Network Topology Exhibit：
Configuration Exhibit：
NET（config）# access-list 112 deny icmp any any echo log
NET（config）# access-list 112 deny imp any any redirect log
NET（config）# access-list 112 deny icmp any any mask-request log
NET（config）# access-list 112 permit icmp any 10.1.1.0 0.0.0.255
NET（config）# interface Fa0/1
NET（config-if）# ip access-group 112 in
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
