Explanation
B is correct because the presence of logging output for the ACL confirms that the 'log' or 'log-input' keyword was added to the access list entry, enabling logging. D is correct because the 'ip access-list logging hash-generation' command causes IOS to include a hash value in ACL log messages; this hash is used to detect and suppress duplicate log entries, and its presence in the output confirms the feature is enabled. The other options are not supported: A cannot be confirmed without verifying the exact hex value against the packet count; C requires seeing a 'deny' action in the ACL entry; and E cannot be determined from ACL log output alone.
