A solutions architect needs to advise a company on how to migrate its on-premises data processing application to the AWS Cloud. Currently, users upload input files through a web portal. The web server then stores the uploaded files on NAS and messages the processing server over a message queue. Each media file can take up to 1 hour to process. The company has determined that the number of media files awaiting processing is significantly higher during business hours, with the number of files rapidly declining after business hours.
What is the MOST cost-effective migration recommendation?

1. A. Create a queue using Amazon SQ
2. B. Configure the existing web server to publish to the new queue.When there are messages in the queue, invoke an AWS Lambda function to pull requests from the queue and process the file
3. C. Store the processed files in an Amazon S3 bucket.
4. D. Create a queue using Amazon
5. E. Configure the existing web server to publish to the new queu
6. F. When there are messages in the queue, create a new Amazon EC2 instance to pull requests from the queue and process the file
7. G. Store the processed files in Amazon EF
8. H. Shut down the EC2 instance after the task is complete.
9. I. Create a queue using Amazon M
10. J. Configure the existing web server to publish to the new queue.When there are messages in the queue, invoke an AWS Lambda function to pull requests from the queue and process the file
11. K. Store the processed files in Amazon EFS.
12. L. Create a queue using Amazon SO
13. M. Configure the existing web server to publish to the new queu
14. N. Use Amazon EC2 instances in an EC2 Auto Scaling group to pull requests from the queue and process the file
15. O. Scale the EC2 instances based on the SOS queue lengt
16. P. Store the processed files in an Amazon S3 bucket.

A company has an organization in AWS Organizations. The company is using AWS Control Tower to deploy a landing zone for the organization. The company wants to implement governance and policy enforcement. The company must implement a policy that will detect Amazon RDS DB instances that are not encrypted at rest in the company’s production OU.
Which solution will meet this requirement?

1. A. Turn on mandatory guardrails in AWS Control Towe
2. B. Apply the mandatory guardrails to the production OU.
3. C. Enable the appropriate guardrail from the list of strongly recommended guardrails in AWS Control Towe
4. D. Apply the guardrail to the production OU.
5. E. Use AWS Config to create a new mandatory guardrai
6. F. Apply the rule to all accounts in the production OU.
7. G. Create a custom SCP in AWS Control Towe
8. H. Apply the SCP to the production OU.

Correct Answer: B
AWS Control Tower provides a set of "strongly recommended guardrails" that can be enabled to implement governance and policy enforcement. One of these guardrails is "Encrypt Amazon RDS instances" which will
detect RDS DB instances that are not encrypted at rest. By enabling this guardrail and applying it to the production OU, the company will be able to enforce encryption for RDS instances in the production environment.

A company plans to refactor a monolithic application into a modern application designed deployed or AWS. The CLCD pipeline needs to be upgraded to support the modem design for the application with the following requirements
• It should allow changes to be released several times every hour.
* It should be able to roll back the changes as quickly as possible Which design will meet these requirements?

1. A. Deploy a Cl-CD pipeline that incorporates AMIs to contain the application and their configurationsDeploy the application by replacing Amazon EC2 instances
2. B. Specify AWS Elastic Beanstak to sage in a secondary environment as the deployment target for the CI/CD pipeline of the applicatio
3. C. To deploy swap the staging and production environment URLs.
4. D. Use AWS Systems Manager to re-provision the infrastructure for each deployment Update the Amazon EC2 user data to pull the latest code art-fact from Amazon S3 and use Amazon Route 53 weighted routing to point to the new environment
5. E. Roll out At application updates as pan of an Auto Scaling event using prebuilt AMI
6. F. Use new versions of the AMIs to add instances, and phase out all instances that use the previous AMI version with the configured termination policy during a deployment event.
