You need to identify which DNS record must be implemented for the planned federation relationship.
Which DNS record should you identify?
To answer, select the appropriate configurations for the DNS record in the answer area.

Explanation/Reference:
Note:
Protocol/TCP or UDP/Port,Source (IP address), Destination (IP address), Comments *XMPP/TCP/5269
IP address or addresses of XMPP federated partners
Access Edge External Standard server-to-server communication port for XMPP. Allows communication to the Edge-deployed XMPP proxy from federated XMPP partners
*XMPP/TCP/5269
Access Edge External IP address or addresses of XMPP federated partners Standard server-to-server communication port for XMPP. Allows communication from the Edge-deployed XMPP proxy to federated XMPP partners
Extensible Messaging and Presence Protocol (XMPP) TCP PORT 5269
Planned Federation Relationship in Litware-Case A is XMPP Federation The Partner Company uses XMPP for IM
Answer is: Use Port TCP/5269 which is for XMPP Federation
Port Summary - Single Consolidated Edge with Public IP Addresses The Lync Server 2013, Edge Server functionality described in this scenario architecture is very similar to what was implemented in Lync Server 2010. The most noticeable addition is the port 5269 over TCP entry for the extensible messaging and presence protocol (XMPP). Lync Server 2013 optionally deploys an XMPP proxy on the Edge Server or Edge pool and the XMPP gateway server on the Front End Server or Front End pool. Planning information for the reverse proxy and federation are found in Scenarios for Reverse Proxy and Planning for SIP, XMPP Federation and Public Instant Messaging sections, respectively.
Port and Protocol Details
We recommend that you open only the ports required to support the functionality for which you are providing external access.
For remote access to work for any edge service, it is mandatory that SIP traffic is allowed to flow bidirectionally as shown in the Inbound/Outbound edge traffic figure. Stated another way, the SIP messaging to and from the Access Edge service is involved in instant messaging (IM), presence, web conferencing, audio/video (A/V) and federation.
Firewall Summary for Single Consolidated Edge with Public IP Addresses: External Interface
In addition to IPv4, the Edge Server now supports IPv6. For clarity, only IPv4 is used in the scenarios.
