You are designing a streaming data solution that will ingest variable volumes of data.

[Reference:, https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-features#partitions, , , , , , , , Basic Concept: This question tests plan and implement data platform resources in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario., Why D is Correct: Azure Event Hubs Dedicated matches the expected DP-300 administration action. Event Hubs is a streaming ingestion service used to send telemetry to external SIEM or downstream processing systems rather than to build native Azure dashboards. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You are designing a streaming data solution that will ingest variable volumes of data., Why A is Wrong: Event Hubs is a streaming ingestion service used to send telemetry to external SIEM or downstream processing systems rather than to build native Azure dashboards. It applies to a different Azure data-platform design than the one the question is testing., Why B is Wrong: Azure Stream Analytics 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: Azure Data Factory 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 mismatches the target platform, migration method, compute tier, or deployment model described in the scenario, so it would not satisfy the workload as stated., ]
