PC-2 failed to establish a Telnet connection to the terminal server .
Which configuration resolves the issue?
- A . 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 - B . 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 - C . Gateway-Router(config)#fipv6 access-list Default Access
Gateway-Router(confia-ipv6-acl)#sequence 25 permit tcp host 2018:DB1:A:B:2 host 2018:DB1:A: - D . :1 eq telnet
- E . 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: - F . :1 eq telnet
Suggested Answer: D
Explanation:
In fact in this question both answer A and answer C are correct but we believe answer A is the better choice as it only allows PC-2 to telnet to terminal server. All other hosts are refused to telnet to terminal server via sequence 20.
