I dared to start a new thread after looking into questions and answers in the dump for 400-251 exam.
It is very frustrating to realize that those "solutions providers" sell us wrong answers to about a third of questions in the said exam. I saw them in the previous exam (350-018) which I failed because I didn't have a lot of time to study.
Feel free to participate and comment. Collective study is always effective.
So, here comes the first batch of my attempts to select better answers based on available documentation.
I'll provide links to support my selections where possible

C. A view is created on the Cisco IOS device to leverage role-based access controls.
