This MS-900 practice question tests your understanding of describe cloud concepts. 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. A key principle to apply: managed cloud storage shifts infrastructure responsibility to the cloud provider.. 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 tenant administrator is advising a department that wants to stop maintaining local file servers by using managed cloud storage. Cloud concept or benefit best matches this requirement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reduced infrastructure maintenance
Option B is correct because moving from on-premises file servers to managed cloud storage (e.g., Microsoft OneDrive, SharePoint Online, or Azure Files) eliminates the need for the department to handle hardware procurement, patching, backups, and physical maintenance. This directly aligns with the cloud benefit of reduced infrastructure maintenance, a core concept in the MS-900 exam's 'Describe cloud concepts' domain.
Key principle: Managed cloud storage shifts infrastructure responsibility to the cloud provider.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Sensitivity labels
Why it's wrong here
Sensitivity labels classify and protect content, not this cloud concept.
✓
Reduced infrastructure maintenance
Why this is correct
Managed cloud storage reduces the need to operate local file server infrastructure.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Managed cloud storage shifts infrastructure responsibility to the cloud provider.
✗
Microsoft Planner
Why it's wrong here
Planner manages tasks and does not describe this cloud model or benefit.
✗
Data Loss Prevention (DLP)
Why it's wrong here
DLP protects sensitive information from inappropriate sharing, not this cloud concept.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse security or compliance features (like sensitivity labels or DLP) with cloud benefits, when the question specifically asks for the cloud concept or benefit that matches reducing local server maintenance.
Detailed technical explanation
How to think about this question
Managed cloud storage services like SharePoint Online or Azure Files offload storage infrastructure management to Microsoft, including automatic failover, encryption at rest (using BitLocker and DKM), and geo-redundancy. Under the hood, these services use distributed file systems (e.g., Azure Storage's append-blob architecture) and provide SMB protocol support for Azure Files, enabling seamless migration without ongoing hardware lifecycle management. A real-world scenario is a department migrating from on-premises file shares to SharePoint document libraries, where Microsoft handles patching, backups, and SLA-driven availability.
KKey Concepts to Remember
Managed cloud storage shifts infrastructure responsibility to the cloud provider.
Reduced infrastructure maintenance includes hardware, software, and environmental costs.
Moving from local file servers to cloud storage eliminates on-premises server upkeep.
Microsoft 365 services like SharePoint Online provide managed cloud storage.
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
Managed cloud storage shifts infrastructure responsibility to the cloud provider.
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.
