DRAG DROP You administer Microsoft Lync Server 2013 servers in your customer's company network. All network computers are members of an Active Directory Domain Services (AD DS) domain that is operating in Windows Server 2008 domain functional mode. Client computers have various versions of Office Communicator R2 and the Lync client installed. You enable Lync Server 2013 enhanced presence privacy mode. Several users inform you that their presence and contact information is available to users who have not been authorized to view it. You need to prevent non-authorized users from accessing the personal information of other users. You also need to continue providing Lync access to all users. Which three actions should you perform in sequence? (To answer, move the appropriate three actions from the list of actions to the answer area and arrange them in the correct order.)

Correct Answer:

Explanation:
Box 1: Upgrade Office Communicator to Lync Client
Box 2: Define a new client version policy that prevents Office Communicator from
signing in.
Box 3: Instruct users to sign in to Lync client and restore privacy settings.
Note:
*Lync 2013 and Lync 2010 privacy settings are not honored by previous versions (Microsoft Office Communicator
2007 R2 or Microsoft
Office Communicator 2007). If previous versions of Office Communicator are allowed to sign in, a Lync 2013 user's status, contact information, or picture could be viewed by someone who has not been authorized to view it. Additionally, a Lync 2013 user's privacy settings are reset if he or she later signs in with previous version of Communicator. For these reasons, in a migration scenario, before you enable enhanced presence privacy mode:
*(Box 1) Ensure that every user has Lync 2013 installed.
*(Box 2) Define a client version policy rule to prevent previous versions of Communicator from signing in.
*With enhanced presence privacy mode, users can restrict their presence information so that it is visible only to the contacts listed in their Lync 2013 Contacts list.

DRAG DROP You support Microsoft Lync clients and servers in your customer's company network. All computers are members of a single Active Directory Domain Services (AD DS) domain named contoso.local. The single front-end Microsoft Lync Server 2013 server is configured to support a session initiation protocol (SIP) domain named contoso.com. You configure Lync to support users from a new SIP domain named proseware.net. The users of the new SIP domain report that the Lync client is able to connect to the Lync server only after manual configuration. Users of the Contoso.com SIP domain are able to connect to Lync server automatically, both internally and externally. You need to restore the internal and external automatic discovery features for the users of the proseware.net SIP domain. Which fully qualified domain name (FQDN) should you add to the subject alternative name (SAN) in each certificate request? (To answer, drag the appropriate FQDN to the correct certificate request. Each FQDN 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.)

Correct Answer:

Explanation:

You support a Microsoft Lync Server 2013 environment with open federation for a company named Contoso. Contoso's perimeter network topology is shown in the exhibit. (Click the Exhibit button.)

The public certificates on the external interfaces of the Lync Edge and Reverse Proxy are as follows:

You receive a support ticket that audio calls to federated partners that also use Lync Server 2013 are not working. You need to correct the issue of the failed audio calls. What should you do?

• A.Open the inbound and outbound UDP port 5061 on the external firewall to the Access Edge Service External IP address.
• B.Open the inbound and outbound UDP and TCP port range 50000-59999 on the external firewall to the AV Edge Service External IP address.
• C.Open the inbound and outbound UDP port 3478 on the external firewall to the AV Edge Service External IP address.
• D.Add "contoso.com" as a subject alternative name to the public certificate on the reverse proxy external interface.
• E.Add "lyncdiscover.contoso.com" as a subject alternative name to the public certificate on the reverse proxy external interface.

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

DRAG DROP You support a Microsoft Lync Server 2013 environment.
A customer reports that they are receiving alerts from the voice gateway and that outbound calls are failing due to no trunks being available. You need to diagnose the issue. You decide to collect performance counters to determine the reason that calls are failing. Which
Performance Monitor counter or counters should you select, on which server or servers? (To answer, drag the appropriate counter and server to the correct location or locations in the Solution area. Each voice counter and server 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.)
