• Question 194:

  A technician is troubleshooting an old desktop system that randomly shows a Windows BSOD or powers off unexpectedly. All system temperatures are within normal limits. Which of the following should the technician do NEXT?

  A. Visually inspect the motherboard capacitors.
  B. Verify all case fans are operational.
  C. Check that the BIOS version supports the installed CPU.
  D. Compare the software requirements with the installed RAM.
  A. Visually inspect the motherboard capacitors.

  Explanation

  BSoDs can be caused by poorly written device drivers or malfunctioning hardware, such as faulty memory, power supply issues, overheating of components, or hardware running beyond its specification limits. In the Windows 9x era, incompatible DLLs or bugs in the operating system kernel could also cause BSoDs.

• Question 195:

  A technician is troubleshooting an unresponsive touchscreen on a smartphone. The technician performs a hard reset, but the touchscreen remains unresponsive.

  Which of the following is the MOST likely cause of the issue?

  A. Missing drivers
  B. Virus infection
  C. Low battery
  D. Damaged digitizer
  D. Damaged digitizer

  ---

  Explanation

  The digitizer is a crucial component of a touchscreen device, responsible for translating touch actions into digital signals that the device can interpret. If a hard reset does not resolve the touchscreen's unresponsiveness, it is likely that the digitizer is damaged. Physical damage, such as cracks or heavy impacts, can impair the digitizer's ability to function correctly, leading to an unresponsive touchscreen. This type of hardware issue requires professional repair or replacement of the touchscreen assembly to restore functionality.

  Changes made:

  Replaced the contraction "it's" with "it is" for formal tone.

  Improved punctuation for clarity, such as adding a period at the end of the references section.

  Italicized "Mobile Devices 1101.docx" for correct formatting of document titles.

• Question 196:

  A technician needs to recommend an internet connection for a customer who travels around the world and wants to have connectivity while visiting remote camping locations. Some of the locations the customer visits have limited or unreliable cellular service. Which of the following connection types should the technician recommend?

  A. Satellite
  B. DSL
  C. Fiber
  D. Hotspot
  A. Satellite

  ---

  Explanation

  The connection type that the technician should recommend is Satellite. Satellite internet is a good option for people who travel around the world and want to have connectivity while visiting remote camping locations. It works by using terminals

  which can give you internet access in remote locations as long as they have a line of sight to the satellite in orbit above12. Since the customer travels to remote camping locations with limited or unreliable cellular service, the best recommendation is satellite internet connection. Satellite internet uses a dish to connect to satellites orbiting the earth, which can

  provide coverage anywhere in the world as long as there is a clear line of sight to the satellite. This is especially useful in remote areas where traditional terrestrial connections are not available.

• Question 197:

  A technician is installing a power supply in a workstation that contains a high-end graphics card, a 3GHz processor, and two cooling fans. Which of the following specifications should the technician verify before installing the new power supply?

  A. The wattage
  B. The chassis ventilation
  C. The motherboard's firmware
  D. The cables' color coding
  A. The wattage

  Explanation

• Question 198:

  The SSD in a user's computer failed. A technician is replacing the SSD and would like to mitigate future failures given that the user often runs many programs. Which of the following is the best solution?

  A. Increase the amount of virtual memory in the OS.
  B. Turn on Windows BitLocker.
  C. Virtualize the user's programs.
  D. Upgrade the amount of RAM in the computer.
  D. Upgrade the amount of RAM in the computer.

  ---

  Explanation

  Upgrading the amount of RAM in the computer helps reduce the reliance on virtual memory, which minimizes write operations to the SSD. Frequent write operations can wear out SSD cells over time, especially if the system relies heavily on virtual memory due to insufficient RAM. By increasing the physical RAM, the computer can handle multiple programs more efficiently without overloading the SSD, thus prolonging its lifespan.

• Question 199:

  Which of the following technologies can be used to harden guest virtual machines?

  A. Containerization
  B. Network isolation
  C. Resource reservation
  D. vTPM
  D. vTPM

  ---

  Explanation

  A virtual Trusted Platform Module (vTPM) is a technology that can be used to harden guest virtual machines by providing them with a secure cryptographic device. A vTPM can store encryption keys, certificates, and passwords, and can perform integrity checks on the guest operating system and applications. A vTPM can also enable features such as BitLocker and Credential Guard in Windows 10 virtual machines. A. Containerization is a technology that can be used to isolate applications from the underlying operating system and hardware resources. Containerization does not directly harden guest virtual machines, but rather provides a lightweight alternative to virtualization.

  B. Network isolation is a technology that can be used to separate network traffic between different virtual machines or groups of virtual machines. Network isolation can help prevent unauthorized access or attacks on guest virtual machines, but it does not harden them internally.

  C. Resource reservation is a technology that can be used to guarantee a minimum amount of CPU, memory, disk, or network resources for a virtual machine or a group of virtual machines. Resource reservation can help improve the

  performance and availability of guest virtual machines, but it does not harden them against security threats.

  D. vTPM is a technology that can be used to harden guest virtual machines by providing them with a secure cryptographic device. A

  vTPM can store encryption keys, certificates, and passwords, and can perform integrity checks on the guest operating system and applications.
