Exam PCNSA topic 1 question 4 discussion

Answer is correct

In a Palo Alto Networks firewall, an interface can be assigned to only one zone. This is a fundamental design of the firewall's architecture to ensure clear and logical traffic segmentation. Zones are used to group interfaces for applying security policies, and each interface must belong to exactly one zone to ensure proper policy enforcement. Traffic between zones is inspected and controlled based on security rules, while traffic within the same zone does not require a policy unless intra-zone security rules are defined.

In a Palo Alto Networks firewall, an interface can only be assigned to one zone at a time. Zones are logical groupings that define trust levels and policy boundaries, and an interface must belong to a single zone to ensure proper security policy enforcement. Assigning an interface to multiple zones is not supported because it would create ambiguity in traffic handling.

Security zones are a logical way to group physical and virtual interfaces on the firewall to control and log the traffic that traverses specific interfaces on the network. An interface on the firewall must be assigned to a security zone before the interface can process traffic. A zone can have multiple interfaces of the same type assigned to it (for example, tap, Layer 2, or Layer 3 interfaces), but an interface can belong to only one zone.

D is correct

A zone can have multiple interfaces of the same type assigned to it (such as tap, layer 2, or layer 3 interfaces), but an interface can belong to only one zone. So the answer is D
