A company is planning to migrate an Amazon RDS for Oracle database to an RDS for PostgreSQL DB instance in another AWS account A solutions architect needs to design a migration strategy that will require no downtime and that will minimize the amount of time necessary to complete the migration The migration strategy must replicate all existing data and any new data that is created during the migration The target database must be identical to the source database at completion of the migration process
All applications currently use an Amazon Route 53 CNAME record as their endpoint for communication with the RDS for Oracle DB instance The RDS for Oracle DB instance is in a private subnet
Which combination of steps should the solutions architect take to meet these requirements? (Select THREE )

1. A. Create a new RDS for PostgreSQL DB instance in the target account Use the AWS Schema Conversion Tool (AWS SCT) to migrate the database schema from the source database to the target database.
2. B. Use the AWS Schema Conversion Tool (AWS SCT) to create a new RDS for PostgreSQL DB instance in the target account with the schema and initial data from the source database
3. C. Configure VPC peering between the VPCs in the two AWS accounts to provide connectivity to both DB instances from the target accoun
4. D. Configure the security groups that are attached to each DB instance to allow traffic on the database port from the VPC in the target account
5. E. Temporarily allow the source DB instance to be publicly accessible to provide connectivity from the VPC in the target account Configure the security groups that are attached to each DB instance to allow traffic on the database port from the VPC in the target account.
6. F. Use AWS Database Migration Service (AWS DMS) in the target account to perform a full load plus change data capture (CDC) migration from the source database to the target database When the migration is complete, change the CNAME record to point to the target DB instance endpoint
7. G. Use AWS Database Migration Service (AWS DMS) in the target account to perform a change data capture (CDC) migration from the source database to the target database When the migration is complete change the CNAME record to point to the target DB instance endpoint

A company has implemented an ordering system using an event-dnven architecture. Dunng initial testing, the system stopped processing orders Further tog analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SOS) standard queue was causing an error on the backend and blocking all subsequent order messages The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds. A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages
Which step should the solutions architect take to meet these requirements?

1. A. Increase the backend processing timeout to 30 seconds to match the visibility timeout
2. B. Reduce the visibility timeout of the queue to automatically remove the faulty message
3. C. Configure a new SOS FIFO queue as a dead-letter queue to isolate the faulty messages
4. D. Configure a new SOS standard queue as a dead-letter queue to isolate the faulty messages.

A solutions architect is designing an application to accept timesheet entries from employees on their mobile devices. Timesheets will be submitted weekly, with most of the submissions occurring on Friday. The data must be stored in a format that allows payroll administrators to run monthly reports. The infrastructure must be highly available and scale to match the rate of incoming data and reporting requests.
Which combination of steps meets these requirements while minimizing operational overhead? (Select TWO.)

1. A. Deploy the application to Amazon EC2 On-Demand Instances With load balancing across multiple Availability Zone
2. B. Use scheduled Amazon EC2 Auto Scaling to add capacity before the high volume of submissions on Fridays.
3. C. Deploy the application in a container using Amazon Elastic Container Service (Amazon ECS) with load balancing across multiple Availability Zone
4. D. Use scheduled Service Auto Scaling to add capacity before the high volume of submissions on Fridays.
5. E. Deploy the application front end to an Amazon S3 bucket served by Amazon CloudFron
6. F. Deploy the application backend using Amazon API Gateway with an AWS Lambda proxy integration.
7. G. Store the timesheet submission data in Amazon Redshif
8. H. Use Amazon OuickSight to generate the reports using Amazon Redshift as the data source.
9. I. Store the timesheet submission data in Amazon S3. Use Amazon Athena and Amazon OuickSight to generate the reports using Amazon S3 as the data source.

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 company is planning to store a large number of archived documents and make the documents available to employees through the corporate intranet. Employees will access the system by connecting through a client VPN service that is attached to a VPC. The data must not be accessible to the public.
The documents that the company is storing are copies of data that is held on physical media elsewhere. The number of requests will be low. Availability and speed of retrieval are not concerns of the company.
Which solution will meet these requirements at the LOWEST cost?

8. H. Launch an Amazon EC2 instance that runs a web server Attach an Amazon Elastic Block Store (Amazon EBS) volume to store the archived dat
9. I. Use the Cold HDD (sc1) volume typ
10. J. Configure the instance security groups to allow access only from private networks.
11. K. Create an Amazon S3 bucke
