A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected.
Which of the following can the technician do to further isolate the issue?

  1. Perform individual drive diagnostics.
  2. Run the chkdsk /f command.
  3. Rebuild the RAID array.
  4. Reconfigure the array as RAID 0.

Answer(s): A

Explanation:

Running diagnostics on each mirrored disk lets you identify which drive has developed bad sectors or electronics faults, isolating the failing disk before triggering a rebuild or replacement.



A company wants its RAID array set up so that it could lose multiple drives and still have redundancy.
Which of the following configurations should the company choose?

  1. RAID 0
  2. RAID 1
  3. RAID 5
  4. RAID 6

Answer(s): D

Explanation:

RAID 6 implements dual parity across the array, allowing any two drives to fail simultaneously without data loss, providing higher fault tolerance than RAID 5.



A user prints a spreadsheet in duplex mode. The spreadsheet is difficult to read because some of the columns spill onto the second side of the page.
Which of the following should the user do to prevent the issue but still print on both sides of the page?

  1. Turn off duplex printing.
  2. Try a smaller font size in the spreadsheet.
  3. Change the page orientation.
  4. Use a different print driver.

Answer(s): C

Explanation:

Switching from portrait to landscape gives you more horizontal space, allowing all columns to fit on each page while still printing on both sides in duplex mode.



Which of the following cable types can be used to transfer data and video?

  1. USB-C
  2. HDMI
  3. DisplayPort
  4. VGA

Answer(s): A

Explanation:

USB-C cables support USB data transfers and, when the host and cable support Alternate Mode, can carry video signals (such as DisplayPort or HDMI over USB-C), making them capable of handling both data and video on a single connector.



Which of the following types of RAM is best suited to handle errors within the module itself?

  1. DIMM
  2. Dual channel
  3. ECC
  4. SODIMM

Answer(s): C

Explanation:

Error-Correcting Code (ECC) RAM includes additional parity bits and logic to detect and correct single-bit errors on the fly, ensuring data integrity within the memory module.
