A company has an application that runs on Amazon EC2 instances in an Amazon EC2 Auto Scaling group. The company uses AWS CodePipeline to deploy the application. The instances that run in the Auto Scaling group are constantly changing because of scaling events.
When the company deploys new application code versions, the company installs the AWS CodeDeploy agent on any new target EC2 instances and associates the instances with the CodeDeploy deployment group. The application is set to go live within the next 24 hours.
What should a solutions architect recommend to automate the application deployment process with the LEAST amount of operational overhead?

1. A. Configure Amazon EventBridge to invoke an AWS Lambda function when a new EC2 instance is launched into the Auto Scaling grou
2. B. Code the Lambda function to associate the EC2 instances with the CodeDeploy deployment group.
3. C. Write a script to suspend Amazon EC2 Auto Scaling operations before the deployment of new code When the deployment is complete, create a new AMI and configure the Auto Scaling group's launch template to use the new AMI for new launche
4. D. Resume Amazon EC2 Auto Scaling operations.
5. E. Create a new AWS CodeBuild project that creates a new AMI that contains the new code Configure CodeBuild to update the Auto Scaling group's launch template to the new AM
6. F. Run an Amazon EC2 Auto Scaling instance refresh operation.
7. G. Create a new AMI that has the CodeDeploy agent installe
8. H. Configure the Auto Scaling group's launch template to use the new AM
9. I. Associate the CodeDeploy deployment group with the Auto Scaling group instead of the EC2 instances.

A company is building an electronic document management system in which users upload their documents. The application stack is entirely serverless and runs on AWS in the eu-central-1 Region. The system includes a web application that uses an Amazon CloudFront distribution for delivery with Amazon S3 as the origin. The web application communicates with Amazon API Gateway Regional endpoints. The API Gateway APIs call AWS Lambda functions that store metadata in an Amazon Aurora Serverless database and put the documents into an S3 bucket.
The company is growing steadily and has completed a proof of concept with its largest customer. The company must improve latency outside of Europe.
Which combination of actions will meet these requirements? (Select TWO.)

1. A. Enable S3 Transfer Acceleration on the S3 bucke
2. B. Ensure that the web application uses the Transfer Acceleration signed URLs.
3. C. Create an accelerator in AWS Global Accelerato
4. D. Attach the accelerator to the CloudFront distribution.
5. E. Change the API Gateway Regional endpoints to edge-optimized endpoints.
6. F. Provision the entire stack in two other locations that are spread across the worl
7. G. Use global databases on the Aurora Serverless cluster.
8. H. Add an Amazon RDS proxy between the Lambda functions and the Aurora Serverless database.

A company is building a call center by using Amazon Connect. The company’s operations team is defining a disaster recovery (DR) strategy across AWS Regions. The contact center has dozens of contact flows, hundreds of users, and dozens of claimed phone numbers.
Which solution will provide DR with the LOWEST RTO?

1. A. Create an AWS Lambda function to check the availability of the Amazon Connect instance and to send a notification to the operations team in case of unavailabilit
2. B. Create an Amazon EventBridge rule to invoke the Lambda function every 5 minute
3. C. After notification, instruct the operations team to use theAWS Management Console to provision a new Amazon Connect instance in a second Regio
4. D. Deploy the contact flows, users, and claimed phone numbers by using an AWS CloudFormation template.
5. E. Provision a new Amazon Connect instance with all existing users in a second Regio
6. F. Create an AWS Lambda function to check the availability of the Amazon Connect instanc
7. G. Create an Amazon EventBridge rule to invoke the Lambda function every 5 minute
8. H. In the event of an issue, configure the Lambda function to deploy an AWS CloudFormation template that provisions contact flows and claimed numbers in the second Region.
9. I. Provision a new Amazon Connect instance with all existing contact flows and claimed phone numbers in a second Regio
10. J. Create an Amazon Route 53 health check for the URL of the Amazon Connect instanc
11. K. Create an Amazon CloudWatch alarm for failed health check
12. L. Create an AWS Lambda function to deploy an AWS CloudFormation template that provisions all user
13. M. Configure the alarm to invoke the Lambda function.
14. N. Provision a new Amazon Connect instance with all existing users and contact flows in a second Region.Create an Amazon Route 53 health check for the URL of the Amazon Connect instanc
15. O. Create an Amazon CloudWatch alarm for failed health check
16. P. Create an AWS Lambda function to deploy an AWS CloudFormation template that provisions claimed phone number
17. Q. Configure the alarm to invoke the Lambda function.

Correct Answer: D
Option D provisions a new Amazon Connect instance with all existing users and contact flows in a second Region. It also sets up an Amazon Route 53 health check for the URL of the Amazon Connect instance, an Amazon CloudWatch alarm for failed health checks, and an AWS Lambda function to deploy an AWS CloudFormation template that provisions claimed phone numbers. This option allows for the fastest recovery time because all the necessary components are already provisioned and ready to go in the second Region. In the event of a disaster, the failed health check will trigger the AWS Lambda function to deploy the CloudFormation template to provision the claimed phone numbers, which is the only missing component.

Correct Answer: C
it's the one that handles failover while B (the one shown as the answer today) it almost the same but does not handle failover.
