Final Answer:
The correct option to shut down and then restart a virtual machine (VM) using PowerShell is Shutdown-VM; Start-VM. Option C is the answer.
Step-by-step explanation:
The Shutdown-VM command is used to gracefully shut down a virtual machine, ensuring that all running processes are properly closed. After shutting down the VM, the Start-VM command is employed to restart it. This sequence of commands provides a controlled and orderly restart of the virtual machine.
Option 1 (Restart-Computer -Force) is a general computer restart command and may not be suitable for VMs. Option 2 (Stop-VM; Start-VM) directly stops and starts the VM without a proper shutdown. Option 4 (Restart-VM -Force) is a non-existent command for VM restart in PowerShell.
Option C is the answer.
