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

If a laptop has a USB flash drive connected during startup, the system firmware BIOS or UEFI may attempt to boot from that USB device depending on the configured boot order or boot priority. This can cause intermittent startup behavior because the laptop might sometimes detect the flash drive as a bootable device and try to load from it instead of the internal drive, leading to delays, boot errors, or unexpected screens. The correct fix is to adjust boot options in BIOS/UEFI: set the internal SSD/HDD as the first boot device, reduce the priority of USB boot devices, or disable booting from external media when appropriate for the environment. This addresses the root cause directly and prevents the presence of a flash drive from affecting normal startup.

BitLocker and TPM features relate to drive encryption and secure key storage and are not the primary reason the system is changing its boot behavior. “USB Enable” would control whether USB ports function, but disabling USB entirely is not a targeted first step and could break keyboards/mice or legitimate USB use. Therefore, the correct configuration item is Boot options.

SMB (Server Message Block)is a protocol used to access files and printers over a network, including across shared network folders. It enables the user to access and print files stored remotely on a shared directory.

Option A (ADF):Automatic Document Feeder hardware, not a network protocol.

Option B (USB):Used for direct physical connections, not for printing over networks.

Option C (PCL):Printer Command Language relates to printer drivers, not file sharing or access.

CompTIA A+ Core 1 Exam Objective Reference:

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

Containers provide lightweight virtualization, ideal for deploying microservices because they are isolated, portable, and require fewer resources than traditional VMs.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Virtualization and cloud computing:

“Containers package applications and their dependencies, making them ideal for running microservices efficiently and independently.”

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

When a printer only provides basic functionality (such as simple printing without duplexing, color management, stapling, or finishing options), this typically indicates that the system is using a generic or basic printer driver rather than the full-featured driver from the printer manufacturer. According to CompTIA Core 1 (220-1201) printing and troubleshooting objectives, advanced printer features are enabled through manufacturer-specific drivers, which expose all hardware capabilities to the operating system.

Operating systems often install default or class drivers automatically, especially when printers are connected via USB or discovered on a network. While these drivers allow basic printing, they do not include proprietary features such as high-resolution settings, tray selection, finishing units, or secure printing options. Installing the correct driver package from the printer manufacturer ensures full compatibility and unlocks advanced functionality.

Restarting the OS or modifying printer settings will not add missing features if the correct driver is not installed. OS-provided patches are designed to fix bugs or compatibility issues, not to enable vendor-specific printer capabilities.

CompTIA explicitly emphasizes verifying and installing manufacturer-recommended drivers as a key troubleshooting step when printer features are missing or limited.

Port flapping refers to a network port continuously going up and down, which can prevent the access point from fully coming online.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.4 – Wired and wireless troubleshooting:

“Repeated loss and restoration of network link is called port flapping and may result in network devices, such as access points, not coming online.”

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

To provision and run multiple virtual machines on a physical server, the administrator must use a hypervisor. A hypervisor is the virtualization layer that creates, runs, and manages virtual machines by abstracting physical hardware resources such as CPU, RAM, storage, and network adapters into virtual resources presented to each VM. Once the server is configured with the required hardware support (such as sufficient RAM/CPU capacity and virtualization features enabled in firmware), the hypervisor is the component that enables VM creation, allocation of resources, virtual disk creation, and VM lifecycle actions like start, stop, suspend, snapshots, and virtual networking configuration.

Device Manager is used to view and manage hardware devices and drivers on an operating system, but it is not a VM provisioning tool. Disk Management can partition and format disks, which may support storage preparation, but it does not create or run VMs. A Virtual LAN is a network segmentation method at Layer 2 and may be used in VM networking designs, but it does not provide virtualization itself. Therefore, the correct tool for provisioning virtual machines is the hypervisor.

Color gamut refers to the range of colors a display can accurately reproduce. For tasks like graphic design or photo editing, ensuring the screen ' s colors match the printed output is critical. Monitors with wide and accurate color gamuts (e.g., Adobe RGB) are preferred for these applications.

Option B (Pixel density): Incorrect. Pixel density affects image sharpness, not color accuracy.

Option C (Refresh rate): Incorrect. Refresh rate impacts motion smoothness but is unrelated to color matching.

Option D (Resolution): Incorrect. Resolution determines clarity and detail but does not influence color accuracy.

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. "

C. Initiate the system restore:

If the technician is confident that rolling back the system to a previous restore point will resolve the issue, the next logical step is to initiate the System Restore process.

System Restore allows the system to revert to a state before the OS update, which can eliminate the performance issues caused by the update.

Incorrect Options:

A. Document the findings: Documentation is important but should occur after resolving the issue.

B. Investigate any recent infrastructure changes: This is unnecessary if the issue is already attributed to the OS update.

D. Verify full system functionality: This step should be performed after the System Restore is completed.

Key Takeaway: When confident that rolling back will resolve the issue, the technician should proceed with initiating a System Restore to revert the OS.
