Free Practice Questions for CompTIA 220-1201 Exam

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.

USB-Cis a versatile connector capable oftransmitting data, video, audio, and power. With standards likeDisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more all through one cable.

Option B (HDMI):Supports video and audio but not general data transfer.

Option C (DisplayPort):Similar to HDMI supports video/audio but not general file transfer.

Option D (VGA):Legacy analog video only no data or audio support.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.1: Identify common connector types.

A hybrid cloud combines on-premises infrastructure with public cloud services. One significant advantage is that it allows organizations to keep sensitive data in a private environment to meet regulatory or data residency requirements, while still utilizing the scalability and cost-efficiency of the public cloud for other workloads. This ensures compliance with legal mandates about data location.

D. POST Code Beeps:

During the Power-On Self-Test (POST), the BIOS performs checks on system hardware, including RAM. If the RAM is faulty, POST may produce a series of beep codes indicating memory issues.

These beep codes are often the first sign of RAM-related problems, especially if the BSOD occurs randomly.

Incorrect Options:

A. Wrong BIOS configurations: Incorrect BIOS settings may cause boot errors, but they are less likely to cause random BSODs.

B. Continuous reboots: Continuous reboots could result from multiple hardware or software issues but do not specifically point to RAM.

C. Distended capacitors: Faulty capacitors typically affect the motherboard, not the RAM.

Key Takeaway: POST beep codes are a common diagnostic tool for identifying RAM-related issues.

Changing the page orientation(e.g., fromportrait to landscape) allows wider columns to fit on one side of the page. This maintains readability while continuing to use duplex printing.

Option A:Disabling duplex defeats the goal of printing on both sides.

Option B:May help, but could make the document harder to read if the font is too small.

Option D:Unlikely to resolve formatting issues related to layout and dimensions.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.7: Given a scenario, troubleshoot common printer problems.

When a device shows asnot connectedeven though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.

Option A:Entering a PIN is only relevant during initial pairing and may not be prompted again.

Option B:Turning off Wi-Fi doesn’t typically affect Bluetooth; they operate on similar frequencies but don’t conflict this way in normal use.

Option D:If Bluetooth were disabled, the device wouldn’t appear at all, not just show as “not connected.”

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.5: Given a scenario, connect and configure accessories and ports of mobile devices.

Comprehensive and Detailed Step-by-Step Explanation:

To determine the correct device, we need to understand how a DOCSIS (Data Over Cable Service Interface Specification) network functions in a Small Office/Home Office (SOHO) environment:

C. Cable Modem:

A cable modem is required to convert the signal provided by the ISP (Internet Service Provider) over a DOCSIS network into a format that is usable by the local area network (LAN).

DOCSIS is a standard for high-speed internet over cable television infrastructure, and the cable modem acts as the gateway between the ISP ' s coaxial network and the LAN.

Without the cable modem, devices in the LAN would not be able to access the internet.

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.

Mobile Device Management (MDM) allows IT departments to enforce compliance controls, such as restricting the installation of unapproved software, on laptops and mobile devices.

Why Not A (EDR): Endpoint Detection and Response focuses on detecting and mitigating security threats, not compliance controls.

Why Not B (VPN): Virtual Private Networks provide secure connections but do not enforce software installation policies.

Why Not D (SaaS): Software as a Service refers to software delivery models and does not enforce compliance controls.
