You support Microsoft Lync Server 2013 servers in your customer's company network. You enable federation with a public instant messaging (IM) provider. Users of the public IM provider are unable to participate in IM conversations in your customer's organization. You need to ensure that the users of the public IM provider are able to participate in IM conversations. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A.Create a federated user access policy.
• B.Enable partner domain discovery.
• C.Create a federation and public IM connectivity policy.
• D.Enable an archiving disclaimer to federated partners.

You support a Microsoft Lync Server 2013 datacenter that has:
-Two paired Front End pools named ConPoolOl and ConPool02 running Microsoft Lync Server 2013.
-65,000 users.
Meeting content is stored on ConPoolOl.
The servers that are running ConPoolOl suffer a catastrophic failure. You take the following steps:
-Failover users to ConPool02.
-Correct the failure on ConPool01.
-Failback the users to ConPool01.
You need to restore meeting content for users. Which cmdlet(s) should you run?

• A.Invoke-CsBackupServiceSync
• B.Invoke-CsPoolFailover PowerShell
• C.Test-CsDatabase cmdlet, and then Get-CsUserDatabaseState
• D.Get-CsDatabaseMirrorState crndlet and then Invoke-CSManagementServerFailover PowerShell

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?

• A.Update the certificate chain on the Exchange CAS.
• B.Remove the Lync Client certificates for the test user from the Lync server.
• C.Reissue the current Exchange CAS server certificate and bind to the IIS service.
• D.Update the Lync server internal web services certificate on each front-end pool server.

HOTSPOT Your customer supports a Microsoft Lync Server 2013 environment. Users are unable to add a federated user to an AV conference. The affected users can view the federated user's presence, and the internal users' External Access Policy is configured to allow communication with federated users. You attempt to initiate a Telnet session to TCP port 5062 from your Lync Server 2013 Front End Server to your Lync Server 2013 Edge Server's internal interface, but you receive an error message that includes "Could not open a connection to the host, on port 5062: Connect failed." You decide to work with the network team to ensure that the Lync Server 2013 environment has the appropriate connectivity to ensure media path negotiation and media flow between the front end server and the Edge server. You need to ensure that users are able to add federated users to an AV conference. Which network ports should you confirm are open on the Lync Server 2013 Front End Server and on the Lync Server 2013 Edge Server? To answer, select the appropriate server or servers for each port in the answer area.

正解：

Explanation:

*STUN/MSTURN/TCP/443 / Edge Server internal interface / Fallback path for A/V media transfer between internal and external users, Survivable Branch Appliance or Survivable Branch Server if UDP communication cannot be established, TCP is used for file transfer and desktop sharing
*STUN/MSTURN/UDP/3478 / Edge Server internal interface / Preferred path for A/V media transfer between internal and external users, Survivable Branch Appliance or Survivable Branch Server
*5061 Access/SIP(MTLS)/TCP/5061 For federated and public IM connectivity using SIP
*5062 SIP/MTLS/TCP/5062 Authentication of A/V users (A/V authentication service) from Front End Server or Front End pool IP address or any Survivable Branch Appliance or Survivable Branch Server using this Edge Server

You support a customer whose network environment includes Microsoft Lync Server 2013 Standard deployed with an Edge Server that is connected to the Internet. All users have Lync Mobile installed on their Windows mobile devices. Users report that they receive instant messages only when the Lync Mobile app is active in the foreground. 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.)

• A.Set up hosting provider federation between your organization and the Push Notification Service at Lync Online.
• B.Enable Push Notifications and Federation from the Lync Server Management Shell.
• C.Open port 5223/TCP outbound on the company firewall.
• D.Install the Lync Mobility components on the Edge Server.
• E.Upgrade the Lync 2010 Mobile app on the Windows mobile devices.
