A small company wants the ability to print in full color but needs to pay a minimal initial purchase price for the printer Which of the following is the best option?
Inkjet printers are the best choice for a small company seeking full-color printing with a minimal initial cost. While they have higher operating costs (due to ink), they are affordable and capable of high-quality color output.
Why Not A (Thermal printer): Thermal printers are not designed for color printing and are typically used for labels or receipts.
Why Not C (Dot matrix printer): Dot matrix printers are outdated, noisy, and do not support full-color printing.
Why Not D (Laser printer): Laser printers have lower running costs but a higher initial purchase price, especially for color models.
CompTIA A+ Exam Reference: Core 2 (220-1102), Section 4.6, printer types.
A customer reports that a text-only document prints with unrecognizable characters. The print preview correctly displays the document. Which of the following is the most likely cause of the issue?
The Chief Information Security Officer asks a technician to inventory desktop PCs to determine which ones meet the requirements for Secure Boot. The technician must also configure the PCs for non-user-controllable keys. Which of the following are necessary to meet the enhanced security requirements? (Select two).
Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide)
To run Secure Boot, the system must have:
UEFI firmware (not legacy BIOS)
Secure Boot is a UEFI feature that validates bootloaders using digitally signed keys stored in secure firmware.
TPM (Trusted Platform Module)
The TPM stores cryptographic keys in tamper-resistant hardware, enabling secure key management that cannot be altered by normal users.
CompTIA materials describe TPM as essential for enhanced platform security and for storing validated boot keys when Secure Boot is enabled.
Together, UEFI + TPM provide:
Verified boot loader
Hardware-level key protection
Prevention of unauthorized OS tampering
Non-user-controllable secure key storage
Why the other options are incorrect
A . VDI -- Virtual desktops; unrelated to Secure Boot hardware requirements.
B . BIOS password -- Helps protect firmware settings but is not required for Secure Boot.
E . Disabled boot drive -- Irrelevant to Secure Boot.
F . USB permissions -- Not part of Secure Boot requirements.
Final Answe r: C, D
A user connects a PC to a projector and configures the projector to use HDMI. However, when the user tries to use the projector, the projector shows a black screen with the message ''HDMI2 no signal found.'' The user reports that the projector worked properly during a previous meeting. Which of the following should the user do to fix the issue?
The error message ''HDMI2 no signal found'' indicates that the projector is set to an input source that is not currently receiving a video signal. According to CompTIA Core 1 (220-1201) display and troubleshooting objectives, input source selection is one of the first items to verify when an external display shows a black screen but powers on correctly.
Many projectors have multiple HDMI ports (HDMI1, HDMI2, etc.). If the PC is connected to a different HDMI port than the one currently selected, the projector will display a ''no signal'' message even though the cable and device are functioning properly. Changing the input source to match the connected HDMI port resolves the issue quickly.
Replacing the bulb would not fix a ''no signal'' message, as the projector is clearly powered on and displaying text. Swapping the video cable is a valid troubleshooting step, but the explicit HDMI2 message points to an incorrect input selection. Updating video drivers is unnecessary when the device worked previously and the issue is isolated to input detection.
CompTIA emphasizes verifying correct input selection as a primary step when troubleshooting external display issues.
A customer reports slow network speeds. Which of the following components is most likely failing?
ANetwork Interface Card (NIC)is the hardware responsible for network connectivity. If the NIC is failing or underperforming (e.g., due to a bad driver, hardware fault, or misconfiguration), it can causeslow or unstable network speeds.
Option A (CPU):A failing CPU affects overall system performance but not specifically network speed.
Option C (HDD):A slow hard drive causes application lag, but not poor network performance.
Option D (RAM):Affects multitasking and speed, not network throughput.
