Dumas, who has excellent mechanical aptitude, owns a computer with two hard drives. One drive is used for the operating system and the other drive is used for his personal files. He decides to install a third disk in a RAID 1 configuration to protect the disk with his files against data loss. He is not too concerned about data loss on the disk with the operating system because he could easily reinstall the OS, so that disk is not included in the RAID configuration. When he is done, he powers up his computer, no error messages are displayed, yet he is distraught because all his data is lost. Why would this happen?
The new drive was smaller than the original drive so the data from the original did not fit.
Since the new drive had no data, and RAID 1 mirrors data, it erased the data on the original.
The RAID expansion card is not seated properly so the RAID drives are not being detected.
He didn't back up his data. When RAID is configured all data on participating drives is lost.
You have a desktop system with a 2.5 inch 500 GB SDD and a laptop with a 200 GB SDD. You want to replace the 500 GB SSD on the desktop with a larger SSD and use the 500 GB SSD in the laptop. All data has been backed up. What factors do you need to consider?
An SSD with a form factor that fits a desktop will not fit in a laptop because they are different.
You need to buy a desktop to laptop disk caddy to successfully install the SSD in the laptop.
You can simply proceed to install the SDD from the desktop laptop directly in the laptop.
The power and data interfaces are different on a laptop, so you need a special cable adapter.
Your computer has three drives in a RAID 5 configuration. One of the drives fails so you replace it right away. Immediately upon replacing the drive you notice that the overall performance seems to have been degraded. You research the issue and conclude that this is the expected behavior. How can you rationalize this behavior?
You can't rationalize this behavior. It is a false statement. Performance should not be degraded.
It takes time to rebuild the data on the new drive. During this time performance is degraded.
When a RAID 5 drive fails, the data is temporarily written to pagefile.sys which is slower than RAID 5.
The new drive was not detected so the system continues to use RAID 5, but in a degraded mode.
Lucas works at a small production company that receives contracts to perform high-end video editing and rendering. He needs to buy systems with the ability to write 30 Gb/sec to a storage medium. What standard should the systems support?

NVM Express
Explain the difference between RAID 0, RAID 1, and RAID 5. Select two.
All three flavors of RAID need at least two disks for proper implementation.
RAID 1 has the capability of rebuilding lost using the data stored on the parity disk.
All three flavors of RAID could be implemented using hardware or software RAID.
RAID 0 stripes data across disks, RAID 1 mirrors data, and RAID 5 uses parity.
All three RAID configurations support fault tolerance and can prevent data loss.

Implement RAID 0
Implement RAID 01
Implement RAID 10
Implement RAID 5
He has no alternative

Keion works as a freelancer creating websites and designing logos for clients. He recently had a hard drive failure and lost work for a client, and he would like to prevent the same type of problem from happening again. Keion does not want to rely on a backup but would like a way to ensure that his data is safe on his computer. You recommend that he create a RAID array that will provide fault tolerance and not suffer data loss if one drive fails. What RAID configuration should you recommend to Keion?
RAID 0
RAID 1
RAID 5
RAID 10
You recently installed a new RAID controller card in a PCIe expansion slot on your computer. After setting up the controller, you transfer data from the backup you created over to the computer.

What might be the problem?
Power supply could not support the RAID controller.
Motherboard could not support the RAID controller.
Expansion card failed or became unseated.
Hard drives in the RAID have failed.

During routine maintenance on your server, you discover that one of the hard drives on your RAID array is starting to go bad. After you replace the drive and rebuild the data, you run diagnostics on the RAID controller card with no problems, so you believe you fixed the problem. The next morning you arrive at work and discover that the RAID has completely failed. None of the disks are working. Your server is still running because you installed the OS on a non-RAID disk, but all the data is missing, and the server shows that none of your RAID disks are found. What might be the problem with your server? (Select all that apply.)
Motherboard
CPU
RAM
RAID controller
Power supply
