Module 7 – Configuring and Managing Data Storage

Merjem, a PhD student, is writing her thesis. She takes regular backup of her files and data. When taking backup, she chooses the Faster backup performance option in the Optimize Backup Performance window. Which of the following is true of the backup process in the given scenario?

Every backup only backs up data that has been modified since the previous backup.* Selecting Faster backup performance option performs incremental backups. This option performs a full backup the first time the backup is taken. However, subsequent backups only back up data that has been modified since the previous backup.

Zuber is configuring Windows Server 2019 as an iSCSI SAN device. He has successfully created an iSCSI virtual disk and a new iSCSI target. He is trying to connect his system to the new iSCSI target but he is facing a connection issue. What must be the cause for the connection issue?

IQN is not present in the access server list.* The iSCSI target identifies iSCSI initiators using IQN. If the IQN is not present in the access server lists, the connection issue will arise because the ISCSI target cannot identify the iSCSI initiator of the system.

How do you create a RAID level 1 volume with two disks in the Disk Management tool?

Right-click on the disk that you want to configure as a RAID volume and then click New Mirrored Volume to create a RAID level 1 volume with two disks* The New Mirrored Volume option is used to create a RAID level 1 volume with 2 disks as three-way mirroring is not possible in the Disk Management tool.

Which of the following statements is true of SAN devices?

SAN devices are functionally like an external USB drive.* SAN devices only provide storage to other systems using a SAN protocol and do not format or manage filesystems on this storage. Instead, the operating system that connects to the SAN device provides this functionality. As a result, a SAN device is functionally like an external USB drive.

How much storage space is reserved on a storage device to convert a storage disk to a dynamic disk using a Windows tool?

1 MB* The last 1 MB of storage on the device is automatically reserved to ensure that it can be converted to a dynamic disk, if necessary.

Sonia is configuring a RAID level 5 array with five disks. Each disk has the capacity to store 3 TB of data. What is the total storage size that Sonia can use to store data?

12 TB* In RAID level 5, one fifth of the toral storage size is reserved for parity information. The total storage is 5*3 = 15 TB; the storage reserved for parity information is 15 * (1/5) = 3 TB; and the combined storage capacity that Sonia can use is 15 - 3 = 12 TB.

Which of the following is a requirement for using Storage Spaces Direct?

A 10 GB Ethernet network interface with remote-direct memory access (RDMA) support is a must.* Microsoft only supports Storage Spaces Direct on systems that have a 10 GB or greater Ethernet network interface that supports remote-direct memory access (RDMA).

One of the disks on your computer is running low on storage space. You notice that there is unallocated space in the spanned volume. How will you use the unallocated space to increase storage space?

Right-click the volume on that disk and click Extend Volume to increase the size of the volume using the unallocated space* If there is unallocated space on one of the disks that contain a spanned volume, you can right-click the volume on that disk and click Extend Volume to increase the size of the volume using the unallocated space.

Due to their lack of storage-related features, FAT32 and exFAT are only used for removable media storage devices, not on permanent storage devices in servers

True*

Using a disk management tool, you can create a GPT on a disk that has an MBR when no partitions exist on a disk.

True* Provided that no partitions exist on the disk, you can right-click a disk in the Disk Management tool and click Convert to GPT to create a GPT on a disk that has an MBR, or click Convert to MBR to create an MBR on a disk that has a GPT.

A server rack containing data files, databases, web content, etc. is stored on an external SAN, which is connected to the Windows Server 2019 operating system via iSCSI. Which of the following is not likely to be achieved with this configuration?

Using hardware RAID externally to provide fault tolerance* SAN devices use hardware RAID internally to provide fault tolerance for the storage devices that they contain.

Which of the following is a term given to the software component in the operating system that connects to the SAN device via iSCSI?

iSCSI initiator* The software component in the operating system that connects to the SAN device via iSCSI is referred to as an iSCSI initiator

Trimming erases sections of the volatile memory chips on an SSD that no longer contain data, consolidating the existing data into fewer memory locations.

False* SSDs use non-volatile memory chips for storage.

The modern partition table is called the Master Boot Record (MBR) and uses storage devices that are larger than 2 TB.

False* The traditional partition table is called the Master Boot Record (MBR), and is limited to storage devices that are equal to or less than 2 TB in size. The modern partition table is called a GUID Partition Table (GPT), which uses storage devices larger than 2 TB.

__________ is a technology that can be used to transport SCSI data to a remote SAN device across a fiber optic cable at speeds of up to 128 Gbps. (fill in the blank)

Fibre Channel*

Identify the option that can be used to create storage pools that include storage devices from different servers on a network.

Storage Spaces Direct* Using Storage Spaces Direct, you can configure Storage Spaces to create storage pools that include storage devices from up to 16 servers on the network.

You are asked to create seven partitions in a storage device that uses an MBR. The device already has two partitions. However, you are also told that you cannot create more than a certain number of partitions on the storage device using an MBR. What would your next step be?

