A video processing company has an application that downloads images from an Amazon S3 bucket, processes the images, stores a transformed image in a second S3 bucket, and updates metadata about the image in an Amazon DynamoDB table. The application is written in Node.js and runs by using an AWS Lambda function. The Lambda function is invoked when a new image is uploaded to Amazon S3.
The application ran without incident for a while. However, the size of the images has grown significantly. The Lambda function is now failing frequently with timeout errors. The function timeout is set to its maximum value. A solutions architect needs to refactor the application’s architecture to prevent invocation failures. The company does not want to manage the underlying infrastructure.
Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)
- A . Modify the application deployment by building a Docker image that contains the application code.
Publish the image to Amazon Elastic Container Registry (Amazon ECR). - B . Create a new Amazon Elastic Container Service (Amazon ECS) task definition with a compatibility type of AWS Fargate. Configure the task definition to use the new image in Amazon Elastic Container Registry (Amazon ECR). Adjust the Lambda function to invoke an ECS task by using the ECS task definition when a new file arrives in Amazon S3.
- C . Create an AWS Step Functions state machine with a Parallel state to invoke the Lambda function.
Increase the provisioned concurrency of the Lambda function. - D . Create a new Amazon Elastic Container Service (Amazon ECS) task definition with a compatibility type of Amazon EC2. Configure the task definition to use the new image in Amazon Elastic Container Registry (Amazon ECR). Adjust the Lambda function to invoke an ECS task by using the ECS task definition when a new file arrives in Amazon S3.
- E . Modify the application to store images on Amazon Elastic File System (Amazon EFS) and to store metadata on an Amazon RDS DB instance. Adjust the Lambda function to mount the EFS file share.
A company has used infrastructure as code (IaC) to provision a set of two Amazon EC2 instances. The instances have remained the same for several years.
The company’s business has grown rapidly in the past few months. In response the company’s operations team has implemented an Auto Scaling group to manage the sudden increases in traffic. Company policy requires a monthly installation of security updates on all operating systems that are running.
The most recent security update required a reboot. As a result, the Auto Scaling group terminated the instances and replaced them with new, unpatched instances.
Which combination of steps should a solutions architect recommend to avoid a recurrence of this issue? (Choose two.)
- A . Modify the Auto Scaling group by setting the Update policy to target the oldest launch configuration for replacement.
- B . Create a new Auto Scaling group before the next patch maintenance. During the maintenance window, patch both groups and reboot the instances.
- C . Create an Elastic Load Balancer in front of the Auto Scaling group. Configure monitoring to ensure that target group health checks return healthy after the Auto Scaling group replaces the terminated instances.
- D . Create automation scripts to patch an AMI, update the launch configuration, and invoke an Auto Scaling instance refresh.
- E . Create an Elastic Load Balancer in front of the Auto Scaling group. Configure termination protection on the instances.
A multinational media company is building a video processing platform on AWS. The platform is deployed across multiple AWS accounts in an organization in AWS Organizations. Customers upload videos through Amazon API Gateway. AWS Lambda functions process the videos. The company stores processed media and metadata in Amazon S3 and Amazon DynamoDB. The company serves customers globally.
Regulatory requirements state that the company must process and store European Union (EU)
