A+ 220-1201 Exam Dumps

An uninterruptible power supply (UPS) protects systems against power outages by providing temporary backup power, giving users time to save data and safely shut down.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 – Power protection:

“A UPS supplies backup power to prevent data loss and hardware damage during outages or surges, ensuring system integrity.”

CompTIA Exam Objectives 220-1101, Domain 3.3

Gaming laptops prioritize speed, low latency, fast read/write times, and quick loading. CompTIA A+ explains that NVMe M.2 SSDs provide the fastest consumer storage available due to their use of the PCIe bus, which delivers significantly higher performance compared to SATA-based drives.

HDDs (Options A and C) are mechanical and have slow seek times, making them unsuitable for high-performance gaming. SAS SSDs (Option D) are enterprise-grade, rarely used in laptops, and require SAS controllers not found in consumer systems.

Thus, a 512GB NVMe M.2 SSD offers the best performance, fastest boot times, rapid texture loading, and optimal gaming responsiveness fully aligning with A+ hardware performance recommendations.

Wireless coverage issues at the physical edges of a building are typically caused by weak RF signal strength. The CompTIA A+ study material says the best solution is to add additional wireless access points (APs) or implement a mesh system to extend coverage and eliminate dead zones.

Enabling 5GHz often worsens the issue because 5GHz has shorter range. Wi-Fi 6 NIC upgrades improve performance but do not increase signal reach. Flushing DNS does not affect wireless coverage.

Installing more APs ensures stronger coverage, better signal-to-noise ratio, and stable connectivity aligning with CompTIA’s wireless troubleshooting best practices.

Comprehensive and Detailed Explanation

CompTIA A+ describes satellite internet as:

A wireless broadband solution used where wired infrastructure is unavailable.

Most common in rural and remote areas.

Provides high-speed access where DSL, cable, or fiber cannot be deployed.

Thus, satellite internet is the primary option for rural high-speed access.

Why the other answers are incorrect

A. Fiber – Not available in rural regions due to high installation costs.

C. DSL – Requires phone lines and is distance-limited; rarely available in remote areas.

D. Cable – Requires existing cable TV infrastructure; usually not available rurally.

Final Answer: B
