HOTSPOT Your customer supports a Microsoft Lync Server 2013 environment. Users are unable to add a federated user to an AV conference. The affected users can view the federated user's presence, and the internal users' External Access Policy is configured to allow communication with federated users. You attempt to initiate a Telnet session to TCP port 5062 from your Lync Server 2013 Front End Server to your Lync Server 2013 Edge Server's internal interface, but you receive an error message that includes "Could not open a connection to the host, on port 5062: Connect failed." You decide to work with the network team to ensure that the Lync Server 2013 environment has the appropriate connectivity to ensure media path negotiation and media flow between the front end server and the Edge server. You need to ensure that users are able to add federated users to an AV conference. Which network ports should you confirm are open on the Lync Server 2013 Front End Server and on the Lync Server 2013 Edge Server? To answer, select the appropriate server or servers for each port in the answer area.

Correct Answer:

Explanation:

*STUN/MSTURN/TCP/443 / Edge Server internal interface / Fallback path for A/V media transfer between internal and external users, Survivable Branch Appliance or Survivable Branch Server if UDP communication cannot be established, TCP is used for file transfer and desktop sharing
*STUN/MSTURN/UDP/3478 / Edge Server internal interface / Preferred path for A/V media transfer between internal and external users, Survivable Branch Appliance or Survivable Branch Server
*5061 Access/SIP(MTLS)/TCP/5061 For federated and public IM connectivity using SIP
*5062 SIP/MTLS/TCP/5062 Authentication of A/V users (A/V authentication service) from Front End Server or Front End pool IP address or any Survivable Branch Appliance or Survivable Branch Server using this Edge Server
