Selected Answer: BD

• An Expressway-E located outside the firewall on the public network or in the DMZ, which acts as the firewall traversal server. Unified Communications features such as Mobile and Remote Access or Jabber Guest, require a Unified Communications traversal zone connection between the Expressway-C and the Expressway-E. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/admin_guide/X14-0/exwy_b_cisco-expressway-administrator-guide/exwy_m_unified-communications.html
