The answer is the Exchange Hybrid Configuration Wizard (HCW). This tool is correct because it automates the complex configuration of coexistence features between on-premises Exchange and Exchange Online, handling critical elements like mail flow routing, free/busy sharing, and OAuth authentication by generating the necessary send/receive connectors and organizational relationships. On the MS-102 exam, this question tests your understanding of the specific tool used to bridge on-premises and cloud environments during a migration, often appearing as a straightforward scenario where you must distinguish the HCW from other tools like the Migration Endpoint Wizard or Azure AD Connect. A common trap is confusing the HCW with the Exchange Admin Center’s migration tools, but remember that the HCW is for configuring the hybrid deployment itself, not just moving mailboxes. Memory tip: “HCW = Hybrid Coexistence Wizard” — if the scenario involves mail flow and free/busy during a transition, think HCW.
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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 is planning to migrate from on-premises Exchange to Exchange Online and needs to ensure that mail flow can coexist between the two environments during the transition. Which tool should the administrator use to configure this hybrid deployment?
Why wrong: Azure AD Connect synchronizes on-premises directories with Microsoft Entra ID but does not handle hybrid mail flow configuration.
B
Exchange Hybrid Configuration Wizard
This wizard guides through the steps to establish a hybrid relationship between on-premises Exchange and Exchange Online, including mail flow and free/busy sharing.
C
Microsoft 365 Admin Center
Why wrong: The admin center allows management of users and services but does not include tools for configuring hybrid mail routing.
D
Exchange Admin Center
Why wrong: While the EAC can manage many Exchange settings, the hybrid configuration is performed via the dedicated Hybrid Configuration Wizard.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Exchange Hybrid Configuration Wizard
The Exchange Hybrid Configuration Wizard (HCW) is the correct tool because it automates the configuration of coexistence features between on-premises Exchange and Exchange Online, including mail flow routing, free/busy sharing, and OAuth authentication. It generates the necessary connectors and settings to support a hybrid deployment, ensuring seamless mail flow during migration.
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's directory synchronization role with hybrid mail flow configuration, assuming it handles all hybrid setup, when in fact it only syncs objects and does not configure Exchange-specific routing or coexistence.
Detailed technical explanation
How to think about this question
The HCW configures send and receive connectors with specific TLS certificates and authentication mechanisms to enable secure mail routing between on-premises and Exchange Online. It also sets up the Organization Relationship and Intra-Organization Connector for free/busy and mailbox move scenarios, leveraging the Autodiscover service and OAuth 2.0 for cross-premises authentication. In real-world migrations, the HCW must be rerun after any significant certificate or namespace change to maintain coexistence.

→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

Variation 1. A company wants to migrate from on-premises Exchange to Exchange Online. They need to synchronize user mailboxes. Which tool should they use?
Why C: The Exchange Online Hybrid Configuration Wizard (HCW) is the correct tool for migrating on-premises Exchange mailboxes to Exchange Online because it configures the hybrid deployment settings, including the necessary connectors, federation trust, and OAuth authentication, enabling mailbox moves via the New-MigrationBatch cmdlet or the EAC. It orchestrates the synchronization of mailbox data between the on-premises environment and Exchange Online, leveraging the MRS (Mailbox Replication Service) proxy for secure, seamless migration.
Variation 2. 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?
medium
A.Azure AD Connect
✓ B.Exchange Admin Center (EAC) migration dashboard
Why B: 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.
Variation 3. A company needs to migrate several shared mailboxes from on-premises Exchange 2016 to Exchange Online. The company plans to keep some user mailboxes on-premises for now. Which migration strategy should they use for the shared mailboxes?
medium
A.Cutover migration
B.Staged migration
C.IMAP migration
✓ D.Hybrid migration
Why D: A hybrid migration is the correct choice because it allows the coexistence of on-premises Exchange 2016 and Exchange Online mailboxes, enabling the selective migration of shared mailboxes while keeping some user mailboxes on-premises. This approach uses the Hybrid Configuration Wizard to establish a secure connection and synchronize directory objects via Azure AD Connect, supporting mailbox moves with the New-MoveRequest cmdlet.
