- A
Azure AD Connect
Why wrong: Azure AD Connect synchronizes user identities and passwords but does not migrate mailbox data. It is necessary for hybrid identity but not for mailbox migration.
- B
Exchange Admin Center (EAC) migration dashboard
The EAC migration dashboard supports several migration types (cutover, staged, hybrid) and provides batch management, status reports, and error logs. It is the recommended Microsoft tool for migrating on-premises mailboxes to Exchange Online.
- C
Third-party migration tool (e.g., BitTitan MigrationWiz)
Why wrong: While third-party tools are available, the question specifically asks for a Microsoft-provided tool. The built-in EAC migration dashboard is the correct choice.
- D
IMAP migration
Why wrong: IMAP migration can only migrate email data from IMAP servers, not from on-premises Exchange. It also does not support calendar or contact migration, and lacks granular batch controls.
MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company with 200 on-premises Exchange mailboxes plans to migrate to Exchange Online. They want to use a Microsoft-provided tool that supports granular control over mailbox migrations, allows batch migrations, and provides detailed reporting. Which migration method should the administrator choose?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Exchange Admin Center (EAC) migration dashboard
The Exchange Admin Center (EAC) migration dashboard is the correct choice because it is a Microsoft-provided tool that supports granular control over mailbox migrations (e.g., selecting specific users, setting migration endpoints, and configuring throttling), allows batch migrations with the ability to start, stop, and monitor multiple batches simultaneously, and provides detailed reporting on migration status, errors, and sync progress. This method is specifically designed for migrating on-premises Exchange mailboxes to Exchange Online in a controlled, staged manner, making it ideal for the scenario described.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure AD Connect (identity sync) with a migration tool, or they assume any Microsoft tool (like IMAP migration) is sufficient, but the question specifically requires granular control, batch support, and detailed reporting, which only the EAC migration dashboard provides for on-premises Exchange to Exchange Online migrations.
Detailed technical explanation
How to think about this question
The EAC migration dashboard uses the Move-MailboxRequest cmdlet under the hood, which leverages the Exchange Web Services (EWS) or MRS Proxy to perform remote mailbox moves with support for incremental sync, allowing administrators to perform pre-stage migrations where mailboxes are synced in the background before a final cutover. This method also supports advanced features like migration endpoints for throttling and network optimization, and it provides detailed CSV-based reporting that includes per-mailbox status, error codes, and sync statistics, which is critical for troubleshooting large-scale migrations.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
