Which of the following indicates that a drive is unavailable when you check the status of a hard drive? (Select two.) Answer Failed Caution Bad Uncertain Down
Bad Down Explanation When a hard drive is unavailable, the status may be labeled Down or Bad. Caution means that you need to keep an eye on the hard drive, as it may fail in the near future. Uncertain means that no hard drive information is available. Failed is not a hard drive status.
What is the minimum number of storage devices you need in order to implement three-way mirroring for a storage space? Answer Two Seven Five Three
Five Explanation Three-way mirroring on a storage space requires at least five storage devices.
hen you configure Storage Spaces in Windows, you can include information redundancy with a feature called data resiliency. Match each type of data resiliency on the left with the appropriate description on the right. (Each data resiliency type may be used once, more than once, or not at all.) Drag Simple Two-way mirror Three-way mirror Parity Drop Requires at least three storage devices. Two-way mirror press delete to clear Requires at least five storage devices. Three-way mirror press delete to clear Does not provide redundancy. Simple press delete to clear Does not provide protection from a single storage device failure. Simple press delete to clear Requires at least two storage devices. Simple press delete to clear Protects your data if two storage devices fail at one time.
Requires at least three storage devices. Parity Requires at least five storage devices. Three-way mirror : Does not provide redundancy. Simple Does not provide protection from a single storage device failure. Simple Requires at least two storage devices. Two-way mirror Protects your data if two storage devices fail at one time. Three-way mirror Explanation Storage Spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for 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, which requires at least two storage devices. The data is written to two devices. Two-way mirroring 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, which 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, which 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 mirroring options, but performance is not as good if a device failure does occur. Parity requires only 50 percent more redundant space than a storage space.
Listen to exam instructions List the steps you need to follow to add more disk space to a storage space in Windows. Drag the correct step from the left to the correct step number on the right. (Not all steps on the left will be used.) Drag Add free space on a new storage device to a storage pool. Unmount the storage space that needs more disk space. Allocate space from the storage pool to an existing storage space. Install a new storage device on the system. Mirror the storage space to at least one other storage device. Drop Step 1 Step 2 Step 3
Step 1 Install a new storage device on the system. Step 2 Add free space on a new storage device to a storage pool. Step 3 Allocate space from the storage pool to an existing storage space. Explanation When you need to add more disk space to a storage space, follow the steps listed below. Install a new storage device on the system. Add the free space on that device to a storage pool. Allocate space to an existing storage space.
Listen to exam instructions On a Windows 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.) Answer Thin provisioning, which allows you to allocate more space than is available. Parity, which allows you to reconstruct data if device failure occurs. Storage space, which is a logically defined unit created from a storage pool. Storage pools, which are logically created from free space on storage devices. Mirrored data resiliency, which provides storage redundancy. Storage devices, which are physical drives such as SATA drives or external drives.
Storage pools, which are logically created from free space on storage devices. Storage space, which is a logically defined unit created from a storage pool. Storage devices, which are physical drives such as SATA drives or external drives. Explanation The Storage Spaces feature is comprised of the three components listed below. Devices - 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. Storage pools - a logical concept composed of the free space available on the specified storage devices. Storage pools are created from available disk space. Storage space - a logical unit of space created from a pool. One or more storage spaces can be created from a given pool. To the Windows system and the user, storage spaces appear as disks with typical drive letters (such as the E: drive or F: drive). Parity, thin provisioning, and data resiliency are specific benefits of the Storage Spaces feature.
You have a thin-provisioned storage space that suddenly unmounts. What is the MOST likely cause of this problem? Answer The storage space has run out of disk space. The storage space has become corrupted. A new storage device has been added to the pool. One of the disks in the storage space pool has crashed.
The storage space has run out of disk space. Explanation If a storage space runs out of disk space, that storage space will immediately unmount, leaving any I/O processes vulnerable to data corruption. Corruption in the storage space may cause issues with I/O processes, but this is not likely to unmount the storage space. While a disk device can cause problems in a storage pool if the device crashes, the issues will have more to do with data availability than an unmounted storage space. You can add a new storage device to a pool without interrupting any storage processes. This is one of the benefits of using virtual storage pools.
You want to set up storage spaces for several employees in your company with a maximum allocation of 100 gigabytes per drive. However, you only have 500 gigabytes of available space left in the pool where you want to create the storage spaces. Which Storage Spaces feature can you use to allocate more space than what is actually available? Answer Thin provisioning Pools Partition shrinking Data resiliency
Thin provisioning Explanation Thin provisioning (also called overbooking) allows you to allocate larger storage spaces than the disk space available in the pool. Data resiliency is the ability to allocate space for redundant information (such as two-way mirroring). A pool is a logically configured free space that is available on specified storage devices. Partition shrinking is done through Disk Management. Partition shrinking is not a feature of Storage Spaces.
Which of the following tasks does Windows Storage Spaces eliminate the need for? (Select two.) Answer Disk cleanup Drive repartitioning Volume resizing Defragmentation RAID array creation Hard drive formatting
Volume resizing Drive repartitioning Explanation Storage Spaces eliminates the need for such tasks as: Drive repartitioning Volume resizing Hard drive formatting, RAID array creation, defragmentation, and disk cleanup are all tasks that need to be done independently of the Storage Spaces feature.
What happens when you connect an external hard drive to a Windows PC? Answer Windows automatically assigns the new drive to a pool. Windows automatically partitions the new hard drive. Windows automatically assigns an available drive letter. Windows automatically initializes (formats) the new hard drive.
Windows automatically assigns an available drive letter. Explanation When you connect an external hard drive to a PC, Windows automatically assigns an available drive letter. Assigning the new drive to a pool, initializing the hard drive, and partitioning the hard drive are all tasks that you need to perform after connecting most new internal hard drives.
Windows features a storage solution called Storage Spaces. What is the name of the Storage Spaces feature that allows you to allocate space for redundant information using options that include two-way mirroring, three-way mirroring, and parity?
resiliency Explanation The Storage Spaces feature 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, which requires at least two storage devices. The data is written to two devices. Two-way mirroring 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, which 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, which 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 mirroring options, but performance is not as good if a device failure does occur. Parity requires only 50 percent more redundant space than a storage space.
