If the answer isn't 'All of the above,' I'm going to have a serious case of control plane pain.

I heard the test proctors are going to dress up as network controllers during the exam, just to keep us on our toes. Better bring my controller costume just in case!

D) controller clustering makes the most sense to me. Achieving fast failover and improving connectivity sounds like it requires a clustered control plane architecture.
