Refer to the exhibit. Which two statements about the AAA configuration are true？（）
A.A good security practice is to havethe none parameter configured as the final method used toensure that no other authentication method will be used
B.If a TACACS+ server is not available， then a user connecting via the console port would not beable to gain access since no other authentication method has been defined
C.If a TACACS+ server is not available， then the user Bob could be able to enter privileged modeas long as the proper enable password is entered
D.Theaaa new-model command forces the router to override every other authentication methodpreviously configured for the router lines
E.To increase security， group radius should be used instead of group tacacs+
F.Two authentication options are prescribed by the displayedaaa authentication command
A.If the radius server returns an error， the enable password will be used
B.If the radius server returns a ’failed’ message， the enable password will be used
C.The command login authentication group will associate the AM authentication to a specifiedinterface
D.If the group database is unavailable， the radius server will be used
Authentication is the process of determining if a user or identity is who they claim to be. Refer tothe exhibit. Which statement about the authentication process is correct？（）
A.The LIST1 list will disable authentication on the console port
B.All login requests will be authenticated using the group tacacs+ method
C.The default login authentication will automatically be applied to all login connections
D.Because no method list is specified， the LIST1 list will not authenticate anyone on the consoleport
