The answer is that the mail flow rule will quarantine messages sent to example.com. This is correct because the rule applies the quarantine action to any email where the recipient domain matches example.com, as specified in the condition. In Exchange Online, a mail flow rule with a quarantine action holds the message in the quarantine mailbox for admin review, rather than rejecting or blocking it at the transport layer. On the MS-102 exam, this scenario tests your ability to distinguish between quarantine, reject, and block actions—a common trap is confusing quarantine with a rejection, which would generate a non-delivery report, or with a block, which prevents delivery entirely. Remember that quarantine is a soft hold, not a hard stop. A useful memory tip: “Quarantine is for review, reject is for bounce, block is for silence.”
