The mechanical engineer's PC shutting off during resource-intensive tasks like rendering could be caused by overheating or hardware issues. The two most logical steps to diagnose the problem are:

B. Check if the computer is overheating: Rendering is a CPU- and GPU-intensive task that generates heat. Overheating could cause the system to shut down as a protective measure. Checking the system’s temperature can help identify if this is the cause.

A. Listen for POST beeps when turning on the PC: POST (Power-On Self-Test) beeps can indicate hardware issues, such as with the motherboard, CPU, or GPU. Listening for beeps can help identify potential problems with these components.

Why the other options are incorrect:

C. Run chkdsk: This tool is used for checking disk integrity, but the symptoms don’t suggest a hard drive issue.

D. Reinstall the operating system: Reinstalling the OS is a time-consuming step and not typically necessary for hardware-related shutdowns.

E. Check if the graphics card is compatible with the motherboard: If the PC has been working for three years, the GPU is already compatible with the motherboard.

F. Replace the HDD: There’s no indication that the hard drive is causing the issue, as the problem occurs during rendering, which is more GPU/CPU-intensive.

This topic falls under the Hardware Troubleshooting domain in the CompTIA A+ Core 1 exam​.

A swollen battery can prevent a laptop from powering on as it disrupts connectivity or damages internal components. Identifying physical signs such as swelling or bulging is key, which aligns with the CompTIA A+ Core 1 objective on mobile device troubleshooting, specifically battery issues​.

Mobile Device Management (MDM) is the best solution for remotely managing security settings and configuring applications on tablets across branch offices. MDM allows administrators to control device security policies, push applications, track device locations, perform remote wipes, and manage many other aspects of mobile devices from a centralized console. While SSH, RDP, and VPN are useful for remote access and secure connections, they do not offer the comprehensive device management and configuration capabilities that MDM provides.

A significant increase in the number of reallocated sectors on a hard drive is a clear indication that the drive is experiencing physical damage or wear and tear that cannot be repaired through software means. Reallocated sectors are bad sectors that the drive's firmware has marked as unusable and moved data to spare sectors. This is often a precursor to drive failure. Therefore, the most prudent next step is to replace the hard drive to ensure data integrity and system reliability.
