Batch workload for the product catalog that is loaded every 24 hours to a data warehouse, streaming workload for online purchases loaded to the warehouse as they occur, and micro batch workload for inventory updates applied after every 1,200 transactions is the correct option.

The product catalog is refreshed once every 24 hours so it matches a batch workload. Batch processing is appropriate for scheduled, bulk transfers to a data warehouse where latency can be higher and throughput is the priority.

Online purchases arrive as individual events and need to be loaded as they occur so they match a streaming workload. Streaming processing supports low latency ingestion and immediate availability of each event in the warehouse.

Inventory updates that are applied after every 1,200 transactions match a micro batch workload because the updates are collected into small frequent batches before being applied. Micro batching gives a balance between throughput and near real time responsiveness for grouped events.

Streaming workload for the product index that is refreshed every 24 hours to a data warehouse, micro batch workload for customer purchases that are pushed to the warehouse as they occur, and batch workload for inventory reconciliations that are processed after every 1,200 transactions is incorrect because the product index refreshed daily is a batch pattern rather than streaming, customer purchases that arrive as they occur need streaming rather than micro batching, and inventory reconciliations triggered every 1,200 transactions are a micro batch pattern rather than a large scheduled batch.

Micro batch workload for the product catalog that is refreshed every 24 hours to a data warehouse, batch workload for online purchases that are accumulated before loading, and streaming workload for inventory updates that are emitted after every 1,200 transactions is incorrect because a product catalog updated daily is a batch workload and not micro batch, online purchases that are accumulated before loading describe batch processing rather than streaming, and inventory updates emitted after a count of transactions are better described as micro batch rather than continuous streaming.
