Your Company has Offices in Montreal, New York, and Toronto.
Each Office is configured as an Active Directory Site.
The Montreal Officehas a Site Linkto the New York Office.
The New York Officehas a Site Linkto the Toronto Office.
You have an Exchange Server 2013 Organization that contains five Mailbox Servers. 
The Organization is configured as shown in the exhibit. (Click the Exhibitbutton.)
The Servers in the Montrealand TorontoOffices are members of a Database Availability Group (DAG) named
DAG01.
DAG01contains two Databases name TOMBXand MTLMBX.
MTLMBXis active on EX1and contains all of the mailboxes of the users in the Montreal Office.
TOMBXis active on EX3and contains all of the mailboxes of the users in the Toronto Office.
You need to ensure that all email messages transmitted between the Montreal users and
the Toronto users are routed through EX5.
Which two actions should you perform?
(Each correct answer presents part of the solution. Choose two.)
Exhibit:
A. Run the Set-MailboxTransportService cmdlet on EX5.
B. Make EX5 the Source Server for all of the Send Connectors.
C. Create a separate DAG for each of the Montreal and Toronto Offices.
D. Add EXS to DAG01.
E. Configure the New York Office as a Hub Site.
Answer: AC
Explanation:
A: *Use the Set-MailboxTransportService cmdlet to viewthe Transport Configuration
Information for the Mailbox Transport Service on Mailbox Servers.
* The Mailbox Transport Service runs on all Mailbox Servers and is responsible for
Delivering Messages to and Accepting Messagesfrom Local Mailbox Databases using a
Remote Procedure Call (RPC). The Mailbox Transport Service also uses SMTP to send
messages to and from the Transport Service that runs on all Mailbox Servers for routing
messages to their ultimate destinations.
C: *Database Availability Group (DAG) is a set of up to 16 Microsoft Exchange Server 2013
Mailbox Serversthat provides Automatic, Database-Level Recovery from a Database, Server,
or Network failure. DAGs use continuous replication and a subset of Windows Failover
Clustering Technologies to provide High Availability and Site Resilience. Mailbox Servers in a
DAGmonitor each other for failures. When a Mailbox Server is added to a DAG, it works
with the other Servers in the DAGto provide Automatic, Database-Level Recovery from
Database failures.
