B) Install the Lync Audio/Video ActiveX Plugin.
C) Extract the MSI from the executable and run the install.

2. Your customer's company has a main office and five branch offices located in different cities. Your customer has a Microsoft Lync Server 2013 datacenter configured with Enterprise Voice at the main office. The customer has deployed a Survivable Branch Appliance (SBA) at the first branch office and connected it to a public switched telephone network (PSTN) by using a Tl trunk line provided by your service provider. The gateway is configured to use fully qualified domain names (FQDNs). All functionality has been tested by using pilot users at the branch office. The customer reports that they tested branch isolation by disconnecting the wide area network (WAN) from their branch office and making an outbound call. The call was successful. Next, they made an inbound call to the branch office and the call failed. To troubleshoot the issue, you begin a trace of IncomingAndOutgoingCalls by using centralized logging, and make an inbound call. You open the log in snooper and search for incoming calls with the phone number from which you are calling. You do not find any messages. You open the syslog from the gateway side of the SBA and discover that messages are sent to the Lync Mediation server pool, but no responses have been received. You connect the WAN from the branch office and make an inbound call. The call is successful. Your investigation suggests that there is a configuration error on the Gateway side of the SBA. You need to identify the configuration error that causes inbound calls to fail. What should you check?

A) Route settings of the gateway
B) The domain controller at the branch office
C) Dynamic Host Configuration Protocol (DHCP) options on the branch DHCP server
D) DNS settings on the gateway

-three Front End pools with three Front End 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.

5.Answer the incoming call by using DeskPhone2.
6.From DeskPhone1, transfer the call that you have on hold.
