• Question 512:

  You must install an Expressway Edge server pair to enable mobile and remote access for a customer network. Which two requirements are used to install an MRA solution successfully? (Choose two.)

  A. Configure your firewalls to allow traffic from Expressway-Core to Expressway-Edge servers and to allow traffic from internet hosts to Expressway-Edge servers. You do not need to configure firewall rules for traffic from Expressway-Edge to Expressway Core servers.
  B. You can deploy Edge servers with multiple network interfaces or with a single network interface. In both scenarios, you must enable NAT for the Internet-facing interface if you are using private Ip addresses.
  C. Make sure that Expressway-Edge and Expressway-Core servers have their server certificates signed by the same certification authority and the CA certificate is uploaded to the trusted CA store otherwise the Traversal zone will not work.
  D. Configure DNS SRV records according. Make sure that you can resolve DNS SRV record_collab-edge_tls.yourdomain.com outside your company network. Make sure that you cannot resolve it inside your company network.
  C. Make sure that Expressway-Edge and Expressway-Core servers have their server certificates signed by the same certification authority and the CA certificate is uploaded to the trusted CA store otherwise the Traversal zone will not work.
  D. Configure DNS SRV records according. Make sure that you can resolve DNS SRV record_collab-edge_tls.yourdomain.com outside your company network. Make sure that you cannot resolve it inside your company network.

• Question 516:

  Company X currently uses a Cisco Unified Communications Manager, which has been configured for IP desk phones and Jabber soft phones. Users report however that whenever they are out of the office, a VPN must be set up before their Jabber client can be used.

  B. An additional interface must be enabled on the Cisco UCM and placed in the same subnet at the Expressway.
  C. The customer firewall must be configured with any rule for the IP address of the external Jabber client.
  D. The Expressway server needs a neighbor zone created that points to Cisco UCM.
  E. Jabber cannot connect to Cisco UCM unless it is on the same network or a VPN is set up from outside.
  A. A SIP trunk has to be set up between the Expressway-C and Cisco UCM.
  D. The Expressway server needs a neighbor zone created that points to Cisco UCM.

• Question 517:
