NEW QUESTION # 323
A technician assembled a new PC. After a few minutes, the computer slows down and then shuts itself off.
Which of the following is the most likely cause of the failure?
- A. The GPU needs additional power.
- B. The motherboard is incompatible.
- C. The memory is insufficient.
- D. Thermal paste was not used.
Answer: D
Explanation:
The most likely cause of the failure is A. Thermal paste was not used.
Thermal paste, also known as thermal grease or thermal compound, is a substance that is applied between the CPU and the heat sink to improve the heat transfer and cooling of the CPU. Thermal paste fills the gaps and irregularities between the CPU and the heat sink, creating a better contact and reducing the thermal resistance .
According to some web search results , some signs and symptoms of not using thermal paste or using it incorrectly are:
*The CPU overheats and slows down or shuts down to prevent damage
*The CPU fan spins faster and louder to try to cool down the CPU
*The PC performance drops or becomes unstable
*The PC crashes or displays errors or blue screens
To fix this issue, the technician should apply thermal paste properly between the CPU and the heat sink, following these steps :
*Turn off the PC and unplug it from the power source
*Open the PC case and locate the CPU fan and heat sink
*Remove the CPU fan and heat sink from the motherboard
*Clean the surfaces of the CPU and heat sink with a lint-free cloth and alcohol
*Apply a small amount of thermal paste (about the size of a grain of rice) in the center of the CPU
*Reattach the heat sink and CPU fan to the motherboard, making sure they are aligned and secured
*Close the PC case and plug it back to the power source
The GPU needs additional power, the memory is insufficient, or the motherboard is incompatible are not likely causes of the failure, since they would not cause the PC to overheat and shut down after a few minutes.
The GPU needs additional power if it has a high power consumption that exceeds the capacity of the power supply or the PCIe slot. The memory is insufficient if it cannot handle the applications or tasks that are running on the PC. The motherboard is incompatible if it does not support the CPU, RAM, or other components that are installed on it. These issues may cause poor performance, errors, or crashes, but not overheating and shutting down.
NEW QUESTION # 324
A user brings a laptop to work every morning, correctly seats it in the docking station and then opens the laptop to begin work with no issues After the user left the laptop at home during a two-week vacation the laptop is no longer working. Upon returning to the office, the user reports that the keyboard and display are no longer working Which of the following should the technician ask the user to do first?
- A. Connect the laptop directly to the network.
- B. Press and release the laptop power button.
- C. Ensure the docking station is plugged in.
- D. Plug the laptop in and let it charge overnight
Answer: B
Explanation:
* Reasoning: Many docking stations provide power and functionality only when the laptop is properly powered on. If the laptop was powered off (e.g., during the vacation), docking it will not automatically turn it on. The technician should first ensure the laptop is powered on by pressing the power button.
* This is a common troubleshooting step when laptops in docking stations appear non-functional.
* Relevance to CompTIA A+ Core 1: This falls under Objective 5.2, which covers diagnosing and resolving common laptop and mobile device issues.
Why the Other Options Are Incorrect:
* A. Ensure the docking station is plugged in:
* While ensuring power to the docking station is important, the scenario specifies that the issue occurred after a vacation. The likelihood of the docking station losing power coincidentally during the vacation is low. Verifying the laptop's power state should be the first step.
* C. Plug the laptop in and let it charge overnight:
* There is no indication the laptop's battery is drained. While charging could resolve a dead battery, the user is more likely experiencing an issue where the laptop is powered off but docked, so charging overnight is not the best first step.
* D. Connect the laptop directly to the network:
* A network connection will not resolve the primary issue of the keyboard and display not working.
Addressing the laptop's power state is a higher priority.
Practical Example:
If a user returns from a vacation and places a powered-off laptop into a docking station, it may not automatically power on. Pressing the power button ensures the laptop is operational and communicating with the docking station.
CompTIA A+ Exam Objective Alignment:
* Objective 5.2: Troubleshooting common laptop issues, including power, display, and peripheral connectivity.

