Which actions required for a firewall configuration on a Mobile and Remote Access

through Cisco Expressway deployment?

Options:

A.

The traversal zone on Expressway-c points to Expressway-e through the peer address field on the traversal zone, which specifies the Expressway-e server address. For dual NIC deployments, set the Expressway-e address using an FQDN that resolves the IP address of the internal interface
