This question asks about common characteristics of Cloud NGFW (specifically referring to Cloud NGFW for AWS and Azure) and VM-Series firewalls.
B. In Azure and AWS, both offerings can be managed by Panorama. This is correct. Panorama is the centralized management platform for Palo Alto Networks firewalls, including both VM-Series and Cloud NGFW deployments in AWS and Azure. Panorama allows for consistent policy management, logging, and reporting across these different deployment models.
D. In Azure, inbound destination NAT configuration also requires source NAT to maintain flow symmetry. This is accurate specifically within the Azure environment. Due to how Azure networking functions, when performing destination NAT (DNAT) for inbound traffic to resources behind a firewall (whether VM-Series or Cloud NGFW), it's typically necessary to also implement source NAT (SNAT) to ensure return traffic follows the same path. This maintains flow symmetry and prevents routing issues. This is an Azure networking characteristic, not specific to the Palo Alto offerings themselves, but it applies to both in Azure.
E. In Azure and AWS, internal (east-west) flows can be inspected without any NAT. This is generally true. For traffic within the same Virtual Network (Azure) or VPC (AWS), both VM-Series and Cloud NGFW can inspect traffic without requiring NAT. This is a key advantage for microsegmentation and internal security. The firewalls can act as transparent security gateways for internal traffic.
Why other options are incorrect:
A. In Azure, both offerings can be integrated directly into Virtual WAN hubs. While VM-Series firewalls can be integrated into Azure Virtual WAN hubs as secured virtual hubs, Cloud NGFW for Azure is not directly integrated into Virtual WAN hubs in the same way. Cloud NGFW for Azure uses a different architecture, deploying as a service within a virtual network.
C. In AWS, both offerings can be managed by AWS Firewall Manager. AWS Firewall Manager is a service for managing AWS WAF, AWS Shield, and network firewalls (AWS Network Firewall). While AWS Firewall Manager can be used to manage AWS Network Firewall, it is not the management plane for Palo Alto Networks VM-Series or Cloud NGFW for AWS. These are managed by Panorama.
