• Question 951:

  A user contacted the help desk about files that disappeared from a laptop. The technician discovered during troubleshooting that the drive was corrupt due to a possible mechanical failure, but the files were still readable. Which of the following actions did the technician take during troubleshooting? (Select two).

  A. Checked S.M.A.R.T. information
  B. Made sure the replacement drive was compatible
  C. Ran CHKDSK
  D. Reseated the HDD connector
  E. Increased the page file size
  F. Updated the firmware
  A. Checked S.M.A.R.T. information
  C. Ran CHKDSK

  ---

  Explanation

  S.M.A.R.T.

  (Self-Monitoring, Analysis, and Reporting Technology) is a feature of hard drives that monitors various parameters, such as temperature, error rate, spin-up time, and seek time, to assess the health and performance of the drive.

  S.M.A.R.T.

  can also predict the likelihood of failure based on the historical trends of these parameters. A technician can check the S.M.A.R.T. information of a hard drive using various tools, such as the BIOS, the operating system, or third-party software. Checking the S.M.A.R.T. information can help the technician diagnose the cause and severity of the drive corruption and determine the best course of action. CHKDSK (Check Disk) is a command-line utility that scans the file system and the disk surface for errors and attempts to fix them. CHKDSK can also recover readable data from bad sectors and mark them as unusable. A technician can run CHKDSK on a corrupt drive using various options, such as /f (fix errors), /r (recover data), or /x (dismount the drive). Running CHKDSK can help the technician repair the drive corruption and retrieve the missing files.

• Question 952:

  A technician is replacing a computer with a connected point-of-sale system using a 9-pin serial adapter. The new computer does not have a 9-pin serial port. Which of the following ports can an adapter be installed on in order to connect to the point-of-sale system?

  A. HDMI
  B. Bluetooth
  C. USB
  D. Lightning
  C. USB

  ---

  Explanation

  A USB to 9-pin serial adapter can be used to connect the new computer to the point-of-sale system using a USB port. USB is a common and versatile port type found on most computers. If a technician is replacing a computer with a connected point-of-sale system using a 9-pin serial adapter and the new computer does not have a 9-pin serial port, an adapter can be installed on the USB port in order to connect to the point-of- sale system. A USB-to-serial adapter can be used to connect a serial device to a USB port on a computer.

• Question 953:

  A technician is troubleshooting a recently installed printer that is leaving multiple lines and streaks on print jobs.

  Which of the following should the technician replace first?

  A. Rollers
  B. Drum
  C. Toner
  D. Fuser
  C. Toner

  ---

  Explanation

  Streaks and multiple lines on print jobs are commonly caused by an issue with the toner cartridge, such as a damaged or improperly installed cartridge. The technician should replace the toner first as it is the most likely and simplest component to check.

  Why Not A (Rollers): Rollers primarily handle paper feeding and are less likely to cause streaking.

  Why Not B (Drum): While the drum can cause similar issues, the toner cartridge is easier to replace and should be checked first.

  Why Not D (Fuser): The fuser bonds toner to the paper, but it typically causes smudging rather than streaking.

• Question 954:

  A client has three locations within city limits that need to be networked. Vendor network requirements for all three locations are a minimum of 1GB.

  Which of the following are the types of networks that will MOST likely be used for internal office and office-to-office networking? (Choose two.)

  A. MAN
  B. LAN
  C. WAN
  D. PAN
  E. SAN
  F. WLAN
  A. MAN
  B. LAN

  Explanation

• Question 955:

  A printer is leaving vertical black lines on every print job. A technician runs a test job and sees the same patterned lines. Which of the following should the technician do first to resolve the issue?

  A. Replace the toner.
  B. Contact the vendor.
  C. Clean the rollers.
  D. Replace the paper.
  C. Clean the rollers.

  Explanation

• Question 956:

  A user printed several documents to a shared network copier and noticed that they have very faint color density. A technician investigates the issue and verifies that the printer had a maintenance kit installed recently. Which of the following next steps will MOST likely resolve the issue? (Select two.)

  A. Replace the toner cartridges
  B. Replace the fuser module
  C. Clean the paper tray rollers
  D. Adjust the printer settings
  E. Replace the developer
  F. Empty the waste toner bottlers
  A. Replace the toner cartridges
  C. Clean the paper tray rollers

• Question 957:

  Which of the following internet connection types is most likely to be used in remote locations?

  A. Fiber
  B. Cable
  C. Satellite
  D. DSL
  E. Cellular
  C. Satellite

  ---

  Explanation

  Satellite internet is most commonly used in remote areas where wired infrastructure (e.g., fiber or cable) is unavailable. It relies on satellite communication, making it suitable for isolated locations.

  Why Not A (Fiber): Fiber requires physical infrastructure, which is rarely available in remote areas.

  Why Not B (Cable): Cable internet relies on coaxial infrastructure, which is often unavailable in remote locations.

  Why Not D (DSL): DSL depends on existing telephone lines, which may not reach remote areas.

  Why Not E (Cellular): Cellular can work in remote areas, but satellite is often the only option for extremely isolated locations.

• Question 958:

  A projector's image begins to flicker during a presentation. The laptop display does not produce this issue.

  When a technician changes the resolution on the laptop, the issue persists. Which of the following is the NEXT step the technician should take?

  A. Check the connectivity of the VGA cable.
  B. Check the connectivity of the power cable.
  C. Change the aspect ratio on the laptop.

• Question 959:

  Which of the following is the best environment for an engineer to use for research purposes?

  A. Host
  B. Sandbox
  C. Simulated production
  D. Cross-platform
  B. Sandbox

  ---

  Explanation

  A sandbox is a virtual environment that isolates the engineer's research activities from the rest of the system. This allows the engineer to test, experiment, and modify the system without affecting the real data, applications, or settings. A sandbox is the best environment for research purposes because it provides a safe and controlled way to explore new ideas, simulate scenarios, and troubleshoot problems. A sandbox can also be easily reset or deleted after the research is done. References What is a Sandbox Environment? Chapter 4: Virtualization and Cloud Computing

• Question 960:

  A group of friends is gathering in a room to play video games. One of the friends has a game server.

  Which of the following network types should the group use so they can all connect to the same server and the internet?

  A. SAN
  B. MAN
  C. LAN
  D. PAN
  C. LAN

  ---

  Explanation

  The appropriate network type for this scenario is a Local Area Network (LAN), which is designed for small, localized networks, such as within a single building or room. LANs are ideal for gaming because they provide high-speed, low-latency connections.

  Option A (SAN): Incorrect. A Storage Area Network is used for data storage, not for gaming or general networking.

  Option B (MAN): Incorrect. A Metropolitan Area Network covers a city or campus, far exceeding the scope needed for a gaming setup in a single room.

  Option D (PAN): Incorrect. A Personal Area Network is designed for a single user, such as Bluetooth devices, and would not support multiple devices connecting to a game server.
