You have an existing Computer running windows 10. you want to configure a raid 1 array in the computer.

When you boot the computer windows does does not show the logical raid drive. What should you do?

Install the drivers for the raid controller

You are configuring a new system and you want to use raid zero array for the operating system using sata disks and the raid functionality built into the motherboard. Which of the following best describes the action you will take as part of the configuration?

Load the raid drivers during operating system installation

You are building a new computer that will contain to hard disks. To provide increased performance, you have decided to configure the devices using RAID technology. Which of the following would best meet your needs?

RAID 0

You have been asked to configure the Drives in a computer. The end-user wants to use striping without incorporating any fault tolerance. Which of the following would best meet these requirements?

RAID 0

A computer being used by the HR department needs to ensure that all the data on the computer is protected from a single disk hard drive failure. The data needs to be read as quickly as possible and HR department would like to maximize drive as much as possible. This computer can be used up to three drives. Which of the following raid types would meet these requirements and provide the best data protection?

RAID 5

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

RAID 5 Explanation RAID 5 also uses disk striping, but provides fault tolerance for a single disk failure. Disk striping breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. RAID 0 uses disk striping and offers no fault tolerance. A failure of one disk in the set means all data is lost. RAID 1 provides fault tolerance but does not use striping. A RAID 10 array nests a mirrored array within a striped array.

What is the advantage of RAID 5 over RAID 1?

RAID 5 improves performance over RAID 1
