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.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Delete old indexes
Why it's wrong here
Deleting indexes will likely decrease, not increase, performance.
- ✓
Create read replicas
Why this is correct
Read replicas offload read operations from the primary instance.
- ✗
Enable multi-AZ failover
Why it's wrong here
Multi-AZ is for high availability, not performance tuning.
- ✗
Increase primary instance size
Why it's wrong here
This is a form of scaling, but read replicas are more efficient for read-heavy workloads.
