Which option is an ideal security application solution for a cloud data center use case?

The ASA 5505-X is a physical appliance and cannot be deployed inside a cloud data center environment, and Adaptive Security Manager does not scale for cloud-native management needs.

A physical Firepower NGFW appliance cannot be installed in a cloud data center, as cloud providers require virtual or cloud-native form factors rather than rack-mounted hardware.

The Cisco Firepower NGFW virtual appliance is purpose-built for cloud and virtualized environments where physical hardware cannot be deployed, and Cisco Firepower Management Center provides centralized management suitable for cloud data center scale and consistent policy enforcement.

Cisco Firepower Threat Defense physical appliances are hardware devices that reside on-premises or in colocation facilities, not inside hyperscale cloud provider infrastructure such as AWS.
