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].

ECC stands for Error Correction Code, which is a type of memory that can detect and correct data errors that may occur during processing or transmission. ECC memory is commonly used in servers that handle sensitive or critical information, such as payment information online, because it can reduce the risk of data corruption, system crashes, or security breaches12.

DDR4 is a generation of DDR technology, which stands for Double Data Rate. DDR4 memory is faster and more power-efficient than its predecessors, but it does not necessarily have ECC functionality. DDR4 memory can be either ECC or non-ECC1.

VRAM is Video RAM, which is a type of memory that is dedicated to storing graphics data for display. VRAM is usually found on graphics cards or integrated graphics processors, not on servers3.

SODIMM is Small Outline DIMM, which is a type of memory module that has a smaller size and lower profile than regular DIMMs. SODIMMs are typically used in laptops, notebooks, or other compact devices, not on servers3.

The technician should research the requirements of the CAD program to see if the computer meets them or needs any upgrades or updates to run it properly. The technician should also check the Event Viewer logs to see if there are any errors or warnings related to the application or system performance that could indicate the cause of the problem or suggest a solution.

The best option to allow all users to print to the new network printer is to install all applicable print drivers on the print server. This way, the print server can automatically provide the correct driver to the client computers when they connect to the printer. This option also reduces the administrative overhead and security risks of the other options, which involve either granting users more privileges, mapping them to a shared folder, or remotely accessing their computers.

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.

The digitizer is the component that enables input on a mobile device's touch screen. It is a transparent layer that sits over the screen and detects the location of touch inputs. OLED (Organic Light Emitting Diode) is a type of display technology. Inverter is a component used in older LCD displays to provide power to the backlight. CMOS (Complementary Metal-Oxide-Semiconductor) sensor is a type of image sensor used in digital cameras and smartphones to capture images.

When a phone's battery overheats and expands, it poses a significant safety risk, including the potential for fire or the battery bursting. The first and most critical action is to turn off the device to prevent further chemical reactions within the battery that could exacerbate the situation. Turning off the phone halts its operations, minimizing the heat generation and reducing the risk of further damage or danger. This is a precautionary measure to ensure the user's safety and to prevent any additional harm to the phone itself. It's important for the user to not attempt to charge or use the phone in this condition and to seek professional help or replacement of the battery or device as needed.References: Mobile Devices 1101.docx, Safety and Environmental Concerns section.

The correct answer is D. Identify the problem.

The first troubleshooting step that the technician should perform is to identify the problem. This means that the technician should gather information from the user and the system, and analyze the symptoms and the error messages to determine the nature and the scope of the issue. Identifying the problem can help to define the expected outcome, establish a theory of probable cause, and plan a course of action.

The other options are not the first troubleshooting steps, but they are part of the troubleshooting process that should be performed after identifying the problem. Establishing a plan of action (option A) means that the technician should devise a strategy to resolve the issue, based on the theory of probable cause and the available resources. Testing the theory (option C) means that the technician should verify if the theory of probable cause is correct, by performing tests or experiments on the system or its components. Documenting the findings (option B) means that the technician should record and report the results of each troubleshooting step, as well as the final solution and outcome.
