5.4.7 Practice Questions, A Perfect Review (TestOut, L1 CIT)

Jessica is concerned about losing data due to a hard disk failure. Her computer will only support a maximum of three disks. To protect her data, she has decided to use RAID (Redundant Array of Independent Disks).

Which of the following RAID types would give Jessica the BEST mirrored data protection?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

One of your customers wants you to build a personal server that he can use in his home. One of his concerns is making sure that he has at least one data backup stored on the server in the event that a disk fails. You have decided to back up his data using RAID.

Since this server is for personal use only, the customer wants to keep costs down. Therefore, he would like to keep the number of drives to a minimum.

Which of the following RAID systems would BEST meet the customer's specifications?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID 1 volume uses space on Disk 2 and Disk 3. Disk 2 fails. Which of the following is true?

• Data on the RAID 0 volume is accessible. Data on the RAID 1 volume is not.

• Data on both volumes is inaccessible.

• Data on the RAID 1 volume is accessible. Data on the RAID 0 volume is not.

• Data on both volumes is still accessible.

You have been asked to implement a RAID 5 solution for an engineer's desktop workstation. What is the minimum number of hard disks you can use to configure RAID 5?

• Two

• Three

• Four

• Five

• Six

A computer that is being used by the HR department needs to ensure that all of the data on that computer is protected from a single hard disk failure. The data needs to be read as quickly as possible, and the HR department would like to maximize drive use as much as possible. This computer can use up to three hard drives.

Which of the following RAID types would meet these requirements and provide the BEST data protection?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

Which of the following drive configurations uses striping with parity for fault tolerance?

• RAID 1

• RAID 10

• RAID 5

• RAID 0

You work for a small company as the human resources specialist. Since the company is fairly small, you are maintaining all of the employee information on your desktop computer, which is running Windows 11. This computer has two high-capacity hard disks. You want to ensure that this information is protected from a hard disk failure, so you want to set up a Windows software RAID system.

Which of the following would be your BEST solution?

• Use spanned volumes.

• Use striped volumes.

• Use mirrored volumes.

• Use RAID 5 volumes.

You want to create a software RAID 1 array on your Windows 11 workstation using Disk 1 and Disk 2.

What do you need to do with Disk 1 and Disk 2 before configuring them for a RAID 1 array?

• Convert the disks from basic to dynamic.

• Verify that both disks are the same size.

• Format both disks with the same file system.

• Convert the disk from dynamic to basic.

You are configuring a new system, and you want to use a RAID 0 array for the operating system using SATA disks and a special controller card that includes a RAID processor.

Which RAID method should you use?

• Software

• JBOD

• Operating system

• Hardware

You have configured Disk 3 and Disk 4 on your Windows 11 workstation as a RAID 1 array with the NTFS file system, and you have assigned F as the drive letter for the array. Each disk has an individual storage capacity of 1 TB.

However, when you check the available storage size of F, you notice that it only lists 1 TB (instead of 2 TB) of available disk storage space. What should you do to resolve the issue?

• Make sure both disks are set to dynamic instead of basic.

• Nothing. The RAID array is working as designed.

• Change the volume to a spanned volume.

• You need to change to a RAID 5 array.
