PSE-SWFW-Pro-24 Exam Dumps - Paloalto Networks PSE-Software Firewall Professional Questions and Answers

Palo Alto Networks offers various tools and programs for demonstrating its cybersecurity portfolio, including firewalls (VM-Series, CN-Series, Cloud NGFW), malware protection (WildFire), SASE (Prisma Access), and automation products. The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation and marketing materials describe these tools, focusing on their suitability for educational or presales purposes like a conference workshop.

Ultimate Test Drive (Option D): The Ultimate Test Drive is a hands-on, guided lab environment provided by Palo Alto Networks, allowing attendees to explore a wide range of products, including VM-Series firewalls, Cloud NGFW, Prisma Access (SASE), WildFire (malware protection), and automation tools (e.g., Ansible, Terraform). In a 3-4 hour workshop, attendees can interact with these solutions through preconfigured labs, gaining exposure to their functionality, integration, and benefits. The documentation and marketing materials highlight Ultimate Test Drive as the ideal tool for demonstrating the broadest portfolio, making it perfect for a conference setting with diverse interests in cybersecurity products.

Options A (Capture the Flag), B (Ultimate Lab Environment), and C (Demo Environment) are incorrect. Capture the Flag (Option A) is a gamified, security-focused exercise, not a comprehensive tool for demonstrating the full Palo Alto Networks portfolio, and it may not cover firewalls or automation products adequately in a short workshop. Ultimate Lab Environment (Option B) is not a standard Palo Alto Networks tool; it may refer to internal or custom labs but is not widely available or structured for public workshops like Ultimate Test Drive. Demo Environment (Option C) provides static demonstrations, not hands-on interaction, limiting exposure compared to the interactive Ultimate Test Drive, especially for a varied audience interested in multiple products.

CN-Series firewalls are specifically designed for containerized environments.  

Why A, C, and E are correct:

A. Prevention of sensitive data exfiltration from Kubernetes environments: CN-Series provides visibility and control over container traffic, enabling the prevention of data leaving the Kubernetes cluster without authorization.  

C. Inbound, outbound, and east-west traffic between containers: CN-Series secures all types of container traffic: ingress (inbound), egress (outbound), and traffic between containers within the cluster (east-west).  

E. Enforcement of segmentation policies that prevent lateral movement of threats: CN-Series allows for granular segmentation of containerized applications, limiting the impact of breaches by preventing threats from spreading laterally within the cluster.

Why B and D are incorrect:

B. All Kubernetes workloads in the public and private cloud: While CN-Series can protect Kubernetes workloads in both public and private clouds, the statement "all Kubernetes workloads" is too broad. Its focus is on securing the network traffic around those workloads, not managing the Kubernetes infrastructure itself.

D. All workloads deployed on-premises or in the public cloud: CN-Series is specifically designed for containerized environments (primarily Kubernetes). It's not intended to protect all workloads deployed in any environment. That's the role of other Palo Alto Networks products like VM-Series, PA-Series, and Prisma Access.  

Palo Alto Networks References: The Palo Alto Networks documentation on CN-Series firewalls clearly outlines these use cases. Look for information on:

CN-Series Datasheets and Product Pages: These resources describe the key features and benefits of CN-Series, including its focus on container security.

CN-Series Deployment Guides: These guides provide detailed information on deploying and configuring CN-Series in Kubernetes environments.

These resources confirm that CN-Series is focused on securing container traffic within Kubernetes environments, including data exfiltration prevention, securing all traffic directions (inbound, outbound, east-west), and enforcing segmentation

Comprehensive and Detailed In-Depth Step-by-Step Explanation:Palo Alto Networks uses a credit-based flexible licensing model (NGFW credits) for software firewalls, managed through deployment profiles in the Customer Support Portal. The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation describes the characteristics of flex credit profiles within a credit pool.

Each VM-Series firewall deployment profile can be either fixed or flexible until defined and saved (Option A): In the Customer Support Portal, deployment profiles for VM-Series firewalls can start as undefined (neither fixed nor flexible) and are configured as either fixed (specific license allocation) or flexible (using NGFW credits) before saving. This flexibility allows customers to adjust profiles based on needs, a feature highlighted in the documentation for managing software firewalls efficiently.

