DRAG DROP
You have an Exchange Server 2010 Service Pack 1 (SP1) organization named contoso.com.
Remote users connect to the organization by using Microsoft Outlook 2010. Your network includes
four servers. The servers are configured as shown in the following table.
You create a Hosts file on Server3 and Server4 that contains the IP addresses and server names of
Server1 and Server2. You need to recommend which DNS records must be created to meet the
following requirements:
• Support Edge Subscriptions.
• Provide load balancing for email traffic received from the Internet.
• Ensure that email can be received from the Internet if a single Edge Transport server fails.
What should you do?
To answer, drag the appropriate DNS records to the correct DNS zone in the answer area.
Answer: 
Explanation:
This solution makes no sense and certainly does not meet the requirements of the Question.
• Support Edge Subscriptions.
• Provide load balancing for email traffic received from the Internet.
• Ensure that email can be received from the Internet if a single Edge Transport server fails.
To support load balancing of the edge servers you will need to create external MX records for both
Edge Servers – this will also insure that email can be received if a single edge server fails. To support
Edge Subscriptions you will need to create A records on the internal network.
