Option A (enables the rapid provisioning of resources) is correct because cloud computing allows for quick and flexible scaling of resources to meet demand. Option D (shifts capital expenditures (CAPEX) to operating expenditures (OPEX)) is also correct because cloud computing services are typically offered on a pay-as-you-go basis, converting the need for large capital investments into more manageable operational expenses. Administrative complexity (B) is typically reduced, not increased, with cloud solutions, and cloud and on-premises configurations (C) are not necessarily the same.