NEW QUESTION # 327
A customer's phone no longer charges fully. The phone only charges to 67% and then stops.
Which of the following should be replaced to resolve this issue?
- A. The SD card
- B. The charger
- C. The battery
- D. The phone
Answer: C
Explanation:
The battery is the component that stores and provides electrical power to the phone. The battery can degrade over time and lose its capacity to hold a full charge. This can cause the phone to stop charging at a certain percentage and run out of power faster. To resolve this issue, the battery should be replaced with a new one that is compatible with the phone model and manufacturer. To replace the battery, the customer may need to follow different steps depending on the type of phone and battery. Some phones have removable batteries that can be easily accessed by opening the back cover of the phone and sliding out the old battery. Other phones have non-removable batteries that are sealed inside the phone and require special tools and skills to open the phone and disconnect the old battery. In this case, the customer may need to contact the phone manufacturer or a professional service center for assistance.

NEW QUESTION # 329
A user receives the following error when trying to reboot a computer:
Which of the following is the MOST likely cause of this error message?
- A. Faulty RAID controller
- B. Failed hard drive
- C. Corrupted bootloader
- D. Incorrect storage device driver
Answer: B
Explanation:
The error message "Reboot and Select Proper Boot Device" indicates that the computer cannot find the boot device that contains the operating system12. This can happen if the hard drive that stores the operating system is damaged or failed, and the BIOS cannot detect it or read from it23. A failed hard drive can also cause other symptoms such as clicking noises, corrupted files, or slow performance4.
NEW QUESTION # 330
A technician has noticed that a monitored server is receiving a disk failure notice during startup. When the technician clicks to continue, the machine still seems to startup into Windows but at a much slower speed. The technician looks at the BIOS information and sees the machine utilizes a RAID 5 configuration. Which of the following does the technician MOST likely need to perform?
- A. Replace the failed drivers.
- B. Reinstall the HDD drivers.
- C. Restart the system.
- D. Rebuild The RAID.
Answer: D
Explanation:
The disk failure notice during startup indicates that one or more disks in the RAID array have failed. The machine still seems to startup into Windows but at a much slower speed because the RAID 5 configuration can tolerate one disk failure and still operate, but with reduced performance and reliability. The technician most likely needs to rebuild the RAID, which means replacing the failed disk(s) and restoring the data from the parity information. Reinstalling the HDD drivers will not fix the disk failure. Replacing the failed drivers is not a valid option, as drivers are software, not hardware. Restarting the system will not fix the disk failure either. References: https://www.comptia.org/blog/what-is-raid-0-1-5-6-10

NEW QUESTION # 333
An administrator needs to configure RAID for a video-rendering workstation at minimal cost. The solution should have high read/write performance and maximum drive storage utilization. Redundancy is not a concern. Which of the following RAID configurations should the administrator use?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Explanation
The administrator should use RAID 0 for a video-rendering workstation at minimal cost. RAID 0, also known as striping, is a RAID configuration that splits data evenly across two or more disks, without parity information, redundancy, or fault tolerance. RAID 0 has the following advantages and disadvantages:
High read/write performance: RAID 0 can increase the data transfer rate by using multiple disks in parallel. This can improve the speed and efficiency of video rendering, which involves processing large amounts of data. RAID 0 can also reduce the latency and seek time of the disks, as the data is distributed across multiple spindles.
Maximum drive storage utilization: RAID 0 can use the full capacity of the disks, without wasting any space for parity or mirroring. This can lower the cost and increase the storage space for the workstation.
For example, if two 500 GB disks are used in RAID 0, the total capacity of the array will be 1000 GB.
No redundancy or fault tolerance: RAID 0 does not provide any protection against data loss or disk failure. If one disk fails, the entire array will fail and the data will be unrecoverable. Therefore, RAID 0 should only be used for non-critical data that is backed up elsewhere, or for temporary files that can be recreated.

NEW QUESTION # 334
A startup is looking to immediately expand its data center but does not have the personnel or space to manage everything internally. The organization has multiple small offices and remote users with large computational and storage-solution requirements. Funding is not an issue for the company. Which of the following can BEST accomplish the company's goals?
- A. SON
- B. ISP
- C. SaaS
- D. laaS
Answer: D
Explanation:
Explanation
IaaS is a cloud computing model where a third-party provider hosts infrastructure components such as servers, storage, and networking on behalf of customers. This allows the startup to immediately expand its data center without the need for additional personnel or space to manage everything internally. Additionally, IaaS allows remote users to easily access the required computational and storage resources from multiple small offices.
Infrastructure as a Service (laaS) can provide the startup with the necessary computational and storage solutions without the need for internal management. laaS allows organizations to rent computing resources from a third-party provider instead of owning and maintaining them in-house.
