NEW QUESTION 2

A technician needs to test a new USB headset for videoconference calls. Audio playback is working as expected, but sound from the microphone is not being recorded. The Device Manager and Sound settings show the microphone is installed. Which of the following should the technician do next?

• A. Examine the application and device mute controls.
• B. Connect the headset to a different USB port.
• C. Check the device's driver release date.
• D. Increase the speaker volume setting.

Answer: A

Explanation:
The correct answer is A. Examine the application and device mute controls. One of the possible reasons for the USB headset microphone not working is that the microphone is muted in the application or device settings. The technician should check if the mute button on the headset or the microphone icon in the application is active. If so, the technician should disable them and try to record sound again.
Some applications may also have their own settings for the microphone input. The technician should make sure that the USB headset is selected as the input device and that the volume level is appropriate. The technician can also test the microphone in different applications to see if the problem is specific to one application or not.
The other options are less likely to solve the problem, because:
•Connecting the headset to a different USB port may not make any difference if the device is already installed and recognized by the system.
•Checking the device’s driver release date may not be relevant if the microphone was working before and no updates were installed recently.
•Increasing the speaker volume setting may not affect the microphone input at all, and may only make the audio playback louder.

NEW QUESTION 4

A technician is working with a vendor to resolve an issue that a user reported. The vendor indicates that the technician's next step is to update the firmware. Which of the following is the most important step the technician should take before proceeding?

• A. Verify the device is fully charged and connected to a power supply.
• B. Ensure the device has adequate storage space for the update.
• C. Verify administrative access on the device.
• D. Export the users settings so they can be imported after the upgrade

Answer: A

Explanation:
The most important step the technician should take before proceeding is A. Verify the device is fully charged and connected to a power supply.
Firmware is a type of software that controls the basic functions and operations of a device, such as a router, printer, or scanner. Firmware can be updated to fix bugs, improve performance, or add new features to the device. However, updating firmware can also be risky, as it may cause the device to malfunction or become unusable if the update process is interrupted or corrupted.
One of the main causes of firmware update failure is power loss, which can occur if the device runs out of battery or is disconnected from the power source during the update. Power loss can damage the firmware and prevent the device from booting up or functioning properly. Therefore, it is essential to verify that the device is fully charged and connected to a power supply before updating the firmware. This can ensure that the device has enough power to complete the update process and avoid any interruptions or errors.
The other options are not as important as verifying the power status of the device. Ensuring the device has adequate storage space for the update is a good practice, but it is not likely to cause a major problem if the device does not have enough space. The update process will either fail to start or prompt the user to free up some space before proceeding. Verifying administrative access on the device is also a good practice, but it is not necessary for updating firmware. Administrative access is required for installing or uninstalling software applications, but not for updating firmware. Firmware updates are usually provided by the device manufacturer or vendor and do not require user authentication. Exporting the user settings so they can be imported after the upgrade is a precautionary measure, but it is not mandatory for updating firmware. Firmware updates do not usually affect the user settings or data on the device, unless they are incompatible or corrupted. Exporting the user settings can help restore them in case of any problems, but it does not prevent them from occurring.

NEW QUESTION 5

A technician is troubleshooting a PC that makes grinding noises and eventually shuts down. The technician determines the PC is overheating. Which of the following is most likely failing?

• A. RAM
• B. Motherboard
• C. SSD
• D. CPU fan

Answer: D

Explanation:
The most likely component that is failing and causing the PC to overheat is D. CPU fan. The CPU fan is a vital part of the cooling system that prevents the CPU from overheating by blowing air over the heatsink and dissipating the heat. If the CPU fan is faulty, noisy, or clogged with dust, it can reduce the airflow and cause the CPU temperature to rise12. This can result in poor performance, instability, or shutdowns of the PC.
The other components are less likely to be the cause of overheating. RAM, motherboard, and SSD do not generate as much heat as the CPU and usually do not require fans to cool them down1. They may overheat if there is poor ventilation in the case or if they are defective, but they are not as common as a failing CPU fan.
Therefore, the correct answer is D. CPU fan. This is the most likely component that is failing and causing the PC to overheat.

