Amazon (SAA-C03) Exam Questions And Answers page 50
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?
Which changes should be made to the database tier to improve performance?
Migrate the database to Amazon DynamoDB. Use DynamoDB global tables to enable replication to additional Regions.
Deploy MySQL instances in each Region. Deploy an Application Load Balancer in front of MySQL to reduce the load on the primary instance.
Migrate the database to an Amazon Aurora global database in MySQL compatibility mode. Configure read replicas in one of the European Regions.
