Which IPv6 ACL command will permit traffic from any host to an SMTP server on network 2001:DB8:10:10::/64?

  • permit tcp any host 2001:DB8:10:10::100 eq 25
  • permit tcp host 2001:DB8:10:10::100 any eq 25
  • permit tcp any host 2001:DB8:10:10::100 eq 23
  • permit tcp host 2001:DB8:10:10::100 any eq 23

Explanation: To permit traffic to an SMTP server, the ACL must match the destination port 25 (the standard port for SMTP). The command permit tcp any host 2001:DB8:10:10::100 eq 25 correctly identifies the source as "any" host, the destination as the specific server IP on the target network, and specifies the correct protocol (TCP) and port number (25). Port 23 is used for Telnet, not SMTP.
