The permit statement specifies an incorrect wildcard mask.
The sequence of the ACEs is incorrect.
The established keyword is not specified.

The port number for the traffic has not been identified with the eq keyword.

Answers Explanation & Hints:

When verifying an ACL, the statements are always listed in a sequential order. Even though there is an explicit permit for the traffic that is sourced from network 172.31.1.0 /24, it is being denied due to the previously implemented ACE of CiscoVille(config)# access-list 9 deny 172.31.0.0 0.0.255.255 . The sequence of the ACEs must be modified to permit the specific traffic that is sourced from network 172.31.1.0 /24 and then to deny 172.31.0.0 /16.
