Comprehensive and Detailed In-Depth Step-by-Step Explanation:The customer’s AWS environment currently uses the native AWS cloud service provider (CSP) firewall (e.g., AWS Network Firewall or Security Groups), which offers limited application visibility and advanced threat prevention compared to next-generation firewalls (NGFWs). The customer requires a solution that enhances security with application-layer visibility, advanced threat prevention, and integration with the native AWS management interface. The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation provides guidance on selecting the appropriate solution for AWS cloud security.

Cloud NGFW for AWS (Option B): Cloud NGFW for AWS is a cloud-native firewall service designed specifically for AWS environments, providing advanced application visibility (via App-ID), threat prevention (via WildFire, Threat Prevention, and URL Filtering), and scalable security for cloud applications. It integrates natively with the AWS Management Console, allowing customers to manage the firewall using familiar AWS tools (e.g., VPC, Route 53, CloudWatch) without requiring additional management platforms like Panorama. The documentation emphasizes Cloud NGFW’s ability to leverage AWS-native services for deployment, scalability, and management, meeting the customer’s need for enhanced visibility, advanced threat protection, and native AWS integration. This solution addresses the limitations of the native AWS firewall by offering Layer 7 inspection and comprehensive security features while maintaining simplicity through AWS’s management interface.

Options A (Palo Alto Networks CDSS bundle for AWS firewalls), C (AWS VPC VM-Series firewalls), and D (AWS Software credits) are incorrect. The Palo Alto Networks CDSS bundle (Option A) refers to Cloud-Delivered Security Services (e.g., Threat Prevention, WildFire), but it is not a standalone firewall solution; it enhances existing firewalls (e.g., Cloud NGFW or VM-Series) and does not integrate natively with the AWS Management Console as a primary firewall. “AWS VPC VM-Series firewalls” (Option C) is not a standard term; VM-Series firewalls are deployed in AWS VPCs, but they require separate management (e.g., via Panorama) and do not natively integrate with the AWS Management Console for full management, introducing complexity the customer wants to avoid. AWS Software credits (Option D) are a licensing model, not a firewall solution, and do not address the customer’s need for visibility, protection, or native management, making it irrelevant for this use case.
