GUID Partitioning Table (GPT)
A disk-partitioning method that supports volume sizes up to 18 exabytes.
just a bunch of disks (JBOD)
just a bunch of disks (JBOD)

local storage
Storage media with a direct and exclusive connection to the computer’s system board through a disk controller.
logical unit number (LUN)
logical unit number (LUN)
A logical reference point to a unit of storage that could refer to an entire array of disks, a single disk, or just a part of a disk.
Master Boot Record (MBR)
Master Boot Record (MBR)
A disk-partitioning method that supports volume sizes up to 2 TB.
mirrored volume
mirrored volume
A volume that uses space from two dynamic disks and provides fault tolerance. Also called a “RAID 1 volume.”
network-attached storage (NAS)
network-attached storage (NAS)
A storage device that has an enclosure, a power supply, slots for multiple HDDs, a network interface, and a built-in OS tailored for managing shared files and folders.
page file
page file
A system file in Windows used as a virtual memory and to store dump data after a system crash.
partition
partition
A logical unit of storage that can be formatted with a file system; similar to a volume but used with basic disks.
primary partition
primary partition
A division of disk space on a basic disk used to create a volume. It can be assigned a drive letter, be marked active, and contain the Windows system volume.
primordial pool
primordial pool
A collection of physical disks available to be added to a storage pool.
RAID 5 volume
RAID 5 volume
A volume that uses space from three or more dynamic disks and uses disk striping with parity to provide fault tolerance.
redundant array of independent disks (RAID)
redundant array of independent disks (RAID)
A disk configuration that uses space on multiple disks to form a single logical volume.
resilience
resilience
Another term for fault tolerance; indicates a disk arrangement’s capability to maintain data if a disk fails.
serial ATA (SATA)
serial ATA (SATA)
A common disk interface technology that’s inexpensive, fast, and fairly reliable with transfer speeds up to 6 Gb/s; used in both client computers and low-end servers and replaces the older ATA (PATA) technology.
serial attached SCSI (SAS)
serial attached SCSI (SAS)
A newer serial form of SCSI with transfer rates up to 6Gb/s and higher; the disk technology of choice for servers and high-end workstations.
simple volume
simple volume
A volume that resides on a single disk, basic or dynamic.
small computer system interface (SCSI)
small computer system interface (SCSI)
An older parallel bus disk technology still used on some servers but has reached its performance limits at 640 MB/s transfer rates.
solid state drive (SSD)
solid state drive (SSD)
A type of storage medium that uses flash memory, has no moving parts, and requires less power than a traditional HDD. Also faster and more shock resistant than a traditional HDD but costs more per gigabyte and doesn’t have as much capacity as an HDD.
spanned volume
spanned volume
A volume that extends across two or more physical disks, such as a simple volume that has been extended to a second disk.
storage area network (SAN)
storage area network (SAN)
A storage device that uses high-speed networking technologies to give servers fast access to large amounts of shared disk storage; the storage managed appears to the server OS as though it’s physically attached to the server.
storage layout
storage layout
The method used to create a virtual disk with Storage Spaces; includes simple, mirror, and parity.
storage pool
storage pool
A collection of physical disks from which virtual disks and volumes are created and assigned dynamically.
Storage Spaces
Storage Spaces
A new feature in Windows Server 2012/R2 that provides flexible provisioning of virtualized storage
striped volume
striped volume
A volume that extends across two or more dynamic disks, but data is written to all disks in the volume equally; provides no fault tolerance but does have a performance advantage over simple or spanned volumes.
system volume
system volume
A volume containing the files a computer needs to find and load the Windows OS.
thin provisioning
thin provisioning
A method for creating virtual disks whereby the virtual disk expands dynamically and uses space from the storage pool as needed until it reaches the specified maximum size.
VHD file
VHD file
The format virtual machines running in Hyper-V use for their virtual disks; can also be created and mounted with Disk Management and used like physical disks.
volume
volume
A logical unit of storage that can be formatted with a file system.
True
A solid state drive is a good candidate for storing the page file.
False
The biggest advantage in using virtual disks instead of physical volumes is the lack of portability.
False
A parity space storage layout is similar to a RAID 1 volume in that a parity bit is written to the spare drive.
False
Thin provisioning allocates all configured space immediately ensuring that the space is available for the specified virtual disk.
True
A disk that is initialized via the Disk Management mmc is initialized as a Master Boot Record (MBR) disk by default.
What special character cannot be utilized in an NTFS file’s name?
Resilient File System (ReFS)
What file system can repair minor file system issues automatically and supports up to 1 yottabyte of volume size?
data deduplication
What feature provides the ability to find identical sets of data on a SAN based storage array and reduce the identical sets to a single instance in order to reduce space?
RAID 0
A simple space storage layout is similar to which non-fault tolerant RAID technology?
New-Partition
What PowerShell cmdlet can be used to create a new volume?
Version 3
What SATA version supports transfer speeds up to 6 Gb/s?

metadata
Modern file systems use what component to describe information about files, such as time stamps and attributes?
The disk pool is moved to an offline state until more physical storage is added.
If a disk pool becomes full how does Windows Server 2012 respond?
A volume must be accessible using Windows 9x.
Under what circumstance would an administrator choose to format a volume using the FAT file system?
True
The page file should be on its own volume.
Network Attached Storage
What type of storage typically shares files utilizing standard network protocols, such as Server Message Block (SMB), Network File System (NFS), and File Transfer Protocol (FTP)?
Solid State Drive (SSD)
A(n)___________ uses flash memory and the same type of high-speed interfaces, such as SATA or SATA express, as traditional hard disks.
iSCSI
The most commonly used network technologies within SANs are Fibre Channel and ______________.
Access Control List (ACL)
A(n)_______________________ determines who can access a file or folder and what can be done with the file.
