What is a benefit of credit-based flexible licensing for software firewalls?

Comprehensive and Detailed In-Depth Step-by-Step Explanation :

Credit-based flexible licensing is a licensing model introduced by Palo Alto Networks to simplify the

deployment and management of software firewalls, including VM-Series, CN-Series, and Cloud NGFW.

The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation outlines the

benefits of this model, particularly its flexibility and scalability across different firewall types in cloud

85/103

and virtualized environments.

Creating Cloud NGFWs (Option D): Credit-based flexible licensing allows customers to use a pool of

NGFW credits to deploy and manage Cloud NGFWs in public cloud environments like AWS and Azure.

This licensing model provides the flexibility to allocate credits dynamically to create Cloud NGFW

instances as needed, without requiring separate licenses for each instance. It simplifies procurement,

reduces administrative overhead, and ensures scalability, making it a key benefit for customers adopting

cloud-native security solutions.

Options A, B, and C are incorrect. Permanently setting the capabilities of software firewalls (Option A)

contradicts the flexible nature of credit-based licensing, which is designed for dynamic allocation. Adding

Cloud-Delivered Security Services (CDSS) to CN-Series firewalls (Option B) is not a direct benefit of

flexible licensing; CDSS subscriptions are separate and can be applied independently of the licensing

model. Adding subscriptions to PA-Series firewalls (Option C) is irrelevant, as PA-Series firewalls are

physical appliances with fixed licensing, not covered under the credit-based flexible licensing model for

software firewalls.
