Which statement about access lists that are applied to an interface is true?
Click on the arrows to vote for the correct answerA. B. C. D.
Access lists are used to control traffic flow in a network. When applied to an interface, an access list specifies which traffic is allowed to pass through the interface and which traffic is denied.
The statement that is true about access lists applied to an interface is A. You can configure one access list, per direction, per Layer 3 protocol.
This means that you can apply an access list to an interface in either the inbound or outbound direction, and you can apply one access list for each Layer 3 protocol. For example, you could have one access list for IPv4 traffic and another access list for IPv6 traffic, both applied to the same interface.
Option B is incorrect because you cannot apply multiple access lists with the same protocol in different directions. Only one access list can be applied per direction per protocol.
Option C is also incorrect because you can apply multiple access lists to an interface, as long as they are applied in different directions or for different Layer 3 protocols.
Option D is incorrect because there is a limit to the number of access lists that can be applied to an interface. However, this limit varies depending on the device and the available resources.
In summary, the correct answer is A. You can configure one access list, per direction, per Layer 3 protocol, when applying access lists to an interface.
