New Release 220-1101 A+ Questions

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 loopback plug is used to test the functionality of network interface card (NIC) ports to ensure they can send and receive data. It is a diagnostic tool that loops back the signal to the device, allowing verification of the network port's operation. This aligns with CompTIA Core 1 objectives related to troubleshooting wired and wireless networks and verifying network connectivity​.

If paper gets stuck at the last stage of printing, the rollers responsible for moving the paper through the printer are likely worn out or dirty.

Why Not B (Tray assembly): The tray assembly manages paper loading, not feeding during the print process.

Why Not C (Toner): Toner is unrelated to paper jams.

Why Not D (Printhead): Printheads manage ink/toner distribution, not paper movement.

Clicking and grinding noises indicate mechanical drive failure.

SMART data provides insights into the health and status of drives, helping identify failing components in the RAID array.

Why Not A (Run a magnet): This would damage drives.

Why Not B (Check if one drive is not level): Physical leveling is irrelevant.

Why Not D (Check OS logs): OS logs may provide limited information for RAID arrays.

Why Not E (Update RAID controller firmware): While important, it does not diagnose drive failure.
