How do zones enhance security in a Palo Alto NGFW deployment?

The correct answer is A. By segmenting traffic and enabling granular policy enforcement. Zones are the foundational building block of Palo Alto NGFW security architecture. All interfaces are assigned to zones, and security policies are written based on source and destination zone pairs. This zone-based model segments the network into logical trust boundaries (e.g…

Explanation

Zones are the foundational building block of Palo Alto NGFW security architecture. All interfaces are assigned to zones, and security policies are written based on source and destination zone pairs. This zone-based model segments the network into logical trust boundaries (e.g., Trust, Untrust, DMZ) and enforces granular policy - specifying which applications, users, and content are allowed between any two zones. Traffic within the same zone is permitted by default; traffic crossing zone boundaries is subject to policy inspection. Options B, C, and D describe things zones do not directly control: SSL decryption is governed by decryption policies, logging is configured per policy rule, and routing paths are determined by routing protocols or static routes.
