Scalability:
FortiGate Cloud-Native Firewall (CNF) is designed to scale seamlessly with your cloud infrastructure, providing the necessary protection without requiring manual intervention for scaling (Option B).
Firewall-as-a-Service:
FortiGate CNF is offered as a Firewall-as-a-Service (FWaaS), which simplifies the deployment and management of firewall capabilities directly in the cloud environment (Option D).
Management:
FortiGate CNF can be managed using FortiManager and AWS Firewall Manager, providing comprehensive management capabilities both from Fortinet's platform and AWS's native management tools (Option E).
Other Considerations:
Option A (carrier-grade protection) is not specifically highlighted as a feature of FortiGate CNF.
Option C (uses AWS Elastic Load Balancing) is incorrect as FortiGate CNF operates independently of AWS ELB, although it can integrate with various AWS services.
