RAID 1 can be configured to duplicate data to one or more additional drives. RAID 5 RAID 10 0.5 / 0.5 pts Question 2 While working on your computer, you receive the POST error, "Drive Not Recognized." You check your SATA cable to see if it is the problem, and it tests fine. You remove the hard drive and test it in a computer system known to be in good working condition and find that the hard drive is working. You can move data and check to make sure the OS files are not corrupt. You use a power supply tester to see if the voltage for the SATA power connection is correct, and the test shows the power is correct. You even check BIOS to make sure the hard drive can be recognized and find that all settings in BIOS are at default, so the system should recognize the hard drive. What might be the problem with your hard drive system? Hard drive jumpers are in wrong place. UEFI has the wrong hard drive type. Computer virus has deleted your MBR. Motherboard SATA port has gone bad.

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 3/16 Correct. The motherboard SATA port has failed. If you connect the drive to a different SATA port on the motherboard, the computer will boot provided the other port is fine. 0.5 / 0.5 pts Question 3 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. Correct. All 2.5 inch SSDs can be used in a desktop as well as in a laptop. To install a 2.5 inch SDD in a 3.5 inch bay in a desktop you need a universal bay kit as it creates a tailor-made fit. They are basically brackets that extend the width of a 2.5 inch SSD to 3.5 inches. The power and data interfaces are different on a laptop, so you need a special cable adapter. 0.5 / 0.5 pts Question 4

Select two. Improves overall disk performance Correct. RAID 0 writes across 2 or more physical disks evenly so that no disk receives all the activity, resulting in improved performance. RAID 0 improves performance but it does not provide fault-tolerance; if a drive in the RAID 0 configuration fails, data will be lost. To prevent against data loss and increase performance, use RAID 10. RAID 0 drives cost less than other RAID drives Prevent data loss in case of a drive failure RAID 0 provides an automatic disk backup RAID 0 requires at least two drives Correct. RAID 0 writes across 2 or more physical disks evenly so that no disk receives all the activity, resulting in improved performance. RAID 0 improves performance but it does not provide fault-tolerance; if a drive in the RAID 0 configuration fails, all data will be lost. To prevent against data loss and increase performance, use RAID 10. You could conceivably partition one drive in two and implement RAID 0 in software, but you would not gain any performance improvement or fault tolerance, thus defeating the purpose. 0.5 / 0.5 pts Question 5 You have a computer that is running low on storage, so you decide to install a second hard drive to store your files. You would like to partition the drive you just installed and end up with two volumes. In addition, you want to keep the original hard drive intact, which is where the Windows operating system resides.

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 5/16 What process would allow you to meet your objective? Boot from the Windows setup DVD or USB to prepare the new drive. Boot Windows and use Disk Management to prepare the new drive. Correct. If you are installing a second hard drive in a system that already has Windows installed on it, you should boot Windows and use Disk Management to prepare the new drive. You could use the Windows Disk Management utility to partition drives, create volumes, and group hard drives into a RAID array. Use the BIOS/UEFI setup screen to partition and format the new drive. Ensure the new drive is identical to the drive containing the Windows OS. 0.5 / 0.5 pts Question 6 You and a friend decide to watch a movie on your computer. The movie is saved on a second hard drive on your system. When you are ready to watch the movie, you can't find it on your computer. You try to locate the second hard drive, and it is no longer listed in Windows. What might be the problem with the movie and the hard drive? Video player app crashed. Hard drive has crashed.

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 6/16 Correct. Unfortunately, the movie and everything else on the drive appears to be missing. You can troubleshoot the hard drive system to see if you can repair the system. Movie has been deleted. Video card has crashed. 0.5 / 0.5 pts Question 7 Johan is a hard drive performance engineer working at a major storage device manufacturer. He needs to measure, record, and analyze the throughput, IOPS, and the latency of the different models of drives the company produces. What is the difference between these three parameters? Select three. Latency measures the amount of read write operations performed in one second. Latency measures the time required to process a data request or a transaction. Correct. Latency measures the time required to process a data request or a transaction. The lower the latency the better the performance. IOPS measures the number of read or write operations performed in one second. Correct. IOPS measures the number of read or write operations performed in one second. A higher IOPS indicates better performance.

Throughput measures the time required to process a data request or a transaction. Throughput is the amount of data flow through a point in the data path in one second. Correct. Throughput is the amount of data flow through a point in the data path in one second. A higher throughput value means better performance. 0.5 / 0.5 pts Question 8 Cirrus was hired to start a multimedia group at a major corporation. He has been asked to buy high-end equipment to ensure it will not be obsolete in three or four years. He buys a video camera capable of recording 8 MB/sec. What type of SD memory card should he use in the camera? C6 C10 V6 V10 Correct. SD memory cards with a Video Speed Class V10 designation are appropriate for video cameras; they have a minimum write speed of 10 MB/sec.

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 8/16 0.5 / 0.5 pts Question 9 Juridia buys new a 16 GB flash drive, she takes it out of the package, and tries to copy an 8 GB file to it. However, the operation fails with an error message indicating the file is too large. Which of the following statements are most likely to be true? Select two. The flash drive needs to be reformatted with the NTFS or exFAT file system. Correct. It is likely the flash drive was formatted with the FAT32 file system from the factory which supports files up to 4 GB in size. Formatting it using the NTFS or exFAT file system will remove the limitation. If you need to format a flash drive that has user data, make sure you back up the data first. The flash drive was shipped from the factory without low-level formatting. The flash drive was shipped from the factory with files that need to be deleted. The flash drive is not working properly and needs to be replaced with a new one. The flash drive has the FAT32 file system, which supports files up to 4 GB in size. Correct. If the flash drive has the FAT32 file system, it will only support files up to 4 GB in size. Reformatting the flash drive using the NTFS or exFAT file system will eliminate this restriction.

