Question 1

A user reports that a PC occasionally fails to start. The user restarts the PC, but the performance is degrading. The technician hears a strange repetitive ticking noise coming from the PC. Which of the following should the technician do first?



Answer : A

The ticking noise likely indicates a failing hard drive. The technician should attempt to extract data before the drive fails completely.


Question 2

A technician builds a custom computer for a customer, installing a high-end video card that draws 550W at maximum load. After a day of using the computer, the customer notices video loss and a burning smell. Which of the following should the technician troubleshoot first?



Answer : C

The ATX 3.0 16-pin connector provides power to high-end graphics cards, and a poor connection could lead to power issues and burning smells.


Question 3

A user's phone does not respond to touch. A technician inspects the phone but does not see any evidence of physical damage. The technician restarts the device, which does not fix the issue. Which of the following components should the technician examine next?



Answer : D

The digitizer is responsible for detecting touch input, so if the phone is not responding to touch, it is likely the digitizer is malfunctioning.


Question 4

A technician needs to adjust the VLAN to allow users in the sales department to access the marketing department's network resources. Which of the following should the technician configure?



Answer : C

To adjust the VLAN configuration, the technician needs to configure the switch. VLANs are configured on switches to segment network traffic logically, even if the devices are connected to the same physical network. By adjusting the VLAN settings on the switch, the technician can ensure that the sales department has access to the marketing department's network resources.

C . Switch: VLANs are configured on switches to logically separate or combine network segments.

Why the other options are incorrect:

A . Network card: A network card is a hardware component that connects a device to a network, but it does not configure VLANs.

B . Patch panel: A patch panel is used to organize and manage network cables but does not play a role in VLAN configuration.

D . Server: A server may host resources, but VLANs are managed at the switch level.

E . Hub: A hub is a basic networking device that simply forwards traffic; it cannot be used to configure VLANs.

This falls under the Networking domain in the CompTIA A+ Core 1 exam.


Question 5

A technician is connecting a hands-free car system via Bluetooth. Which of the following is a security feature that should be used for this task?



Answer : D

When connecting a Bluetooth device like a hands-free car system, using a PIN code adds a layer of security. The PIN code must be entered or confirmed during the pairing process to ensure that the connection is authorized and secure.

D . PIN code: Provides an additional security measure during Bluetooth pairing to prevent unauthorized access.

Why the other options are incorrect:

A . BitLocker: BitLocker is a drive encryption feature used to secure data on hard drives, not for securing Bluetooth connections.

B . Biometrics: Biometrics refers to authentication using physical traits like fingerprints, which are not typically used for Bluetooth connections.

C . TPM: Trusted Platform Module (TPM) is a hardware security feature used for encryption and secure boot processes, not for Bluetooth pairing.

This falls under the Mobile Devices and Security domain in the CompTIA A+ Core 1 exam.


Question 6

Which of the following is a legacy, 15-pin cable type?



Answer : C

VGA (Video Graphics Array) is a legacy 15-pin connector used for transmitting analog video signals. VGA was commonly used to connect monitors to computers, but it has been largely replaced by more modern digital interfaces like DVI and HDMI.

C . VGA: A legacy 15-pin connector used for analog video signals.

Why the other options are incorrect:

A . DisplayPort: DisplayPort is a newer digital interface and does not use a 15-pin connector.

B . DVI: DVI (Digital Visual Interface) is a digital connector used for video signals but does not have 15 pins.

D . HDMI: HDMI is also a digital interface for audio and video, but it uses a different connector with no 15 pins.

This topic relates to the Hardware domain in the CompTIA A+ Core 1 exam.


Question 7

Which of the following allows for a beam of light to transmit data through a flexible cable?



Answer : D

Single-mode fiber uses a beam of light to transmit data over long distances through a very thin, flexible cable. It is commonly used for high-speed data transmission across wide areas, such as between buildings or over long distances within a network. Single-mode fiber offers a higher bandwidth and longer distance capabilities compared to other types of fiber optics.

D . Single-mode fiber: Transmits data using light through a fiber optic cable, making it ideal for long-distance communication.

Why the other options are incorrect:

A . Coaxial: Coaxial cables use electrical signals, not light, to transmit data.

B . HDMI: HDMI (High-Definition Multimedia Interface) is used for transmitting audio and video signals but does not use light for data transmission.

C . Thunderbolt: Thunderbolt cables transmit data using electrical signals and are typically used for high-speed data transfer and display connections.

This falls under the Networking and Hardware domain in the CompTIA A+ Core 1 exam.
