You have created a named access list called Blocksales. Which of the following is a valid command for applying this to packets trying to enter interface s0 of your router?

[A].	(config)# ip access-group 110 in
[B].	(config-if)# ip access-group 110 in
[C].	(config-if)# ip access-group Blocksales in
[D].	(config-if)# blocksales ip access-list in

Answer: Option C

Explanation:

Using a named access list just replaces the number used when applying the list to the router's interface. ip access-group Blocksales in is correct.