Allocate credits for use with Cloud NGFW for AWS and Azure (Option D): NGFW credits from a credit pool can be allocated to deploy and manage Cloud NGFW instances in AWS and Azure, in addition to VM-Series and CN-Series. The documentation notes that flex credit profiles enable customers to dynamically allocate credits across different firewall types, including cloud-native firewalls, ensuring scalability and cost efficiency in public cloud environments.

Options B (All firewalls activated to a deployment profile will have the same subscriptions) and C (The number of licensed cores must match the number of provisioned CPU cores per instance) are incorrect. Firewalls in a deployment profile can have different subscriptions based on specific needs, not necessarily the same, making Option B inaccurate. For flexible licensing, the number of licensed cores (vCPUs) does not need to match provisioned CPU cores exactly; licensing tiers are based on performance levels (e.g., Tier 1, Tier 2), not a one-to-one match, so Option C is not a characteristic of flex credit profiles.

A. DNS sinkholing: DNS sinkholing redirects DNS requests for known malicious domains to a designated server, preventing users from accessing those sites. It doesn't inherently protect or hide an internal network in outbound flows. It's more of a preventative measure against accessing malicious external resources.

B. User-ID: User-ID maps network traffic to specific users, enabling policy enforcement based on user identity. It provides visibility and control but doesn't hide the internal network's addressing scheme in outbound connections.

C. App-ID: App-ID identifies applications traversing the network, allowing for application-based policy enforcement. Like User-ID, it doesn't mask the internal network's addressing.

D. NAT (Network Address Translation): NAT translates private IP addresses used within an internal network to a public IP address when traffic leaves the network. This effectively hides the internal IP addressing scheme from the external network. Outbound connections appear to originate from the public IP address of the NAT device (typically the firewall), thus protecting and hiding the internal network's structure.

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.

The VM-Series tiering simplifies the product portfolio.

Why B is correct: The four-tier model (VE, VE-Lite, VE-Standard, VE-High) simplifies the selection process for customers by grouping VM-Series models based on performance and resource allocation. This makes it easier to choose the appropriate VM-Series instance based on their needs without having to navigate a long list of individual models.

Why A, C, and D are incorrect:

A. To obscure the supported hypervisor manufacturer into generic terms: The tiering is not related to obscuring hypervisor information. The documentation clearly states supported hypervisors.

C. To define the maximum limits for key criteria based on allocated memory: While memory is a factor in performance, the tiers are based on a broader set of resource allocations (vCPUs, memory, throughput) and features, not just memory.

D. To define the priority level of support customers expect when opening a TAC case: Support priority is based on support contracts, not the VM-Series tier.

Palo Alto Networks References: VM-Series datasheets and the VM-Series deployment guides explain the tiering model and its purpose of simplifying the portfolio.

Cloud NGFW for AWS supports two primary deployment models:

A. Hierarchical: This is not a standard deployment model for Cloud NGFW for AWS. Hierarchical typically refers to a parent-child relationship in management, which isn't the core focus of the Cloud NGFW's deployment models.

B. Centralized: This is a VALID deployment model. In a centralized deployment, the Cloud NGFW is deployed in a central VPC (often a Transit Gateway VPC) and inspects traffic flowing between different VPCs and on-premises networks. This provides a single point of control for security policies.

The question asks about Cloud NGFW management tasks performed inherently by the service within AWS and Azure. This means we are looking for tasks that are automated and handled by the Cloud NGFW service itself, not by the customer.

Here's a breakdown of why A, B, and C are correct and why D and E are incorrect, referencing relevant Palo Alto Networks documentation where possible (though specific, publicly accessible documentation on the inner workings of the managed service is limited, the principles are consistent with their general cloud and firewall offerings):

A. Horizontally scaling out to meet increased traffic demand: This is a core feature of cloud-native services. Cloud NGFW is designed to automatically scale its resources (compute, memory, etc.) based on traffic volume. This eliminates the need for manual intervention by the customer to provision or de-provision resources. This aligns with the general principles of cloud elasticity and autoscaling, which are fundamental to cloud-native services like Cloud NGFW. While explicit public documentation detailing the exact scaling mechanism is limited, it's a standard practice for cloud-based services and is implied in the general description of Cloud NGFW as a managed service.

B. Installing new content (applications and threats): Palo Alto Networks maintains the threat intelligence and application databases for Cloud NGFW. This means that updates to these databases, which are crucial for identifying and blocking threats, are automatically pushed to the service by Palo Alto Networks. Customers do not need to manually download or install these updates. This is consistent with how Palo Alto Networks manages its other security services, such as Threat Prevention and WildFire, where content updates are delivered automatically.

