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

You work as a network administrator at networkTut.com， study the exhibit carefully. The
configuration has been applied to router NET to mitigate the threat of certain types of ICMPbasedattacks while allowing some ICMP traffic to the corporate LAN to work. However， the configurationis incorrect. On the basis of the information in the exhibit， which configuration option wouldcorrectly configure router NET？（）
A.The first three statements of ACL 112 should have permitted the ICMP traffic and the laststatement should deny the identified traffic
B.The last statement of ACL 112 should have been "access-list 112deny icmp any 10.2.1.00.0.0.255"
C.The last statement of ACL 112 should have been "access-list 112permit icmp any 10.2.1.00.0.0.255"
D.ACL 112 should have been applied to interface Fa0/0 in an inbound direction
E.The last statement of ACL 112 should have been "access-list 112deny icmp any 10.1.1.00.0.0.255"
F.ACL 112 should have been applied to interface Fa0/1 in an outbound direction
G.None of the above
A.The dsl operating-mode auto command is required if the default mode has been changed
B.The ip mtu 1496 command must be applied on the dialer interface
C.The encapsulation ppp command is required
D.The ip mtu 1492 command must be applied on the dialer interface

C.On the ATM0/0 interface， add the dialer pool-member 1 command
D.On the ATM0/0 interface， add the dialer pool-member 0 command
