QUESTION 14
Drag and Drop Question
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 DeskPhone2, 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.)
