A metro moves its Big Data lake to a public cloud. The provider hardens the foundation, yet auditors still ask who classifies resident records and manages staff identities. What shared-responsibility idea applies?
Select an answer to reveal the explanation.
Short Explanation
Cloud is like a secured apartment building: the landlord locks the structure, but tenants still lock their own doors. The provider covers the foundation; the city still owns classifications, identities, and how resident data is used. Handing over the rack does not hand over accountability for the contents.
Full Explanation
Shared responsibility in cloud Big Data separates provider controls on the physical and platform foundation from customer duties for data classification, encryption choices, access policies, and identity lifecycle. Municipal auditors correctly expect the city to retain those data-centric controls even after a lake migration. Treating the provider as sole owner of classification, or assuming identity becomes optional, misunderstands the model. BDPC-level cloud awareness requires both sides of that split.
