Question 565 of 1,672
MLS-C01 Data Engineering Practice Question
A data engineering team needs to process streaming data from thousands of IoT devices. The data must be ingested with low latency and processed in near real-time to detect anomalies. Which AWS service should they use for ingestion?
⚠ Common exam trap
Test-takers frequently confuse Kinesis Data Firehose (which delivers data to destinations with some latency) with Kinesis Data Streams (which is designed for real-time ingestion and processing), often overlooking the 'low latency' and 'near real-time' requirements in the question.
