Explanation:
Box 1: Front End Server Box 2: Edge Server Box 3: Mediation server For PSTN. Box 4: Front End Server Box 5: Edge Server Box 6: Director Server
In Lync Server Enterprise Edition, the Front End Server is the core server role, and runs many basic Lync Server functions. The Front End Server, along with the Back End Servers, are the only server roles required to be in any Lync Server Enterprise Edition deployment. A Front End pool is a set of Front End Servers, configured identically, that work together to provide services for a common group of users.
Edge Server or Edge pool in your perimeter network, if you want your deployment to support federated partners, public IM connectivity, an extensible messaging and presence protocol (XMPP) gateway, remote user access, participation of anonymous users in meetings, or Exchange Unified Messaging (UM).
Mediation Server is a necessary component for implementing Enterprise Voice and dial-in conferencing. Mediation Server translates signaling, and, in some configurations, media between your internal Lync Server infrastructure and a public switched telephone network (PSTN) gateway, IP-PBX, or a Session Initiation Protocol (SIP) trunk. You can run Mediation Server collocated on the same server as Front End Server, or separated into a stand-alone Mediation Server pool.
Directors can authenticate Lync Server user requests, but they do not home user accounts or provide presence or conferencing services. Directors are most useful to enhance security in deployments that enable external user access. The Director can authenticate requests before sending them on to internal servers. In the case of a denial-of-service attack, the attack ends with the Director and does not reach the Front End servers.
We recommend that you deploy a Director or Director pool in each central site that supports external user access and in each central site in which you deploy one or more Front End pools.
To enable support for XMPP federation, the Edge Federation must be enabled. Reference: Lync Server 2013, Server Roles
http://msdn.microsoft.com/en-us/library/lync/hh364907.aspx
"This is because sites that use SIP trunking must deploy Mediation Server in a separate pool from the Front End Servers. In all other instances, we recommend you collocate Mediation Server with Front End Server."
You plan to deploy a Microsoft Lync Online subscription that will contain a single SIP domain named contoso.com.
You need to identify which DNS records must be created to meet the following requirements:
-Provide users with the ability to sign in automatically by using Microsoft Lync 2013.
-Provide users with the ability to sign in automatically by using the Lync mobile application.
Which DNS records should you identify? (To answer, select the appropriate record name and destination for each requirement in the answer area.)
