Question #71
A technician assembled a new PC. After a few minutes, the computer slows down and then shuts itself off.
Which of the following is the most likely cause of the failure?
- A . Thermal paste was not used.
- B . The GPU needs additional power.
- C . The memory is insufficient.
- D . The motherboard is incompatible.
Correct Answer: A
A
Explanation:
The most likely cause of the failure is
A) Thermal paste was not used.
Thermal paste, also known as thermal grease or thermal compound, is a substance that is applied between the CPU and the heat sink to improve the heat transfer and cooling of the CPU. Thermal paste fills the gaps and irregularities between the CPU and the heat sink, creating a better contact and reducing the thermal resistance.
According to some web search results, some signs and symptoms of not using thermal paste or using it incorrectly are:
• The CPU overheats and slows down or shuts down to prevent damage
• The CPU fan spins faster and louder to try to cool down the CPU
• The PC performance drops or becomes unstable
• The PC crashes or displays errors or blue screens
To fix this issue, the technician should apply thermal paste properly between the CPU and the heat sink, following these steps:
• Turn off the PC and unplug it from the power source
• Open the PC case and locate the CPU fan and heat sink
• Remove the CPU fan and heat sink from the motherboard
• Clean the surfaces of the CPU and heat sink with a lint-free cloth and alcohol
• Apply a small amount of thermal paste (about the size of a grain of rice) in the center of the CPU
• Reattach the heat sink and CPU fan to the motherboard, making sure they are aligned and secured
• Close the PC case and plug it back to the power source
The GPU needs additional power, the memory is insufficient, or the motherboard is incompatible are not likely causes of the failure, since they would not cause the PC to overheat and shut down after a few minutes. The GPU needs additional power if it has a high power consumption that exceeds the capacity of the power supply or the PCIe slot. The memory is insufficient if it cannot handle the applications or tasks that are running on the PC. The motherboard is incompatible if it does not support the CPU, RAM, or other components that are installed on it. These issues may cause poor performance, errors, or crashes, but not overheating and shutting down.

Question #72
After a corporate office upgraded its Ethernet wiring, a number of users are unable to access the internet. A technician establishes a theory for troubleshooting the issue and tests it, but the theory is incorrect.
Which of the following should the technician do next?
- A . Document the findings.
- B . Gather additional details.
- C . Escalate the problem.
- D . Identify user changes.
Correct Answer: B
B
Explanation:
The correct answer is B. Gather additional details.
According to the CompTIA troubleshooting process for the A+ certification exams1, the technician should gather additional details after testing a theory that is incorrect. This step helps to identify the problem more accurately and establish a new theory of probable cause. The other options are not appropriate for this stage of the troubleshooting process. Documenting the findings, escalating the problem, and identifying user changes are steps that should be done later in the process, after determining the cause and implementing a solution1.

Question #73
A user is experiencing a log-on issue when attempting to use a network-authenticated application in a corporate environment The technician successfully resolves the issue by resetting the password The user confirms that everything is working as expected.
Which of the following steps should the technician take next?
- A . Refer to the vendor’s instructions
- B . Establish a plan of action
- C . Document the findings
- D . Implement preventative measures
Correct Answer: C
C
Explanation:
After resolving an issue, it’s crucial for a technician to document the findings, actions taken, and the outcome. This documentation serves several purposes: it provides a record of the problem and the solution for future reference, which can be helpful if the issue recurs or if similar problems arise with other users. It also ensures that any follow-up actions, if necessary, are well-informed by the history of the issue. Documenting the resolution process contributes to knowledge sharing among the support team and can improve the efficiency of future troubleshooting efforts.

Question #74
A user requested upgrades to a company-issued laptop to increase its performance while working with a large database stored on drive C.
Which of the following tasks should a systems administrator complete to BEST meet this goal? (Select TWO).
- A . Configure RAID 1.
- B . Install a hybrid drive.
- C . Upgrade to 1GB NIC.
- D . Increase the RAM.
- E . Migrate to a SSD.
- F . Upgrade the power supply.
Correct Answer: D,E
D,E
Explanation:
To increase the performance of a laptop working with a large database stored on drive C, a systems administrator should increase the RAM and migrate to an SSD. Increasing the RAM will help the laptop to better handle the large database, while migrating to an SSD will improve the speed at which the laptop can access the database. Configuring RAID 1, installing a hybrid drive, upgrading to a 1GB NIC, and upgrading the power supply will not directly improve the laptop’s performance when working with a large database.

Question #75
Which of the following would be BEST reason to use a virtual machine as a sandbox?
- A . To test new software in a safe environment
- B . To increase the efficient use of computing resources
- C . To run multiple machines on the same hardware
- D . To have dedicated hardware for a single system
Correct Answer: A
A
Explanation:
The main reason to use a virtual machine as a sandbox is to test new software in a safe environment without risking the integrity of the host operating system. Using a virtual machine enables the testing of software and allows for the isolation of the software from the host system. References: CompTIA A+ Certification Study Guide, Tenth Edition, pg. 409

- A . DHCP
- B . LDAP
- C . UTM
- D . DNS
Correct Answer: A
A
Explanation:
Dynamic Host Configuration Protocol (DHCP) allows a networked device to always be assigned the same IP address based on the device’s MAC address. DHCP can also assign other network configuration settings to devices automatically.

Question #77
An IT technician is working on a help desk ticket concerning a user’s inability to create a virtual machine. The technician has already checked the RAM and HDD space in the user’s machine .
Which of the following settings should the technician check NEXT to help troubleshoot the issue?
- A . BitLocker
- B . MSConfig
- C . BIOS
- D . Secure Boot
Correct Answer: C
C
Explanation:
One of the possible settings that could prevent a user from creating a virtual machine is BIOS (Basic Input/Output System). BIOS is a firmware that controls how hardware components interact with each other and with software applications. Some BIOS settings may need to be changed or enabled to allow virtualization, such as VT-x (Intel Virtualization Technology) or AMD-V (AMD Virtualization). The other options are not related to virtualization settings. Verified References: [How To Enable Virtualization In BIOS Settings].
