Storage Devices
This storage device consists of several aluminum platters. All read/write heads are attached to a single access arm to prevent them from moving independently. Each platter has circular tracks that cut through all the platters.
Hard disk drive
Which of the following is the most common disk interface used for optical drives on home and office computers?
SATA, Sound Card, Parallel Port, SCSI
SATA
Which optical media was first developed to store digital music and later, it was adapted to store digital computer data?
Compact Disc (CD)
What is the minimum number of hard disks you can use to configure RAID 5?
Three
What do you call a logical division of a storage device associated with a hard drive.
Partition
True or false:
Windows automatically assigns an available drive letter when you connect an external hard drive.
TRUE
Check Disk detects disk integrity errors and fixes them.
Name the disk integrity error described as follows:
A series of used clusters on the hard disk drive that are not associated with a specific file.
Lost clusters
This type of storage device is designed to allow access to non-volatile storage media through a PCI express (PCIe) bus
Non-Volatile Memory Express
(NVMe)
Which devices can NOT be connected using SATA
Hard disk drives, Optical drives, Floppy drives, Optical drives
Floppy drives
Was originally developed for high definition video (and expanded content on movie discs), but can also be used for data storage.
Blu-ray Disc (BD)
Which RAID configuration uses striping with parity for fault tolerance?
RAID 5
What do you call a container in a file system used to logically sort and organize data?
Directory
When you configure Storage Spaces in Windows, you can include information redundancy with a feature called data resiliency.
Which type of data resiliency requires at least three storage devices.
Parity
Check Disk detects disk integrity errors and fixes them.
Name the disk integrity error described as follows:
When two files claim the same cluster.
Cross-linked file
Which of the following is a magnetic storage device?
- Solid-state drive
- Flash device
- DVD
- Hard disk
Hard disk
Which SATA standard is meant to replace eSATA?
eSATAp
Which Blu-ray standard defines rewritable discs?
BD-RE
Which RAID method would you use if you want to use a RAID 0 array for the operating system using SATA disks and a special controller card that includes a RAID processor.
Hardware
What do you call a single accessible storage area within a file system.
Volume
When you configure Storage Spaces in Windows, you can include information redundancy with a feature called data resiliency.
Which type of data resiliency requires at least five storage devices.
Three-way mirror
Check Disk detects disk integrity errors and fixes them.
Name the disk integrity error described as follows:
A portion of the hard disk that cannot be used.
Bad sector
A device that is faster than other comparable devices. It has no moving parts and lasts longer than other storage devices.
Solid-state drive (SSD)
Which generation of SATA storage devices supports up to 6-Gbps data transfer rates and addresses solid-state drives?
SATA3
What is a disadvantage of using a DVD-R DL (Dual Layer) disc over an ordinary DVD?
- A DVD-R DL has slower write speeds.
- A DVD-R DL has to skip across the disc to find the next track.
- A DVD-R DL is not backwards-compatible with a regular DVD player.
- A DVD-R DL stores less data.
A DVD-R DL has slower write speeds.
You are building a new computer that will contain two hard disks.Which RAID implementation would you configure to provide increased performance?
RAID 0
This disk type is supported by all operating systems.
Basic disks
When you configure Storage Spaces in Windows, you can include information redundancy with a feature called data resiliency.
Which type of data resiliency does not provide protection from a single storage device failure
Simple
You would use this command line utility to correct cross-linked clusters within the file system on a Windows workstation.
chkdsk
An older electronic interface allows communication between a motherboard's data paths (or bus) and a computer's hard disks.
Integrated Drive Electronics
(IDE)
Which SATA standard introduced the hot-pluggable support standard?
SATA2
The second generation of SATA devices support up to 3 Gbps (3000 MBps). SATA2 includes the following enhancements:
How much data can a double-layer Blu-ray disc hold?
a double-layer disc holds up to 50 GB.
You are using Disk 1 and Disk 2 on your Windows 11 workstation to create a RAID 0 striped volume. Disk 1 stores 500 GB, and Disk 2 stores 1.5 TB.
What will be the total amount of available disk space allocated for the striped volume?
1 TB
You have just saved a word processing document on your hard drive. However, your Windows system suddenly crashes because of a memory usage problem.
When you reboot your computer and open the document, the document seems to be in good shape without any issues.
Which of the following partition types might have helped contribute to the recovery of your document?
UEFI, GPT, MBR, BIOS
GPT
You have a thin-provisioned storage space that suddenly unmounts.
What is the MOST likely cause of this problem?
- One of the disks in the storage space pool has crashed.
- The storage space has run out of disk space.
- A new storage device has been added to the pool.
The storage space has run out of disk space.
This command should be run on a Linux system to find out how much disk space is being used on each of the file systems?
df -h
