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 email 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?

Exchanger (MX) record for Server3. Set the priority value to 5.

Exchanger (MX) record for Server3. Set the priority value to 20.
