive and does not save money.

Q

Which of the following best describes the concept of hot-swappable devices?

Power does not need to be turned off before the device is inserted or removed

The device can be removed with power applied after it is properly stopped in the operating system

Care must be taken when swapping the device as it can be hot to touch.

The device can swapped while still hot, immediately after powering down the system.

A

Hot swappable devices can be removed while the power to the system is still on. Warm-swappable devices need to be stopped in the operating system before being removed. The term has nothing to do with the temperature of the device.

Q

Of the following voltage pairings, which one accurately describes the input/output of power supplies and AC adapters?

AC in, AC out

DC in, DC out

AC in, DC out

DC in, AC out

A

Ac in, DC out. Power supplies and AC adatpers use standard wall sockets for an input of AC volatge, which is then converted to DC voltages required by the conponents they supply.

Q

You are installing a new power supply in a desktop computer. Which of the following statements about power supplies is true?

You must ensure that the voltage selector switch on the back of the power supply is switched to the lower setting if you’re in Europe

SATA hard drives most often use the same yepr of power connector that PATA hard drives use

Power supplies supply power to ATX-based motherbaords with connectors known commonly as P8 andP9

Power supplies convert AC input to DC output

A

Power supplies convert AC input to DC output. Europe requires the voltage setting to be on the highest setting. SATA drives most often use a specific power connector that is not compatible with Molex connectors used by PATA drives. Legacy AT-based motherboards used P8/P9 connectors; ATX motherboards have newer 20-24-pin single power connectors.

Q

You have been sked to install a new hard drive for a customer. Which of the fallowing is NOT a consideration when installing an internal storage device?

You should match the form factor of the drive or adapt it to an available drive bay or slot.

You should secure the drive with at least two screws on one side but preferably two on each side.

Due to the high revolution at which modern Hard drives spin, you must secure an external power source because the internal power doesn’t have to capacity

You need to be sure that the routing of the drive’s data cable, if applicable, doesn’t obstruct the engineered flow of air across the components.

A

Today’s hard drives, regardless of their rpm, have standard internal power connections. The other options are all considerations when installing an internal drive.

Q

Due to government regulations, a client wants to preserve data for a long period of time. What kind of media is most commonly used when large amounts of data need to be archived on a regular basis?

Tape

Optical Disc

External Hard Drive

Network Share

A

Tape. Althought inefficient as an interactive medium, sequential tape-based storage continues to be developed in increasing capacities. Tape continues to be a good choice for frequently backing up large amounts of data for redundancy and archival purposes. Optical discs don’t have the same capacity, and neither do external hard drives. The cloud could be an option, but that is different from a network share.

Q

When installing multiple add-on cards of the same type, which of the cards might you have to bridge together to function as a single unit?

Video

Sound

USB

eSATA

A

A. PCIe video cards may be bridged together, enabling two cards to function as one system. Sound cards and I/O expansion cards such as USB and eSATA cards do not have bridging capabilities.

Q

You are purchasing a new video card in a desktop comptuer. For thebest performamce which type of video card should get?

PCI x 16

PCI x 128

AGP

PCIe x 128

PCIe x 16

A

PCIe 16. There is no PCI x 16 and PCI x 128. There is also no PCIe x 128. AGP is an older, obsolete, expansion card.

Q

You are choosing a flash standard for a client. They want the smallest flash cards possible. Which standard should you recommend?

SD

Compact Flash

microSD

miniSD

xD

A

MicroSD, at 15mm x 11mm. Micro does give it away. SD cards are 32mm x 24mm. CompactFlask ards are the largest, at 36mm x 43mm. MiniSD cards measure 21.5mm x 20mm and xD cards are 20mm x 25mm.

17
Q

Your goal is to build the fastest computer possible. Which of the following hard drive technologies should you choose for the fastest read performance?

M.2 PCIe

M.2 SATA

NVMe PCIe

NVMe SATA

A

NVMe PCIe. M.2 and NVMe are both very fast but NVMeis sloghtly faster. SATA is limited to 600 MBps where as PCIe isn’t. A NVMe PCIe card can sustain data transfer rates of around 3500 MBps

18
Q

You have been asked to configure a RAID 5 system for a client. Which of the following statements about RAID 5 is true?

It provides fault tolerance but no performance imporvement.

It provides performance improvements but no fault tolerance.

If multiple drives in the array fail, the data can be saved provided that one drive is still operational.

It requires at least three drives to implement.

A

RAID 5 requires a minimum of three hard drives to implement. If one drive fails the data is fine and the system can still function, albeit slowly. If more than one drive fails the system will be inoperable. RAID 5 proves both fault tolerance and a performance improvement.

19
Q

You have a motherboard with integrated video, and the video fails. You install a video add-on card. Which of the following statements are the most accurate? (choose two)

The addon card will not fucntion properly because of the integrated video

The addon card will function if it is bridged to the integrated video chipset

The addon card will be detected automatically and function properly if it’s PCIe

For the card to work properly , you might need to disable the integrated video in the BIOS.

The addon card will work properly by using the integrated video driver

A

Most likely the addon card will detected automatically though drivers will need to be downloaded.

The intergated video may need to be disabled in the BIOS

20
Q

When replacing a power supply, which of the following tends to cary amoung power supplies and must be chosen properly to support ll the connected devices?

Wattage

Voltage

Amperage

Resistance

A

Power supplies are rated in watts. When you purchase a power supply you should make sure the devices in the computer do not require more wattage than the power supply offers.
