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

Comprehensive and Detailed In-Depth Step-by-Step Explanation:Cloud NGFW for AWS is a cloud-native firewall service designed to provide scalable and flexible security in Amazon Web Services (AWS) environments. The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation describes the deployment models supported by Cloud NGFW to meet various architectural needs in public clouds.

Distributed (Option B): In a distributed deployment model, Cloud NGFW instances are deployed across multiple Availability Zones (AZs) or Virtual Private Clouds (VPCs) in AWS. This model ensures scalability, high availability, and localized traffic inspection, reducing latency and improving performance. The documentation highlights distributed deployment as a key feature for large-scale AWS environments, leveraging AWS’s auto-scaling and load-balancing capabilities.

Centralized (Option D): In a centralized deployment model, a single Cloud NGFW instance or a cluster of instances serves as a central point for inspecting traffic across multiple VPCs or regions in AWS. This model simplifies management and policy enforcement but may introduce latency for distributed workloads. The documentation notes that centralized deployment is suitable for smaller environments or specific use cases requiring unified control, integrated with AWS Transit Gateway or VPC peering.

Options A (Hierarchical) and C (Linear) are incorrect. Hierarchical deployment is not a supported model for Cloud NGFW in AWS, as it implies a multi-tiered structure not aligned with the cloud-native architecture of Cloud NGFW. Linear deployment is not a recognized model in the documentation for Cloud NGFW, which focuses on distributed and centralized approaches to meet AWS scalability and security needs.

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.

The question asks about Cloud NGFW offerings under the CSP's own brand name. This means the CSP is offering the service as their own, even though it's powered by Palo Alto Networks technology.

A. Oracle Cloud Infrastructure (OCI): OCI offers Oracle Cloud Infrastructure Network Firewall, which is powered by Palo Alto Networks' Cloud NGFW technology. It is branded as an Oracle service.

B. IBM Cloud (previously Softlayer): While Palo Alto Networks products can be deployed in IBM Cloud, there isn't a branded Cloud NGFW offering by IBM itself.

C. Alibaba Cloud: Similar to IBM Cloud, while Palo Alto Networks products can be used, Alibaba Cloud does not offer a rebranded Cloud NGFW service.

D. Google Cloud Platform (GCP): GCP offers Network Firewall Plus, which is powered by Palo Alto Networks' Cloud NGFW technology. It is branded as a Google
