Your company is planning to migrate to Microsoft Exchange Online. The company employs 1,000
people, each with a mailbox currently located on Exchange 2010 on-premises. You estimate that it
will take a minimum of four weeks to migrate all mailboxes from on-premises Exchange to Exchange
Online.
The company has the following migration requirements:
During the migration, do not change the existing Microsoft Outlook profiles and .ost files used by the
employees.
Ensure that email messages sent between on-premises mailboxes and online mailboxes during the
migration are secure.
Do not send email messages between on-premises mailboxes and online mailboxes over the Internet
in plain text.
You need to select the migration strategy that meets the requirements.

    Answer C is correct

    Cutover migration – for all exchange versions, migrates mailboxes, groups, contacts and calendar, limit to 2000 mailboxes, whole org at one time

    IMAP migration – mostly for 3rd mail systems but no limitation, migrates only emails – 500 000 items per mailbox limit and largest can be 35MB, need direct access to mailboxes

    Remote move migration – available for 2010 and newer, uses the Microsoft Exchange Mailbox Replication Service (MRS)
    (looks same as cross-forest migration to me)
    https://technet.microsoft.com/en-us/library/o365e_hrcmoverequest_fl312271(v=exchg.150).aspx

    Stagged migration – only for 2003 and 2007, needs AD sync, migrates only user and resource mailboxes, no groups no contacts no mailusers
    Mostly used as a permanent mail coexistence between onpremise and online.
