SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company runs a critical application on Amazon RDS for MySQL. The database size is 500 GB and growing. The application experiences high write latency during peak hours. A Solutions Architect needs to improve write performance with minimal downtime. Which THREE actions should the architect take? (Choose three.)
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
✓
Migrate the database to Amazon Aurora with MySQL compatibility.
Migrating to Amazon Aurora (A) improves write performance because Aurora uses a distributed storage subsystem with better throughput and lower latency than standard RDS for MySQL. Changing the storage type to Provisioned IOPS (D) guarantees consistent low-latency I/O, directly improving write performance. Increasing allocated storage (E) increases the baseline IOPS for gp2 volumes, which can reduce write latency under high load. Option B (read replica) offloads read traffic but does not help write performance. Option C (Multi-AZ) provides high availability but does not improve write 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.
- ✓
Migrate the database to Amazon Aurora with MySQL compatibility.
Why this is correct
Aurora offers better write throughput and scalability compared to RDS MySQL.
- ✗
Add a read replica to offload read traffic.
Why it's wrong here
Read replicas help with read scaling, not write performance.
- ✗
Enable Multi-AZ deployment for the DB instance.
Why it's wrong here
Multi-AZ provides high availability but does not improve write performance.
- ✓
Change the storage type to Provisioned IOPS.
Why this is correct
Provisioned IOPS provides consistent and higher IOPS, improving write performance.
- ✓
Increase the allocated storage of the DB instance.
Why this is correct
Larger storage volumes have higher baseline IOPS, improving write performance.
