220-1201 Exam Dumps - CompTIA A+ Questions and Answers

If paper gets stuck at the last stage of printing, the rollers responsible for moving the paper through the printer are likely worn out or dirty.

Why Not B (Tray assembly): The tray assembly manages paper loading, not feeding during the print process.

Why Not C (Toner): Toner is unrelated to paper jams.

Why Not D (Printhead): Printheads manage ink/toner distribution, not paper movement.

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

A sandbox is an isolated virtual environment, often used for testing code or software safely without affecting the host system.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Virtualization:

“A sandbox provides an isolated environment, often implemented as a virtual machine, to safely test applications or code.”

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

Virtual Desktop Infrastructure (VDI) hosts user desktops on centralized servers rather than physical PCs. Users access a virtual desktop session remotely through thin clients, laptops, or web browsers. The CompTIA A+ cloud-computing domain explains that VDI improves manageability, security, and resource efficiency by allowing IT to centralize OS images, apps, and updates.

SaaS provides applications not desktops. RMM is for monitoring and managing devices. Containers virtualize applications, not full desktops.

VDI enables organizations to avoid purchasing physical desktops while still delivering full computing environments to users, which aligns with the A+ virtualization objectives and remote-access concepts.

Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide)

When installing an operating system from external media (USB flash drive), the motherboard firmware must be instructed to check that device before checking the internal storage.

The CompTIA A+ official objectives describe that technicians must know how to access UEFI/BIOS settings and configure boot priority. Installing an OS from USB requires:

Entering UEFI/BIOS setup

Navigating to the Boot or Startup menu

Setting the USB drive as the first boot device

Saving and exiting to allow the computer to boot from the USB installer

This process is specifically referenced in CompTIA A+ material under “BIOS/UEFI settings,” where boot sequence / boot order is a fundamental configuration needed for OS installation.

Thus, the next step after assembling the PC is to modify the boot order to allow the system to boot from the USB installation media.

Why the other options are incorrect

A. BIOS password

Used for system access security; has no relevance to installing an OS from USB.

B. PXE boot

Used for network-based installations, not USB installations.

C. Secure Boot

Controls OS signature validation; not required to be changed for USB installation and is not the next required step.

Final Answer: D

Port 3389 is used by the Remote Desktop Protocol (RDP) for remote desktop connections in Windows environments. This port allows remote control and management of systems across the network.

A Virtual Private Network (VPN) creates an encrypted, secure tunnel across a public or untrusted network. It uses authentication credentials to ensure that only authorized users can connect, keeping data safe from interception.

A sandbox is a secure, isolated environment used to test potentially harmful software or code. It prevents the software from affecting the main system, allowing safe malware testing. Thismethod is standard in cybersecurity best practices.

B. USB-C:

USB-C is a versatile connector that supports charging, high-speed data transfer, and the ability to send audio and video signals (e.g., DisplayPort over USB-C).

It is used by most modern mobile devices and laptops because of its fast transfer speeds and power delivery capabilities.

Incorrect Options:

A. Lightning: Lightning is proprietary to Apple devices and does not natively support video output.

C. MicroUSB: MicroUSB is outdated and does not support video output.

D. MiniUSB: MiniUSB is an older standard and does not support modern features like video output or fast charging.

Key Takeaway: USB-C is the most versatile connector for charging and transferring data, audio, and video.
