A company has migrated its forms-processing application to AWS. When users interact with the application, they upload scanned forms as files through a web application. A database stores user metadata and references to files that are stored in Amazon S3. The web application runs on Amazon EC2 instances and an Amazon RDS for PostgreSQL database.
When forms are uploaded, the application sends notifications to a team through Amazon Simple Notification Service (Amazon SNS). A team member then logs in and processes each form. The team member performs data validation on the form and extracts relevant data before entering the information into another system that uses an API.
A solutions architect needs to automate the manual processing of the forms. The solution must provide accurate form extraction, minimize time to market, and minimize long-term operational overhead.
Which solution will meet these requirements?

1. A. Develop custom libraries to perform optical character recognition (OCR) on the form
2. B. Deploy the libraries to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster as an application tie
3. C. Use this tier to process the forms when forms are uploade
4. D. Store the output in Amazon S3. Parse this output by extracting the data into an Amazon DynamoDB tabl
5. E. Submit the data to the target system's AP
6. F. Host the new application tier on EC2 instances.
7. G. Extend the system with an application tier that uses AWS Step Functions and AWS Lambd
8. H. Configure this tier to use artificial intelligence and machine learning (AI/ML) models that are trained and hosted on an EC2 instance to perform optical character recognition (OCR) on the forms when forms are uploade
9. I. Store the output in Amazon S3. Parse this output by extracting the data that is required within the application tie
10. J. Submit the data to the target system's API.
11. K. Host a new application tier on EC2 instance
12. L. Use this tier to call endpoints that host artificial intelligence and machine learning (Al/ML) models that are trained and hosted in Amazon SageMaker to perform optical character recognition (OCR) on the form
13. M. Store the output in Amazon ElastiCach
14. N. Parse this output by extracting the data that is required within the application tie
15. O. Submit the data to the target system's API.
16. P. Extend the system with an application tier that uses AWS Step Functions and AWS Lambd
17. Q. Configure this tier to use Amazon Textract and Amazon Comprehend to perform optical character recognition (OCR) on the forms when forms are uploade
18. R. Store the output in Amazon S3. Parse this output by extracting the data that is required within the application tie
19. S. Submit the data to the target system's API.

A large company is running a popular web application. The application runs on several Amazon EC2 Linux Instances in an Auto Scaling group in a private subnet. An Application Load Balancer is targeting the Instances In the Auto Scaling group in the private subnet. AWS Systems Manager Session Manager Is configured, and AWS Systems Manager Agent is running on all the EC2 instances.
The company recently released a new version of the application Some EC2 instances are now being marked as unhealthy and are being terminated As a result, the application is running at reduced capacity A solutions architect tries to determine the root cause by analyzing Amazon CloudWatch logs that are collected from the application, but the logs are inconclusive
How should the solutions architect gain access to an EC2 instance to troubleshoot the issue1?

1. A. Suspend the Auto Scaling group's HealthCheck scaling proces
2. B. Use Session Manager to log in to an instance that is marked as unhealthy
3. C. Enable EC2 instance termination protection Use Session Manager to log In to an instance that is marked as unhealthy.
4. D. Set the termination policy to Oldestinstance on the Auto Scaling grou
5. E. Use Session Manager to log in to an instance that is marked as unhealthy
6. F. Suspend the Auto Scaling group's Terminate proces
7. G. Use Session Manager to log in to an instance that is marked as unhealthy

Correct Answer: D
https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-suspend-resume-processes.html
it shows For Amazon EC2 Auto Scaling, there are two primary process types: Launch and Terminate. The Launch process adds a new Amazon EC2 instance to an Auto Scaling group, increasing its capacity. The
Terminate process removes an Amazon EC2 instance from the group, decreasing its capacity. HealthCheck process for EC2 autoscaling is not a primary process! It is a process along with the following AddToLoadBalancer AlarmNotification AZRebalance HealthCheck InstanceRefresh ReplaceUnhealthy ScheduledActions From the requirements, Some EC2 instances are now being marked as unhealthy and are being terminated. Application is running at reduced capacity not because instances are marked unhealthy but because they are being terminated.

An international delivery company hosts a delivery management system on AWS. Drivers use the system to upload confirmation of delivery. Confirmation includes the recipient's signature or a photo of the package with the recipient. The driver's handheld device uploads signatures and photos through FTP to a single Amazon EC2 instance. Each handheld device saves a file in a directory based on the signed-in user, and the file name matches the delivery number. The EC2 instance then adds metadata to the file after querying a central database to pull delivery information. The file is then placed in Amazon S3 for archiving.
As the company expands, drivers report that the system is rejecting connections. The FTP server is having problems because of dropped connections and memory issues. In response to these problems, a system engineer schedules a cron task to reboot the EC2 instance every 30 minutes. The billing team reports that files are not always in the archive and that the central system is not always updated.
A solutions architect needs to design a solution that maximizes scalability to ensure that the archive always receives the files and that systems are always updated. The handheld devices cannot be modified, so the company cannot deploy a new application.
Which solution will meet these requirements?

1. A. Create an AMI of the existing EC2 instanc
2. B. Create an Auto Scaling group of EC2 instances behind an Application Load Balance
3. C. Configure the Auto Scaling group to have a minimum of three instances.
4. D. Use AWS Transfer Family to create an FTP server that places the files in Amazon Elastic File System (Amazon EFS). Mount the EFS volume to the existing EC2 instanc
5. E. Point the EC2 instance to the new path for file processing.
6. F. Use AWS Transfer Family to create an FTP server that places the files in Amazon S3. Use an S3 event notification through Amazon Simple Notification Service (Amazon SNS) to invoke an AWS Lambda functio
7. G. Configure the Lambda function to add the metadata and update the delivery system.
8. H. Update the handheld devices to place the files directly in Amazon S3. Use an S3 event notification through Amazon Simple Queue Service (Amazon SQS) to invoke an AWS Lambda functio
9. I. Configure the Lambda function to add the metadata and update the delivery system.
