First, we should observe that the question is not grammatically correct. Thus, we cannot know the intent of the question. Perhaps the question wants to know which RADIUS functions are supported on a Cisco router (Authentication and Authorization are, but Accounting is not). Perhaps the writer of the question wanted to know which functions RADIUS supports and, in a bit of trickery, sees Authentication and Authorization only as Authentication (because RADIUS combines Authentication and Authorization ), and so the correct answer is Authentication (Authorization being included) and Accounting.
Due to the lack of a correct and complete question, and without knowing the thoughts of the writer of this question, it is impossible to determine the answer the author has deemed to be correct.
