Refer to the exhibit. An engineer implemented an access list on R1 to allow anyone to Telnet except R2 Loopback0 to R1 Loopback4. How must sequence 20 be replaced on the R1 access list to resolve the issue?

The correct sequence to deny traffic from R2 Loopback0 to R1 Loopback4 while allowing other Telnet traffic should specify R2 Loopback0 as the source and R1 Loopback4 as the destination. Therefore, the original entry 'sequence 20 deny tcp host 100:ABC:2011:7 host 400A:0:400C::1 eq telnet' needs to be corrected. Option D correctly denies TCP traffic from the source address '1001:ABC:2011:7::1' (R2 Loopback0) to the destination address '400A:0:400C::1' (R1 Loopback4) on port 23 (Telnet).
Agree with solution "D". source ipv6 address needs to be corrected to "1001:ABC:2011:7::1". The "deny" statement is required.
D is corerct
