You are a messaging professional.

Your company has deployed Microsoft Exchange Server 2007 computers. The company plans to implement Edge Transport servers. The Edge Transport servers will be deployed on a perimeter network. The Edge Transport servers must be configured to use external servers for name resolution.

You need to configure the ports that the external firewall will require for inbound and outbound access.

Your solution must also reduce the effort required to configure the Edge Transport servers.

What should you do to configure the ports that the external firewall will require for inbound and outbound access?

A.
Configure the firewall to allow inbound access on TCP port 25 and outbound access on UDP ports 50389
and 50636.

B.
Configure the firewall to allow both inbound and outbound access on TCP port 25 and outbound access on
TCP and UDP port 53.

C.
Configure the firewall to allow inbound and outbound access on TCP port 25 and outbound access on TCP
ports 50389 and 50636.

D.
Configure the firewall to allow inbound and outbound access on TCP port 25 and outbound access on all
dynamic TCP ports greater than 1023.
