Refer to the exhibit. PC-2 failed to establish a Telnet connection to the Terminal Server. Which solution allows PC-2 to establish the Telnet connection?

A. Gateway-Router(config)#ipv6 access-list Default_Access
Gateway-Router(config-ipv6-acl)#no sequence 20
Gateway-Router(config-ipv6-acl)#sequence 5 permit tcp host 2018:DB1:A:B::2 host 2018:DB1:A:C::1 eq telnet
B. Gateway-Router(config)#ipv6 access-list Default_Access
Gateway-Router(config-ipv6-acl)#permit tcp host 2018:DB1:A:B::2 host 2018:DB1:A:C::1 eq telnet
C. Gateway-Router(config)#ipv6 access-list Default_Access
Gateway-Router(config-ipv6-acl)#sequence 15 permit tcp host 2018:DB1:A:B::2 host 2018:DB1:A:C::1 eq telnet
D. Gateway-Router(config)#ipv6 access-list Default_Access
Gateway-Router(config-ipv6-acl)#sequence 25 permit tcp host 2018:DB1:A:B::2 host 2018:DB1:A:C::1 eq telnet

    1. C is correct, becauce ACL 20 will denied telnet toward terminal server, you have to setup sequece before 20, because by default you get ACL with sequence number 50 (incerease number +10 as was last ACL)

    2. because seqence 20 is denying it and acl stop at first match. You have to inject permitting line in front of it therefore – C is correct as solution.

      If B is applied it would appear as sequence 50 and that solves nothing….
