HOTSPOT
You are the Office 365 administrator for your company. You manage an on-premises Microsoft
Exchange Server 2003 environment that has 500 users and an externally-hosted Exchange
environment that has 500 users. The hosted Exchange environment does not allow Outlook
Anywhere connectivity. You do not have administrative access to all mailboxes in the hosted
environment.
You plan to migrate and consolidate both environments into Office 365. You have the following
migration requirements:
Migrate on-premises mailboxes in batches by department.
Migrate email, calendar, and contact items from the on-premises environment.
Migrate only email from the hosted environment.
In the table below, identify the migration type that must be used for each environment. Make only
one selection in each column. Each correct selection is worth one point.
Answer: 
Explanation:
onprem exchange > staged migration, remove move(hybrid) is not supported on Exchange 2003
hosted change environment > IMAP migrationhttp://technet.microsoft.com/en-GB/library/jj863291(v=exchg.150).aspx
I disagree. The requirements say that I don’t have administrative access to all mailboxes in the hosted environment.
On a Staged Migration there is the following requirement:
“Administrators can access email – To migrate email, you need access to the user mailboxes in your source email system.”

Another point is that the Staged Migration is recommended for more than 2,000 users, and the question states that we have 500 users on-premises.
So, I think the right answer is On-premises Exchange -> Cutover migration.
What do you guys think?
Luiz you missed the part “Migrate on-premises mailboxes in batches by department.” which will require a staged migration and prevent a cutover migration.
Answer provided is correct.
The answer is correct. “You do not have administrative access to all mailboxes in the hosted
environment.” refers to externally-hosted Exchange not on-premises exchange server 2003.
In IMAP migration if you don’t have administrative permission to a mailbox you would need that particular mailbox username and password to perform the migration. See post here https://technet.microsoft.com/en-NZ/library/jj898489(v=exchg.150).aspx