Create the partitions and label one of the partitions as extended* To overcome the limitation of partitions created on the MBR storage device, one of the partitions is labeled "extended," which can then contain an unlimited number of smaller partitions called logical drives.

Pablo is a system administrator in training. He is trying to manually defragment the F: volume in Becky's system. Help Pablo identify the correct method to perform manual defragmentation.​

Right-click the volume, click Properties, highlight the Tools tab, and click the Optimize button.* This sequence will optimize the volume and help it run more efficiently.

Sam, an administrator, sends out an HR policy file to Vicky, Mohammad, Charle, and Reena. They save the HR policy file on their home directories under a shared folder of Windows Server 2019 with different file names. As a result, the same copies of the file are present multiple times with different names. Reena opens and saves the file after making minor changes. What will happen to the files when Sam enables the Data Deduplication Service on Windows Server 2019?

A new copy of Reena's file is created and associated with the same file name.* After Reena modifies the file, a new copy of the file is created and associated with the same file name.

Parker runs the net start svsvc command at a Command Prompt to scan volume errors. He finds a corrupted spot on a volume. How can Parker directly go to the corrupted spot identified by the Spot Verifier service?

By using the /spotfix option with the chkdsk command* He can use the /spotfix option with the chkdsk command to only fix errors that were previously identified by the Spot Verifier service.

If you enable _______, the server administrator must supply the credentials you specify the first time that they configure the iSCSI initiator to connect to the iSCSI target. (fill in the blank)

CHAP*

Rishab is looking for ways to manage duplicate file content on his organization's shared drive. He enables data deduplication for this purpose. To save computing resources, he wants to change the settings such that data deduplication occurs in the evening. What must Rishab do to make this change?

Click Set Deduplication Schedule* The Set Deduplication Schedule button will allow Rishab to modify the performance options for the Data Deduplication Service.

Tara, an administrator, has added storage devices to the storage pool and selected the RAID level for the virtual disk using Server Manager. She wishes to allocate more space than is required for the current amount of data such that the system only uses the actual space it needs, enabling the actual size to grow with data. What would you do to achieve Tara's wish?

Create several thin-provisioned virtual disks* You can allocate more space than is required for the current amount of data, but the system only uses the actual space it needs, enabling the actual size to grow with the data.

Imran is associating a drive letter to a filesystem so that the drive letter can be accessed by the operating system. What is the term given to the process that Imran is carrying out?

Mounting* The term "mounting" refers to the process of associating a drive letter or folder to a filesystem so that the drive letter or folder can be accessed by the operating system.

While copying files between folders, it is possible to retrace and complete the transfer in case of a power failure if an NTFS-based filesystem is being used. The same cannot be said for a FAT32 filesystem. What do you think could be the reason for this difference?

NTFS is a journaling filesystem, while FAT32 is not.* NTFS is a journaling filesystem, while FAT32 is not. A journaling filesystem writes each step required to copy a file to a new location in a journal, which allows the file to complete the file copy after power is restored.

Madison is using the Backup Schedule Wizard from the Actions pane of the Windows Server Backup tool. He selects the backup configuration as Custom and specifies the items to be backed up. While adding the items to be backed up, he happens to select the System state option. What does this option create a backup of?

Operating system settings* This creates a backup of all operating system settings, including the Windows Registry, Active Directory database (for domain controllers), and boot loader files.

Rebecca is configuring a RAID with three storage devices. If she saves a file, the file will be divided into three sections, with each section written to separate storage devices concurrently, in a third of the amount of time it would take to save the entire file on one storage device. Which of the following RAID levels is Rebecca configuring?

RAID level 0* In RAID level 0, an individual file is divided into sections and saved concurrently on two or more storage devices, one section per storage device.

Which of the following RAID level configurations is not supported by Windows Server 2019?

RAID level 2* RAID level 2 is no longer used and was a variant of RAID 0 that allowed for error and integrity checking on storage devices.

Shaw, a server administrator, uses an iSCSI SAN protocol to transfer data to and from SAN devices at a speed of up to 40 Gb/s. He configures one of the SAN devices to provide storage to Jasper's Windows Server 2019 system. What should Jasper configure in his system to be able to connect to the storage?

The iSCSI target* To connect a Windows Server 2019 system to an iSCSI SAN, he must first ensure that the appropriate iSCSI target has been configured on the iSCSI SAN device and that his server can connect to it. These tasks must be performed using the configuration tools provided by the iSCSI SAN device manufacturer.

Nadia uses the Disk Management tool to create a simple volume in one of the disks. She specifies the simple volume size and chooses a drive letter. While selecting the formatting options, she modifies the default allocation unit size. What will happen if the allocation unit size is large?

The performance of file sharing applications will increase.* A large allocation unit size will increase the performance of file sharing applications, whereas a small allocation unit size will increase the performance of database applications
