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

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.

High resource usage along with frequentpop-upsare strong signs of amalware infection. The next logical step is toupdate anti-malware definitionsandrun a full scanto detect and remove threats.

Option A:Network performance is likely not the root cause local system behavior points to malware.

Option B:Drivers affect hardware functionality; they don’t resolve malware-related slowness.

Option D:DHCP issues usually cause IP conflicts or no network access, not CPU spikes or pop-ups.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 4.2: Given a scenario, detect, remove, and prevent malware using appropriate tools and methods.

BitLocker Drive Encryption in Windows requires aTrusted Platform Module (TPM)to encrypt the boot drive securely. The TPM is a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. It validates system integrity during boot and securely stores the encryption keys. If BitLocker cannot find a TPM or it is disabled in BIOS/UEFI, drive encryption cannot proceed.

BitLocker can function without TPM using a USB startup key, but this compromises some security and is not recommended for managed enterprise environments.

After determining the issue is likely on the remote server, the technician should test the theory to confirm the root cause before proceeding.

Why Not A (Document the findings): Documentation comes after confirming the issue.

Why Not C (Gather information): Information gathering is already completed.

Why Not D (Establish a plan of action): This is done after confirming the issue.

A VLAN (Virtual Local Area Network) is a network technology used to logically segment a physical network into multiple distinct broadcast domains, even if they share the same hardware.

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

“VLANs allow network administrators to segment a network logically, isolating broadcast traffic and improving security and management, regardless of the physical network layout.”

Other options explained:

MAC (Media Access Control) is a hardware address, not a segmentation method.

NIC (Network Interface Card) is network hardware, not for logical segmentation.

DSL (Digital Subscriber Line) is an internet connection type.

When a newly built workstation shows no response at all—no fans spinning, no indicator LEDs, and no POST activity—this indicates that the system is not receiving the signal to power on. Since the technician has already verified that all primary power connectors are fully seated (including the 24-pin ATX motherboard connector and the 4-pin or 8-pin CPU power connector), the most likely cause is that the case header pins are not connected to the motherboard.

According to CompTIA Core 1 (220-1201) hardware installation and troubleshooting concepts, the power button on the computer case connects to the motherboard via the front-panel (system panel) header, specifically the PWR_SW pins. If this connector is missing, improperly placed, or connected to the wrong pins, pressing the power button will do nothing because the motherboard never receives the power-on signal.

Incorrectly seated RAM typically allows the system to power on but prevents successful POST, often resulting in beep codes or error lights. An underpowered PSU usually causes instability, random shutdowns, or failure under load rather than complete inactivity. A faulty CPU fan connector generally triggers a BIOS warning or shutdown after power-on, not total failure to start.

This scenario directly matches CompTIA’s emphasis on checking front-panel connections as a primary step when a system does not power on at all.

RAID 5 provides fault tolerance by distributing parity information across all drives, allowing the array to continue operating if one drive fails. In a three-drive RAID 5 set, a single disk failure puts the array into a degraded state where it can still function, but it is at higher risk because losing a second drive before recovery would cause data loss. Since the system reports Drive 3 has failed after a power outage, the best next step to minimize risk is to replace the failed drive immediately and start the rebuild. Rebuilding regenerates the missing data blocks onto the new drive using parity, returning the array to a protected state.

Option B leaves the array degraded and increases exposure to a second failure. Option C (firmware upgrade) is not a first response in an active failure scenario and can introduce additional risk or downtime. Option D (restore from backup) is typically used when the array is unrecoverable or multiple drives fail; it is more disruptive and unnecessary when RAID 5 can recover from a single-disk failure. Therefore, replacing the defective drive and triggering an array rebuild is the correct next step.

Printers in SOHO environments must maintain a consistent IP address so devices can regularly locate them for scanning and printing tasks. CompTIA A+ emphasizes assigning static IPs to network printers to prevent address changes that occur with DHCP.

Laptops can remain DHCP clients because their address consistency is less critical. APIPA cannot communicate across networks and therefore should not be used. Assigning public IPs is incorrect and unsafe.

By giving the printer a static IP within the same subnet, all laptops can reliably access it, and the network remains organized and functional exactly as the A+ objectives recommend.
