The answer is Aurora Zero-ETL integration with Amazon Redshift. This solution is correct because it enables complex analytical queries on transactional data without impacting Aurora’s performance by automatically replicating data to Redshift in near real-time, eliminating the need for extract, transform, and load pipelines. On the AWS Certified Database Specialty DBS-C01 exam, this scenario tests your understanding of offloading analytics to a separate, optimized engine while preserving transactional integrity—a common trap is choosing read replicas or ElastiCache, which fail to handle heavy analytical workloads without degrading performance. The key memory tip: think “zero-ETL” as zero impact on Aurora, with Redshift doing the heavy lifting for analytics offload.
DBS-C01 Workload-Specific Database Design Practice Question
This DBS-C01 practice question tests your understanding of workload-specific database design. 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 financial services company uses Amazon Aurora MySQL-Compatible Edition for transaction processing. They need to run complex analytical queries on the same data without impacting transactional performance. Which solution meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Aurora Zero-ETL integration with Amazon Redshift
Aurora Zero-ETL integration with Amazon Redshift allows you to run complex analytical queries on transactional data without impacting Aurora's performance. It eliminates the need for extract, transform, and load (ETL) pipelines by automatically replicating data from Aurora to Redshift in near real-time, ensuring that analytical workloads are offloaded to a separate, optimized analytics engine.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use Aurora Zero-ETL integration with Amazon Redshift
Why this is correct
Zero-ETL integration allows Redshift to query Aurora data directly without impacting performance.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable Performance Insights and use RDS Proxy
Why it's wrong here
Performance Insights is monitoring; RDS Proxy is for connection pooling.
✗
Export data to Amazon S3 and query with Athena
Why it's wrong here
Export process can be complex and not real-time.
✗
Create an Aurora Replica and run analytical queries against it
Why it's wrong here
Aurora Replicas share the same underlying storage; heavy queries can still impact performance.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume an Aurora Replica (Option D) is sufficient for read-heavy analytics, but they overlook that it still shares the same storage subsystem and can cause I/O contention and replication lag under heavy analytical loads.
Detailed technical explanation
How to think about this question
Aurora Zero-ETL integration uses a change data capture (CDC) mechanism to stream transactional changes from Aurora to a Redshift managed storage layer, enabling sub-minute data freshness without custom pipelines. Under the hood, Redshift's massively parallel processing (MPP) architecture and columnar storage allow complex aggregations and joins to run efficiently, while Aurora remains dedicated to OLTP workloads. This is particularly valuable for financial services that need real-time analytics on transaction data without degrading customer-facing application performance.

Real-world example
How this comes up in practice
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.
