Question 10

A company is migrating a legacy on-premises application to AWS. The application consists of a web server, an application server, and a MySQL database. The company has already migrated the web and application servers to EC2 instances in a VPC. The database is still on-premises. The application currently connects to the database using a JDBC connection string with the on-premises IP address. The company wants to minimize changes to the application code. The network team has established an AWS Direct Connect connection between the on-premises data center and the VPC. The security team requires that traffic between the application and the database be encrypted in transit. The database is not publicly accessible. The migration plan includes moving the database to Amazon RDS for MySQL in the same VPC after the initial cutover. During the migration testing phase, the application team reports that the application can connect to the on-premises database but performance is slower than expected. CloudWatch metrics show high latency on the database connections. The application uses a connection pool with 100 connections. Which solution should the solutions architect recommend to improve performance while minimizing application code changes?

Accepted Answer

Deploy an Amazon RDS for MySQL read replica in the same Region and direct read traffic to it. Option C is correct because deploying an RDS read replica in the same Region reduces latency for read-heavy workloads. Option A (increase connections) may exacerbate issues. Option B (enable Multi-AZ) does not reduce latency. Option D (DMS ongoing replication) does not improve read performance.

Answer

Increase the connection pool size to 200 and enable connection multiplexing

Answer

Use AWS Database Migration Service to set up ongoing replication from on-premises to RDS

Answer

Enable Multi-AZ on the RDS instance

Question 11

A retail company is migrating its on-premises e-commerce application to AWS. The application currently runs on a single server with a MySQL database. The company wants to minimize operational overhead and improve scalability. Which migration strategy should be used?

Accepted Answer

Rehost the application on Amazon EC2 and use Amazon RDS for MySQL.. Option A is correct because lift-and-shift (rehosting) is the fastest way to migrate with minimal changes, reducing operational overhead. Option B is wrong because refactoring takes more time. Option C is wrong because re-platforming still requires modifications. Option D is wrong because repurchasing would involve changing the application.

Answer

Re-platform the application to use AWS Elastic Beanstalk and Amazon RDS.

Answer
