Two-factor authentication (2FA) significantly enhances security by requiring two forms of verification before granting access to company resources, making it harder for unauthorized users to gain access even if they have one of the credentials. PIN code enforcement adds an additional layer of security by ensuring that devices are protected by a PIN, making physical access to the device more challenging for unauthorized users. While the other options provide various benefits, 2FA and PIN code enforcement directly enhance the security of remote users accessing company resources.

If a user consistently receives an error requesting A4 paper for print jobs, and this issue is isolated to a single user, it's likely that the user's printer settings are configured incorrectly for A4 paper size instead of the standard letter size used in the office. Adjusting the printer defaults in the Control Panel on the user's computer to use letter-sized paper should resolve the issue without needing to reinstall drivers, switch printers, or require the user to check page size for every job.

Before creating a virtual machine (VM) on a computer, it's crucial to ensure that the CPU supports virtualization and that this feature is enabled in the BIOS (or UEFI) settings. While sufficient RAM and hard drive space are also important for running VMs effectively, and compatibility with the graphics card might be a consideration for VMs with intensive graphical requirements, the foundational step is to verify that the CPU supports virtualization and that this feature is activated in the BIOS settings. This is because virtualization technology, often referred to as VT-x (on Intel CPUs) or AMD-V (on AMD CPUs), is a prerequisite for running most virtualization software efficiently.
