AI explanation

A standard access list can only filter based on source IP address, not on protocol or port, so access-list 1 deny 172.16.16.16 blocks all traffic sourced from that host out the interface — which includes the TFTP traffic in question. The other extended-ACL-style options mix syntax incorrectly (e.g., stray numbers, mismatched keywords), making them invalid Cisco IOS commands.
