DisplayPort is a type of external monitor connection that provides the highest possible resolution for a PC.
DisplayPort supports up to 8K resolution at 60 Hz, or 4K resolution at 120 Hz, with a maximum bandwidth of
32.4 Gbps. DisplayPort also supports audio, multiple monitors, and adaptive sync. DisplayPort is compatible with other types of connections, such as HDMI and DVI, with adapters.

The technician should check the level of network utilization to determine if there is an excessive amount of traffic that may be causing the slow access to the network fileshare. This can be done using network monitoring tools to track the amount of data being transmitted on the network. References: CompTIA A+ Certification Exam Objectives 1001, 2.9

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.

If users are only able to save a small number of pictures on the microSD cards before running out of space, it suggests a formatting issue. Improper or incomplete formatting can lead to the card not utilizing its full storage capacity, resulting in significantly less available space for storing pictures. Formatting the microSD cards correctly would ensure the file system on the cards is set up properly, allowing the devices to use the full capacity of the cards for storage. Compatibility, UHD storage capability, and camera storage settings are less likely to be the issue in this scenario.
References: The necessity of proper formatting for storage devices is a fundamental aspect of managing digital storage, as outlined in the basic principles of digital storage and file systems.

NVMe (Non-Volatile Memory Express) is an interface protocol built especially for Solid State Drives (SSDs) to utilize the high-speed PCIe bus in computers. M.2 is a form factor that is commonly used for NVMe SSDs due to its compact size and direct connection to the PCIe interface, which is ideal for laptops. The 2.5" and
3.5" form factors are more commonly associated with SATA drives, and SD is a form factor used for removable flash memory cards, not for internal storage solutions like NVMe SSDs.
