Explanation:
Preparedomain isn't even a correct switch.
You could argue that preparelegacyexchangepermissions is also correct as this would be the first switch you would run if running them individually, followed by prepareschema.

However preparead will run preparelegacyexchangepermissions and prepareschema if it detects they have not been run.

Explanation:
Ex 2000 is not supported in an Exchange 2010 organization.

Explanation:
The key to this question is the fact that you must use the minimum amount of administrative effort.
Microsoft Technet therefore gives us the answer, as follows:

The Client Access server role can co-exist with Exchange 2007 Client Access servers. Before you upgrade the first Active Directory site, you must install Exchange 2007 Service Pack 2 (SP2) on all Exchange 2007
Client Access servers within your organization. You can add an Exchange 2010 Hub Transport server to an existing Exchange organization after you successfully deploy Exchange 2010 Client Access servers.
After you introduce Exchange 2010 Hub Transport servers to your Exchange 2007 environment, you still need to maintain your Exchange 2007 Hub Transport servers. Exchange 2010 Mailbox servers can only communicate with Exchange 2010 Hub Transport servers, and Exchange 2007 Mailbox servers can only communicate with Exchange 2007 Hub Transport servers. When a message is sent from a mailbox on an Exchange 2010 Mailbox server to a mailbox on an Exchange 2007 Mailbox server, the message is first submitted to the closest Exchange 2010 Hub Transport server in the site.

This server then relays the message to an Exchange 2007 Hub Transport server in the same site, which finally delivers the message to the Exchange 2007 Mailbox server. The Exchange 2010 Mailbox server role can co-exist with Exchange 2007 Mailbox servers. You can replicate public folder data between Exchange 2010 and Exchange 2007 public folder databases.

Explanation:
The answer to this one cannot be D, as has previously been said, as WinRM does not include Windows Powershell, so you cannot run the ServerManagerCmd.exe command. This means the answer can only be A or B (as WMF contains Powershell).
I have gone for A as there is absolutely no need for MSMQ on the Exchange Server, whereas IIS (for OWA) and RPC over HTTP (for Outlook Anywhere) are very useful.
