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

Credit-based flexible licensing provides flexibility in deploying and managing Palo Alto Networks software firewalls. Let's analyze the options:

A. Create virtual Panoramas: While Panorama can manage software firewalls, credit-based licensing is primarily focused on the firewalls themselves (VM-Series, CN-Series, Cloud NGFW), not on Panorama. Panorama has its own licensing model.

B. Add Cloud-Delivered Security Services (CDSS) subscriptions to CN-Series firewalls: This is a VALID benefit. Credit-based licensing allows customers to use credits to enable CDSS subscriptions (like Threat Prevention, URL Filtering, WildFire) on CN-Series firewalls. This provides flexibility in choosing and applying security services as needed.

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 provides various reference architectures for deploying VM-Series firewalls in different cloud environments. Let's examine the options:

A. Cloud NGFW for AWS: Combined Model: While Cloud NGFW is an offering, the term "Combined Model" isn't a standard, documented reference architecture name. Cloud NGFW for AWS focuses on simplified deployment and management but doesn't use this specific terminology for its deployment models.

B. AWS VM-Series: Isolated Transit Gateway: This is a VALID deployment model. It involves deploying VM-Series firewalls in an isolated VPC connected to AWS Transit Gateway. This provides centralized security inspection for traffic flowing between different VPCs and on-premises networks connected to the Transit Gateway.
