The correct answers are A and C. The consumption-based model in cloud computing charges based on actual usage, providing flexibility in budgeting and scalability without the need for large upfront investments. This model also allows businesses to adjust resources according to demand, enhancing operational efficiency and cost control. These features make it an attractive option for companies looking to migrate to the cloud. Options B and D are incorrect because the consumption-based model does not require precise prediction of resource needs (it inherently accommodates fluctuating demand) and security levels are comparable to traditional models, with cloud providers offering various compliance certifications. Option E is incorrect as it describes a feature of dedicated hosting, not the consumption-based model.
