The correct answer is A. Amount of system RAM. A Type 2 hypervisor is a virtualization software that runs on top of a host operating system, which means it shares the system resources with the host OS and other applications. Therefore, increasing the amount of system RAM can improve the performance of the hypervisor and the virtual machines running on it. RAM is used to store data and instructions that are frequently accessed by the CPU, and having more RAM can reduce the need for swapping data to and from the storage device, which is slower than RAM.

NIC performance, storage IOPS, and dedicated GPU are not as relevant for improving the hypervisor’s performance in this scenario. NIC performance refers to the speed and quality of the network interface card, which is used to connect the computer to a network. Storage IOPS refers to the number of input/output operations per second that can be performed by the storage device, which is a measure of its speed and efficiency. Dedicated GPU refers to a separate graphics processing unit that can handle complex graphics tasks, such as gaming or video editing. These components may affect other aspects of the computer’s performance, but they are not directly related to the hypervisor’s ability to compile new source code.

Booting into safe mode and performing a malware scan are the steps that a technician should perform when troubleshooting an issue with pop-up advertising messages on a PC. Safe mode is a diagnostic mode that starts the PC with minimal drivers and services, which can prevent the pop-up malware from running. Malware scan is a tool that can detect and remove the pop-up malware, as well as prevent further infection or damage. Investigating how the malware was installed, reinstalling the browser and restarting the machine are possible steps that can be done after booting into safe mode and performing a malware scan, depending on the situation and the results of the scan.

The correct answer is D. Unattended installation. An unattended installation is a way of installing Windows 10 without requiring any user input or interaction. It uses a configuration file called answer file that contains the settings and preferences for the installation, such as the product key, language, partition, and network settings. An unattended installation can be performed by using a bootable USB flash drive or DVD that contains the Windows 10 installation files and the answer file1. This is the fastest way for the technician to install Windows 10 on a newly built computer, as it automates the whole process and saves time.

A factory reset is a way of restoring a computer to its original state by deleting all the data and applications and reinstalling the operating system. A factory reset can be performed by using the recovery partition or media that came with the computer, or by using the Reset this PC option in Windows 10 settings2. A factory reset is not a way of installing Windows 10 on a newly built computer, as it requires an existing operating system to be present.

A system restore is a way of undoing changes to a computer’s system files and settings by using a restore point that was created earlier. A system restore can be performed by using the System Restore option in Windows 10 settings or by using the Advanced Startup Options menu3. A system restore is not a way of installing Windows 10 on a newly built computer, as it requires an existing operating system and restore points to be present.

An in-place upgrade is a way of upgrading an existing operating system to a newer version without losing any data or applications. An in-place upgrade can be performed by using the Windows 10 Media Creation Tool or by running the Setup.exe file from the Windows 10 installation media. An in-place upgrade is not a way of installing Windows 10 on a newly built computer, as it requires an existing operating system to be present.

Update and Security is the section in Windows 10 Settings that allows the user to back up their device. Backing up a device means creating a copy of the data and settings on the device and storing it in another location, such as an external drive or a cloud service. Backing up a device can help the user restore their data and settings in case of data loss, corruption, or theft. Devices and Printers, Email and Accounts, and Apps and Features are not sections in Windows 10 Settings that allow the user to back up their device.

The most effective way to check other machines on the network for this unknown threat is to manually check each machine. This can help to identify any other machines that may be infected with the unknown virus and allow them to be cleaned.

The technician should use dfrgui.exe to defragment the hard drive1

Using disk-wiping software is the most secure method for removing information from past users’ hard drives in order to reuse the hard drives. Disk-wiping software can help to ensure that all data on the hard drive is completely erased and cannot be recovered.

A keylogger is a type of malware that records the keystrokes of a user and sends them to a remote attacker. A keylogger can be used to steal passwords, credit card numbers, personal information, and other sensitive data. A keylogger can be delivered through a USB drive that contains a malicious executable file, such as grabber.exe, and an output file that stores the captured keystrokes, such as output.txt. The other options are not likely to use this method of attack.
