You need to identify the minimum number of access numbers and dial plans required for the planned configuration.
How many access numbers and dial plans should you identify? To answer, select the appropriate number of access numbers and dial plans in the answer area.

QUESTION 46
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: ACE
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
Reference: What DNS records are required for Office 365 Lync