C. Installing new PAN-OS software updates: Just like content updates, PAN-OS software updates are also managed by Palo Alto Networks for Cloud NGFW. This ensures that the service is always running the latest and most secure version of the operating system. This removes the operational burden of managing software updates from the customer. This is a key advantage of a managed service.

D. Blocking high-risk S2C threats in accordance with SOC2 compliance: While Cloud NGFW does block threats, including server-to-client (S2C) threats, the management of this blocking is not inherently performed by the service in the context of SOC2 compliance. SOC2 is an auditing framework, and compliance is the customer's responsibility. The service provides the tools to achieve security controls, but demonstrating and maintaining compliance is the customer's task. The service does not inherently manage the compliance process itself.

E. Decrypting high-risk SSL traffic: While Cloud NGFW can decrypt SSL traffic for inspection (SSL Forward Proxy), the question asks about tasks inherently performed by the service. Decryption is a configurable option. Customers choose whether or not to enable SSL decryption. It is not something the service automatically does without explicit configuration. Therefore, it's not an inherent management task performed by the service.

In summary, horizontal scaling, content updates, and PAN-OS updates are all handled automatically by the Cloud NGFW service, making A, B, and C the correct answers. D and E involve customer configuration or compliance considerations, not inherent management tasks performed by the service itself.

The scenario describes a need for programmatic and automated updating of a custom URL category on a Palo Alto Networks firewall. The XML API is specifically designed for this kind of task. It allows external systems and scripts to interact with the firewall's configuration and operational data.

Here's why the XML API is the appropriate solution and why the other options are not:

D. XML API: The XML API provides a well-defined interface for making changes to the firewall's configuration. This includes creating, modifying, and deleting URL categories and adding or removing URLs within those categories. A script can be written to retrieve the list of "bad sites" from the company's application and then use the XML API to push those URLs into the custom URL category on the firewall. This process can be automated on a schedule. This is the most efficient and recommended method for this type of integration.

Why other options are incorrect:

A. Dynamic User Groups: Dynamic User Groups are used to dynamically group users based on attributes like username, group membership, or device posture. They are not relevant for managing URL categories.

B. SNMP SET: SNMP (Simple Network Management Protocol) is primarily used for monitoring and retrieving operational data from network devices. While SNMP can be used to make some configuration changes, it is not well-suited for complex configuration updates like adding multiple URLs to a category. The XML API is the preferred method for configuration changes.

C. Dynamic Address Groups: Dynamic Address Groups are used to dynamically populate address groups based on criteria like tags, IP addresses, or FQDNs. They are intended for managing IP addresses and not URLs, so they are not applicable to this scenario.

Palo Alto Networks References:

The primary reference for this is the Palo Alto Networks XML API documentation. Searching the Palo Alto Networks support site (live.paloaltonetworks.com) for "XML API" will provide access to the latest documentation. This documentation details the various API calls available, including those for managing URL categories.

Specifically, you would look for API calls related to:

Creating or modifying custom URL categories.

Adding or removing URLs from a URL category.

The XML API documentation provides examples and detailed information on how to construct the XML requests and interpret the responses. This is crucial for developing a script to automate the URL updates.

Palo Alto Networks Cloud-Delivered Security Services (CDSS) offer several advantages over other security solutions:

A. Individually targeted products provide better security than platform solutions: This is generally the opposite of Palo Alto Networks' philosophy. CDSS is a platform approach, integrating multiple security functions into a unified service. This integrated approach is often more effective than managing disparate point solutions.

B. Multi-vendor best-of-breed products provide security coverage on a per-use-case basis: While "best-of-breed" has its merits, managing multiple vendors increases complexity and can lead to integration challenges. CDSS provides a comprehensive set of security services from a single vendor, simplifying management and integration.

C. It requires no additional performance overhead when enabling additional features: This is a key advantage of CDSS. Because the services are cloud-delivered and integrated into the platform, enabling additional security functions typically does not introduce significant performance overhead on the firewall itself.

D. It provides simplified management through fewer consoles for more effective security coverage: CDSS is managed through Panorama or Strata Cloud Manager, providing a single pane of glass for managing multiple security functions. This simplifies management compared to managing separate consoles for different security products.

E. It significantly reduces the total cost of ownership for the customer: By consolidating security functions into a single platform and reducing management overhead, CDSS can help reduce the total cost of ownership compared to deploying and managing separate point solutions.
