An enterprise wants to build an application for selling concert tickets, with a web layer and an application layer. Which Amazon service should be used so ticket orders are not lost if the application layer fails? - SQS To comply with its disaster recovery requirements, an enterprise is required to store copies of all data in a specific Amazon S3 bucket in an additional Region. How should this requirement be fulfilled? - Enable versioning for the source bucket and configure Cross-Region Replication An application is deployed in the us-west-1 and eu-west-1 Regions, and the users should be sent to the Region with the fastest response for them, regardless of their location. The solution must minimize administrative effort. Which routing policy should be used? - Latency A notification is sent to an Amazon SQS queue when an object is uploaded to an Amazon S3 bucket. An Amazon ECS cluster processes messages from the queue. The required queue size fluctuates based on the number of incoming messages and the processing speed. The company needs to design a scaling strategy for auto scaling that will minimize the queue size. Which metric should be used for auto scaling to minimize the queue size? - Amazon SQS messages A company hosts a website from two EC2 instances. Users access the website through an Elastic Load Balancer (ELB). The company needs to ensure the website is highly available if one or more of the EC2 instances are unavailable. Which solution should this company use? - Configure the ELB to implement Auto Scaling based on health checks A company plans to migrate a legacy application to EC2 with no modifications to the application. The company hopes to add modern cloud features to immediately respond to changing needs. Which cloud feature will achieve this goal? - Auto scaling A company plans to migrate a legacy application to EC2 with no modifications to the application. The application has regular seasonal increases in demand, and it must automatically adapt to these needs. Which scaling option should be included in the migration? - Scheduled
