All of the locations connect to the each other by using a WAN link. The New York, Toronto, and Chicago
locations connect directly to the Internet.
All client computers run Windows 7 and Office 2010. All servers run Windows Server 2008.
Active Directory Environment
The network contains an Active Directory domain named adatum.local. Adatum.local is the corporate domain
based in the United States. The network contains a domain named Canada.adatum.local. Canada.adatum.local
is the domain for the stores in Canada.
Each location is configured as an Active Directory site.

The main office and both of the distribution centers each has two domain controllers for their respective
domain. All of the other locations have one domain controller for their respective domain. All of the domain
controllers are global catalog servers.
Exchange Infrastructure
The main office and the distribution centers each have three servers that have Exchange Server 2007 installed.
The servers have the following configurations:
Two of the servers have cluster continuous replication (CCR) deployed
One of the servers has the Client Access server role and the Hub Transport server role installed
Each store contains a server that has Exchange Server 2007 installed. Each server has mailboxes for active
users and mailboxes for inactive users. Each server has approximately 50 mailboxes.
Remote users access Outlook Web Access by using a namespace of mail.adatum.com, which resolves to the
Client Access server in the New York office.
Requirements
Planned Changes
The company plans to implement the following changes:
Migrate all of the mailboxes in the main office and the distribution centers to Exchange Server 2013.
Integrate a new telephone system to the Exchange Server 2013 organization.
Deploy a standalone certification authority (CA) that will be used to issue all of the certificates for themessaging
infrastructure.
Technical Requirements
The company identifies the following technical requirements:
Hardware costs must be minimized whenever possible.
The impact on end users if a site fails must be minimized.
Voice mail traffic between the telephone system and the Exchange Server environment must be encrypted.
Each user must be able to access the internal resources and their mailbox by using a single user account.
Compliance Requirements
After a security review, the company identifies the following compliance requirements for the new Exchange
Server environment:
All administrative changes made to the mailboxes must be tracked.
The legal department must be able to search for messages in all of the mailboxes.
Users must be prevented from sending email during an upcoming statutory holiday.
All store managers must be prevented from permanently deleting email messages from their Inbox.
All email messages must be archived for a minimum of five years to meet regulatory requirements.
Management occasionally sends the staff internal memos that contain confidential information, such as
sales figures. The memos must be protected so that unauthorized users cannot read the memos and
internal users cannot forward the memos to external recipients.
The users in the research department must be able to send email to anyone in the organization, but only the
members of a group named Execs must be able to send email to the research users. All other users must
be notified that email sent to the research users will remain undelivered.

You need to recommend a solution to ensure that during the planned migrations, all Autodiscover requests are
processed by the Exchange Server 2013 Client Access servers.
What should you recommend?

A.
On the Exchange Server 2007 Client Access servers, modify the AutodiscoverServiceInternalURI.

B.
On the Exchange Server 2007 Client Access servers, modify the ExternalURL value of the Autodiscover
virtual directory.

C.
On the Exchange Server 2013 Client Access servers, modify the ExternalURL value of the Autodiscover
virtual directory.

D.
On the Exchange Server 2013 Client Access servers, modify the AutodiscoverServiceInternalURI.

Explanation:
The Exchange Server 2007 Client Access servers must be configured to use the Exchange Server 2013 Client
Access server. We do this by setting the AutodiscoverServiceInternalURI property.
