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
✓
Amazon Kinesis Data Streams
Amazon Kinesis Data Streams can ingest clickstream data in near real-time. Option D is correct because Amazon Kinesis Data Firehose can deliver that streaming data to destinations like S3. Option B is wrong because SQS is a message queuing service, not a streaming ingestion service. Option C is wrong because S3 is a storage service, not a real-time ingestion service. Option E is wrong because DynamoDB is a NoSQL database, not a streaming ingestion service.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon Kinesis Data Streams
Why this is correct
Amazon Kinesis Data Streams can ingest clickstream data in near real-time, making it suitable for the pipeline.
- ✗
Amazon Simple Queue Service (SQS)
Why it's wrong here
Amazon SQS is a message queuing service, not designed for streaming ingestion of large volumes of data in near real-time.
- ✗
Amazon S3
Why it's wrong here
Amazon S3 is an object storage service, not a real-time data ingestion service; it is typically used as a destination for data.
- ✓
Amazon Kinesis Data Firehose
Why this is correct
Amazon Kinesis Data Firehose can reliably load streaming data into data stores and analytics tools, such as S3, providing near real-time delivery.
- ✗
Amazon DynamoDB
Why it's wrong here
Amazon DynamoDB is a NoSQL database, not a streaming ingestion service; it is used for storing and retrieving data, not for ingesting streaming data.

| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
