DBS-C01 Workload-Specific Database Design Practice Question
Which TWO database design considerations are critical when migrating a high-traffic e-commerce website from Oracle to Amazon Aurora MySQL? (Choose 2.)
⚠ Common exam trap
A common mix-up: candidates assume Aurora Multi-Master is the best choice for high write loads, but the exam tests understanding that Multi-Master introduces conflict resolution overhead and is typically not recommended for standard e-commerce workloads, where a single writer with read replicas is more appropriate.

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
✓
Review and adapt application SQL queries for MySQL compatibility
Oracle and MySQL use different SQL dialects, data types, and functions. Migrating a high-traffic e-commerce application requires reviewing and adapting all SQL queries to ensure compatibility with Aurora MySQL, including handling Oracle-specific features like sequences, hierarchical queries (CONNECT BY), and PL/SQL stored procedures. Failure to do so will cause runtime errors or degraded performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable eventual consistency for read replicas to reduce latency
Why it's wrong here
Aurora provides strong consistency; eventual consistency is not an option.
- ✓
Review and adapt application SQL queries for MySQL compatibility
Why this is correct
Oracle and MySQL differ in SQL syntax.
- ✓
Evaluate the impact of Aurora's storage engine on query performance
Why this is correct
Aurora's storage engine differs from Oracle's.
- ✗
Use Aurora Multi-Master to distribute write load
Why it's wrong here
Multi-Master is an option but not a critical migration consideration.
- ✗
Compress all tables to reduce storage costs
Why it's wrong here
Compression is not automatically available; needs evaluation.
