5.8.5 Practice Questions Storage Spaces

List the steps the user needs to follow to add more disk space to a Storage Space in Windows 10.

1. Install a new storage device to the system. 2. Add free space on that device to a storage pool. 3. Allocate space to an existing storage space.

Windows 10 features a storage solution called 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 Explanation 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 such 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 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 that 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.

Allows you to reconstruct data if one of the storage devices fails.

Parity

Requires that you have at least three storage devices.

Parity

On a Windows 10, using Storage Spaces eliminates the need for which of the following tasks?

Repartitioning drives. Resizing volumes. Explanation Storage spaces eliminates the need for such tasks as: Repartitioning drives. Resizing volumes. Backing up data in order to repartition.

Does not provide redundancy

Simple

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?

Storage devices, which are physical drives such as SATA drives or external drives. Pools of storage, which are logically created from free space on storage devices. Storage spaces, which are logically defined units created from a pool of storage. Explanation Storage spaces are composed of three components: Devices are the hard disks or other types of storage from 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.
