CompTIA Data+ DA0-002 (V2) Practice Question

While documenting a Level-1 data flow diagram for an e-commerce platform, you notice a data-flow arrow labeled "Completed Orders" drawn directly from the "Orders Warehouse" data store to the "Shipping Carrier" external entity. Under generally accepted data-flow diagram rules, what revision should be made so that this portion of the diagram is valid?

  • Change the Orders Warehouse symbol from a data store to an external entity so the flow becomes entity-to-entity.

  • Keep the existing symbols but replace the single-headed arrow with a double-headed arrow to indicate bidirectional communication.

  • Insert an intermediate process (for example, "Prepare shipping manifest") between the Orders Warehouse data store and the Shipping Carrier external entity.

  • Remove the data-flow from the diagram and capture the shipment hand-off in supplemental documentation instead.
