This DVA-C02 practice question tests your understanding of development with aws services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer is designing a system that requires processing of streaming data from IoT devices in real time. The processed data will be stored in an S3 bucket for analytics. Which AWS services should the developer use together to build this solution? (Choose TWO.)
Amazon Kinesis Data Firehose
Firehose can load streaming data into S3 for analytics.
Amazon Kinesis Data Streams
Kinesis Data Streams is used to capture and process streaming data in real time.
AWS Lambda
Why wrong: Lambda can process data but is not a streaming ingestion service.
Amazon S3
Why wrong: S3 is the storage destination, not a processing service.
Amazon SQS
Why wrong: SQS is for message queuing, not real-time streaming.
Answer choices
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 Firehose
The correct answers are A and D. Amazon Kinesis Data Streams ingests streaming data, and Amazon Kinesis Data Firehose delivers that data to S3. Option B is wrong because Lambda is not a streaming ingestion service. Option C is wrong because SQS is for message queues, not real-time streaming. Option E is wrong because S3 is the destination, not the processing service.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon Kinesis Data Firehose
Why this is correct
Firehose can load streaming data into S3 for analytics.
Related concept
Static NAT maps one inside address to one outside address.
Amazon Kinesis Data Streams
Why this is correct
Kinesis Data Streams is used to capture and process streaming data in real time.
Related concept
Static NAT maps one inside address to one outside address.
AWS Lambda
Why it's wrong here
Lambda can process data but is not a streaming ingestion service.
Amazon S3
Why it's wrong here
S3 is the storage destination, not a processing service.
Amazon SQS
Why it's wrong here
SQS is for message queuing, not real-time streaming.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DVA-C02 NAT questions on configuration and troubleshooting.
