You Are Attempting to Upgrade a Server from Windows Server

Multiple Choice

You are attempting to upgrade a server from Windows Server 2008 R2 to Windows Server 2019 Standard Edition. What must be done in order to accomplish the upgrade?

A) The Windows Server 2019 disc provides a direct upgrade path for Server 2008 R2, so no additional steps are required to perform the upgrade.
B) The server should be updated to the latest service pack for 2008 R2 and then upgraded to Server 2012 R2, after which the server can be upgraded to Server 2019.
C) The server must run a special upgrade while Server 2008 R2 is running, requiring the migration of server roles to the new OS and merging of configuration files.
