Which rule number matches the specified traffic with a destination address of 199.167.55.50?

1. Rule number 1

2. Rule number 2

3. Rule number 3

4. Rule number 4

The correct answer is: Rule number 3

The correct choice indicates that rule number 3 is the one that matches the specified traffic with a destination address of 199.167.55.50. In firewalls, rules are organized in a specific order, and each rule typically contains criteria that determine which traffic it will allow or deny based on parameters such as source and destination addresses, applications, and services. For a traffic flow to match a specific rule, the rule must explicitly allow or address the destination IP address among other conditions. This implies that rule number 3 contains the necessary conditions to match traffic directed at the IP address of 199.167.55.50, thereby allowing or denying that traffic as determined by the rule's action. In a practical scenario, administrators often inspect the rule set to ensure that the correct rule is prioritized appropriately in order to manage traffic flow effectively. Thus, understanding the specifics of each rule and their criteria is key to maintaining network security and ensuring that only the desired traffic is processed.
