You need to ingest real-time IoT data into Delta Lake with exactly-once guarantees. Which approach should you use?

Suggested Answer: B Vote an answer

Structured Streaming with checkpointing ensures fault tolerance and exactly-once processing semantics in Databricks. It tracks processed offsets and recovers from failures automatically.
Batch ingestion cannot guarantee real-time processing. Copy activity is not designed for streaming workloads and manual ingestion is not scalable or reliable.
