This MS-900 practice question tests your understanding of describe cloud concepts. 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.
During a Microsoft 365 planning workshop, understand which security tasks Microsoft handles and which remain with the customer. 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
✓
Shared responsibility model
The shared responsibility model defines which security tasks are managed by Microsoft (e.g., physical security, hypervisor patching) and which remain with the customer (e.g., user access, data classification). This directly matches the requirement to understand task ownership during a planning workshop. Options like Microsoft Planner, DLP, and sensitivity labels are specific features, not the overarching cloud concept that clarifies responsibility boundaries.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 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.
✗
Sensitivity labels
Why it's wrong here
Sensitivity labels classify and protect content, not this cloud concept.
✓
Shared responsibility model
Why this is correct
The shared responsibility model explains provider and customer responsibilities in cloud services.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse specific security features (like DLP or sensitivity labels) with the overarching shared responsibility model, which is the foundational cloud concept that defines who owns each security task.
Detailed technical explanation
How to think about this question
Under the shared responsibility model, Microsoft is responsible for 'security of the cloud' (physical datacenters, network infrastructure, hypervisor) while the customer is responsible for 'security in the cloud' (identity, devices, data, compliance). For SaaS like Microsoft 365, Microsoft handles the underlying infrastructure and application security, but the customer must configure conditional access policies, MFA, and DLP rules. A real-world scenario: if a user’s credentials are phished, Microsoft’s infrastructure remains secure, but the customer failed to enforce MFA—this illustrates the customer’s responsibility gap.

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 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.
