Which type of Cisco firewall uses Zone-Based Policy Firewall (ZBPFW)?

1. Cisco ASA 5500 Series

2. Cisco IOS firewalls

3. Cisco PIX 500 Series

4. Cisco Firewall Services Module

The correct answer is: Cisco IOS firewalls

The correct type of Cisco firewall that uses Zone-Based Policy Firewall (ZBPFW) is Cisco IOS firewalls. Zone-Based Policy Firewall provides a more flexible approach to defining policies and managing security within the device. It works by classifying interfaces into zones and then defining policies that govern the traffic between these zones, allowing for more granular control over how traffic is handled depending on its source and destination zones. Unlike the other options, which may use different methods for firewall policy configurations, Cisco IOS firewalls are specifically designed to integrate advanced features like ZBPFW. This integration allows network administrators to implement complex policies more intuitively by simply defining interactions between zones rather than configuring each interface individually. This makes it easier to manage security in dynamic environments, improving the overall effectiveness of the firewall's operation.
