Select ALL information types that the firewall material identifies as possible inputs to a traffic decision.

### Why this is right - **Source Internet Protocol (IP) address** is a traffic attribute the firewall can use to identify where a packet came from. - **Destination port** helps identify the service being requested. - **Connection state** helps a stateful firewall understand whether traffic belongs to an established session. ### The concept Firewalls compare traffic attributes with configured rules. The material also lists destination address, protocol, interface, and security zone. These properties can help determine whether traffic matches a rule. A user's screen preference is unrelated to the network packet information listed in the lesson. ### The other options - **D. The user's preferred screen colour**: this is not a packet or connection property and is not listed as a firewall decision input. ### Terms - **IP**: Internet Protocol. The network protocol used to address and route packets. - **Port**: A number used with network protocols to identify a service or application endpoint. ### Remember Firewall rules use network and connection attributes, not unrelated device preferences.
