A+ 220-1201 Book

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Incorrect because modern Intel Core i9 platforms use DDR4 or DDR5, not DDR3, which is obsolete and incompatible with current high-performance motherboards.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

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

A laser printer fuses toner onto paper using heat and pressure. Thicker paper often requires a higher fuser temperature to properly adhere the toner.

If the output smudges on thick paper but prints fine on standard paper, adjusting the fuser temperature is the first step before performing more invasive maintenance or replacing parts.

Why the other options are incorrect:

A. Install a maintenance kit: Typically includes rollers, belts, and other parts; this is not the first action if the issue is temperature-related.

C. Clean the transfer roller: Cleaning may improve print quality, but smudging on thick paper usually relates to insufficient fusing heat.

D. Install an OEM toner cartridge: The issue is unlikely to be caused by non-OEM toner if standard paper prints correctly.

The correct answer is A. Virtual LAN (VLAN).

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

VLANs are used to segment a physical network into multiple logical networks. By assigning the accounting department to a separate VLAN, users on other VLANs cannot access its network traffic without routing, thereby isolating sensitive departments while using the same physical switch.

VLANs improve security, reduce broadcast traffic, and allow network administrators to enforce access controls at the layer 2 level.

Why the other options are incorrect:

B. DHCP reservations: Ensure that specific devices always receive the same IP address, but do not restrict network access.

C. Content filtering: Controls web or application traffic based on content, not segmenting network access between departments.

D. Port security: Limits which devices can connect to a port but does not provide full network segmentation for an entire department.

The correct answer is A. Duplex.

In the CompTIA A+ Core 1 (220-1201) exam objectives under printer settings and configuration, duplex printing refers to printing on both sides of the paper automatically.

Using duplex printing is the best way to reduce resource consumption because:

It cuts paper usage in half, which is the primary resource being conserved.

It is ideal for multi-page documents and multiple copies.

It reduces physical storage and handling requirements.

Why the other options are incorrect:

B. Orientation

Orientation (portrait or landscape) changes the layout of the document but does not reduce resource usage.

C. Tray settings

Tray settings determine which paper tray is used (e.g., plain paper, letterhead), but they do not impact resource consumption.

D. Quality

Print quality (draft, normal, high) may affect ink/toner usage, but it does not reduce paper consumption as effectively as duplex printing, which is the main resource concern in this scenario.

Final Answer: A. Duplex
