A computer's SATA RAID array is missing, and the onboard clock is slow. Which of the following steps should be taken to restore the system? (Choose all that apply.) a. Replace CMOS battery. b. Enable SATA RAID. c. Reset clock. d. Format hard disks.

A, B, C. The slow clock is a symptom of a dead or dying CMOS battery. When system settings are lost, the RAID settings in the BIOS may be lost. However, the hard disks' contents are not affected. (a, b

Select the correct statement about SATA drives. a. The slowest SATA drive runs at 1.0Gbps. b. SATA hard disks must use locking cables. c. SATA 3Gbps drives are compatible with slower SATA ports. d. SATA is used only by hard disk drives.

A. (?c) SATA 3Gbps drives can be used with any speed of SATA port but might need to be jumpered to reduce performance to avoid data loss when used with 1.5Gbps ports (the slowest SATA speed). SATA is also used by DVD and Blu-ray drives.

Which of the following media types are used by a Super Multi DVD drive? (Select all that apply.) a. Blu-ray (BD) b. DVD + RW c. DVD-R DL d. LS-240 SuperDisk

B, D. (?B, C) Super Multi DVD drives can use any type of DVD recordable or rewritable media as well as CD. LS-240 SuperDisk is an obsolete floppy disk type, and BD (Blu-ray) is a higher-capacity optical media than DVD. (a, b, c

Which of the following interfaces are typically used for internal hard disks on desktop PCs? (Select all that apply.) a. USB 3.0 b. PATA c. eSATA d. SATA

B, D. PATA and SATA are the leading internal drive interfaces. USB 3.0 is a standard for external storage and other types of devices, while eSATA is an external variation of SATA.

Your client has a Windows XP computer with a Super Multi DVD drive. However, the user reports an inability to burn DVDs but can read DVD data discs. Which of the following could be accurate statements? a. DVD laser has failed b. User needs to use third-party software to burn DVDs. c. Drive not designed to burn DVDs. d. User should install Windows Movie Maker to get better DVD support.

B. Windows XP can burn CDs, but not DVDs, in a DVD drive. If the DVD laser had failed, the drive could not read DVDs. A Super Multi DVD drive will burn DVDs. Windows Movie Maker for XP does not include DVD support.

Your client wants to use an external hard disk to perform backups. Which of the following interfaces is the fastest? a. USB 2.0 b. FireWire 800 (IEEE 1394b) c. eSATA 1.5Gbps d. USB 3.0

D. USB 3.0 is the fastest (5Gbps) of the ports listed here. Note that some older backup programs don't support USB 3.0.

You are upgrading a system with a tape backup drive from Windows XP to Windows 7. To ensure that existing tapes can be read by Windows 7, what else do you need to install? a. Removable Storage Manager for Windows 7. b. New drive firmware. c. Configure backup program to run in Windows XP compatibility mode. d. Windows 7 drivers for the drive.

D. Windows 7 does not include Removable Storage Manager (RSM) and RSM is not available for Windows 7. The only way to use a tape drive under Windows 7 is to install Windows 7-compatible drivers or to create a Windows XP VM and use the drive inside the VM to read data.(c

You have installed an SSD in a new Windows 7 system, and its performance is no faster than the hard disk it replaced. Which of the following steps should you perform to improve performance? (Choose all that apply.) a. Configure SATA port for IDE mode. b. Install new drivers in Windows. c. Upgrade drive to newest firmware version. d. Use tweaking utility for SSD drives.

C, D. SSD drives don't require different drivers in Windows. IDE mode disables NCQ, TRIM, and other advanced features not supported by PATA drives. Firmware updates are essential to enabling SSD drives to run as fast as possible, and a tweaking utility for Windows helps ensure best performance.

You have used a bus-powered USB drive to make a backup copy of files you need to restore to a different system. When you plug the drive into a USB hub, it cannot be recognized. Which of the following is your best solution? a. Attach an AC adapter to the hub. b. Attach an AC adapter to the drive. c. Connect the drive directly to one of the USB ports d. Use a longer USB cable between the drive and the hub.

C. A USB root hub (USB port on the computer) has the best chance of success. A USB hub that is bus powered usually doesn't have an AC adapter. In some cases, a shorter USB cable can transmit enough power from a USB root hub or self-powered hub to enable a bus-powered drive to work.(a

You have just installed an eSATA hard disk on your system by using an eSATA/ SATA header cable. If you want to hot-swap the drive, which of the following configuration settings are needed in the system BIOS for the SATA port? a. Configure port for IDE mode. b. No changes needed in any event. c. Configure port for UDMA mode. d. Configure port for AHCI mode.

D. AHCI mode enables hot-swapping. IDE mode forces the drive to emulate PATA drives (which can't be hot-swapped). UDMA mode is used by PATA drives, not SATA drives.

Select the correct statement about PATA drives. a. PATA drives can use only 80-wire cables. b. PATA drives run at top speed when used with 40-wire cables. c. PATA UDMA133 drives are the only drives that require a 80-wire cable. d. PATA UDMA66 and faster drives require a 80-wire cable.

D. PATA drives can use either 40-wire or 80-wire cables, but performance on newer drives is reduced when a 40-wire cable is used. UDMA133 drives are the fastest of the three drive classes that require the 80-wire cable.

You need to install a RAID 1 array for a client. The client needs a minimum capacity of 500GB in the array and offers two available drives for possible use: 750GB and 1TB. Which of the following is the best solution? a. Use the 1TB drive and partition it into two drive letters to create the array. b. Can't be created with current drives; must purchase at least one additional hard disk with an 750GB or 1TB capacity. c. Partition both drives to have 500GB primary partitions, and use them in the array. d. Create a 750GB RAID 1 disk array using the hard disks.

D. You must have two physical hard disks to create a RAID array. You can use different sizes of drives, but the array is limited to the size of the smaller drive in those cases. You don't need to partition the drives before creating the array. (c
