- A
Create a new cloud-only user in the Microsoft 365 admin center and assign a license.
Why wrong: This creates a duplicate identity that is not linked to the on-premises AD, causing management and password issues.
- B
Sync the on-premises user using Azure AD Connect and then assign the license.
This leverages existing identity, synchronizes to the cloud, and then a license is assigned to enable services.
- C
Manually create a user in Microsoft Entra ID with the same name and assign license.
Why wrong: This is similar to creating a cloud-only user and can conflict with sync; not efficient.
- D
Use Azure AD B2B collaboration to invite the on-premises user as a guest.
Why wrong: B2B collaboration is for external users, not employees; would not provide full employee access.
Quick Answer
The answer is to sync the on-premises user using Azure AD Connect and then assign the license. This is the most efficient method because the user already exists in on-premises Active Directory, and Azure AD Connect performs a delta sync that can propagate the identity to Microsoft Entra ID in minutes, avoiding the need to manually recreate the account or send guest invitations. On the MS-102 exam, this scenario tests your understanding of hybrid identity lifecycle management, often appearing as a trap where candidates mistakenly choose to create a new cloud-only user or use B2B collaboration, which introduces unnecessary delays. The core concept is that synchronization preserves the existing on-premises security identifier and attributes, enabling immediate license assignment once the sync completes. Memory tip: think “Sync first, license second” — never rebuild what already exists in your on-premises directory.
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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 new employee has been hired and their account already exists in the on-premises Active Directory. The administrator needs to provide the employee with access to Microsoft 365 services as quickly as possible. What is the most efficient way to enable the user?
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
Sync the on-premises user using Azure AD Connect and then assign the license.
Option B is correct because the user already exists in on-premises Active Directory, and the fastest way to enable Microsoft 365 access is to synchronize that identity using Azure AD Connect. Once synchronized, the user object appears in Microsoft Entra ID (formerly Azure AD), and the administrator can immediately assign a license without re-creating the account. This avoids the delays of manual creation or guest invitations and leverages the existing identity lifecycle.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a new cloud-only user in the Microsoft 365 admin center and assign a license.
Why it's wrong here
This creates a duplicate identity that is not linked to the on-premises AD, causing management and password issues.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the speed of creating a new cloud user (Option A) with the efficiency of leveraging an existing synchronized identity, failing to recognize that synchronization is the intended and fastest path for hybrid environments.

Detailed technical explanation
How to think about this question
Azure AD Connect uses the Directory Synchronization (DirSync) engine to replicate on-premises AD objects to Microsoft Entra ID, with the `sourceAnchor` attribute ensuring a stable link between the two directories. After synchronization, the user's `ImmutableID` matches the on-premises object GUID, enabling seamless password hash sync or pass-through authentication. In a real-world hybrid deployment, this approach allows the administrator to assign an EMS or Microsoft 365 E5 license within minutes of the sync cycle, whereas manual methods would break the identity federation and require additional cleanup.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
