CompTIA 220-1201 - CompTIA A+ Core 1Exam (2025)

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.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.5, authentication mechanisms​.

Choppy or unintelligible audio is typically caused by issues with the microphone, such as poor quality, hardware defects, or misconfiguration.

Why Not A (Webcam): The webcam handles video, not audio.

Why Not B (Digitizer): A digitizer relates to touchscreens, not audio.

Why Not C (Inverter): Inverters manage power for displays, not audio.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 3.6, audio troubleshooting​.

A PoE (Power over Ethernet) switch transmits both data and electrical power over Ethernet cables to devices like wireless access points or VoIP phones. This is especially useful in areas where separate power sources are not available.

Syslog is used to log system events and tasks performed by applications, providing a centralized record of activity.

Why Not A (Fileshare): Fileshares store files but are not designed for event logging.

Why Not C (Database): Databases can store logs but are not a logging mechanism themselves.

Why Not D (SAN): A SAN is a storage solution, not a logging tool.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, system monitoring and logging​.

A common reason for aPOST failureafter a motherboard installation isimproperly seated RAM. The system requires working memory to successfully complete POST. Reseating (removing and reinserting) the RAM ensures it's making proper contact with the motherboard.

Option A:Flashing the BIOS is not possible if the system won’t POST.

Option B:A dead CMOS battery can cause BIOS settings to reset, but it usually won’t prevent POST entirely.

Option D:Reinstalling the old motherboard is premature — basic troubleshooting steps should be completed first.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.5: Given a scenario, troubleshoot problems related to motherboards, RAM, CPU, and power.

USB-Cis a versatile connector capable oftransmitting data, video, audio, and power. With standards likeDisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more — all through one cable.

Option B (HDMI):Supports video and audio but not general data transfer.

Option C (DisplayPort):Similar to HDMI — supports video/audio but not general file transfer.

Option D (VGA):Legacy analog video only — no data or audio support.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.1: Identify common connector types.

SAS (Serial Attached SCSI) is a high-performance drive interface commonly found in enterprise environments and servers due to its reliability and speed. While SATA is more common in consumer systems, SAS is specifically designed for mission-critical applications, offering features like full-duplex operation and compatibility with SATA drives.

A. Run the maintenance application:

Most modern printers include a built-in maintenance application that can calibrate the print heads and correct alignment issues. Running this tool is the first step to address misalignment.

Incorrect Options:

B. Clean the rollers: Cleaning rollers is typically done to resolve paper feed or jamming issues, not alignment problems.

C. Upgrade the firmware: While updating firmware is beneficial for performance improvements, it is not the first step for fixing alignment.

D. Reinstall the drivers: Misaligned printing is usually hardware-related, not a driver issue.

Key Takeaway: The maintenance application should be run first to resolve alignment issues in a newly installed printer.

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.
