Which one of the following is NOT correct about the firmware settings of a generation 2 VM?

In the context of generation 2 virtual machines (VMs), it's important to understand that they utilize UEFI (Unified Extensible Firmware Interface) as their firmware, which introduces several enhancements and features compared to legacy BIOS-based systems. Among these features, the ability to set the boot order is one of them.

While generation 1 VMs only support BIOS firmware and have more limitations around boot management, generation 2 VMs expand on this by enabling alterations to the boot order. Therefore, stating that you cannot set the boot order on a generation 2 VM is incorrect, as it can actually be configured.

The other statements highlight valid functionalities of generation 2 VMs. For example, Secure Boot can be enabled to protect the system from threats during the boot process, UEFI firmware is indeed in use, and boot diagnostics can be configured to monitor the boot process and troubleshoot issues effectively. Each of these features showcases the advancements and greater control provided by generation 2 VMs over their predecessors.
