Windows 10 features a storage solution call Storage Spaces. What is the name of the Storage Spaces feature that allows to allocate space for redundant information using options that include two-way mirroring, three-way mirroring, and parity?
Data resiliency Storage spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for storage spaces data resiliency include: -Simple, which does not provide redundancy. This option simply adds space from the storage pool to the storage space. When you select the Simple option, all of the data in the storage space is lost if one of the drives fails. -Two-way mirror requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as much device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure. -Three-way mirror requires at least five storage devices. The data is written to the three storage devices. This option provides redundancy for the data if two storage devices fail at one time. -Parity requires that you have at least three storage devices. This option uses parity information to reconstruct data if one of the storage devices fails. Parity uses less space for redundancy than the mirror options, but performance is not as good as the mirror options if a device failure occurs. Parity requires only 50 percent more redundancy space than storage space.

Which of the following raid types would meet these requirements and provide the best data protection?
RAID 5
Which of the following drive configuration uses striping with parity for fault tolerance?
RAID 5 Explanation RAID 5 also uses disk striping, but provides fault tolerance for a single disk failure.

Windows 10 features a storage solution called Storage Spaces. When you configure Storage Spaces you can include information redundancy with a feature called data resiliency. Match the types of data resiliency on the left with the appropriate descriptions on the right. Each type of data resiliency may be used once, more than once, or not at all.
Requires that you have at least three storage devices - Parity Requires at least five storage devices - Three-way mirror Does not provide redundancy - Simple Protects you from a single storage device failure - Two-way mirror Requires at least two storage devices - Two-way mirror Allows you to reconstruct data if one of the storage devices fails - Parity Protects your data if two storage devices fail at one time - Three-way mirror Storage spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for storage spaces data resiliency include: -Simple, which does not provide redundancy. This option simply adds space from the storage pool to the storage space. When you select the Simple option, all of the data in the storage space is lost if one of the drives fails. -Two-way mirror requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as much device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure. -Three-way mirror requires at least five storage devices. The data is written to the three storage devices. This option provides redundancy for the data if two storage devices fail at one time. -Parity requires that you have at least three storage devices. This option uses parity information to reconstruct data if one of the storage devices fails. Parity uses less space for redundancy than the mirror options, but performance is not as good as the mirror options if a device failure occurs. Parity requires only 50 percent more redundancy space than storage space.
On a Windows 10, using Storage Spaces eliminates the need for which of the following tasks? (Select two.)
Resizing volumes Repartitioning drives Storage spaces eliminates the need for such tasks as: -Repartitioning drives -Resizing volumes -Backing up data in order to repartition

On a Windows 10 workstation, you want to use the Storage Spaces feature to create a logical drive. Which of the following components are used to configure Storage Spaces? (Select three.)
Storage devices, which are physical drives such as SATA drives or external drives. Storage spaces, which are logically defined units created from a pool of storage. Pools of storage, which are logically created from free space on storage devices. Storage spaces are comprised of three components: -Devices are the hard disks or other types of storage form which storage pools are created. You can use a variety of devices such as SATA drives and external drives to create storage pools. -Pools of storage are created from the available disk space. A pool is a logical concept composed of the free space available on the specified storage devices. -Storage spaces define logical units of space created from a pool. One or more storage spaces can be created from the pool. To the Windows system and the user, storage spaces appear as disks with typical drive letters (e.g., E: drive, F: drive). Parity, thin provisioning, and data resiliency are benefits of Storage Spaces.
