• Question 671:

  A technician needs to fix a computer that received a non-specific error after a scheduled computer restart. Which of the following is the best way to start troubleshooting?

  A. Update all of the firmware.
  B. Roll back all of the recent updates.
  C. Review the system event log.
  D. Search for the error on the internet.
  C. Review the system event log.

  ---

  Explanation

  The best way to start troubleshooting a non-specific error after a scheduled computer restart is to review the system event log. The system event log is a record of significant events that occur on the computer, such as errors, warnings, or

  information messages. The system event log can help identify the cause of the error and provide possible solutions.

  To learn more about troubleshooting methods and tools, you can refer to the CompTIA A+ Certification Exam Core 1 Objectives1 or the CompTIA A+ Core 1 (220-1101) Certification Study Guide2. These resources cover the topics that are

  tested on the CompTIA A+ Core 1 exam, which is one of the two exams required to earn the CompTIA A+ certification. The CompTIA A+ certification validates your skills and knowledge as an entry-level IT professional.

• Question 672:

  A customer has a Wi-Fi-capable laptop to use when traveling for work

  Which of the following will allow the laptop to stay connected when the user travels?

  A. Cellular card
  B. Wi-Fi extender
  C. Bluetooth
  D. GPS
  A. Cellular card

  ---

  Explanation

  A cellular card is a device that allows a laptop to connect to the internet using a cellular network, such as 4G or 5G. A cellular card can provide internet access when the user travels and does not have access to a Wi-Fi network. A cellular card may require a subscription plan from a cellular service provider. A Wi-Fi extender is a device that boosts the signal of an existing Wi-Fi network, but it does not provide internet access by itself. Bluetooth is a wireless technology that allows devices to communicate over short distances, but it does not provide internet access either. GPS is a satellite-based system that provides location and navigation information, but it does not provide internet access as well.

• Question 673:

  A technician is setting up three web servers foe a retail company that takes online orders for its products. Which of the following network host services should the technician use to ensure the servers' resources will be utilized efficiently?

  A. UTM appliance
  B. AAA server
  C. Spam gateway
  D. Load balancer
  D. Load balancer

  ---

  Explanation

  A load balancer is a network device or service that distributes incoming network traffic across multiple servers, based on various criteria, such as availability, capacity, performance, or location. A load balancer can ensure that the servers' resources will be utilized efficiently, as well as improve reliability, scalability, and security. A load balancer can be hardware-based or software-based, or a combination of both.

• Question 674:

  A user reports that the printouts from a laser printer have lines and smudges on them. The printer is also intermittently misfeeding the paper. Which of the following components should a technician replace to address this issue?

  A. Fuser
  B. Maintenance kit
  C. Corona wire
  D. Toner cartridge
  B. Maintenance kit

  Explanation

• Question 675:

  A technician receives a tablet that looks like it has a bulge inside. The bulge is pushing the screen away from the backplate. The tablet still turns on when it is plugged in, but the screen looks damaged and turns off when unplugged.

  Which of the following is the most likely cause of this issue?

  A. Malfunctioning power supply
  B. Damaged charge port
  C. Swollen battery
  D. Broken screen
  C. Swollen battery

  ---

  Explanation

  The most likely cause is a swollen battery, which occurs when the battery's internal components break down, causing a buildup of gas. This results in:

  Physical Symptoms: The battery bulges, pushing the screen away.

  Operational Symptoms: The device may still power on when connected to a charger but fails to hold a charge due to battery degradation.

  Option A (Malfunctioning power supply): Incorrect. Power supply issues affect charging but do not cause physical bulging.

  Option B (Damaged charge port): Incorrect. A damaged port can prevent charging but does not explain the bulge.

  Option D (Broken screen): Incorrect. A damaged screen does not cause the device to bulge; it is likely a secondary effect of the swollen battery. Safety Note: A swollen battery poses a risk of fire or explosion and should be replaced immediately following proper disposal procedures.

• Question 676:

  A technician is creating a new RAID array for a customer After interviewing the customer, the technician decides to implement a RAID array of striping without parity. Which of the following reasons would lead the technician to choose striping without parity instead of striping with parity?

  A. Uptime is the customer's biggest concern
  B. Speed is the most important consideration.
  C. Redundancy and speed are equally important
  D. Available storage space needs to be maximized
  B. Speed is the most important consideration.

  ---

  Explanation

  Speed is the most important consideration. Striping without parity, also known as RAID 0, is a RAID configuration that splits data across multiple disks without any redundancy. This improves the performance of read and write operations, as multiple disks can work in parallel. However, this also increases the risk of data loss, as any disk failure will result in losing all data on the array. Therefore, striping without parity is suitable for situations where speed is prioritized over reliability. According to the CompTIA Core1 objectives, one of the advantages of RAID 0 is increased speed. A research paper on RAID performance also confirms that RAID 0 has the highest throughput among all RAID levels.

• Question 677:

  A user attempts to connect a laptop to a projector but receives the following message from the projector: Out of Range. Which of the following needs to be addressed first?

  B. Check the video cable and replace it if necessary.
  C. Set the computer's display settings to extend/duplicate.
  D. Verify that the laptop video card driver is the most up-to-date version.
  A. Change the resolution settings.

  1.Identify the problem.

  Gather information from the user, identify user changes, and, if applicable, perform backups before making changes.

  Inquire regarding environmental or infrastructure changes.

  2.Establish a theory of probable cause (question the obvious).

  If necessary, conduct external or internal research based on symptoms.

  3.Test the theory to determine the cause.

  Once the theory is confirmed, determine the next steps to resolve the problem.

  If the theory is not confirmed, re-establish a new theory or escalate.

  4.Establish a plan of action to resolve the problem and implement the solution.

  Refer to the vendor's instructions for guidance.

  5.Verify full system functionality and, if applicable, implement preventive measures.

  6.Document the findings, actions, and outcomes.
