Your application provides data transformation services. Files containing data to be transformed are first uploaded to Amazon S3 and then transformed by a fleet of spot EC2 instances. Files submitted by your premium customers must be transformed with the highest priority. How should you implement such a system?

• A.Use Route 53 latency based-routing to send high priority tasks to the closest transformation instances.
• B.Use a single SQS queue. Each message contains the priority level. Transformation instances poll high-priority messages first.
• C.Use a DynamoDB table with an attribute defining the priority level. Transformation instances will scan the table for tasks, sorting the results by priority level.
• D.Use two SQS queues, one for high priority messages, the other for default priority. Transformation instances first poll the high priority queue; if there is no message, they poll the default priority queue.

A solutions Architect is designing a web application that contains an Auto scaling group with AmazonEC2 instances behind an Elastic Load Balancing load balancer. The EC2 instances access static content within an AmazonS3 bucket. When application load reaches a specified threshold, the Auto scaling group will scale up and deploy new EC2 instances to handle the additional load.
When new EC2 instances are deployed using the Auto scaling group, what should the Architect do to ensure that the instances can access static content within the S3 bucket?

• A.Create a security group that grants AmazonS3 read-only permissions for instances behind the load balancer and apply it to the S3 bucket
• B.Configure the Auto scaling group to launch instances with an AWS IAM role with readonly permissions to the S3 bucket
• C.Create an AWS IAM user with a policy that grants the permissions to read the S3 bucket. Configure the load balancer to store the user's Public/Private key.
• D.Apply an AWS IAM policy to the S3 bucket that permits read-only access the folder 'staticcontent' from the EC2 instances
