The question asks about a capability common to VM-Series deployments across Azure, GCP, and AWS, as described in the "Securing Applications" design guides.
C. Horizontal scalability through cloud-native load balancers: This is the correct answer. A core concept in cloud deployments, and emphasized in the "Securing Applications" guides, is using cloud-native load balancers (like Azure Load Balancer, Google Cloud Load Balancing, and AWS Elastic Load Balancing) to distribute traffic across multiple VM-Series firewall instances. This provides horizontal scalability, high availability, and fault tolerance. This is common across all three major cloud providers.
Why other options are incorrect:
A. BGP dynamic routing to peer with cloud and on-premises routers: While BGP is supported by VM-Series and can be used for dynamic routing in cloud environments, it is not explicitly highlighted as a common capability across all three clouds in the "Securing Applications" guides. The guides focus more on the application security aspects and horizontal scaling. Also, the specific BGP configurations and integrations can differ slightly between cloud providers.
B. GlobalProtect portal and gateway services: While GlobalProtect can be used with VM-Series in cloud environments, the "Securing Applications" guides primarily focus on securing application traffic within the cloud environment, not remote access. GlobalProtect is more relevant for remote user access or site-to-site VPNs, which are not the primary focus of these guides.
D. Site-to-site VPN: While VM-Series firewalls support site-to-site VPNs in all three clouds, this is not the core focus or common capability highlighted in the "Securing Applications" guides. These guides emphasize securing application traffic within the cloud using techniques like microsegmentation and horizontal scaling.
Palo Alto Networks References:
The key reference here is the "Securing Applications" design guides for VM-Series firewalls. These guides are available on the Palo Alto Networks support site (live.paloaltonetworks.com). Searching for "VM-Series Securing Applications" along with the name of the respective cloud provider (Azure, GCP, AWS) will usually provide the relevant guides
