A company is migrating its on-premises workload to the AWS Cloud. The company already uses several Amazon EC2 instances and Amazon RDS DB instances. The company wants a solution that automatically starts and stops the EC2 instances and D6 instances outside of business hours. The solution must minimize cost and infrastructure maintenance.
Which solution will meet these requirement?

1. A. Scale the EC2 instances by using elastic resize Scale the DB instances to zero outside of business hours
2. B. Explore AWS Marketplace for partner solutions that will automatically start and stop the EC2 Instances and OB instances on a schedule
3. C. Launch another EC2 instanc
4. D. Configure a crontab schedule to run shell scripts that will start and stop the existing EC2 instances and DB instances on a schedule.
5. E. Create an AWS Lambda function that will start and stop the EC2 instances and DB instances Configure Amazon EventBridge to invoke the Lambda function on a schedule

Correct Answer: D

An image-processing company has a web application that users use to upload images. The application uploads the images into an Amazon S3 bucket. The company has set up S3 event notifications to publish the object creation events to an Amazon Simple Queue Service (Amazon SQS) standard queue. The SQS queue serves as the event source for an AWS Lambda function that processes the images and sends the results to users through email.
Users report that they are receiving multiple email messages for every uploaded image. A solutions architect determines that SQS messages are invoking the Lambda function more than once, resulting in multiple email messages.
What should the solutions architect do to resolve this issue with the LEAST operational overhead?

1. A. Set up long polling in the SQS queue by increasing the ReceiveMessage wait time to 30 seconds.
2. B. Change the SQS standard queue to an SQS FIFO queu
3. C. Use the message deduplication ID to discard duplicate messages.
4. D. Increase the visibility timeout in the SQS queue to a value that is greater than the total of the function timeout and the batch window timeout.
5. E. Modify the Lambda function to delete each message from the SQS queue immediately after the message is read before processing.

Correct Answer: C

A company runs an application on Amazon EC2 Linux instances across multiple Availability Zones. The application needs a storage layer that is highly available and Portable Operating System Interface (POSIX) compliant. The storage layer must provide maximum data durability and must be shareable across the EC2 instances. The data in the storage layer will be accessed frequency for the first 30 days and will be accessed infrequently alter that time.
Which solution will meet these requirements MOST cost-effectively?

1. A. Use the Amazon S3 Standard storage class Create an S3 Lifecycle policy to move infrequently accessed data to S3 Glacier
2. B. Use the Amazon S3 Standard storage clas
3. C. Create an S3 Lifecycle policy to move infrequently accessed data to S3 Standard-Infrequent Access (EF3 Standard-IA).
4. D. Use the Amazon Elastic File System (Amazon EFS) Standard storage clas
5. E. Create a Lifecycle management policy to move infrequently accessed data to EFS Standard-Infrequent Access (EFS Standard-IA)
6. F. Use the Amazon Elastic File System (Amazon EFS) One Zone storage clas
7. G. Create a Lifecycle management policy to move infrequently accessed data to EFS One Zone-Infrequent Access (EFS One Zone-IA).

Correct Answer: C

A company has deployed a Java Spring Boot application as a pod that runs on Amazon Elastic Kubernetes Service (Amazon EKS) in private subnets. The application needs to write data to an Amazon DynamoDB table. A solutions architect must ensure that the application can interact with the DynamoDB table without exposing traffic to the internet.
Which combination of steps should the solutions architect take to accomplish this goal? (Choose two.)

1. A. Attach an IAM role that has sufficient privileges to the EKS pod.
2. B. Attach an IAM user that has sufficient privileges to the EKS pod.
3. C. Allow outbound connectivity to the DynamoDB table through the private subnets’ network ACLs.
4. D. Create a VPC endpoint for DynamoDB.
5. E. Embed the access keys in the Java Spring Boot code.

A company runs a high performance computing (HPC) workload on AWS. The workload required low-latency network performance and high network throughput with tightly coupled node-to-node communication. The Amazon EC2 instances are properly sized for compute and storage capacity, and are launched using default options.
What should a solutions architect propose to improve the performance of the workload?

1. A. Choose a cluster placement group while launching Amazon EC2 instances.
2. B. Choose dedicated instance tenancy while launching Amazon EC2 instances.
3. C. Choose an Elastic Inference accelerator while launching Amazon EC2 instances.
4. D. Choose the required capacity reservation while launching Amazon EC2 instances.

Correct Answer: A
