• Question 472:

  An engineer is experiencing unexpected reboots on a graphics workstation when rendering complex 3-D models. The workstation is configured with a 115V power supply that is rated at 200W and connected to a UPS. The central processing unit contains 16 hyperthreaded cores, and a discrete graphics solution utilizing an 8-pin power connector is installed in a PCI Express x16 slot. Which of the following indicates where the technician should begin troubleshooting?

  A. The UPS, as 115V is insufficient for the configuration and should be increased to 220V

  B. The power supply, as 200W is insufficient when the GPU is heavily tasked

  C. The graphics card, as it is the component that triggers the unexpected reboots

  D. The motherboard, as only standard PCI slots should be used for high-end graphics cards, not PCI Express slots

  Correct Answer: B

  The unexpected reboots on a graphics workstation when rendering complex 3-D models may be caused by insufficient power supply. The workstation is configured with a 115V power supply that is rated at 200W, which may not be enough when the GPU is heavily tasked. The technician should begin troubleshooting by checking the power supply.

• Question 473:

  Which of the following components enables the input on a mobile device's touch screen?

  A. OLED

  B. Digitizer

  C. Inverter

  D. CMOS sensor

  Correct Answer: B

  The digitizer is the component that enables input on a mobile device's touch screen. It is a transparent layer that sits over the screen and detects the location of touch inputs. OLED (Organic Light Emitting Diode) is a type of display technology. Inverter is a component used in older LCD displays to provide power to the backlight. CMOS (Complementary Metal-Oxide-Semiconductor) sensor is a type of image sensor used in digital cameras and smartphones to capture images.

• Question 474:

  A user in a medical office contacts a technician regarding a printer that is used to print A4- sized labels. After the labels are printed, they mistakenly contain white space in the middle of the page. Which of the following would MOST likely be the cause?

  A. Contaminated fuser

  B. Worn rollers

  C. A misfeed

  D. Page orientation

  Correct Answer: D

  Page orientation is the most likely cause of the labels mistakenly containing white space in the middle of the page when printed on a printer in a medical office. The printer may be set to print labels in a different orientation than the orientation of the label sheet. This would cause the printer to print labels as if there were more paper on the sheet than there actually is, leading to white space in the middle of the labels. A contaminated fuser, worn rollers, or a misfeed would cause other types of printing issues, such as streaks, smudges, jams, or incomplete printing, and would not cause white space in the middle of the labels.

• Question 475:

  A company wants to use client-side visualization for application testing. Which of the following configurations would BEST support this goal?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 476:

  A technician identified an issue on a workstation, obtained details from the user, and made a backup of the system. Which of the following should the technician do NEXT?

  A. Determine the next steps to resolve the issue and document it.

  B. Design a plan of action to resolve the issue and implement the solution.

  C. Document the findings, actions, and outcomes.

  D. Establish a theory of probable cause, researching internally or externally as needed.

  Correct Answer: D

  Identify the problem.

• Question 477:

  An online retailer would like to add capacity to support increased sales. Additional servers have been installed. Which of the following should be used to ensure each new server is being properly utilized?

  A. Virtualization

  B. Clustering

  C. Load balancer

  D. Round-robin DNS

  Correct Answer: C

  https://www.resonatenetworks.com/2020/04/29/clustering-vs-load-balancing- whats-the-difference/

  A load balancer distributes network traffic evenly across multiple servers, ensuring each server is being properly utilized. This helps to prevent overloading of any individual server, which can cause downtime or slow response times for users.

  In this scenario, adding a load balancer would be the best way to ensure the new servers are being properly utilized. References: CompTIA A+ Certification Exam: Core 1 - Page 181

• Question 478:

  A field technician has been dispatched to a site with an internet outage. Upon arriving, the technician discovers that the POTS lines are not working as well. Which of the following technologies is the site MOST likely using?

  A. Fiber

  B. Cable

  C. DSL

  D. Satellite

  Correct Answer: C

  DSL (Digital Subscriber Line) uses POTS (Plain Old Telephone Service) lines to provide high-speed internet access. If the POTS lines are not working, it could cause an internet outage for DSL customers. Fiber and cable internet typically use different types of infrastructure, while satellite internet is not reliant on POTS lines. References: CompTIA A+ Certification Exam: Core 1 - Page 231

• Question 479:

  An administrator is configuring a corporate-owned smartphone for a new manager. The company requires the ability to wipe the phone's data remotely in the event of loss or theft and the capability to approve applications installed on the phone. Which of the following tools would BEST meet this need?

  A. Tethering to a corporate-owned laptop

  B. WPA2-Enterpise wireless

  C. Corporate enterprise email

  D. Mobile device management

  Correct Answer: D

  D. Mobile device management. A mobile device management (MDM) solution is specifically designed to provide centralized control over mobile devices and to help ensure the security and compliance of corporate data. An MDM solution can provide the ability to wipe the phone's data remotely in the event of loss or theft, and the capability to approve applications installed on the phone, which meets the requirements mentioned in the question.

  Tethering to a corporate-owned laptop, WPA2-Enterprise wireless, and corporate enterprise email can provide security and management capabilities, but they may not have the comprehensive control and management capabilities of a full-featured MDM solution.

• Question 480:

  A user, who is attempting to give a presentation via a projector in a conference room, reports the projector has video but no audio. Which of the following will MOST likely resolve the issue?

  A. Changing the input on the projector to VGA

  B. Changing the output on the PC to DVI

  C. Modifying the projector's refresh rate

  D. Utilizing an HDMI connection

  Correct Answer: D

  The issue of video but no audio on a projector in a conference room can be resolved by utilizing an HDMI connection between the PC and the projector. HDMI supports both video and audio signals and is commonly used to connect a PC to a projector for presentations. Changing the input on the projector to VGA, changing the output on the PC to DVI, or modifying the projector's refresh rate will not resolve the issue.
