You run a Windows Server 2022 Hyper-V host. You need a lab VM (LabHost) to run Docker Windows containers with Hyper-V isolation and also host nested VMs for testing. What must you do on LabHost’s configuration before installing the Hyper-V role inside it? (Choose two)

Correct answer: Disable dynamic memory and assign LabHost a fixed amount of memory., Expose virtualization extensions to LabHost’s guest by setting ExposeVirtualizationExtensions to True..
Why this is the answer
To run nested virtualization, which is required for Hyper-V inside a VM, you must expose virtualization extensions to the guest VM. This is done by setting the ExposeVirtualizationExtensions property to True using PowerShell. Additionally, nested virtualization does not support dynamic memory. Therefore, you must disable dynamic memory for LabHost and assign it a fixed amount of memory to ensure stable operation. Enabling processor compatibility mode is generally used for live migration between hosts with different CPU architectures and is not a requirement for nested virtualization. Enabling SR-IOV on LabHost's network adapter is for direct hardware access to the network adapter from the VM, not for nested virtualization. Converting LabHost to Generation 1 is unnecessary; Generation 2 VMs fully support nested virtualization.
