The transcode.exe utility activates its license online when it is installed. You need to ensure that the registration of the transcode utility is handled as specified in its license. Which method should you add to the TranscodeWorkerRole class?
Correct answer is D.
A variable named license contains the license key. The license for the transcoding utility requires that it be unregistered when it is not in use.
Process.Start (String) – starts a process resource by specifying the name of a document or application file and associates the resource with a new Process

Process.WaitForExit() Instructs the Process component to wait indefinitely for the associated process to exit.

you can discard 'a' because var.hasExited, 'c' because is not waiting for the process to end and 'b' because i think that syntax should be use when the role instance will be stopped, but i think its not the case here
