The best answer provided is A , although it is important to note that the question is somewhat misleading because it asks about motherboard selection but provides mostly incorrect or irrelevant motherboard-related options.

For high-performance workloads such as video editing and virtual reality (VR) using an Intel Core i9 processor and multiple graphics cards (multi-GPU setup) , system design considerations include high power consumption and significant heat output. In the CompTIA A+ Core 1 220-1201 objectives under hardware planning and troubleshooting, high-performance CPUs and multiple GPUs require adequate thermal management solutions , including advanced cooling systems (air or liquid cooling) to ensure system stability and prevent thermal throttling.

Why A is the best answer:

High-end CPUs like Intel Core i9 and multiple GPUs generate substantial heat.

Proper cooling is essential for maintaining performance under sustained load (video rendering, VR workloads).

While not strictly a motherboard feature, cooling is a critical system requirement for such a build.

Why the other options are incorrect:

B. Use DDR3 RAM for increased compatibility

Incorrect because modern Intel Core i9 platforms use DDR4 or DDR5 , not DDR3, which is obsolete and incompatible with current high-performance motherboards.

C. Verify there are two PCIe x1 slots for additional devices

Incorrect because PCIe x1 slots are used for low-bandwidth devices (sound cards, network cards), not graphics cards.

Multiple GPUs require PCIe x16 slots , not x1.

D. Select a motherboard with integrated graphics to support video output

Incorrect because high-performance systems with discrete GPUs rely on those GPUs for rendering. Integrated graphics are unnecessary and sometimes disabled when a dedicated GPU is installed.

Exam Insight (CompTIA A+ perspective):

In real-world A+ Core 1 scenarios, the correct motherboard selection for this requirement would focus on:

Multiple PCIe x16 slots (for multi-GPU support)

Compatible socket for Intel Core i9

Support for modern RAM (DDR4/DDR5)

Adequate chipset and power delivery (VRM design)

Proper cooling solution for thermal management

However, since those correct motherboard specifications are not provided in the options, A is the only viable system-level requirement relevant to stability under high-performance load .

The correct answer is A. NFC (Near Field Communication) .

According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices, NFC is commonly used for short-range wireless communication between devices. In the context of mobile printing:

NFC-enabled printers allow a user to tap a mobile device (phone or tablet) to the printer to initiate a print job instantly without needing to configure Wi-Fi credentials or use cables.

This is particularly common in mobile-friendly environments like offices or public kiosks.

Why the other options are incorrect:

B. Hotspot : Provides an Internet connection, not a direct mobile-to-printer interface.

C. Infrared : Legacy technology largely replaced by NFC and Wi-Fi; rarely used in modern printers.

D. USB : Requires a wired connection, not suitable for sending a print job wirelessly from a mobile device.

The correct answer is A. Liquid cooling .

High CPU utilization and intensive graphics workloads generate significant heat. According to CompTIA A+ Core 1 220-1201 hardware objectives, ensuring proper thermal management is crucial for system stability and performance.

Liquid cooling provides more efficient heat dissipation than standard air cooling, allowing CPUs and GPUs to maintain optimal performance under heavy load and preventing thermal throttling. This is especially beneficial in gaming, video editing, rendering, or scientific computation workloads.

Why the other options are incorrect:

B. Advanced RISC : Refers to a type of processor architecture optimized for efficiency and specific instruction sets but does not directly address heat or cooling in high-utilization systems.

C. x86 processor : This is a general processor architecture; while important, it does not mitigate heat or improve cooling under heavy CPU/GPU usage.

D. Hardware security module : Focused on cryptographic operations and secure key storage, unrelated to CPU or GPU thermal management.

The correct answer is D. SMTP (Simple Mail Transfer Protocol) .

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

SMTP is the standard protocol used to send emails from a client to a mail server or between servers.

POP3 (Post Office Protocol 3) and IMAP (Internet Message Access Protocol) are used for receiving emails , not sending them.

LDAP (Lightweight Directory Access Protocol) is used for accessing and managing directory services, such as authentication and organizational information, not for email transport.

