CompTIA Server+ SK0-005 Practice Question

A data-center technician reports that a rack-mounted server at a distant colocation facility will not boot because the OS disk is corrupt. The site is unstaffed outside business hours, and corporate policy forbids attaching any physical media to the server. The only reachable interface is the server's dedicated BMC port on a separate management VLAN. The administrator must boot a Windows Server ISO that resides on their notebook and reinstall the OS without travelling to the site. Which out-of-band management feature should the administrator use to make the ISO appear as a local DVD drive during POST?
