CompTIA Updated 220-1101 Exam Questions and Answers by mikail

The issue described in the scenario is most likely caused by the incorrect heat sink being used on the CPU. The heat sink plays a critical role in dissipating heat from the CPU to prevent overheating. If the incorrect heat sink is used, it may not fit properly, leading to insufficient contact with the CPU. This can cause inadequate heat transfer, resulting in the CPU overheating. Overheating can lead to thermal stress on the motherboard, potentially causing shorts near the CPU location as the excessive heat can damage the motherboard's circuits and components.

General knowledge on the importance of proper heat dissipation in preventing hardware damage, particularly in scenarios involving CPU replacements and upgrades.

When upgrading a laptop's storage from an HDD to an SSD, especially in laptops with only a single bay for a hard drive, the most critical characteristic to consider is the form factor. The form factor must match the physical dimensions and interface of the original HDD to ensure that the SSD can fit into the bay and connect properly. Storage size (B) is important for capacity reasons, transfer speed (D) affects performance, and partition type (A) is a software configuration aspect, but the form factor (C) is crucial for the physical compatibility of the SSD with the laptop.

Data throttling, often implemented by network providers to manage bandwidth usage, can slow data speeds after a certain usage limit is reached. Turning off wireless would prevent uploads, while roaming and 5G status primarily affect connectivity rather than speed throttling. CompTIA A+ Core 1 objectives cover connectivity troubleshooting for mobile devices, including factors impacting network speed and performance.

Reinstalling RAM in different slots addresses possible issues with dual-channel configurations. If not installed correctly, the system might not recognize the full capacity. This solution is immediate and doesn’t incur extra costs, unlike replacing hardware. It reflects CompTIA A+ Core 1 exam objectives on hardware troubleshooting, specifically RAM installation and configuration​.
