CompTIA Updated 220-1101 Exam Questions and Answers by owais

A failing power supply can cause random system crashes and degraded performance as it struggles to maintain a consistent voltage, especially as the system demands increase over time. The CMOS battery only affects system time and settings, while the video card typically causes display issues rather than system-wide crashes. System memory issues often result in specific errors or performance issues rather than gradual slowdowns. CompTIA A+ Core 1 objectives highlight troubleshooting power supply issues as part of hardware and system maintenance.

Color gamut refers to the range of colors a display can accurately reproduce. For tasks like graphic design or photo editing, ensuring the screen's colors match the printed output is critical. Monitors with wide and accurate color gamuts (e.g., Adobe RGB) are preferred for these applications.

Option B (Pixel density): Incorrect. Pixel density affects image sharpness, not color accuracy.

Option C (Refresh rate): Incorrect. Refresh rate impacts motion smoothness but is unrelated to color matching.

Option D (Resolution): Incorrect. Resolution determines clarity and detail but does not influence color accuracy.

Comprehensive and Detailed In-Depth Explanation:

NFC (Near-Field Communication) operates at very short ranges — usually less than 4cm, and is ideal for quick, secure transactions like contactless payments. Bluetooth supports longer ranges (up to 10 meters or 32 feet) and is suited for ongoing connections like wireless headsets or file transfers.

Option A: Bluetooth is faster for large file transfers.

Option B: NFC uses less power, not more.

Option C: NFC does not require pairing — Bluetooth does.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.5: Given a scenario, connect and configure accessories and ports of mobile devices.
