Question 1

When a user powers on a computer, the fans start, but the machine does not POST. Which of the following is the first step a technician should take to troubleshoot this issue?



Answer : A

Testing the power supply first ensures that the correct voltage is reaching all components, which is a common cause of boot issues. Modifying BIOS settings is not possible without a POST. Checking PCIe cards or replacing the motherboard are secondary steps if the power supply is functional. CompTIA A+ Core 1 objectives cover power supply testing as an essential troubleshooting step in system startup issues.


Question 2

A technician has just installed a new SSD into a computer, but the drive is not appearing. Which of the following is most likely the reason's?



Answer : D

Improper seating is the most common reason an SSD isn't recognized. Ensuring it is correctly connected resolves the issue.

Why Not A (Faulty SSD): A faulty SSD is possible but less likely than an installation issue.

Why Not B (Not formatted): Formatting affects data usability, not drive detection.

Why Not C (Incompatibility): SSD compatibility issues are rare with modern hardware.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 3.3, storage troubleshooting.


Question 3

A user creates a support ticket to report a conference room projector that does not work. The user says that even though the provided cables are being used, the projector screen shows the following error message:

No signal input

Which of the following describes the FIRST action that should be taken?



Answer : D

The most common reasons you may be seeing the 'No Signal' message: The projector and the source device are not connected correctly.

The first action should be to check the video cable and replace it if necessary, as the error message suggests that the projector is not receiving a signal from the laptop. Verifying that the projector is turned on and checking the bulb would come after verifying the video cable.


Question 4

A technician is troubleshooting stylus issues on identical, company-provided tablets. Users can purchase their own accessories. Some users have no issues, but others report that their styluses charge intermittently and die frequently. Which of the following is the most likely cause of this issue?



Answer : A

Comprehensive and Detailed In-Depth

The most likely cause is third-party or ill-fitting cases obstructing the contact between the stylus and the tablet charging mechanism. Some cases may not be designed with stylus charging in mind, particularly if users are purchasing their own accessories.

Option B: A software update might fix OS-related issues, but would not typically affect physical charging.

Option C: If some devices had defects, the issue would likely be consistent, not isolated to some users.

Option D: Firmware issues could be a factor but are less likely than physical obstructions when users are using different accessories.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.4: Given a scenario, configure settings and use cases for laptops and mobile devices.


Question 5

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 6

A user experiences a random BSOD while using a computer, but the operating system recovers as expected Which of the following symptoms would indicate the issue is related to RAM?



Answer : D

D . POST Code Beeps:

During the Power-On Self-Test (POST), the BIOS performs checks on system hardware, including RAM. If the RAM is faulty, POST may produce a series of beep codes indicating memory issues.

These beep codes are often the first sign of RAM-related problems, especially if the BSOD occurs randomly.

Incorrect Options:

A . Wrong BIOS configurations: Incorrect BIOS settings may cause boot errors, but they are less likely to cause random BSODs.

B . Continuous reboots: Continuous reboots could result from multiple hardware or software issues but do not specifically point to RAM.

C . Distended capacitors: Faulty capacitors typically affect the motherboard, not the RAM.

Key Takeaway: POST beep codes are a common diagnostic tool for identifying RAM-related issues.


Question 7

A user wants to create a VM on a computer. Which of the following should the user check first?



Answer : C

Before creating a virtual machine (VM) on a computer, it's crucial to ensure that the CPU supports virtualization and that this feature is enabled in the BIOS (or UEFI) settings. While sufficient RAM and hard drive space are also important for running VMs effectively, and compatibility with the graphics card might be a consideration for VMs with intensive graphical requirements, the foundational step is to verify that the CPU supports virtualization and that this feature is activated in the BIOS settings. This is because virtualization technology, often referred to as VT-x (on Intel CPUs) or AMD-V (on AMD CPUs), is a prerequisite for running most virtualization software efficiently.
