A company has a multi-tier web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB).The instances are in an Auto Scaling group.The ALB and the Auto Scaling group are replicated in a backup AWS Region.The minimum value and the maximum value for the Auto Scaling group are set to zero.An Amazon RDS Multi-AZ DB instance stores the application’s data.The DB instance has a read replica in the backup Region.The application presents an endpoint to end users by using an Amazon Route 53 record.The company needs to reduce its RTO to less than 15 minutes by giving the application the ability to automatically fail over to the backup Region.The company does not have a large enough budget for an active-active strategy.What should a solutions architect recommend to meet these requirements?Read More →

A solutions architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon.The application is designed to ingest millions of small records per minute from devices all around the world.Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency.The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.The solutions architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB.Which storage strategy is the MOST cost-effective and meets the design requirements?Read More →

A company is running an application on several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer.The load on the application varies throughout the day, and EC2 instances are scaled in and out on a regular basis.Log files from the EC2 instances are copied to a centralAmazon S3 bucket every 15 minutes.The security team discovers that log files are missing from some of the terminated EC2 instances.Which set of actions will ensure that log files are copied to the central S3 bucket from the terminated EC2 instances?Read More →
