The correct answer is B. Inspect and replace the printer rollers .

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

Frequent paper jams with no visible obstruction are often caused by worn or dirty feed rollers , which fail to grip and feed paper properly.

Inspecting and replacing the rollers ensures smooth paper feeding and prevents repeated jams, particularly in high-use network printers.

Why the other options are incorrect:

A. Check for firmware updates: Firmware updates address software or functionality issues, not mechanical paper feeding problems.

C. Reseat the fuser assembly: Fuser issues typically cause smudging or incomplete toner adhesion, not paper jams.

D. Clean the corona wire: The corona wire affects toner adhesion and print quality, not paper feeding.

Comprehensive and Detailed Step-by-Step Explanation:

Random BSODs (Blue Screen of Death), intermittent freezing, and degraded performance under load are common symptoms of failing or faulty RAM (Random Access Memory). Here ' s the reasoning:

RAM Module (Correct Answer):

Faulty or failing RAM can cause random BSODs due to memory errors when the system attempts to read or write to corrupted memory locations.

Intermittent freezing, especially under performance-intensive operations, can occur because the CPU relies heavily on RAM for active processing tasks.

Over time, heat generated during usage can exacerbate RAM instability, leading to progressively worse performance throughout the day.

Solution: The technician should run a memory diagnostic tool, such as Windows Memory Diagnostic or MemTest86, to confirm if the RAM is at fault.

Incorrect Options:

A. Video Card: A faulty video card can cause graphical glitches, screen artifacts, or crashes, but it is unlikely to cause system-wide performance degradation and random freezing under normal operations unless the issue is specific to GPU-intensive tasks (e.g., gaming or video rendering).

B. HDD: A failing hard drive can cause system slowdowns and freezing, but it typically produces other symptoms such as read/write errors, boot failures, or clicking sounds. HDD issues do not usually cause BSODs unless critical system files are corrupted.

D. TPM (Trusted Platform Module): A TPM is a hardware-based security module used for encryption and secure authentication. It does not affect performance or cause BSODs or freezing under normal operation.

Key Takeaway:

The symptoms described (random BSODs, intermittent freezing, and degraded performance under load) are most likely caused by faulty or failing RAM. Memory diagnostic tools should be used to confirm the issue.

A workstation running three high-end GPUs requires a power supply capable of both high wattage and stable, reliable output. In CompTIA A+ power supply fundamentals, modularity and redundancy are emphasized for high-performance and mission-critical systems.

Modularity (B) allows the technician to connect only the necessary cables, reducing clutter, improving airflow, and enabling proper cable routing to multiple GPUs. High-end graphics cards require multiple PCIe connectors, and modular PSUs provide the flexibility to attach the exact number of required GPU power cables. This is important for systems where space management and cooling efficiency directly affect performance and component longevity.

Redundancy (D) is critical for mission-critical workstations used for 3-D modeling and rendering. A redundant power supply ensures that if one PSU module fails, the system continues running without interruption. CompTIA A+ highlights redundancy as a key feature in professional environments where uptime is essential. These systems typically use dual hot-swappable power modules to guarantee continuous power delivery.

The other options do not meaningfully address the requirements. A 12V output is standard on all PSUs. A 20-pin connector is outdated; modern motherboards use 24-pin. The 3.3V rail is not relevant to GPU loads, and 240 VAC input only refers to wall power compatibility, not PSU capability. Therefore, modularity and redundancy best meet the workstation’s needs.

A printer with text boxes AI-generated content may be incorrect.

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.

When installing copper network cable in spaces that serve as air-handling plenums, safety regulations require the use of plenum-rated cable. Suspended ceilings used for ventilation fall into this category. CompTIA A+ emphasizes that plenum spaces require cable with low-smoke, fire-resistant insulation made from specialized materials that limit toxic emissions during combustion.

Plenum-rated cabling (CMP) is designed to meet strict fire codes such as NFPA 70 (National Electrical Code). It prevents smoke-filled ventilation pathways, which could rapidly spread fire or toxic fumes throughout a building. Standard PVC-jacketed twisted pair cables are not permitted in plenum spaces because they produce thick, toxic smoke when burned.

Multimode cable refers to fiber optics, not copper cabling. Coaxial cable is used for broadband and certain RF applications but does not inherently meet plenum safety requirements unless specifically plenum-rated. Twisted pair describes the cable’s internal structure (Cat5e, Cat6, etc.), but it does not indicate the type of jacket. Only plenum-rated twisted pair is acceptable.

Therefore, the correct answer is Plenum, as it ensures compliance with safety standards and building codes, prevents hazardous conditions, and aligns with CompTIA best practices for structured cabling installations.

Assigning astatic IP addressto a network printer ensures it always retains the same address, allowing users and print servers to consistently reach it even after a reboot or network refresh.

Option B (Private address):Refers to address ranges (e.g., 192.168.x.x) doesn ' t guarantee address persistence.

Option C (Wi-Fi):Is a connection method, not a method of IP assignment.

Option D (Dynamic addressing):Via DHCP, which can change over time unless reservations are made (less reliable).

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.4: Given a scenario, install and configure printers.

To boot from a USB drive, the user must configure the boot order in the system BIOS/UEFI to prioritize the USB device. This setting tells the computer to load the operating system from the USB device on startup.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.5 – Configure BIOS/UEFI settings:

“The boot order determines the sequence in which the system firmware attempts to find an OS to boot. Setting USB as the first boot device allows the computer to boot from a USB drive.”

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

The correct answer is D. RAID 10 (also called RAID 1+0).

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

RAID 10 combines the mirroring of RAID 1 with the striping of RAID 0. This provides both high data availability (because each drive has a mirror) and improved performance (because data is striped across multiple disks).

RAID 10 requires a minimum of four drives and is suitable for servers that handle high I/O workloads while maintaining redundancy.

Why the other options are incorrect:

A. RAID 1: Provides mirroring for redundancy but does not improve performance as effectively as RAID 10.

B. RAID 0: Provides striping for performance but has no redundancy; a single drive failure results in data loss.

C. RAID 5: Provides parity and can tolerate one drive failure with decent read performance, but write performance is lower than RAID 10 and rebuilds can impact system performance under heavy load.

The correct answer is D. WLAN (Wireless Local Area Network) .

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

A WLAN is a wireless network that covers a limited area such as an office, building, or campus.

Using a heat map helps administrators determine optimal placement of access points, identify areas of weak signal, and plan coverage for employees’ devices.

Why the other options are incorrect:

A. SAN (Storage Area Network): Connects storage devices over a network; not used for wireless coverage.

B. PAN (Personal Area Network): Covers a very small area, such as a single person’s devices (Bluetooth, USB, etc.), not a whole office.

C. MAN (Metropolitan Area Network): Covers a city or large geographic area; too large for a floor plan.
