SAP-C02 Practice Question: Accelerate Workload Migration and Modernization

The company wants to improve scalability and availability while reducing administrative overhead. Which THREE actions should the solutions architect take? (Select 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 MySQL database to Amazon RDS Multi-AZ
Using an ALB and Auto Scaling for web tier improves scalability and availability. Migrating to RDS Multi-AZ reduces overhead and provides high availability. ElastiCache for session caching improves performance, but is not the only option for scalability. EFS is for shared file storage, not needed. Using Spot Instances for all tiers may cause interruptions.