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 9/16 0.5 / 0.5 pts Question 10 Sharon believes the computer she is troubleshooting is having problems with the hard drive. She wants to test her theory and finds an older, known, good, SATA drive in the spare parts bin but notices the gold conductors in the SATA power connector are very distressed. Sharon also realizes that the spare drive also has a 4-pin power connector. What type of power connector will Sharon need to supply power to the hard drive? 4-pin P1 connector 4-pin Aux connector 4-pin Molex connector Correct. A 4-pin Molex connector is a power connector for hard drives; and many power supplies still use this connection for power. 4-pin 12 V connector 0.5 / 0.5 pts Question 11 Devon would like to install a new hard drive on his computer. Because he does not have a SATA port available on his motherboard, he has decided to purchase a NVME SSD hard drive. How can Devon attach a NVME device to his computer? (Select all that apply.) PCIe expansion card

NVME (non-volatile memory express) storage accelerates the transfer of data using the PCI Express bus. Devon can add a PCIe 4x expansion card to add the NVME drive. U.2 port on the motherboard Correct. If an U.2 slot is provided on the motherboard, you can add the NVME drive. This U.2 slot uses a cable and has an enclosure that protects the hard drive. U.2 devices are also hot swappable. M.2 slot on the motherboard Correct. An M.2 port might also be used to connect the NVME drive. M.2 hard drives do not generally have an enclosure to protect the drive. They connect directly to the motherboard via a slot or hardware connector. M.2 is not hot swappable. Internal USB connection 0.5 / 0.5 pts Question 12 Your computer has recently started to generate a few S.M.A.R.T messages. What is the most favorable thing you could do? Disable S.M.A.R.T in UEFI/BIOS Replace the CD/DVD recorder Delete files to create more space Backup your data immediately Correct. S.M.A.R.T. (self-monitoring, analysis, and reporting technology) is used to predict when a hard drive is likely to fail. Backup your data and replace the drive.

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 11/16 0.5 / 0.5 pts Question 13 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 Correct. Your motherboard may have a problem with the expansion slot that your RAID controller card is attached to. You can try the card in another slot to see if the slot is the problem. CPU RAM RAID controller Correct. Even though the diagnostics showed no errors, your card may have failed. This is evident because the entire hard drive on the RAID failed. Power supply 0.5 / 0.5 pts Question 14

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 12/16 Delonte has been using his computer at work every day for two years with no problems. The nature of his work requires him to frequently create and delete test files of different types and sizes. However, he is starting to notice that his computer is slowing down. What Windows tool can be used to verify Windows is relocating data to help with performance? Computer Management Defrag and Optimization tool Correct. Windows Defrag and Optimization tool is used to verify that Windows is defragmenting a magnetic drive and trimming an SSD. In a new hard drive, data is physically written in contiguous sectors. However, over time, when more files are created and deleted, files will be stored in disconnected fragments and potentially decrease performance. Defraggler Disk Cleanup 0.5 / 0.5 pts Question 15 Godiva's computer is having issues booting up. She troubleshoots and her best guess is that the BCD is corrupt. In her endeavor to plan a solution and implement it, what command should she include? chkdsk diskpart

The bootrec command is used to rebuild the BCD or Boot Configuration Data that holds the parameters Windows needs for a successful boot. 0.5 / 0.5 pts Question 16 Leroy buys three identical 2 TB SSDs to implement a fault tolerant RAID configuration. He configures RAID 1 using the three disks, and later discover that the total storage is only 2 TB. What alternative, if any, does Leroy have? Implement RAID 0 Implement RAID 01 Implement RAID 10 Implement RAID 5 Correct. RAID 5 will allow him to use all three drives, achieve fault tolerance, and 4 TB of usable storage. The other 2 TB will be used to store the parity data. He has no alternative 0.5 / 0.5 pts Question 17 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

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 14/16 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. Correct. When a drive in a RAID 5 configuration is replaced, the data is rebuilt using the data on the other two drives. For example, if the data you need was originally on the replaced drive, that data will not be available until it is rebuilt. This takes time. Even if no read activity is taking place, the drives are still active reconstructing the lost data on the replacement drive. The lost data includes both, actual user data and parity data. Once the data has been rebuilt, performance is restored. 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. 0.5 / 0.5 pts Question 18 Jessica wants to purchase a new hard drive. She wants a drive that has fast access because she will use it to edit videos on her PC. She also needs a lot of storage and wants to have at least 4 TB available to save her videos. Jessica wants to keep the cost down as much as possible. What type of hard drive should Jessica purchase? 5400 RPM magnetic HDD

2/12/24, 1:29 PM M04 Chapter 5 Review: 0BC-Spring 2024-Hardware/Software Support https://ivylearn.ivytech.edu/courses/1244100/quizzes/4407891 15/16 7200 RPM magnetic HDD Correct. In this scenario, the 7200 RPM HDD is the fastest magnetic hard drive. Its speed is enough for Jessica's video editing projects. SSDs offer faster access time than HDDs but also cost more. SSD HDD USB HDD 0.5 / 0.5 pts Question 19 This morning when Paul turned on his computer at work, it would not boot. Instead, Paul reported that he heard a loud clicking noise coming from inside his computer. What might be the problem with Paul's computer? Magnetic hard drive failed. Correct. Inside the hard drive are moving read/write heads and rotating platters; if they fail, they sometimes emit a loud clicking noise. This noise indicates that the hard drive is the problem. SSD hard drive failed. DVD drive failed. Video card failed. 0.5 / 0.5 pts Question 20

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. Correct. Before setting up a RAID 5 configuration, make sure any data is backed up as the configuration destroys all data on all drives added to the RAID configuration. Quiz Score: 10 out of 10
