You have an Exchange organization. All servers in the organization have Exchange Server 2010
Service Pack 1 (SP1) installed. The Exchange organization contains two Hub Transport servers, two
Client Access servers, and two Mailbox servers. All Exchange servers are located on the internal
network. Your company plans to use Microsoft Exchange Hosted Services for message hygiene. You
need to recommend changes to the Exchange organization to meet the following requirements:
• Ensure that the company can send e-mail messages if a single server fails.
• Ensure that the company can receive e-mail messages if a single server fails.
• Prevent Internet hosts from initiating connections directly to servers on the internal network.
Which of the following changes is the best recommendation? (More than one answer choice may
achieve the goal. Select the BEST answer.)
A.
Move the two Hub Transport servers to the perimeter network. Update the public Mail Exchanger
(MX) records to point to the Exchange Hosted Services servers. Configure Exchange Hosted Services
to forward e-mail to the new servers. Configure the internal firewall to allow communication from
the Hub Transport servers to the internal network. Create an additional Send connector.
B.
Deploy two new Edge Transport servers on the perimeter network.
Update the public Mail Exchanger (MX) records to point to the Exchange Hosted Services servers.
Configure Exchange Hosted Services to forward e-mail to the new servers. Configure the internal
firewall to allow communication from the Edge Transport servers to the internal network. Enable
EdgeSync synchronization.
C.
Deploy two new Hub Transport servers on the perimeter network.
Update the public Mail Exchanger (MX) records to point to the new Hub Transport servers.
Configure the internal firewall to allow communication from the Hub Transport servers to the
internal network.
Create an additional Send connector.
D.
Deploy two new Edge Transport servers on the perimeter network.
Update the public Mail Exchanger (MX) records to point to the new Edge Transport servers.
Configure the internal firewall to allow communication from the Edge Transport servers to the
internal network.
