Since only one user experiences the issue in a shared environment where everyone else has stable connectivity, CompTIA A+ suggests that the problem is most likely with the client device, not the network. The wireless card may be failing, overheating, or experiencing intermittent hardware faults.

If other Wi-Fi signals or EMI (electromagnetic interference) were the cause, multiple users would be affected. Frequency congestion (Option B) also impacts groups, not a single device.

CompTIA stresses that isolating whether the issue affects one user or many helps determine whether the fault lies with the network or device. Because the problem is isolated, the most probable cause is a malfunctioning wireless NIC in the user’s laptop.

CompTIA A+ emphasizes virtualization as an ideal solution during system phase-out or transition periods. The correct approach here is a P2V (physical-to-virtual) conversion and hosting the server in an Infrastructure as a Service (IaaS) environment. This removes the need for physical hardware while still keeping the application operational for its final year. IaaS provides full control over OS and applications, making it suitable for legacy systems that cannot be rewritten.

Colocation (Option A) still requires physical hardware. PaaS (Option C) is inappropriate because PaaS requires rewriting or replatforming the application. Shutting down the server after a backup (Option D) makes the application immediately unusable.

Thus, the best method is to convert to a virtual machine and host it on IaaS.

To boot from a USB drive, the user must configure the boot order in the system BIOS/UEFI to prioritize the USB device. This setting tells the computer to load the operating system from the USB device on startup.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.5 – Configure BIOS/UEFI settings:

“The boot order determines the sequence in which the system firmware attempts to find an OS to boot. Setting USB as the first boot device allows the computer to boot from a USB drive.”

When a laser printer intermittently fails to feed paper, the most common hardware cause is worn or dirty pickup rollers. These rollers grab the paper from the tray and move it into the printer. Over time, dust, paper debris, or worn rubber reduces their effectiveness, causing feeding issues.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.3 – Troubleshoot printing problems:

“If the printer is not picking up paper correctly or is experiencing paper jams, check and clean or replace the pickup rollers and separation pads as these are responsible for feeding paper into the print path.”

Other options like updating drivers, selecting paper size, or replacing toner will not resolve a mechanical paper feed problem.