Answer: DF

Explanation:
The correct answers are D. The overall IT cost goes down and F. Upgrading applications is easier.
Application virtualization is a technology that allows users to run applications without installing them on their devices. The applications are stored and executed on a remote server, and the users can access them through a network connection. Application virtualization has several benefits, such as12:
•The overall IT cost goes down: Application virtualization reduces the need for hardware, software, and maintenance costs, as the applications are centralized and managed on the server side. This also saves energy and space, as fewer physical machines are required to run the applications. Additionally, application virtualization can reduce licensing costs, as the applications can be delivered on-demand and based on usage.
•Upgrading applications is easier: Application virtualization simplifies the process of updating and patching applications, as the changes can be made on the server side and pushed to the users instantly. This eliminates the need for manual installation and configuration on each device, and ensures that all users have the latest version of the applications.
Other benefits of application virtualization include123:
•Allows the running of legacy apps: Application virtualization can enable users to run
applications that are developed for older or incompatible operating systems, such as Windows 7 or XP. This can extend the lifespan of legacy applications and avoid compatibility issues.
•Enables cross-platform operations: Application virtualization can allow users to run applications that are designed for different platforms, such as Windows apps on iOS, Android, macOS, or Chrome OS. This can increase the accessibility and mobility of the applications and enhance the user experience.
•Improves security and compliance: Application virtualization can isolate the applications from the underlying operating system and hardware, preventing malware or unauthorized access from affecting them. This can also protect the data and settings of the applications from being tampered with or lost. Furthermore, application virtualization can help enforce compliance policies and regulations, as the applications can be controlled and monitored by the server.

NEW QUESTION 12

Which of the following allows several websites from different companies to be housed on the same virtual server?

• A. Rapid elasticity
• B. High availability
• C. Shared resources
• D. Metered utilization

Answer: C

Explanation:
Shared resources is the concept that allows several websites from different companies to be housed on the same virtual server. A virtual server is a software-based server that runs on a physical server and can host multiple virtual machines (VMs). Each VM can run a different operating system and application, such as a website, and have its own allocated resources, such as CPU, memory, disk space, and network bandwidth. However, the VMs share the underlying hardware resources of the physical server, which reduces the cost and complexity of maintaining separate servers for each website. This also enables rapid scalability, as new VMs can be created or deleted as needed.
One of the methods to host multiple websites on the same virtual server is to use virtual hosts. Virtual hosts are a feature of web servers, such as Apache, that allow the web server to serve different websites based on the domain name or IP address requested by the client. For example, a web server can host two websites, a.example.com and b.example.com, on the same virtual server and the same port (such as 80 or 443), by using virtual hosts to map each domain name to a different document root directory. The web server will then deliver the content of the corresponding website to the client based on the domain name in the HTTP request header.

• C. Replace the LED screen.
• D. Update the mobile device.

Answer: A

Explanation:
Calibrating the touch screen is the best action to resolve the issue of inaccurate touch input. Calibration adjusts the touch screen’s sensitivity and alignment to match the user’s touch. Resetting the mobile device could erase user data and settings and may not fix the touch screen issue. Replacing the LED screen or updating the mobile device are unnecessary and costly actions that may not solve the problem.

NEW QUESTION 14

Which of the following network devices should a technician install in order to isolate voice traffic on the network?

• A. Network tap
• B. Managed switch
• C. Hub
• D. DSL filter

Answer: B

Explanation:
A managed switch is a network device that can be configured to create VLANs (Virtual Local Area Networks), which are logical segments of a network that isolate traffic based on criteria such as function, security, or quality of service. A VLAN can be used to isolate voice traffic on the network, which can improve the performance and security of voice over IP (VoIP) applications. A network tap, a hub, and a DSL filter are not capable of creating VLANs.
