A laptop does not have any audio output from the built-in speakers. The Windows Device Manager shows a down arrow for the audio device.
Which of the following will correct this audio issue?
- A . Replacing the speakers
- B . Increasing the volume
- C . Enabling the audio device
- D . Updating the driver
C
Explanation:
Enabling the audio device is the correct action to correct an audio issue where a laptop does not have any audio output from the built-in speakers and Windows Device Manager shows a down arrow for the audio device. A down arrow indicates that the audio device is disabled and needs to be enabled by right-clicking on it and selecting Enable device. Replacing the speakers, increasing the volume, or updating the driver are unlikely to solve the issue if the audio device is disabled.
A customer recently installed a new graphics card, but the card’s HDMI port is not getting a signal when connected to the monitor. When the monitor is connected to the original HDMI port, located next to the USB ports, everything works as expected.
Which of the following should the technician do next?
- A . Change the input source selection on the monitor.
- B . Check to see whether the UEFI setting for PCle graphics is enabled.
- C . Install a higher wattage power supply.
- D . Test the new graphics card with an HDMI to DVI adapter.

Explanation:
A technician is diagnosing a workstation that shuts down unexpectedly during a butn-in test.
Which of the following is the MOST likely cause for this symptom?
- A . Faulty CMOS battery
- B . OS update issue
- C . Overheating
- D . Faulty RAM
C
Explanation:
If a workstation shuts down unexpectedly during a burn-in test, overheating is the most likely cause. This is because a burn-in test is designed to stress the components of the workstation, which can generate a lot of heat. Therefore, overheating is the correct answer.

Which of the following DNS record types is used to direct email to a mail server?
- A . CNAME
- B . SRV
- C . MX
- D . SOA
C
Explanation:
An MX (Mail Exchange) record specifies the mail server responsible for receiving email for a domain.
Why Not A (CNAME): CNAME is used for domain aliasing, not for email delivery.
Why Not B (SRV): SRV records are used to locate specific services, not mail servers.
Why Not D (SOA): SOA records provide domain information but do not handle email.

A company needs to support a 10Gbps throughput.
Which of the following is the MINIMUM cable category that could be used?
- A . Cat 5
- B . Cat 5e
- C . Cat 6
- D . Cat 6a
D
Explanation:
The minimum cable category that could be used to support a 10Gbps throughput is Cat 6a. Cat 6a cable is required with 10 Gigabit Ethernet for reliable performance with cable lengths up to 100 metres. However, lower-specification cables can often be successfully used, particularly with the shorter cable lengths required in a typical home123.
A user uploads a file to a storage location that is accessible via a web browser and a client application. The user’s coworkers can access the file as well. The service that the file is stored with is provided by a third party for a monthly fee. The third party’s service is available to any business or consumer who would like to use the service.
Which of the following BEST describes the type of service that is in use?
- A . Hybrid cloud
- B . Infrastructure as a service
- C . Public cloud
- D . Private cloud
C
Explanation:
A public cloud is a cloud computing model that provides services and resources to anyone over the internet. The service that the user uploads a file to is an example of a public cloud service, as it is accessible via a web browser and a client application, allows multiple users to access the file, and is provided by a third party for a monthly fee. A hybrid cloud is a combination of public and private cloud services that share data and resources. Infrastructure as a service is a cloud computing model that provides servers, storage, networking, and software over the internet. Private cloud is a cloud computing model that provides services and resources to a specific organization or group over a private network
A customer calls the help desk to report a problem connecting to a shared drive on a server. The technician determines that the user’s server credentials have expired and reactivates them.
Which of the following should the technician do next?
- A . Escalate the issue.
- B . Document the findings.
- C . Perform backups of all critical data.
- D . Verify system functionality.
D
Explanation:
After resolving the immediate issue (reactivating server credentials), verifying system functionality ensures the solution works as intended and the user can now access the shared drive. This step is a part of the CompTIA troubleshooting methodology: Identify the problem.
Establish a theory of probable cause.
Test the theory to determine the cause.
Establish a plan of action.
Implement the solution.
Verify full system functionality.
Document findings, actions, and outcomes.
Why Not B (Document the findings): Documentation comes after verifying the system works.
Why Not A (Escalate the issue): Escalation is unnecessary since the problem was resolved.
Why Not C (Perform backups): Performing backups is unrelated to verifying credential functionality.

A technician powers on a PC and its monitor and sees the following error message:
No input signal detected
The display lights on the computer are on.
Which of the following is a possible solution?
- A . Changing the BIOS settings
- B . Changing the connector setting on the monitor
- C . Checking the power plug on the monitor
- D . Checking the power plug on the PC
B
Explanation:
Changing the connector setting on the monitor is a possible solution for a PC and its monitor that display the error message "No input signal detected". This error can be caused by an incorrect input selected on the monitor, so changing the connector setting to the correct input should resolve the issue.

A user failed to gain access to a building’s entrance after security measures at the entrance were upgraded last week. The company implemented the 13.56MHz frequency short band, and users can now utilize their mobile devices to authenticate.
Which of the following has to be enabled for the mobile device to authenticate?
- A . Bluetooth
- B . Biometrics
- C . NFC
- D . PIN
C
Explanation:
NFC (Near Field Communication) is a technology used for short-range wireless communication between devices, typically used for contactless payments and authentication. In this scenario, the 13.56MHz frequency short band was implemented, and users can authenticate using their mobile devices, which requires NFC to be enabled on the device.
