Question 1

Which of the following services allows a remote user to access network resources?



Answer : D

A Virtual Private Network (VPN) provides secure remote access to network resources over the internet. WLAN provides local network access, SAN is for storage networks, and DHCP manages IP address allocation. CompTIA A+ Core 1 objectives emphasize VPN as a secure method for remote connectivity.


Question 2

While troubleshooting a user's smartphone issue, a technician notices that the display is visible but extremely hard to see. Which of the following is the most likely issue?



Answer : A

An inverter failure commonly causes dim screens as it fails to power the backlight, which is crucial for visibility. The LCD glass, IPS panel, and digitizer relate to touch and image display, not brightness. According to CompTIA A+ Core 1 objectives, understanding mobile device display issues, including inverter-related problems, is essential for effective troubleshooting.


Question 3

An employee is on a business trip and needs to upload daily conferences and meetings to the company's intranet. The uploading process is successful but was faster in the past. Which of the following is the most likely reason for the slowdown?



Answer : D

Data throttling, often implemented by network providers to manage bandwidth usage, can slow data speeds after a certain usage limit is reached. Turning off wireless would prevent uploads, while roaming and 5G status primarily affect connectivity rather than speed throttling. CompTIA A+ Core 1 objectives cover connectivity troubleshooting for mobile devices, including factors impacting network speed and performance.


Question 4

A technician is selecting a power supply for a new computer. There will be a large number of connected devices that must be powered by USB. Which of the following specifications should the technician prioritize?



Answer : B

USB devices rely on 5V output from the power supply, so the amperage rating at 5V is critical to ensure enough power is available for multiple USB devices. A modular connector count affects cable management, while a 20+4 power connector is standard for motherboard connections. Energy efficiency impacts overall power usage but is not specific to the needs of USB devices. This matches CompTIA A+ Core 1 objectives regarding power supply selection based on device requirements.


Question 5

When a user first turns on a PC, the performance is fine, but the PC becomes slower the longer it is used. The PC is also experiencing random system crashes. Which of the following is most likely failing?



Answer : B

A failing power supply can cause random system crashes and degraded performance as it struggles to maintain a consistent voltage, especially as the system demands increase over time. The CMOS battery only affects system time and settings, while the video card typically causes display issues rather than system-wide crashes. System memory issues often result in specific errors or performance issues rather than gradual slowdowns. CompTIA A+ Core 1 objectives highlight troubleshooting power supply issues as part of hardware and system maintenance.


Question 6

The printer in a main office repeatedly jams. Which of the following tasks should a support technician do to solve the issue?



Answer : A

A maintenance kit includes components like rollers and other parts that tend to wear out over time, which are common causes of printer jamming. Replacing toner, ink cartridges, or ribbons would not directly address paper jams. This troubleshooting step aligns with the CompTIA A+ Core 1 objective regarding maintaining printers for optimal performance.


Question 7

A technician sets up secure print and configures an NFC device that will authenticate users for access. Which of the following will the NFC device most likely use to authenticate?



Answer : A

NFC (Near Field Communication) devices commonly authenticate users through methods like badging, where a user's badge or ID card, enabled with NFC, grants access. Passwords and passcodes are not NFC methods, while biometrics are typically used in high-security areas with specific hardware. NFC's authentication, as outlined in the CompTIA A+ Core 1 objectives, facilitates access in environments needing convenient user verification.
