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
✓
Amazon ElastiCache
To modernize the legacy application to use AWS managed services, the company should use Amazon RDS for MySQL to replace the self-managed MySQL database, Elastic Load Balancing to distribute traffic across web/application servers, and Amazon ElastiCache to add caching for improved performance. Amazon EBS is a block storage service, not a managed compute or database service. Amazon Route 53 is a DNS service and not relevant to the application architecture modernization in this context. Amazon EC2 is an unmanaged compute service, which does not align with the goal of using managed services.
