You have a server with Windows Server 2016 installed on Disk 0, a basic disk. You use the server to store users' documents. You have two more disks that you can install in the server. What should you do if you want to provide fault tolerance for users' documents? a. Convert Disk 0 to dynamic. Create a striped volume using Disk 0, Disk 1, and Disk 2. b. Create a RAID 1 volume from Disk 1 and Disk 2. c. Convert the new disks to GPT. Create a spanned volume using Disk 1 and Disk 2. d. Create a RAID 5 volume from Disk 0, Disk 1, and Disk 2.

b. Correct. RAID 1 provides fault tolerance for the users' documents.

performance is the main concern. What type of volume arrangement should you use? a. spanned volume b. RAID 1 volume c. RAID 0 volume d. RAID 5 volume

c. Correct. A RAID 0 volume increases read and write performance.

What type of volumes or partitions can be created on a basic disk? (Choose all that apply.) a. spanned volume b. striped partition c. extended partition d. simple volume

c. Correct. An extended partition can be created on a basic disk. d. Correct. A simple volume can be created on a basic disk.

Which of the following is true about GPT disks? a. They support a maximum volume size of 2 TB. b. GPT is the default option when initializing a disk in Disk Management. c. They use CRC protection for the partition table. d. You can't convert a GPT disk to MBR.

c. Correct. GPT disks use CRC protection for the partition table.

Which disk interface technology is specific to SSDs and uses the PCIe bus? a. eSATA b. SAS c. NVMe d. PATA

c. Correct. NVMe was developed as a high-speed interface for SSDs and uses the PCIe bus.

You want shared network storage that's easy to set up and geared toward file sharing with several file-sharing protocols. What should you consider buying? a. SAN b. DAS c. NAS d. LAS

c. Correct. Network-attached storage (NAS) is easy to set up and is geared toward file sharing with several file-sharing protocols.

On your Windows server, you're planning to install a new database application that uses an enormous amount of disk space. You need this application to be highly available, so you need a disk system with the capability to auto-correct from disk errors and data corruption. You also want a flexible storage solution that makes it easy to add space and supports deduplication. Which of the following is the best option? a. MBR disk with chkdsk b. NTFS format with EFS c. ReFS format and Storage Spaces d. GPT disk with shadow copies

c. Correct. ReFS with Storage Spaces meets the requirements for the storage.

Which of the following commands can verify a new partition you have configured in Linux? (Choose all that apply.) a. chkdsk b. vdisk c. fdisk d. sfdisk

c. Correct. fdisk can verify a partition in Linux. d. Correct. sfdisk can verify a partition in Linux.
