question 51

Multiple Choice

A financial services company has a web application that serves users in the United States and Europe. The application consists of a database tier and a web server tier. The database tier consists of a MySQL database hosted in us-east-1. Amazon Route 53 geoproximity routing is used to direct traffic to instances in the closest Region. A performance review of the system reveals that European users are not receiving the same level of query performance as those in the United States. Which changes should be made to the database tier to improve performance?

• A) Migrate the database to Amazon RDS for MySQL. Configure Multi-AZ in one of the European Regions.
• B) Migrate the database to Amazon DynamoDB. Use DynamoDB global tables to enable replication to additional Regions.
