Exam DP-201 topic 2 question 50 discussion

DRAG DROP -
You are planning a design pattern based on the Lambda architecture as shown in the exhibit.

Which Azure services should you use for the cold path? To answer, drag the appropriate services to the correct layers. Each service may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:

Suggested Answer:
Layer 2: Azure Data Lake Storage Gen2
Layer 3: Azure Synapse Analytics
Azure Synapse Analytics can be used for batch processing.
Note: Layer 1 = speed layer, layer 2 = batch layer, layer 3 = serving layer
Note 2: Lambda architectures use batch-processing, stream-processing, and a serving layer to minimize the latency involved in querying big data.
