السؤال 340 من 539

كل الأسئلة

A company has deployed a web application on AWS. The company hosts the backend database on Amazon RDS for MySQL with a primary DB instance and five read replicas to support scaling needs. The read replicas must lag no more than 1 second behind the primary DB instance. The database routinely runs scheduled stored procedures. As traffic on the website increases, the replicas experience additional lag during peak load. A solutions architect must reduce the replication lag as much as possible. Which solution will meet these requirements?

الخيارات

  • A Migrate the database to Amazon Aurora MySQL. Replace the read replicas with Aurora Replicas, and configure Aurora Auto Scaling. Replace the stored procedures with Aurora MySQL native functions.
  • B Deploy an Amazon ElastiCache for Redis cluster in front of the database. Modify the application to check the cache before querying the database. Replace the stored procedures with AWS Lambda functions.
  • C Migrate the database to a MySQL database that runs on Amazon EC2 instances. Choose large, compute-optimized EC2 instances for all replica nodes.
  • D Migrate the database to Amazon DynamoDB. Provision a large number of RCUs to support throughput and replace stored procedures with DynamoDB streams.
