Question#1

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?

A. Replace the bulb.

B. Swap the video cable.

C. Change the input source.

D. Update the video drivers.

Explanation:
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.

Question#2

Which of the following services are typically provided by a networked host to facilitate file sharing across different OSs? (Select two).

A. NTP

B. SMB

C. IMAP

D. FTP

E. ROP

F. LDAP

Explanation:
Comprehensive and Detailed Explanation
To enable file sharing across different operating systems, CompTIA A+ emphasizes the use of:
✔ SMB (Server Message Block)
The primary file-sharing protocol used by Windows.
Also supported on macOS and Linux (via Samba).
Allows shared folders, printers, and network browsing.
✔ FTP (File Transfer Protocol)
A cross-platform file transfer service supported by all major OSs.
Commonly used to upload/download files between systems of different types.
These two protocols are explicitly listed in CompTIA objectives under network protocols and file services.
Why the other options are incorrect
A. NTP C Time synchronization, not file sharing.
C. IMAP C Email protocol, not related to file sharing.
E. ROP C Not a file-sharing protocol (Return-Oriented Programming = security exploit).
F. LDAP C Directory service for authentication, not file sharing.
Final Answer B, D

Question#3

Which of the following is an advantage of using VDI?

A. Authentication is not required on a domain.

B. Licensing costs are minimized.

C. Less manual configuration is needed for each workstation.

D. A virus is automatically contained locally.

Explanation:
Virtual Desktop Infrastructure (VDI) hosts desktop environments on centralized servers. This allows rapid deployment and consistent configuration across multiple users, minimizing manual setup and easing IT management.
Option A: VDI still uses standard authentication methods.
Option B: Licensing can actually be more expensive due to virtualization software and backend servers.
Option D: VDI centralizes the desktop environment viruses would affect the virtual session, not be "contained locally."
CompTIA A+ Core 1 Exam Objective
Reference: Objective 4.1: Compare and contrast cloud computing concepts.

Question#4

A customer reports slow network speeds.
Which of the following components is most likely failing?

A. CPU

B. NIC

C. HDD

D. RAM

Explanation:
A Network 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 cause slow 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.
CompTIA A+ Core 1 Exam Objective
Reference: Objective 3.5: Given a scenario, troubleshoot problems related to wired and wireless networks.

Question#5

Which of the following systems most likely contains ECC memory?

A. A high-end gaming console

B. A file server

C. A smartphone

D. A laptop

Explanation:
Error-Correcting Code (ECC) memory is designed to detect and correct single-bit memory errors, increasing system reliability and data integrity. According to CompTIA Core 1 (220-1201) hardware and memory objectives, ECC memory is most commonly used in servers and enterprise-grade systems where uptime and data accuracy are critical.
A file server is responsible for storing, managing, and serving data to many users simultaneously. Memory errors in such systems could lead to data corruption, crashes, or security issues. For this reason, servers frequently use ECC memory in combination with server-class CPUs and motherboards that support error correction.
High-end gaming consoles prioritize performance and cost efficiency rather than fault tolerance, and they do not use ECC memory. Smartphones rely on low-power mobile RAM without error correction, and laptops typically use non-ECC memory unless they are specialized workstation-class systems, which is not indicated in this question.
CompTIA emphasizes that ECC memory is associated with mission-critical environments, particularly servers and enterprise systems, making a file server the most appropriate answer.
