You deploy an Azure Web App named ContosoApp. ContosoApp runs on five instances.
You need to run an application named App1.exe automatically as a background process for ContosoApp. The
solution must ensure that App1.exe runs in one instance only.
How should you deploy App1.exe?
A.
as a continuous web job
B.
in a new worker role instance
C.
as a scheduled web job
D.
as a virtual application

I think the answer would be continuous web job since it says it has to start automatically not under a schedule and in a continuous web job you can restrict the application to run in only one instance.
