A new cloud customer wants to know which responsibility they retain no matter whether they adopt IaaS, PaaS, or SaaS. Which set always stays with the customer?
- ATheir stored data and their accounts and identities Correct
- BThe physical datacentre and the racks within it
- CThe physical network that links the servers
- DThe physical hosts that run the workloads
Why A is correct: Correct. Across the shared responsibility model, data or information stored in the cloud and the accounts and identities of people, services, and devices are listed as always the customer's, irrespective of whether the service is IaaS, PaaS, or SaaS, because only the customer can govern who and what they trust.
Why B is wrong: The physical datacentre is real and tempting because the customer pays for capacity, but the model lists it as always the provider's responsibility, never the customer's.
Why C is wrong: The physical network is a genuine shared-responsibility item, yet the model assigns the physical network to the provider in every service model, not the customer.
Why D is wrong: Physical hosts feel customer-adjacent because workloads run on them, but the model places the physical hosts permanently with the provider regardless of service type.
