Palo Alto Networks PSE-SoftwareFirewall Exam Questions
- Topic 1: Software Firewall Fundamentals: This domain covers a variety of software firewall types, such as subscriptions to Cloud-Delivered Security Services, cloud next-generation firewalls, and VM-Series and CN-Series firewalls. It also looks at other licencing choices such pay-as-you-go, Enterprise Licence Agreement subscriptions, and Flex licencing.
- Topic 2: Securing Environments with Software Firewalls: This section focuses on methodologies for securing data centers, including segmentation, virtualization, application visibility and control, and VPN connectivity controls.
- Topic 3: Deployment Architecture: This domain looks at popular centralised and distributed VM-Series deployment types and describes how to use VM-Series firewalls in centralised and distributed environments, particularly for high availability scenarios and Google Cloud Platform deployments.
- Topic 4: Automation and Orchestration: This section covers software firewall management tools like Panorama, Helm charts, and cloud-specific interfaces. It also describes automation tools such as Ansible, Terraform, and AWS CloudFormation templates.

How are CN-Series firewalls licensed?
Data-plane vCPU Licensing:
The CN-Series firewalls are licensed based on the number of data-plane vCPUs. This licensing model reflects the processing power dedicated to handling traffic and security enforcement within the containerized environment.

Which two elements of the Palo Alto Networks platform architecture enable security orchestration in a software-defined network (SDN)? (Choose two.)
Full set of APIs enabling programmatic control of policy and configuration:
Palo Alto Networks provides a comprehensive set of APIs that allow for the automation and orchestration of security policies and configurations in an SDN environment.
PAN-OS API Guide
Dynamic Address Groups to adapt Security policies dynamically:
Dynamic Address Groups (DAGs) enable the firewall to automatically adjust policies based on dynamic conditions, crucial for SDN environments where network configurations frequently change.

What Palo Alto Networks software firewall protects Amazon Web Services (AWS) deployments with network security delivered as a managed cloud service?
The Cloud NGFW by Palo Alto Networks is a managed cloud service designed to provide advanced network security capabilities within AWS deployments. This service leverages Palo Alto Networks' technology to deliver scalable and comprehensive security without the need for users to manage the infrastructure themselves. It is ideal for organizations looking to integrate robust security within their cloud environments efficiently.

A customer in a VMware ESXi environment wants to add a VM-Series firewall and partition an existing group of virtual machines (VMs) in the same subnet into two groups. One group requires no additional security, but the second group requires substantially more security.
How can this partition be accomplished without editing the IP addresses or the default gateways of any of the guest VMs?
Creating a New Virtual Switch:
By creating a new virtual switch, you can segment the network within the ESXi environment. The VM-Series firewall can then be used to provide security controls between these virtual switches using virtual wire mode.

Moving Guests to New Virtual Switch:
Guests requiring additional security are moved to the new virtual switch, allowing the VM-Series firewall to inspect and control traffic between the switches. This setup does not necessitate changes to the existing IP addresses or default gateways of the VMs.

A CN-Series firewall can secure traffic between which elements?
The CN-Series firewalls are specifically designed to secure containerized environments. They can secure traffic between Kubernetes pods, which are the smallest deployable units in a Kubernetes cluster, and are often composed of one or more containers. The primary focus of CN-Series firewalls is to ensure security within Kubernetes environments by managing traffic and enforcing security policies at the pod level.
