SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 company is designing a real-time analytics pipeline to process streaming data from IoT devices. The solution must be serverless and handle data transformation before storage. Which combination of services is most cost-effective?
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, AWS Lambda, and Amazon Kinesis Data Firehose to Amazon S3
Option B is correct because Kinesis Data Streams ingests data, Lambda transforms it, and Firehose delivers to S3. Option A (Kinesis Analytics) is for SQL analytics, not transformation. Option C (Kinesis Data Streams to EC2) is not serverless. Option D (SQS to Lambda to S3) misses streaming ingestion.
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
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, AWS Lambda, and Amazon Kinesis Data Firehose to Amazon S3
Why this is correct
Serverless, cost-effective for streaming transformation.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon Kinesis Data Streams, Amazon EC2 instances for transformation, and Amazon S3
Why it's wrong here
EC2 is not serverless and requires management.
✗
Amazon Simple Queue Service (SQS), AWS Lambda, and Amazon S3
Why it's wrong here
SQS is for decoupling, not streaming ingestion.
✗
Amazon Kinesis Data Analytics for real-time SQL and Amazon S3
Why it's wrong here
Kinesis Analytics is for analytics, not transformation.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
What to study next
Got this wrong? Here's your next step.
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 SAP-C02 NAT questions on configuration and troubleshooting.
