Your company has a domain controller named Server1 that runs Windows Server 2008 R2 and the DNS server role. A server named Server2 runs Windows Server 2003 and Microsoft Exchange Server 2007.
The company wants to deploy a new Exchange server named Server3 to receive all inbound e- mail traffic.
You need to configure DNS to direct incoming e-mail traffic to the Exchange servers. You also need to ensure that higher priority is given to Server3.
What should you do?
A. Set the priority value of the Server2 Mail Exchanger (MX) record to 20. Create a new Mail Exchanger (MX) record for Server3. Set the priority value to 5.
B. Set the priority value of the Server2 Mail Exchanger (MX) record to 5. Create a new Mail Exchanger (MX) record for Server3. Set the priority value to 20.
C. Create a new Service Location (SRV) record in the domain for Server3. Set the port number value to 25. Configure the priority setting to 20.
D. Create a new Service Location (SRV) record in the domain for Server3. Set the port number value to 110. Configure the priority setting to 5.
