PSE-SWFW-Pro-24 Exam Dumps : Palo Alto Networks Systems Engineer Professional - Software Firewall

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 to both in 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 firewalls can be integrated into Azure Virtual WAN hubs as secured virtual hubs, Cloud NGFW for Azure is not directly 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 is not the management plane for Palo Alto Networks VM-Series or Cloud NGFW for AWS. These are managed by Panorama.  

Palo Alto Networks References:

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.

AWS: Cloud NGFW for AWS leverages AWS Gateway Load Balancer (GWLB) endpoints. These endpoints require dedicated subnets in your VPC for each Availability Zone where you want to deploy the Cloud NGFW. This ensures high availability and proper traffic routing.  

Let's look at why the other options are not the primary answer:

Google Cloud Platform (GCP): While GCP has its own networking constructs, Cloud NGFW for GCP doesn't have the same dedicated subnet requirement for endpoints as AWS.

Alibaba Cloud: I don't have specific information about Cloud NGFW deployment models for Alibaba Cloud.

Microsoft Azure: Cloud NGFW for Azure integrates with Azure Virtual WAN and doesn't have the same dedicated subnet requirement for endpoints as AWS.

The CN-Series firewalls are containerized firewalls designed to protect Kubernetes environments. They offer several deployment methods to integrate with Kubernetes orchestration.

A. Terraform templates: Terraform is an Infrastructure-as-Code (IaC) tool that allows you to define and provision infrastructure using declarative configuration files. 1 Palo Alto Networks provides Terraform modules and examples to deploy CN-Series firewalls, enabling automated and repeatable deployments.

B. Panorama plugin for Kubernetes: While Panorama is used to manage CN-Series firewalls centrally, there isn't a direct "Panorama plugin for Kubernetes" for deploying the firewalls themselves. Panorama is used for management after they're deployed using other methods.

C. YAML file: Kubernetes uses YAML files (manifests) to define the desired state of deployments, including pods, services, and other resources. You can deploy CN-Series firewalls by creating YAML files that define the necessary Kubernetes objects, such as Deployments, Services, and ConfigMaps. This is a core method for Kubernetes deployments.

D. Helm charts: Helm is a package manager for Kubernetes. Helm charts package Kubernetes resources, including YAML files, into reusable and shareable units. Palo Alto Networks provides Helm charts for deploying CN-Series firewalls, simplifying the deployment process and managing updates.

E. Docker Swarm: Docker Swarm is a container orchestration tool, but CN-Series firewalls are specifically designed for Kubernetes and are not deployed using Docker Swarm.

The Palo Alto Networks documentation clearly outlines these deployment methods:

CN-Series Deployment Guide: This is the primary resource for deploying CN-Series firewalls. It provides detailed instructions and examples for using Terraform, YAML files, and Helm charts. You can find this on the Palo Alto Networks support portal by searching for "CN-Series Deployment Guide".
