Write a standard access list to block Rodney and Carol’s computer from sending information<br />
to Jim’s computer; but will allow all other traffic from the 204.90.30.0 network. Block all other<br />
traffic. Keep in mind that there may be multiple ways many of the individual statements in an<br />
ACL can be written.<br />
Place the access list at:<br />
Router Name: ___________________________<br />
