Re: DO180 Ch06S02 quiz question

I guess the wrong bit in A is this : "is provisioned by the application developer."

Using Openshift, the storage resources are provisioned transparently to the application developers (ie, they don't need to log into an NFS server, create a share, etc), and thus B is more accurate. Openshift can also provision storage automatically, but that's a cluster administrator responsibility, and not an individual delopver's.
