How do Cloud NGFW instances get created when using AWS centralized deployments?

In a centralized Cloud NGFW for AWS deployment, the administrator first designates a security Virtual Private Cloud (VPC). The Cloud NGFW resource is then created by deploying NGFW endpoints into specific subnets within this selected security VPC. This VPC is connected to an AWS Transit Gateway, which centralizes traffic routing from multiple spoke VPCs to the security VPC for inspection by the Cloud NGFW. The core creation step is the deployment of the NGFW resource into the chosen VPC.

A: This option is incorrect because vWAN and virtual hubs are components of Microsoft Azure's networking architecture, not AWS. AWS uses Transit Gateways for similar centralized routing functions.

B: This is incorrect. The Cloud NGFW is a security inspection service; it does not replace the fundamental function of an AWS Internet Gateway (IGW), which enables internet connectivity for a VPC.

D: This option inaccurately describes the architecture. A security VPC is created to host the NGFW resource and uses a Transit Gateway for routing; the VPC itself is not created as a Transit Gateway.

1. Palo Alto Networks Official Documentation. Deployment Models for Cloud NGFW for AWS. "In a centralized architecture

you deploy the Cloud NGFW resource in a dedicated security VPC... The security VPC is attached to a transit gateway

which routes traffic between the security VPC and multiple spoke VPCs." This confirms the NGFW is deployed into a selected VPC (the security VPC) as part of a larger architecture using a Transit Gateway.

2. Palo Alto Networks Official Documentation. Create a Cloud NGFW for AWS. "When you create a Cloud NGFW resource

you select the VPC where you want to create the NGFW... You must also select at least two subnets

each in a different Availability Zone

where the service can create NGFW endpoints." This document details the creation process

explicitly stating that the resource is added to a selected VPC.

3. AWS Documentation. What is a transit gateway? "A transit gateway is a network transit hub that you can use to interconnect your virtual private clouds (VPCs) and on-premises networks." This source clarifies that a Transit Gateway is a distinct service used for interconnection

not something a VPC is "created as."
