220-1201 CompTIA A+ Core 1 Exam (2025) Free Practice Exam Questions (2025 Updated)

CompTIA A+ details that an Automatic Document Feeder (ADF) allows multi-page documents to be scanned automatically without manually placing each sheet on the flatbed. This drastically increases scanning efficiency for large documents.

Flatbed scanners require manual placement for every page. Duplexing scans both sides of a page but does not feed multiple sheets by itself. Orientation configuration only affects image alignment.

The ADF is explicitly highlighted in the A+ study guide as the primary feature used in business environments when scanning high-volume documents efficiently.

Thus, the ADF is the correct solution because it automates page feeding and dramatically reduces scanning time, especially for hundreds of pages.

A sandbox in virtualization allows testing an application in an isolated environment to observe its behavior without affecting the host system.

Why Not A (Run an application on multiple workstations): This describes application virtualization, not sandboxing.

Why Not C (Migrate a legacy application): This is about virtualization for legacy support, not testing.

Why Not D (Create a firewall): A firewall does not act as a sandbox for application testing.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 4.2, virtualization and sandboxing​.

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.

NVMe (Non-Volatile Memory Express) drives commonly use the M.2 interface and provide the highest performance for SSDs.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.2 – Storage devices:

“NVMe drives connect via the M.2 slot and provide the fastest data transfer rates available for storage devices.”

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.

Comprehensive and Detailed Explanation From Exact Extract:

RAID 6 uses two parity blocks, allowing it to tolerate the failure of two drives without losing data.

Modern motherboards require both the 24-pin ATX connector and a 4-pin or 8-pin CPU power connector. If the CPU power connector is not attached, the motherboard will receive power but the system will not boot. CompTIA A+ specifically lists this as a common mistake after replacing a power supply.

Insufficient wattage may cause instability, but usually the system still attempts to start. RAM does not prevent power-on if missing; instead, the system produces beep codes. Redundant PSUs are used in servers, not standard desktops.

Therefore, the missing CPU power connector is the most likely cause, and this scenario reflects typical troubleshooting steps outlined in A+ hardware diagnostics.

An eSIM (embedded SIM) allows users to change carriers and provision new cellular service without installing any physical hardware. It is managed via software and is ideal for international travelers who need to switch providers quickly.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 – Install and configure mobile device network connectivity:

"eSIMs provide carrier flexibility by enabling remote provisioning and profile switching, making it possible to connect to different networks without a physical SIM card."

Single-mode fiber (as well as multi-mode fiber) transmits data using beams of light, allowing for high-speed data transfer over flexible fiber-optic cables.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.1 – Networking media:

“Fiber optic cables transmit data using light. Single-mode fiber is used for long-distance, high-speed communication.”

A punchdown tool is specifically used to insert wires into a punchdown block in patch panels, which is typical for Cat 6 and similar cabling. It ensures a secure and correct connection by pushing the wire into a metal groove that slices the insulation.

CompTIA A+ repeatedly highlights that modern motherboards require two power connectors:

The 24-pin ATX main power connector

The 4-pin or 8-pin CPU power connector (EPS connector)

If the CPU power connector is missing, the system will not POST, even though other components appear to have power. This is a very common mistake after replacing PSUs and is specifically noted in CompTIA materials as a frequent cause of “no boot” scenarios.

Insufficient wattage usually causes instability, not a total failure to start. RAM is unrelated to powering on. Redundant PSUs are used in servers, not gaming PCs.

Thus, the missing CPU power connector is the correct diagnosis and matches A+ hardware troubleshooting guidelines.

RAID 1, also known as disk mirroring, duplicates data identically to two drives, ensuring full redundancy if one drive fails. Because the workstation only has two drives, RAID 1 is the only RAID level that provides fault tolerance under this constraint, exactly as described in the CompTIA A+ study guide.

RAID 0 offers no redundancy, RAID 5 requires at least three drives, and RAID 10 requires at least four drives.

RAID 1 is the recommended configuration for small environments or workstations that rely on data integrity and quick recovery, matching CompTIA’s guidance for redundancy in systems with limited drive availability.

When port issues persist after moving to a different switch port, the next logical troubleshooting step is to test the patch cable. Faulty or damaged cables are a common cause of network connectivity problems. Using a cable tester between the computer and the network closet verifies the integrity of the cable and rules out a physical layer issue.

From CompTIA A+ 220-1101 Official Study Guide, Objective 4.2 – Troubleshoot wired and wireless networks:

“If a device continues to experience connectivity issues after switching ports, test the cabling with a cable tester to check for continuity, shorts, or pinout issues before replacing hardware.”
