Your company has offices in Tokyo, Bangkok, and Shanghai.
All connections to the Internet are routed through an Internet connection in the Tokyo office. All of
the offices connect to each other by using a WAN link.
The network contains 10 servers that have Exchange Server 2010 installed. The servers are
configured as shown in the following table.
You plan to deploy 10 servers that will have Exchange Server 2013 installed.
The servers will be configured as shown in the following table.
Each site has an IP-PBX that provides telephony services for the mailboxes in that site by using
unsecured SIP over TCP 5070. The IP-PBX uses the same port to connect to multiple SIP peers.
You need to recommend which tasks must be performed to ensure that the Unified Messaging (UM)
features are available to the mailboxes if a single server fails.
Which three actions should you include in the recommendation? (Each correct answer presents part
of the solution. Choose three.)
A.
Configure the Exchange Server 2013 Mailbox servers to listen to unsecured SIP on TCP 5070.
B.
Configure the Exchange Server 2013 Client Access servers to listen to unsecured SIP on TCP 5070.
C.
Install the Client Access server role on the Exchange Server 2013 servers in the Shanghai and
Bangkok offices.
D.
Configure the Exchange Server 2013 Mailbox servers as additional SIP peers that contain new pilot
identifiers.
E.
Configure the Exchange Server 2013 Client Access servers as additional SIP peers that contain new
pilot identifiers.
Explanation:
Note:
* Exchange 2013 Unified Messaging offers administrators:
/ A complete voice mail system
Unified Messaging offers a complete voice mail solution using a single store, transport, and directory
infrastructure. The store is provided by a Mailbox server and forwarding of incoming calls from a
VoIP gateway or IP PBX is handled by a Client Access server. All email and voice mail messages can
be managed from a single management point, using a single administration interface and tool set.
/ An Exchange security model
The Microsoft Exchange Unified Messaging service on a Mailbox server and the Microsoft Exchange
Unified Messaging Call Router service on a Client Access server run as a single Exchange server
account.
Consolidation
* The client access server (CAS) is a server role that handles all client connections to Exchange Server
2010 and Exchange 2013. The CAS supports all client connections to Exchange Server from Microsoft
Outlook and Outlook Web App, as well as ActiveSync applications. The CAS also provides access to
free/busy data in Exchange calendars.
The CAS is one of five server roles in Exchange Server 2007 and Exchange 2010, and one of two
server roles in Exchange Server 2013. It must be installed in every Exchange Server organization and
on every Active Directory (AD) site that has the Exchange mailbox server role installed.
