thick-provision

Question 11

The _____ ______ panel enables you to set a delay between the time when a virtual machine is turned on and the guest operating system starts to boot.

Answer 11

Boot Delay

*A delayed boot can help stagger virtual machine startups when several virtual machines are being powered on.
