220-1101 exam dumps: questions 401 to 471 of 471

Correct answer: A

• A. Correct.

  Correct. A loud grinding noise from the drive bay, especially combined with freezes during file access, strongly suggests a failing mechanical hard disk drive. The first priority is protecting user data by performing a backup if the drive is still accessible, then replacing the drive. This matches standard troubleshooting best practices: identify probable hardware failure, prevent data loss, and replace the faulty component.

• B. Incorrect.

  Incorrect. Bad RAM can cause crashes, memory errors, or boot issues, but it does not create a mechanical grinding noise. A candidate might choose this because the system is freezing, but the physical noise and location in the drive bay point to storage hardware, not memory.

• C. Incorrect.

  Incorrect. A driver issue can affect drive performance or detection, but it will not cause a true grinding sound. This distractor reflects a common mistake of trying software fixes first when there is clear evidence of a physical hardware problem.

• D. Incorrect.

  Incorrect. Low virtual memory can cause sluggish performance and excessive disk activity, but it does not produce a mechanical grinding noise. The misconception here is confusing normal disk access with abnormal physical noises that indicate hardware failure.

Correct answer: A

• A. Correct.

  Correct. Repetitive clicking from a mechanical hard disk, especially combined with slow performance, freezes, and file access problems, strongly suggests a failing HDD. The best immediate action is to protect the data by backing it up as soon as possible and then replace the drive. This matches standard troubleshooting practice: identify likely hardware failure, preserve data, and replace the failing component.

• B. Incorrect.

  Incorrect. Defragmentation is not an appropriate first response to a drive making clicking sounds. On a failing HDD, additional read/write activity can worsen the problem and increase the chance of total failure before the data is secured. A candidate might choose this because slow performance can sometimes be helped by maintenance tasks, but the clicking noise points to hardware failure, not simple fragmentation.

• C. Incorrect.

  Incorrect. Low RAM can cause poor performance, excessive paging, and slow application response, but it does not cause a mechanical clicking noise from the drive bay. Someone might pick this because the system is slow and freezing, but the physical sound is the key clue indicating a storage device issue.

• D. Incorrect.

  Incorrect. A video card problem can cause display issues, boot problems, or artifacting, but it would not typically produce repetitive clicking from the hard drive area during file access. This distractor reflects a misunderstanding of matching the symptom location and behavior to the correct component.

Correct answer: A

• A. Correct.

  Correct. A very common cause of a "Bootable device not found" message after imaging or drive replacement is a mismatch between the firmware boot mode and the partition style/boot loader used by the restored operating system. For example, a Windows installation deployed in UEFI mode typically expects a GPT disk with an EFI System Partition, while a Legacy/CSM installation typically expects MBR boot records. If the SSD is visible in firmware, the next logical first step is to verify the boot mode and boot order settings match the installed image.

• B. Incorrect.

  Incorrect. The SSD being detected by firmware makes a total hardware failure less likely. A boot failure immediately after imaging is more commonly caused by configuration issues such as incorrect boot mode, missing EFI boot files, or an invalid boot order. Replacing the SSD before checking these settings would be premature and not aligned with efficient troubleshooting practice.

• C. Incorrect.

  Incorrect. System memory allocation in firmware is not a standard fix for a bootable-device error in this scenario. POST memory settings do not determine whether the firmware can find a valid boot loader on a detected SSD. This distractor reflects a misunderstanding between hardware initialization issues and storage boot configuration problems.

• D. Incorrect.

  Incorrect. Secure Boot can prevent untrusted boot loaders from loading, but standard properly deployed Windows images commonly work with Secure Boot enabled. The message in this scenario points more directly to the firmware not locating a valid boot target. Disabling Secure Boot should not be the first action unless there is evidence the image uses unsigned or unsupported boot components.

Correct answer: C

• A. Incorrect.

  Running CHKDSK with repair options can sometimes help correct file system errors, but on a drive that may be physically failing, it is not the best first step. Repair operations write changes to disk and can increase stress on unstable media, which may worsen data loss before important files are secured.

• B. Incorrect.

  Defragmenting is not appropriate for a suspected failing drive. It causes extensive read/write activity and can accelerate failure or increase corruption. It also does not fix hardware problems or recover corrupted files in a safe first-response manner.

• C. Correct.

  This is the correct first action. When symptoms suggest possible drive failure and data corruption, best practice is to preserve recoverable data before performing invasive diagnostics or repair steps. Minimizing writes helps reduce the chance of further corruption while the technician secures accessible files and prepares for hardware testing or replacement.

• D. Incorrect.

  Reinstalling Office addresses application-level issues, not symptoms such as random file names, missing saved files, freezes during transfers, and suspected storage corruption. The problem is more consistent with file system or disk issues than with Office itself.

Correct answer: A

• A. Correct.

  Correct. In RAID 5, one disk can fail without immediate data loss because parity information is distributed across the remaining drives. When the array is degraded, the proper first step is to replace the failed disk with a compatible drive and let the controller rebuild the array. This restores redundancy and is the standard recovery action recommended by RAID controller and server vendors.

• B. Incorrect.

  Incorrect. Reinitializing a RAID set typically destroys the existing array metadata and can result in data loss. A degraded RAID 5 array with only one failed disk is usually recoverable without reinitialization. Someone might choose this option if they confuse troubleshooting detection issues with a failed-drive rebuild procedure.

• C. Incorrect.

  Incorrect. Replacing all drives is unnecessary and increases risk. The array is designed to tolerate a single drive failure, so best practice is to replace only the failed drive first. A technician might think replacing everything is safer, but removing additional working disks can complicate recovery and extend downtime.

• D. Incorrect.

  Incorrect. RAID 0 provides no fault tolerance and converting an existing degraded RAID 5 array to RAID 0 is not an appropriate recovery step. This would not protect the data and could require reconfiguration that destroys the array. This distractor targets the misconception that performance should be prioritized over data protection during a failure.
