Onsite inventories and staff interviews is correct because locating offline assets requires physical inspection and local knowledge that cannot be obtained by networked or cloud tools.

Onsite inventories and staff interviews allow teams to walk through offices, storage rooms, and records facilities to identify paper records, removable media, and standalone devices that are not connected to a network. Interviews with staff reveal where critical records are kept and who is responsible for them, and they help uncover informal or forgotten assets that do not appear in any automated inventory.

Social engineering exercises are incorrect because they are methods for testing human behavior and security awareness rather than systematic discovery of physical assets. Using social engineering might incidentally reveal locations but it is not an appropriate or reliable inventory technique.

Cloud Asset Inventory is incorrect because it focuses on cloud resources and services that are managed online. Cloud inventories do not track paper records or standalone devices that remain offline and physically located in offices or storage facilities.

Automated network scanning tools are incorrect because they only detect devices that are connected to a network. Standalone devices and paper records will not respond to scans, and so network tools will miss those offline assets.
