SAP-C02 Design for New Solutions Practice Question
A company is designing a solution to process real-time streaming data from IoT devices. The data must be ingested, processed with sub-second latency, and stored for analytics. Which services should the company use? (Choose TWO.)
⚠ Common exam trap
Watch out — candidates often confuse Amazon Kinesis Data Firehose (which has a 60-second minimum buffer) with Kinesis Data Streams for sub-second latency, or they mistakenly think SQS is suitable for streaming ingestion when it is designed for message queuing, not ordered, replayable stream processing.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Lambda
AWS Lambda is correct because it can process streaming data from Amazon Kinesis Data Streams with sub-second latency by subscribing to the stream as an event source. Lambda functions are invoked synchronously with each record, enabling real-time transformations or lightweight analytics before the data is stored.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS Lambda
Why this is correct
Can process records from Kinesis streams in near real-time.
- ✓
Amazon Kinesis Data Streams
Why this is correct
Low-latency ingestion for real-time data.
- ✗
Amazon SQS
Why it's wrong here
SQS is for message queues, not streaming ingestion.
- ✗
Amazon Kinesis Data Analytics
Why it's wrong here
Analytics is for running SQL on streams, not primary ingestion/processing.
- ✗
Amazon Kinesis Data Firehose
Why it's wrong here
Firehose is for loading data to destinations with some latency, not sub-second processing.
