Recovery mode is a special boot option that allows the user to access advanced tools and features to troubleshoot and remove malware from the device. Recovery mode can also restore the system to a previous state or reset the device to factory settings. Running System Restore, scheduling a scan, or restarting the PC may not be effective in removing the malware, as it may still be active or hidden in the system files.

Comprehensive and Detailed In-Depth Explanation:
Many modern laptops have both an integrated GPU (built into the CPU) and a dedicated GPU (such as NVIDIA or AMD). The system may default to the integrated GPU to save power, which results in poor gaming performance. The technician should manually set the game to use the dedicated graphics card to resolve the issue.
* A. Overclock the RAM - Incorrect. While overclocking RAM can improve performance slightly, it does not resolve GPU-related gaming lag.
* B. Enable NIC teaming - Incorrect. NIC teaming improves network bandwidth and has no effect on gaming graphics.
* D. Activate CPU hyperthreading - Incorrect. Hyperthreading improves multitasking but does not directly impact gaming graphics performance.

When an employee is unable to access the company portal using a VPN on their personal smartphone, the most likely cause is:
* The smartphone is not enrolled in MDM service:Mobile Device Management (MDM) services often control access to company resources. If the smartphone is not enrolled, it may be blocked from accessing the VPN and, consequently, the company portal.
* The application must be purchased by the company:Unlikely, as most VPN applications are free to download or included in the company's software package.
* The smartphone is not on the latest OS version:While this could cause compatibility issues, it is less likely than the MDM enrollment issue.
* The application fails to install and launch:This would be a different problem and would usually present specific error messages.
