You have a Lync Server 2013 infrastructure. The infrastructure contains two sites and is configured for Enterprise Voice. The sites are located in Chicago and Toronto.
Each site has a distinct voice policy, PSTN usage, voice route, and trunk translation rule as shown in the following table.
The voice policy of each site contains the PSTN usage record of its respective site. The voice route of each site uses the trunk assigned to its respective site. The voice route of each site is assigned to the PSTN usage of its respective site.

What should you do?
A. Add the Chicago-AllCalls voice route to the Toronto-Usage PSTN usage record.
B. Add the Chicago-Usage PSTN usage record to the Toronto-VP voice policy.
C. Add the Chicago-PSTN trunk to the Toronto-AllCalls voice route.

You need to recommend changes to the Lync Server 2013 infrastructure to support the planned changes for federation.
Which two changes should you include in the recommendation? (Each correct answer presents part of the solution. Choose two.)
A. In the public DNS zone, create a new alias (CNAME) record named sipfederation.contoso.com.
B. In the public DNS zone, create a new service location (SRV) record named _sipfederationtls._tcp.contoso.com.
C. Deploy a hardware load balancer to the perimeter network.
D. Deploy a Director to the perimeter network.
Answer: B,C Explanation:
* From scenario:
Problem Statements
Users from other companies report that they fail to communicate with the users at Contoso
by using federation.
That's because there is no DNS record for sipinternaltls in the external contoso.com DNS
space.
SRV _sipfederationtls_tcp.contoso.com 5061 The federated partner is running OCS R2,
which doesn't support DNS LB. And the requirements state that they must be able to
communicate if an edge server fails. Only way around that is HLB. Also, question F7
references an HLB.
Q96. - (Topic 12)
You have a Lync Server 2013 infrastructure and a Microsoft Exchange Server 2010 organization.
You have a SIP domain and an SMTP domain named contoso.com.
You recently migrated the on-premise Exchange Server 2010 organization to Microsoft Office 365.
You need to ensure that you can use Unified Messaging (UM) features between the Lync Server 2013 infrastructure and the Office 365 subscription.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)
A. From the Exchange Management Console, create an accepted domain.
B. From the Lync Server 2013 Control Panel, add a hosting provider named exap.um.outlook.com.
C. In the public DNS zone, create a service location (SRV) record named _sipfederationtls._tcp.contoso.com.
D. From the Lync Server 2013 Control Panel, add a hosting provider named exap.um.lync.com.
E. In the public DNS zone, create a service location (SRV) record named _sip._tls.contoso.com.
F. From the Lync Server 2013 Control Panel, click the Enable Communications with Federated Users check box.
Answer: A,C,E
Explanation: A:
* An accepted domain is any SMTP namespace for which a cloud-based e-mail organization sends or receives e-mail.
C, E: To get Office 365 Lync to work with your federated domain, you will need to add some DNS entries. These entries should normally be added to your external DNS. Granted it can also be added to your internal DNS zone if you are doing split brain DNS. To allow your federated domain users to automatically signon to Lync Online you will need 4 DNS records for each of the domains you federate. First you will need 2 SRV dns records created. _sip._tls.<domain> -> pointing to -> sipdir.online.lync.com _sipfederationtls._tcp.<domain> -> pointing to -> sipfed.online.lync.com Next you will need 2 CNAME records created. sip.<domain> -> pointing to -> sipdir.online.lync.com lyncdiscover.<domain> -> pointing to -> webdir.online.lync.com

A. Modify the Client Version Policy allow all versions of office Communicator 2007 R2 to connect
B. Implement Communicator Web Access Server
C. Apply the latest hot fixes to Office Communicator 2007 R2.
