- A
Data sovereignty
Why wrong: Data sovereignty is incorrect because it refers to legal control over data based on geographic location, not a responsibility model for data usage.
- B
Data residency
Why wrong: Data residency is incorrect because it concerns where data is stored physically, not how it is processed under a responsibility model.
- C
Customer data protection
Why wrong: Customer data protection is not a cloud computing responsibility model; it is a policy that governs data usage, but the overarching model is the shared responsibility model.
- D
Shared responsibility model
The shared responsibility model is correct because it is the standard cloud computing model that defines the provider's responsibility for protecting customer data, including how data is used for AI services.

Correct answer & explanation
Shared responsibility model
The shared responsibility model (Option D) is the correct cloud computing responsibility model that applies to data usage by AI services. Under this model, the cloud provider is responsible for protecting the infrastructure and ensuring that the service operates as stated, while the customer is responsible for securing their data and usage. When an AI service like Microsoft 365 Copilot uses customer data, the provider's responsibilities are defined by the shared responsibility model, including commitments to data protection. Option A (Data sovereignty) is incorrect because it refers to legal control based on geography, not responsibility. Option B (Data residency) is incorrect because it concerns storage location, not usage. Option C (Customer data protection) is not a cloud computing responsibility model; it is a policy that governs data usage, but the overarching model is the shared responsibility model.

Customer data protection
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.
