Selected Answer: C
Recommended: Dual NIC Static NAT Deployment The following example illustrates the recommended deployment. It shows the typical DMZ configuration where the internal and external firewalls cannot route directly to each other, and dual-NIC devices such as Expressway-E are required to validate and forward the traffic between the isolated subnets. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/config_guide/X14-0/basic_config/exwy_b_cisco-expressway-e-and-expressway-c-basic-configuration-deployment-guide-x14-0.pdf
