Microsoft Lync 2013 Depth Support Engineer Sample Questions:

1. DRAG DROP You support a customer who
is deploying Microsoft Lync
Server 2013. The customer has completed deployment of the following components:
-A Lync Standard Edition Server,
-A Lync Edge Server,
-A media gateway connected to a Tl trunk,
-Appropriate rules for reverse proxy, and
-An Office Web App server with Microsoft SharePoint 2012.
Neither federation nor external access is enabled.
The customer installs a number of Lync 2013 clients on pilot user computers that are located inside their network. No one is able to access the Lync server from outside the network.
The pilot users report the following issues:
-When they make calls to local numbers, the calls do not work. An announcement states that they must not dial 1 to make a local call.
-When they make calls to long distance numbers, the calls connect, but the other end user reports that the caller's number does not appear correctly.
-When they receive long distance calls from outside, the caller ID information displayed in Lync does not match the caller's contact information.
You need to ensure that users in the customer's network can successfully have calls with users outside the network. You open the Voice Routing tab on the Lync
Server Control Panel as shown in the exhibit. (Click the Exhibit button.)

Which area should you look in to investigate each issue? (To answer, drag the appropriate voice routing area to the correct issue investigation or investigations. Each voice routing area may be used once or not at all. You may need to drag the split bar between panes or scroll to view content.)

2. DRAG DROP
You support a customer whose network environment includes Microsoft Lync Server 2013. Your environment is connected to a third-party network that is supported as a peer IP Private Branch Exchange (PBX) by using direct Session Initiation Protocol (SIP). Both environments are configured properly, and call routing is functional within the two domains.
Media Bypass is configured. Protocols used to specify quality of service (QoS) feedback, synchronization between media streams, and Secure Real-time Transport Protocol (SRTP) are not supported. Users report that they experience poor audio quality when calling public switched telephone network (PSTN) numbers. You need to improve call quality when calling PSTN numbers. Which PowerShell cmdlet should you use with each parameter? (To answer, drag the appropriate cmdlet to the correct parameter or parameters. Each cmdlet 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.)

3. Your network environment includes Microsoft Lync Server 2013. You configure a Session Initiation Protocol (SIP) trunk to point to a Lync Mediation Server from an internet service provider (ISP). Media bypass is disabled. You attempt to forward calls to a mobile phone and receive the following message: "Cannot complete the transfer." You need to be able to forward calls to mobile phones. Which cmdlet should you use?

A) Set-CsTrunkConfiguration -EnableReferSupport $False
B) Set-CsTrunkConfiguration -EnableBypass $True
C) Set-CsTrunkConfiguration -EnableSessionTimer $True
D) Set-CsTrunkConfiguration -RTCPActiveCalls $True

4. 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) Dynamic Host Configuration Protocol (DHCP) options on the branch DHCP server
C) DNS settings on the gateway
D) The domain controller at the branch office

5. You are a member of the CsAdministrator group that supports the Microsoft Lync datacenter for the Contoso company. The datacenter consists of one pool that is running Lync 2013. Contoso has a second Active Directory Domain Services (AD DS) site with a domain controller. The Lync server pool fails. You need to recover the Central Management Store (CMS) and users. Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)

A) Run the Move-CsDatabase and Set-CsManagementServer cmdlets.
B) Create a Backup pool.
C) Run the New-CsRegistrarConfiguration cmdlet.
D) Run the Install-CsDatabase and Move-CsManagementServer cmdlets.
E) Run the Invoke-CsPoolFailover cmdlet.
