You support a customer whose network environment includes Microsoft Lync Server 2013. A firewall filters all inbound traffic from the Internet. All outbound IP traffic is permitted. Users report voice quality problems when they attempt to communicate with external participants. You need to ensure that Lync users are able to communicate with external participants. Which two ports should you open on the firewall? (Each correct answer presents part of the solution. Choose two.)
You support a Microsoft Lync Server 2013 environment that includes:
-Two Enterprise consolidated Lync servers in a single pool,
-Two Edge consolidated Lync servers in a single pool,
-One Microsoft Office Web Apps server, and
-One reverse HTTP(S) proxy server. Microsoft Exchange 2010/Microsoft Outlook 2013 are used for internal email and Unified Messaging. The email solution has been used within the company for an extended time without any issues. Unified Messaging has been configured and set
up as part of the Lync 2013 implementation project. You plan to deploy Enterprise Voice for all users, including users who have Lync Phone Edition (LPE) devices that are connected by using a LAN cable and a USB cable. You begin migrating test accounts. When a test user signs into Outlook 2013 and Lync 2013, all communications appear to be working as expected. Outlook creates the user profile as expected and logs into the test user mailbox. The test user signs into Lync as expected and is able to communicate with Exchange by using Exchange Web Services (EWS).
After the test user signs into Lync, a prompt is displayed requesting user credentials for the Lync Phone Edition device. The test user enters his credentials and the phone signs into Lync; however, after a short period of time, a yellow warning triangle appears on every test LPE device. In reviewing the LPE device for errors, you discover that Exchange integration is failing with the following error: "Connection to Microsoft Exchange is unavailable. Please contact your support team." Logs from the LPE Device are displayed in the Exhibit 1. (Click the Exhibit button.)
Internet Information Services (IIS) logs on the Exchange Client Access server (CAS) are displayed in Exhibit 2. (Click the Exhibit button.)
You need to ensure that the LPE device can authenticate to EWS. What should you do?
DRAG DROP You support a Microsoft Lync Server 2013 environment for a customer named Litware, Inc. The worldwide network includes the following:
-15,000 Enterprise Voice enabled users
-three Front End pools with three Front End Servers in each pool
-three Edge Server pools with two Edge Servers in each pool
-two Group Chat pools with two Group Chat Servers in each pool
-20 Survivable Branch Appliances (SBAs) deployed at various offices
Of the 15,000 users, 6,000 have Polycom CX600 phones on their desks. Each pool
has redundant session initiation protocol (SIP) trunk settings with a local SIP trunk
provider at its respective pool. An executive assistant receives a call from a
customer. He puts the call on hold and calls the executive. After he talks to the
executive, he transfers the call to the executive. The executive assistant reports that
the call fails to transfer, and that he gets the call back. This results in him taking a
message. Based on this user report, you perform the following actions:
1.Start the ClsController.exe with only one Front End pool selection.
2.Make a call from your mobile phone to a CX600 desk phone named DeskPhone1.
3.Answer the incoming call by using DeskPhone1 and put the call on hold.
4.From DeskPhone1, dial the number of a second CX600 phone named DeskPhone2.
5.Answer the incoming call by using DeskPhone2.
6.From DeskPhone1, transfer the call that you have on hold.
After you attempt to transfer the call from DeskPhone1 to DeskPhone 2, you
observe that the call failed to transfer and returned back to DeskPhone1.
You generate a Lync.log file.
You need to identify the problem by using the quick search capabilities of the
Snooper tool. Which action should you perform for each troubleshooting activity?
(To answer, drag the appropriate action to the correct troubleshooting activity or activities. Each action may be used
once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

You need to ensure that mobile users are able to receive instant messages at all times.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
