The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why A is Correct: Business Critical matches the expected DP-300 administration action. Business Critical provides low-latency local SSD storage and high availability for demanding workloads, but it is usually more expensive than necessary for bursty idle workloads. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You are planning a solution that will use Azure SQL Database.
Why B is Wrong: Premium is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It would solve a neighboring problem, but not the deployment, sizing, or migration requirement in this item.
Why C is Wrong: Hyperscale is designed for very large databases and fast scale-out storage architecture, not merely for intermittent CPU bursts. It mismatches the target platform, migration method, compute tier, or deployment model described in the scenario, so it would not satisfy the workload as stated.
