Access Control List
V 4.0 March 2008

            How are the lines of an Access Control List
            evaluated?
            Using the following diagram, create a standard
            ACL that will deny traffic from 210.93.105.4
            to the 192.5.5.0 network but will allow traffic
            from all other hosts:




            In the wildcard mask of an Access Control List,
            the “0” means what? The “1” means what?
            In an Access Control List, the wildcard mask of
            255.255.255.255 can be substituted using what
            word?
            What information does the command “show
            access list” display?
            Create an Extended ACL to prevent host
            210.93.105.50 from accessing an FTP server
            located at 192.5.5.148




            What are the four parameters that a Standard
            or Extended ACL (Named or Numbered) can
            use to filter data traffic?
            What numbers define a Standard IP ACL?
            What numbers define an Extended IP ACL?
            IPX?
            Why use Access Control Lists?
            In an Access Control List, the wildcard mask of
            0.0.0.0 can be substituted using what word?
            What is the rule concerning the number of ACL
            control list that can be placed on a port for each
            of the routing protocols?

            Which of the following commands would be
            used to correctly configure a standard ACL?

            A. Router# access-list 10 permit any
            B. Router# access-list 10 permit host any
            C. Router(config)# access-list 10 permit any
            D. Router(config)# access-list 10 permit any
            any

             E. Router(config-access-list)# access-list 10
            permit any
            Assuming it is correctly applied on the proper
            interface, what affect will the following ACL have
            on network traffic?

            access-list 142 deny tcp 172.16.0.0 0.0.255.255
            any eq 80
            access-list 142 permit ip any any
            Describe how the wildcard mask of 0.0.0.15 will
            affect network traffic:

            As an ACL is evaluated, what happens when a
            parameter on the list matches an input?
            How would you remove an ACL?
                - Standard
                - Extended
                - Named
            Under what circumstance would the creation of
            an ACL have immediate affect on the network?
            access-list 199 deny tcp host 192.168.43.6 any
            eq 23

            Assuming the access list is correctly applied to
            an interface, what effect will this ACL have on
            network traffic?
            What is a “firewall router” and how are Access
            Control List used on them?
            What ACL related information does the
            command “show ip interface” display?
            What are three advantages of using named
            access lists?
            If there are no matches to the parameters define
            in an ACL, what happens?
            What is the default “last command” in Access
            Control List on Cisco devices that is not visible?

            Select the commands that will apply the ACL in
            the diagram to filter traffic going to the
            192.168.2.0 network:




                - If you own both routers:
                - If you own Router 1:
                - If you own Router 2:
            Extended ACLs are placed/deployed where?

            Create a Named Extended Access List to
            prevent host 210.93.105.50 from accessing an
            FTP server located at 192.5.5.148




            Name and describe the three types of Complex
            Access Control List:




?.?.?.?     What is the command syntax to set the time and
            date on a Cisco router?
            What command would be used to show the
            current time and date settings?
