Palo Alto Networks SystemsEngineer Professional - Software Firewall PSE-SWFW-Pro-24 Exam Questions with Experts Answers Updated Recently

This question asks about common characteristics of Cloud NGFW (specifically referring to Cloud NGFW for AWS and Azure) and VM-Series firewalls.

B. In Azure and AWS, both offerings can be managed by Panorama.This is correct. Panorama is the centralized management platform for Palo Alto Networks firewalls, including both VM-Series and Cloud NGFW deployments in AWS and Azure. Panorama allows for consistent policy management, logging, and reporting across these different deployment models.  

D. In Azure, inbound destination NAT configuration also requires source NAT to maintain flow symmetry.This is accurate specifically within the Azure environment. Due to how Azure networking functions, when performing destination NAT (DNAT) for inbound traffic to resources behind a firewall (whether VM-Series or Cloud NGFW), it's typically necessary to also implement source NAT (SNAT) to ensure return traffic follows the same path. This maintains flow symmetry and prevents routing issues. This is an Azure networking characteristic, not specific to the Palo Alto offerings themselves, but it applies tobothin Azure.  

E. In Azure and AWS, internal (east-west) flows can be inspected without any NAT.This is generally true. For traffic within the same Virtual Network (Azure) or VPC (AWS), both VM-Series and Cloud NGFW can inspect traffic without requiring NAT. This is a key advantage for microsegmentation and internal security. The firewalls can act as transparent security gateways for internal traffic.

Why other options are incorrect:

A. In Azure, both offerings can be integrated directly into Virtual WAN hubs.While VM-Series firewallscanbe integrated into Azure Virtual WAN hubs as secured virtual hubs, Cloud NGFW for Azure isnotdirectly integrated into Virtual WAN hubs in the same way. Cloud NGFW for Azure uses a different architecture, deploying as a service within a virtual network.  

C. In AWS, both offerings can be managed by AWS Firewall Manager.AWS Firewall Manager is a service for managing AWS WAF, AWS Shield, and network firewalls (AWS Network Firewall). While AWS Firewall Manager can be used to manage AWS Network Firewall, it isnotthe management plane for Palo Alto Networks VM-Series or Cloud NGFW for AWS. These are managed by Panorama.

To validate these points, refer to the following documentation areas on the Palo Alto Networks support site (live.paloaltonetworks.com):

Panorama Administrator's Guide:This guide details the management capabilities of Panorama, including managing VM-Series and Cloud NGFW deployments in AWS and Azure.  

Cloud NGFW for AWS/Azure Documentation:This documentation outlines the architecture and deployment models of Cloud NGFW, including its management and integration with cloud platforms.

VM-Series Deployment Guides for AWS/Azure:These guides describe the deployment and configuration of VM-Series firewalls in AWS and Azure, including networking considerations and integration with cloud services.

Dynamic Address Groups (DAGs) use tags to dynamically populate their membership.  

Why A, B, and C are correct:

A. Static tags are part of the configuration on the firewall, while dynamic tags are part of the runtime configuration:Static tags are configured directly on objects. Dynamic tags are applied based on runtime conditions (e.g., by the VMMonitoring agent or User-ID agent).  

B. Dynamic Address Groups that are referenced in Security policies must be committed on the firewall:Like any configuration change that affects security policy, changes to DAGs (including tag associations) must be committed to take effect.

C. To dynamically register tags, use either the XML API or the VM Monitoring agent on the firewall or on the User-ID agent:These are the mechanisms for dynamically applying tags based on events or conditions.

Why D and E are incorrect:

D. IP-Tag registrations to Dynamic Address Groups must be committed on the firewall after each change:While changes to theconfigurationof a DAG (like adding a new tag filter) require a commit, theregistrationof IP addresses with tags does not. The DAG membership updates dynamically as tags are applied and removed.

E. Dynamic Address Groups use tags as filtering criteria to determine their members, and filters do not use logical operators:DAG filtersdosupport logical operators (AND, OR) to create more complex membership criteria.

Palo Alto Networks References:

PAN-OS Administrator's Guide:The section on Dynamic Address Groups provides details on how they work, including the use of tags as filters and the mechanisms for dynamic tag registration.  

VM Monitoring and User-ID Agent Documentation:These documents explain how these components can be used to dynamically apply tags.

The documentation confirms the correct statements regarding static vs. dynamic tags, the need to commit DAG changes, and the methods for dynamic tag registration. It also clarifies that DAG filtersdouse logical operators and that IP-tag registrations themselves don't require commits.

These resources provide deep technical expertise and strategic guidance.

A. Palo Alto Networks consulting engineers:Consulting engineers are highly skilled technical resources who can provide specialized assistance with complex deployments, integrations, and architectural design.

B. Professional services delivery:While professional services can provide valuable assistance, they are more focused on implementation and deployment tasks rather than pre-sales technical assistance, innovation consultation, and industry differentiation insights.

C. Technical account managers (TAMs):TAMs are primarily focused on post-sales support, ongoing customer success, and relationship management. While they have technical knowledge, their role is not primarily pre-sales technical assistance.

D. Reference architectures:These are documented best practices and design guides for various deployment scenarios. They are invaluable for understanding how to design and implement secure network architectures using Palo Alto Networks products.

E. Palo Alto Networks principal solutions architects:These are senior technical experts who possess deep product knowledge, industry expertise, and strategic vision. They can provide high-level architectural guidance, thought leadership, and innovation consultation.
