DRAG DROP You deploy a Microsoft Lync Server 2013 Enterprise pool named Lync2013.contoso.local.
The pool is configured with
the Session Initiation Protocol (SIP) domain litware.com. The environment includes the following:
-a Front End Server named Lync2013FE1
-a Back End Server named Lync2013BE
-an Edge Server named Lync2013Edge that is a member of Edge pool Edgepool.contoso.local
Your Lync 2013 topology supports the following access, meeting, administration, and external web service URLs:
-https://Dialin.litware.com
-https://Meet.litware.com
-https://Admin.contoso.local
-https://external.litware.com
You want to support external Lync Web App clients.
You plan to publish Lync 2013 HTTP Web services through a reverse proxy. You need to issue a certificate to publish Lync 2013 Web services through a reverse proxy firewall. Which three steps should you perform in sequence? (To answer, move the appropriate three actions from the list of actions to the answer area and arrange them in the correct order.)

정답:

Explanation:
Box 1:

Box 2: Create a publishing rule on the reverse proxy firewall to forward requests to the Front End Server.
Box 3: Install the certificate on reverse proxy firewall.
Note:
*Incorrect: No mobile devices or autodiscovery needed in this scenario.
*(step 1) You need to install the root certification authority (CA) certificate on the server running Microsoft Forefront Threat Management Gateway 2010 for the CA
infrastructure that issued the server certificates to the internal servers running Microsoft Lync Server 2013. You also must install a public web server certificate on your reverse proxy server. This certificate's subject alternative names should contain the published external fully qualified domain names (FQDNs) of each pool that is home to users enabled for remote access, and the external FQDNs of all Directors or Director pools that will be used within that Edge infrastructure. The subject alternative name must also contain the meeting simple URL, the dial-in simple URL, and, if you are deploying mobile applications and plan to use automatic discovery, the external Autodiscover Service URL as shown in the following table. *(step 2) If your internal deployment consists of more than one Standard Edition server or Front End pool, you must configure
web publishing rules for each external web farm FQDN and you will either need a certificate and web listener for each, or you must obtain a certificate whose subject alternative name contains the names used by all of the pools, assign it to a web listener, and share it among multiple web publishing rules. *(step 3 ) You create a certificate request on the reverse proxy. You create a request on another computer, but you must export the signed certificate with the private key and import it onto the reverse proxy once you have received it from the public certification authority.

You support a customer whose Microsoft Lync Server 2013 environment includes a single Lync Server 2013 Standard Edition pool located in a main office and four branch offices that are connected by a 3MB dedicated wide area network (WAN) link, with 100 users in each office. The Lync client's IP address is 10.0.0.100. The Lync IP server's address is 192.168.255.2. Quality of Service (QoS) is configured in Lync server for voice to use the differentiated services code point (DSCP) with a value of 46.
Users in the branch offices report poor audio quality during conferences that are hosted on Lync. The results of a network trace include the following information: Based on the network trace, you need to identify the most likely cause of the call quality issues. Which setting should you modify?

• A.STUN port
• B.Geo IP
• C.DSCP value
• D.MTU
