AZ-305 Design infrastructure solutions Practice Question
A multinational organization is designing a Microsoft 365 deployment for 10,000 users. The organization requires that all users have a consistent experience and that desktop settings follow users across devices. The solution must also support offline access to files and automatic sync. Which Microsoft 365 service should the organization use?
⚠ Common exam trap
Watch out — candidates often confuse Enterprise State Roaming (which roams Windows settings) with OneDrive for Business (which roams files and provides offline sync), leading candidates to pick Option C when the question explicitly requires offline file access and automatic sync.
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
✓
OneDrive for Business
OneDrive for Business is the correct choice because it provides per-user cloud storage with offline file access via Files On-Demand and automatic sync through the OneDrive sync client. It also enables desktop settings (such as desktop, documents, and pictures folders) to follow users across devices via Known Folder Move, ensuring a consistent experience. This directly meets the requirements for offline access, automatic sync, and cross-device settings roaming.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Entra ID
Why it's wrong here
Microsoft Entra ID is the tenant's identity provider and authentication service, but it does not contain any file storage or settings-synchronization pipeline. While Entra ID can issue tokens that authorize access to OneDrive or Intune, it never moves or caches user file content, nor does it roam Windows OS settings to other devices. Because the organization's requirement depends on offline file access and sync, Entra ID alone is insufficient.
- ✗
Microsoft Intune
Why it's wrong here
Microsoft Intune is an enterprise mobility management (MDM/MAM) service that enforces device compliance, deploys apps, and delivers configuration profiles, but it has no built-in file synchronization engine or offline file cache. Intune can be used to configure OneDrive policies such as Known Folder Move, yet the actual byte-level sync is performed by the OneDrive sync client. Since Intune does not store or replicate user data on its own, it cannot meet the offline file access and sync requirements by itself.
- ✗
Enterprise State Roaming
Why it's wrong here
Enterprise State Roaming (ESR) leverages Entra ID to synchronize Windows settings such as language, theme, and Microsoft Edge favorites across devices, but it does not synchronize the content of user data files. ESR only roams settings and app metadata—it never creates local copies of documents or folders for offline use. The scenario explicitly requires offline file access and folder sync, which ESR is technically incapable of delivering, so it is not the correct solution.
- ✓
OneDrive for Business
Why this is correct
OneDrive for Business provides a full client-side sync engine that replicates files from SharePoint Online to the local disk, enabling true offline access and background re-synchronization when connectivity returns. Its Known Folder Move feature redirects Windows known folders—Documents, Desktop, and Pictures—into OneDrive, allowing user files to roam seamlessly across multiple devices. Together with Files On-Demand, OneDrive meets both offline access and user data sync, making it the only listed option that satisfies the stated requirements.