The correct answer is A. RJ11 .

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

RJ11 connectors are commonly used for telephone lines and data cables that use two pairs of wires (four wires total).

This connector is standard for analog telephone connections and DSL connections.

Why the other options are incorrect:

B. F-type: Used for coaxial cables, commonly in cable TV or broadband internet, not for two-pair data cables.

C. ST: A type of fiber optic connector, not used for copper two-pair wiring.

D. Molex: Primarily used for power connections in computer hardware, not for network or phone cabling.

The correct answer is A. Better compatibility .

According to CompTIA A+ Core 1 220-1201 objectives under Software Troubleshooting and Virtualization:

Application virtualization allows applications to run in an isolated environment on a client device without being installed directly on the operating system.

This improves compatibility , as applications can operate regardless of OS differences, avoiding conflicts with other installed applications or system configurations.

Why the other options are incorrect:

B. Reduced network latency: Application virtualization does not inherently reduce network latency; network performance depends on connectivity.

C. Secure telnet access: Telnet is unrelated to application virtualization.

D. Metered utilization: Metering refers to cloud service usage or billing, not a benefit of application virtualization itself.

According to the CompTIA A+ Core 1 (220-1201) virtualization objectives, a Type 1 hypervisor is known as a bare-metal hypervisor because it installs directly onto the physical hardware of a system rather than running on top of a traditional operating system. This architecture allows the hypervisor to manage hardware resources—such as CPU, memory, storage, and networking—without the overhead of a host operating system. Because of this direct interaction with the hardware, Type 1 hypervisors typically provide higher performance, better scalability, and improved stability compared to Type 2 hypervisors.

Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V (bare-metal deployment), and Citrix XenServer. These hypervisors are commonly used in enterprise data centers, cloud infrastructure, and large virtualization environments where multiple virtual machines must run efficiently on a single physical server. 🖥 ️

Option A (Host OS required) describes a Type 2 hypervisor, such as VMware Workstation or Oracle VirtualBox, which runs on top of an existing operating system. Option C (Lightweight OS) may describe some hypervisor environments but is not the defining characteristic. Option D (Local configuration options) is also not specific to Type 1 hypervisors.

Therefore, the key characteristic that defines a Type 1 hypervisor is that it performs a bare-metal server installation directly on the hardware

The correct answer is A. Clean the feed rollers .

According to CompTIA A+ Core 1 220-1201 objectives under Printers:

Frequent paper jams, particularly in high-use shared printers, are commonly caused by dirty or worn feed rollers .

Cleaning the feed rollers removes dust, paper debris, and toner residue that can prevent smooth paper feeding, especially when printing double-sided documents.

This is a standard preventive maintenance procedure that improves reliability and extends the printer’s operational life.

Why the other options are incorrect:

B. Use a different paper weight: A4 standard paper is appropriate; changing paper weight is unnecessary unless the paper is damaged or incompatible.

C. Replace the fuser unit: Fuser problems generally cause smudging or incomplete fusing, not frequent paper jams.

D. Change the toner cartridge: Toner issues affect print quality (light or streaky prints), not paper feeding or jamming.

When a printout is being cut off, CompTIA A+ Core 1 (220-1201) troubleshooting emphasizes checking the simplest, most likely configuration mismatch first—the printer’s paper size/source settings. Even if the user physically loaded the correct paper, the print job can still be formatted incorrectly if the printer driver, application, or printer itself is set to use a different paper size or a different tray. If the printer thinks it is using a smaller paper size (or a tray configured for smaller paper), it may clip the printable area and truncate the image at the edges.

Changing tray settings (paper size and paper source) aligns the printer’s configuration with the actual media installed, which is a standard first-step for issues related to formatting, clipping, and page boundaries. Image quality (DPI) affects sharpness, not cropping. File type rarely causes consistent edge cutoff compared with page setup mismatches. Adjusting image size could work as a workaround, but CompTIA best practice is to correct the paper/tray and page setup settings first so all prints format properly without editing the document each time.
