Exam SY0-701 Topic 1 Question 108 Discussion

The best answer is A. The customer is responsible for information and data regardless of the cloud model used.
In cloud environments, a shared responsibility model defines which security duties belong to the cloud provider and which remain with the customer. While the exact split depends on whether the service is IaaS, PaaS, or SaaS, one responsibility that almost always remains with the customer is accountability for their information and data.
The provider secures the cloud infrastructure, but the customer remains responsible for how their data is classified, handled, protected, and governed.
Why the other options are incorrect:
B). The cloud provider is responsible for account and identity management for connected devices.Identity and access management is typically at least partly the customer's responsibility, and often primarily so.
C). The customer and the cloud provider share responsibility for the physical network infrastructure.Physical infrastructure is usually the cloud provider's responsibility, not shared in the way stated here.
D). The cloud provider is responsible for the security of endpoints connected to the infrastructure.Endpoint security is normally the customer's responsibility.
From the SY0-701 perspective, a responsibility matrix in cloud computing reflects the shared responsibility model, and the most consistently true statement here is A.
