A network engineer is planning on deploying a Cisco Secure Firewall Threat Defense Virtual appliance in transparent mode. Which two virtual environments support this configuration? (Choose two.)

OSI (Open Systems Interconnection) is a conceptual model for network communication, not a virtual environment or hypervisor.

AWS (Amazon Web Services) supports FTDv, but transparent mode is generally not recommended or natively supported in public cloud environments like AWS VPCs due to their inherent routed network architectures. Routed mode is the standard deployment for FTDv in AWS.

GCP (Google Cloud Platform) supports FTDv, but similar to AWS, transparent mode is typically not the recommended or practically feasible deployment due to the cloud's native networking constructs. Routed mode is the standard deployment for FTDv in GCP.

KVM (Kernel-based Virtual Machine) is a supported hypervisor for Cisco FTDv, and transparent mode deployment is fully functional within KVM environments.

ESXi (VMware vSphere Hypervisor) is a widely supported hypervisor for Cisco FTDv, where transparent mode deployments are common and well-documented.
