RADIUS can encrypt the entire packet that is sent to the NAS.F.RADIUS supports per-command authorization.Correct Answer:ABCSection: (none)ExplanationExplanation/Reference:Explanation:Two prominent security protocols used to control access into networks are Cisco TACACS+ and RADIUS. The RADIUS specification is described in RFC 2865leavingcisco.com, which obsoletes RFC 2138 leavingcisco.com. Cisco is committed to supporting both protocols with the best of class offerings. It is not theintention of Cisco to compete with RADIUS or influence users to use TACACS+. You should choose the solution that best meets your needs.
