MS-900 Describe cloud concepts Practice Question
A service owner is comparing Microsoft 365 capabilities and needs to understand which security tasks Microsoft handles and which remain with the customer. Cloud concept or benefit best matches this requirement?
⚠ Common exam trap
It's easy for candidates to confuse specific security features (like DLP or sensitivity labels) with the overarching responsibility framework, failing to recognize that the shared responsibility model is the foundational concept that explains the division of security tasks.

Correct answer & explanation
✓
Shared responsibility model
The shared responsibility model defines which security tasks are handled by Microsoft (e.g., physical security, hypervisor patching) and which remain with the customer (e.g., user access management, data classification). This directly matches the service owner's need to understand the division of security responsibilities in Microsoft 365.
