DRAG DROP You support a customer whose network environment includes a Microsoft Lync Server 2013 Standard Edition deployed for instant messaging
(IM), presence, voice, video, audio conferencing, video conferencing, and Enterprise Voice workloads. Your customer also has an IP Private Branch Exchange (PBX), which the company plans to decommission within the next three months. Your customer has deployed a session initiation protocol (SIP) trunk solution from a service provider with the Lync Server 2013 environment. You are also using a media gateway connecting the Lync Server 2013 and IP PBX for voice between the IP PBX phones and the Lync 2013 phones. You have eliminated the Tl connection to the IP PBX and you are using Lync 2013 Enterprise Voice services for all public switched telephone network
(PSTN) calls for all users. IP PBX phone users connect to the company meeting by using Lync's dial-out capability. IP PBX phone users report the following issues:
-The name and number displayed for incoming calls are incorrect.
-When users make outgoing calls, call quality deteriorates over time to the point that they cannot hear the other participants.
-Outgoing calls to PSTN sometimes get re-order tones.
-Users who join the conference by using the Call Me feature report issues with incoming calls, affecting both display and voice quality. You are unable to reproduce the issues by using test phone lines on IP PBX and test Lync
client accounts on Lync Server 2013.
You decide to use a user's telephone to try to reproduce the problem. You need to capture troubleshooting details from the Lync Server 2013 environment of a test call that uses the executive IP PBX Which four commands should you run in sequence?

DRAG DROP You support Microsoft Lync Server 2013 servers for an international company. You enable the Enhanced 9-1-1 (E9-1-1) emergency notification feature for users in a New York office. The users report that Lync prompts them to enter a location. You need to configure Lync to populate location information automatically. 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.

Correct Answer:

Explanation:
Box 1: Set the Location Required policy to Disclaimer.
Box 2: Populate the location database.
Box 3: Publish the location database.
Note:
*To enable clients to automatically detect their location within a network, you first need to configure the location database. If you do not configure a location database, and Location Required in the location policy is set to Yes or Disclaimer, the user will be prompted to manually enter a location. To configure the location database, you will perform the following tasks:
*To automatically locate clients within a network, you first need to populate the location database with a network wiremap, which maps network elements to civic (that is, street) addresses. You can use subnets, wireless access points, switches, and ports to define the wiremap. You can add addresses to the location database individually, or in bulk by using a CSV file that contains the column formats described in the following table.
