Single Answer, Multiple Choice

You are the messaging engineer for GeoTrek Corp. Your organization has Exchange Server 5.5, Exchange Server 2000 and Exchange Server 2003 servers in the messaging system. You plan to convert your organization from mixed mode to native mode.

What should you do to prepare your Exchange organization for conversion to native mode?

1. Decommission Exchange Server 2003
2. Decommission Exchange Server 2000
3. Decommission Exchange Server 5.5
4. Run an in-place upgrade on Exchange Server 5.5 to install Exchange Server 2003

Answer:
C. Decommission Exchange Server 5.5

Tutorial:
You should decommission the Exchange Server 5.5 from your Exchange organization to prepare your Exchange organization for conversion to native mode. A mixed mode Exchange organization can contain Exchange Server 2003 (or earlier) versions. In native mode, the Exchange organization can only contain Exchange Server 2000 (or later) versions. After you have removed Exchange Server 5.5 and all versions of Exchange Server before Exchange 2000, you should use Exchange System Manager to switch your Exchange organization to native mode. You have to convert your Exchange organization to native mode if you plan to install Exchange Server 2007 in your messaging system because Exchange Server 2007 does not support mixed mode and can only be installed in native mode.

You should not decommission Exchange Server 2003to prepare your Exchange organization for conversion to native mode. Exchange organization in native mode supports Exchange Server 2000 (or later) versions. You should remove Exchange Server 5.5 (or earlier) versions of Exchange to convert your Exchange organization to native mode.

You should not decommission Exchange Server 2000 to prepare your Exchange organization for conversion to native mode. The Exchange organization in native mode supports Exchange Server 2000 (or later) versions. You should remove Exchange Server 5.5 (or earlier) versions of Exchange to convert your Exchange organization to native mode.

You cannot run an in-place upgrade on Exchange Server 5.5 to install Exchange Server 2003 to prepare your Exchange organization for conversion to native mode. To upgrade your organization from Exchange Server 5.5 to Exchange Server 2003, you must install Exchange Server 2003 on a separate computer and then decommission the Exchange Server 5.5 from your organization.
