220-1201 Exam Dumps - CompTIA A+ Core 1 Exam (2026)

Comprehensive and Detailed Step-by-Step Explanation:

Modifying duplex settings to double-sided:

Printing on both sides of the paper (duplex printing) reduces paper usage, making it one of the most effective environmentally friendly printing initiatives.

It directly minimizes waste and supports sustainability goals in the workplace.

Incorrect Options:

A. Requiring user authentication for printing: While this can reduce unnecessary or unauthorized printing, it does not directly address environmental objectives like saving resources.

B. Locking down printing to only certain individuals: Limiting access may reduce printing overall, but it does not actively contribute to environmentally friendly practices like duplex printing.

D. Changing the print quality settings to best: Using the " best " print quality increases toner or ink usage, which is counterproductive to environmentally friendly objectives.

Key Takeaway:

Modifying duplex settings to enable double-sided printing is the best initiative to achieve environmentally friendly goals by reducing paper consumption.

Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.

Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.

Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.

Why Not D (Print server): A print server manages print jobs but doesn’t enforce authentication.

The appropriate network type for this scenario is a Local Area Network (LAN), which is designed for small, localized networks, such as within a single building or room. LANs are ideal for gaming because they provide high-speed, low-latency connections.

Option A (SAN): Incorrect. A Storage Area Network is used for data storage, not for gaming or general networking.

Option B (MAN): Incorrect. A Metropolitan Area Network covers a city or campus, far exceeding the scope needed for a gaming setup in a single room.

Option D (PAN): Incorrect. A Personal Area Network is designed for a single user, such as Bluetooth devices, and would not support multiple devices connecting to a game server.

Unmanaged switches require no configuration they simply need to be plugged in and start working immediately, making them ideal for simple network setups.

Managed switches provide advanced features such as VLANs, SNMP monitoring, port security, and traffic management, but require configuration.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 – Compare and contrast common networking hardware:

“Unmanaged switches operate out of the box with no configuration and are designed for simple connectivity. Managed switches allow for configuration, monitoring, and management of network traffic and security.”

CompTIA Exam Objectives 220-1101, Domain 2.2

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

CompTIA A+ Core 1 (220-1201) display technology objectives emphasize that contrast ratio is strongly influenced by how well a screen can produce true black. OLED (Organic Light-Emitting Diode) panels are known for the highest contrast ratios because each pixel is self-emissive—meaning it generates its own light. When an image requires black, OLED can turn individual pixels completely off, producing near-perfect black levels and extremely high (often “infinite”) contrast in practical terms.

By comparison, LCD panels require a backlight, so black areas still allow some light leakage through the liquid crystal layer, reducing contrast. LED in this context is typically an LED-backlit LCD, not a fundamentally different pixel technology; it improves brightness and efficiency but still relies on backlighting, so contrast is limited by backlight bleed and panel design. QLED is also a type of LCD technology that uses a quantum dot layer to enhance color and brightness, but it still uses a backlight, so it cannot match OLED’s per-pixel shutoff for black levels. Therefore, OLED is the best choice for the highest contrast ratios.

The correct answer is B. VGA .

VGA (Video Graphics Array) is an analog video interface . It transmits video signals as continuous electrical waves, which means the signal can degrade over distance or due to interference. VGA uses a 15-pin connector and is considered legacy hardware in modern systems, but it is still important for CompTIA A+ because you may encounter it in older equipment.

Why the other options are incorrect:

A. DVI

DVI can support both digital and analog signals , but in most modern contexts and exam questions, it is primarily treated as a digital interface (especially DVI-D). Since the question asks for a clearly analog cable, VGA is the best answer.

C. USB-C

USB-C is a digital interface that can carry video signals using protocols like DisplayPort Alternate Mode. It does not transmit analog video.

D. HDMI

HDMI is a fully digital interface used for high-definition video and audio transmission. It does not support analog signals.

Exam Tip (Core 1 220-1201):

Analog video = VGA

Digital video = HDMI, DisplayPort, USB-C, most DVI types

Final Answer: B. VGA

The correct answer is D. Restart the device .

According to CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:

Warning messages like this can be caused by malicious pop-ups or temporary software glitches . Restarting the device is the safest and quickest first step to clear temporary processes, refresh the system, and remove transient malware or pop-up overlays.

This approach addresses the issue without risking data loss or unnecessary downtime.

Why the other options are incorrect:

A. Force close all running applications: May help if a specific app is causing the pop-up, but restarting achieves this more reliably and fully resets background processes.

B. Replace the tablet with a newer device: Unnecessary and costly for a potentially temporary software issue.

C. Reset the device to default settings: This is a last-resort action, as it erases personal data and settings; it is not the first step.

The correct answer is B. Elasticity .

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud Concepts:

Elasticity refers to the cloud computing capability to automatically allocate and deallocate resources based on current demand. This ensures that applications have the necessary compute, storage, and network capacity during peak loads, and resources can be scaled down when demand decreases, optimizing efficiency and cost.

Why the other options are incorrect:

A. Hybrid deployment: Refers to using a combination of public and private clouds; it does not describe dynamic resource allocation.

C. Multitenancy: Describes the architecture where multiple users share the same infrastructure securely.

D. Metered utilization: Refers to charging based on resource consumption; it is a billing mechanism, not a dynamic allocation feature.
