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 Mailbox servers as additional SIP peers that contain
new pilot identifiers.
C.
Configure the Exchange Server 2013 Client Access servers as additional SIP peers that
contain new pilot identifiers
D.
Configure the Exchange Server 2013 Client Access servers to listen to unsecured SIP on
TCP 5070.
E.
Install the Client Access server role on the Exchange Server 2013 servers in the
Shanghai and Bangkok offices.

Unified Messaging protects against unauthorized requests by retrieving the internal URL of the Unified Messaging Web Services virtual directory that’s located on the Mailbox server and then using the URL to build the list of FQDNs for the trusted SIP peers.
