- Topic 1: Core Concepts: This section of the exam measures skills of network security engineers and covers foundational knowledge of how Palo Alto Networks products operate together within a security ecosystem. It includes the core components of PAN-OS, firewall and Panorama architecture, interface types, deployment strategies for decryption, use of User-ID, authentication policies, and virtual system design.
- Topic 2: Deploy and Configure Core Components: This section of the exam measures skills of systems engineers and covers the configuration of essential network security components. It includes management profiles, security profiles, zone protection, deployment architecture, and routing. Key focus areas include firewall high availability, NAT, VPN tunnels, certificate management, and application-based QoS.
- Topic 3: Deploy and Configure Features and Subscriptions: This section of the exam measures skills of network security engineers and covers the configuration and use of advanced firewall features and licensed subscriptions. Topics include App-ID rule creation, GlobalProtect VPN setup, decryption methods, User-ID mappings, WildFire threat intelligence, and web proxy configurations for both transparent and explicit deployments.
- Topic 4: Deploy and Configure Firewalls Using Panorama: This section of the exam measures skills of systems engineers and covers centralized firewall management using Panorama. It includes template stacks, device groups, configuration management, dynamic updates, role-based access, log collectors, and how Panorama interacts with managed devices in distributed environments.
- Topic 5: Manage and Operate: This section of the exam measures skills of network security engineers and covers the day-to-day operation and maintenance of Palo Alto Networks firewalls. It includes log forwarding setup, upgrade procedures, monitoring HA pairs, dynamic updates, and failover handling. Emphasis is placed on managing different commit types, identifying system issues, and customizing log behavior.
- Topic 6: Troubleshooting: This section of the exam measures skills of systems engineers and covers diagnostics and troubleshooting practices for a wide range of network security issues. It includes resolving VPN issues, interface misconfigurations, routing problems, decryption errors, resource protection, policy enforcement, and high availability events. It also focuses on using logs, packet captures, and system reports effectively.

What would allow a network security administrator to authenticate and identify a user with a new BYOD-type device that is not joined to the corporate domain?
For a network security administrator to authenticate and identify a user with a new BYOD-type device that is not joined to the corporate domain, the most effective method is to use an Authentication policy targeting users not yet identified by the system.
A . an Authentication policy with 'unknown' selected in the Source User field:
An Authentication policy allows the firewall to challenge unidentified users for credentials. By selecting 'unknown' in the Source User field, the policy targets users who have not yet been identified by the firewall, which would include users on new BYOD devices not joined to the domain.
Once the user provides valid credentials, the firewall can authenticate the user and map their identity to subsequent sessions, enabling the application of user-based policy rules and monitoring.
This approach ensures that new and unknown devices can be properly authenticated and identified without compromising security or requiring the device to be part of the corporate domain.
An internal audit team has requested additional information to be included inside traffic logs forwarded from Palo Alto Networks firewalls to an interal syslog server. Where can the firewall engineer define the data to be added into each forwarded log?
A firewall administrator configures the HIP profiles on the edge firewall where GlobalProtect is enabled, and adds the profiles to security rules. The administrator wants to redistribute the HIP reports to the data center firewalls to apply the same access restrictions using HIP profiles. However, the administrator can only see the HIP match logs on the edge firewall but not on the data center firewall
What are two reasons why the administrator is not seeing HIP match logs on the data center firewall? (Choose two.)
For HIP match logs to be visible on the data center firewall, the following conditions must be met:
HIP profiles added to security rules: HIP profiles must be applied to security rules on the data center firewall to enforce access restrictions based on the received HIP reports. If the HIP profiles are not associated with the security rules, the firewall will not evaluate traffic against these profiles, and consequently, no HIP match logs will be generated.
User-ID enabled on the incoming zone: User-ID must be enabled on the zone where the users are located in the data center firewall. The User-ID feature is responsible for mapping IP addresses to user names, which is critical for applying policies based on user identity and, by extension, for HIP-based policy enforcement.
The other options (A and D) are related to logging and log forwarding but would not directly impact the generation or visibility of HIP match logs on the data center firewall itself.
Which two actions can the administrative role called "vsysadmin" perform? (Choose two)
The vsysadmin role in Palo Alto Networks firewalls is a virtual system (vsys)-specific administrative role with limited privileges. It can commit changes to the candidate configuration of the assigned vsys (Option B) and create/edit Security policies and profiles specific to that vsys (Option C). This role is designed for multi-tenant environments where administrators manage only their assigned virtual systems.
Option A (configure resource limits) is a superuser or device-level task, not within vsysadmin's scope. Option D (configure interfaces) is also outside vsysadmin's permissions, as interface management is a device-wide function. Official documentation defines these privileges clearly.
A firewall administrator wants to be able at to see all NAT sessions that are going 'through a firewall with source NAT. Which CLI command can the administrator use?
