A company hosts its order processing system on AWS. The architecture consists of a frontend and a backend.
The frontend includes an Application Load Balancer ALB and Amazon EC2 instances in an Auto Scaling group. The backend includes an EC2 instance and an Amazon RDS MySQL database.
To prevent incomplete or lost orders, the company wants to ensure that order states are always preserved. The company wants to ensure that every order will eventually be processed, even after an outage or pause. Every order must be processed exactly once.
Which solution will meet these requirements?

• A.Create an Auto Scaling group for the backend. Configure the backend EC2 instances to consume messages from an Amazon SQS FIFO queue. Configure a dead-letter queue DLQ for the SQS queue.
• B.Create an AWS Lambda function to replace the backend EC2 instance. Subscribe the function to an Amazon SNS topic. Configure the frontend to send orders to the SNS topic.
• C.Create an Auto Scaling group and an ALB for the backend. Create a read replica for the RDS database in a second Availability Zone. Update the backend RDS endpoint.
• D.Create an Auto Scaling group and an ALB for the backend. Create an Amazon RDS Proxy in front of the RDS database. Update the backend EC2 instance to use the Amazon RDS Proxy endpoint.

A company hosts an application on an Amazon EC2 instance in a single AWS Region. The application requires support for non-HTTP TCP traffic and HTTP traffic. The company wants to deliver content with low latency by using the AWS network. The company also wants to implement an Auto Scaling group with an Elastic Load Balancing (ELB) load balancer.
How should a solutions architect meet these requirements?

• A.Create an Auto Scaling group with an Application Load Balancer (ALB). Add an Amazon CloudFront distribution with the ALB as the origin.
• B.Create an Auto Scaling group with a Network Load Balancer (NLB). Add an accelerator with AWS Global Accelerator with the NLB as an endpoint.
• C.Create an Auto Scaling group with an Application Load Balancer (ALB). Add an accelerator with AWS Global Accelerator with the ALB as an endpoint.
• D.Create an Auto Scaling group with a Network Load Balancer (NLB). Add an Amazon CloudFront distribution with the NLB as the origin.

A company has a web application that has thousands of users. The application uses 8-10 user-uploaded images to generate Al images. Users can download the generated Al Images once every 6 hours. The company also has a premium user option that gives users the ability to download the generated Al images anytime The company uses the user-uploaded images to run Al model training twice a year. The company needs a storage solution to store the images.
Which storage solution meets these requirements MOST cost-effectively?

• A.Move uploaded images to Amazon S3 One Zone-Infrequent Access {S3 One Zone-IA) Move all generated Al images to S3 Glacier Flexible Retrieval
• B.Move uploaded images to Amazon S3 Glacier Deep Archive. Move all generated Al images to S3 Glacier Flexible Retrieval.
• C.Move uploaded images to Amazon S3 One Zone-Infrequent Access {S3 One Zone-IA) Move premium user-generated Al images to S3 Standard. Move non-premium user-generated Al images to S3 Standard- Infrequent Access (S3 Standard-IA).
• D.Move uploaded images to Amazon S3 Glacier Deep Archive. Move premium user-generated Al images to S3 Standard. Move non-premium user-generated Al images to S3 Standard-Infrequent Access (S3 Standard-IA).

A company wants to deploy an AWS Lambda function that will read and write objects to Amazon S3 bucket.
The Lambda function must be connected to the company ' s VPC. The company must deploy the Lambda function only to private subnets in the VPC. The Lambda function must not be allowed to access the internet.
Which solutions will meet these requirements? (Select TWO.)

• A.Create an interface VPC endpoint for the S3 bucket.
• B.Create a private NAT gateway to access the S3 bucket.
• C.Create a gateway VPC endpoint for the S3 bucket.
• D.Attach an Elastic IP address to the NAT gateway.
• E.Create a public NAT gateway to access the S3 bucket.

A solutions architect needs to design a solution for a high performance computing (HPC) workload. The solution must include multiple Amazon EC2 instances. Each EC2 instance requires 10 Gbps of bandwidth individually for single-flow traffic. The EC2 instances require an aggregate throughput of 100 Gbps of bandwidth across all EC2 instances. Communication between the EC2 instances must have low latency.
Which solution will meet these requirements?

• A.Place the EC2 instances in multiple subnets across multiple Availability Zones. Configure a cluster placement group. Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.
• B.Place the EC2 instances in multiple VPCs. Use AWS Transit Gateway to route traffic between the VPCs. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.
• C.Place the EC2 instances in multiple subnets in a single VPC. Configure a spread placement group.
  Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.
• D.Place the EC2 instances in a single subnet of a VPC. Configure a cluster placement group. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.
