Answer: D
The answer is D, Replatform. https://docs.aws.amazon.com/prescriptive-guidance/latest/large-migration-guide/migration-strategies.html This strategy is also known as lift, tinker, and shift or lift and reshape. Using this migration strategy, you move the application to the cloud, and you introduce some level of optimization in order to operate the application efficiently, to reduce costs, or to take advantage of cloud capabilities. For example, you might replatform a Microsoft SQL Server database to Amazon RDS for SQL Server. Using this strategy, you might make a few or many changes to the application, depending on your business goals and your target platform. The following are common use cases for the replatform migration strategy: You want to save time and reduce cost by moving to a fully managed service or serverless service in the AWS Cloud.

Which option is a benefit of the economies of scale based on the advantages of cloud computing?
Answer: C
Economies of scale refer to the cost advantages that a business can achieve by increasing its scale of production or operations. In other words, as a company produces more units of a good or service, its average cost of production per unit decreases. This cost reduction occurs because fixed costs are spread over a larger number of units, leading to increased operational efficiency and cost efficiency. A. The ability to trade variable expense for fixed expense: Cloud computing, in general, provides the advantage of paying for resources on a variable (pay-as-you-go) basis rather than a fixed, upfront expense. B. Increased speed and agility: While increased speed and agility are benefits of cloud computing, they are not specifically related to the economies of scale. C. Lower variable costs over fixed costs: This is a key benefit of economies of scale. With cloud computing, as usage increases, the cost per unit of resources tends to decrease due to the efficiency gained from large-scale operations. D. Increased operational costs across data centers: Increased operational costs across data centers would be contrary to the benefits of economies of scale.
