CompTIA 220-1201 Exam With Confidence Using Practice Dumps

CompTIA A+ explains that Wi-Fi issues at the edges of a building are typically caused by weak signal coverage, not client configuration. The recommended solution is to add additional wireless access points (APs) or mesh extenders to expand coverage and eliminate dead zones.

Enabling 5GHz would worsen the problem because 5GHz has shorter range and penetrates walls less effectively than 2.4GHz. Flushing DNS affects name resolution, not wireless signal strength. Upgrading the NIC to Wi-Fi 6 improves maximum throughput but still depends on sufficient signal, which the user does not have.

Additional APs ensure strong signal-to-noise ratio, consistent throughput, and stable roaming all solutions emphasized in the A+ wireless troubleshooting section. Therefore, option D is the correct and CompTIA-aligned fix.

Firmware is the embedded software on a device such as a printer. Manufacturers often release firmware updates to resolve hardware-specific functionality issues, such as scan-to-email or security vulnerabilities.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – Printer installation and maintenance:

“Firmware updates provide bug fixes and add new features for multifunction printers. Apply firmware updates to resolve device-specific issues.”

============

A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments.

Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches.

Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage.

Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage.

Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage.
