A system administrator is installing Hyper-V on a Windows Server 2016. They receive an error message. How can they solve the problem?

To successfully install Hyper-V on Windows Server 2016, it is essential to verify that the virtualization feature is enabled in the system's BIOS or UEFI settings. Hyper-V requires hardware virtualization capabilities, which are provided through the CPU's virtualization extensions, such as Intel VT-x or AMD-V. If this feature is not enabled, the Hyper-V installation will fail, and an error message will be generated.

Checking for the presence of virtualization capabilities is a critical first step in troubleshooting installation issues with Hyper-V. By ensuring this feature is enabled, the system administrator can resolve this potential restriction and proceed with the installation without further error messages.

Regarding the other options, while ensuring enough memory and checking the processor type are important factors for overall system performance and compatibility, they do not directly address the foundational requirement of having virtualization enabled. Additionally, confirming the essentials license is installed is relevant for licensing purposes but does not relate to the installation prerequisites required for enabling Hyper-V functionality.
