A retail company runs a business-critical web service on an Amazon Elastic Container Service (Amazon ECS) cluster that runs on Amazon EC2 instances The web service receives POST requests from end users and writes data to a MySQL database that runs on a separate EC2 instance The company needs to ensure that data loss does not occur.
The current code deployment process includes manual updates of the ECS service During a recent deployment, end users encountered intermittent 502 Bad Gateway errors in response to valid web requests
The company wants to implement a reliable solution to prevent this issue from recurring. The company also wants to automate code deployments. The solution must be highly available and must optimize
cost-effectiveness
Which combination of steps will meet these requirements? (Select THREE.)

1. A. Run the web service on an ECS cluster that has a Fargate launch type Use AWS CodePipeline and AWS CodeDeploy to perform a blue/green deployment with validation testing to update the ECS service.
2. B. Migrate the MySQL database to run on an Amazon RDS for MySQL Multi-AZ DB instance that usesProvisioned IOPS SSD (io2) storage
3. C. Configure an Amazon Simple Queue Service (Amazon SQS) queue as an event source to receive the POST requests from the web service Configure an AWS Lambda function to poll the queue Write the data to the database.
4. D. Run the web service on an ECS cluster that has a Fargate launch type Use AWS CodePipeline and AWS CodeDeploy to perform a canary deployment to update the ECS service.

Correct Answer: CD

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 has migrated an application from on premises to AWS. The application frontend is a static website that runs on two Amazon EC2 instances behind an Application Load Balancer (ALB). The application backend is a Python application that runs on three EC2 instances behind another ALB. The EC2 instances are large, general purpose On-Demand Instances that were sized to meet the on-premises specifications for peak usage of the application.
The application averages hundreds of thousands of requests each month. However, the application is used mainly during lunchtime and receives minimal traffic during the rest of the day.
A solutions architect needs to optimize the infrastructure cost of the application without negatively affecting the application availability.
Which combination of steps will meet these requirements? (Choose two.)

1. A. Change all the EC2 instances to compute optimized instances that have the same number of cores as the existing EC2 instances.
2. B. Move the application frontend to a static website that is hosted on Amazon S3.
3. C. Deploy the application frontend by using AWS Elastic Beanstal
4. D. Use the same instance type for the nodes.
5. E. Change all the backend EC2 instances to Spot Instances.
6. F. Deploy the backend Python application to general purpose burstable EC2 instances that have the same number of cores as the existing EC2 instances.

Correct Answer: BE

A company developed a pilot application by using AWS Elastic Beanstalk and Java. To save costs during development, the company's development team deployed the application into a single-instance environment. Recent tests indicate that the application consumes more CPU than expected. CPU utilization is regularly greater than 85%, which causes some performance bottlenecks.
A solutions architect must mitigate the performance issues before the company launches the application to production.
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Create a new Elastic Beanstalk applicatio
2. B. Select a load-balanced environment typ
3. C. Select all Availability Zone
4. D. Add a scale-out rule that will run if the maximum CPU utilization is over 85% for 5 minutes.
5. E. Create a second Elastic Beanstalk environmen
6. F. Apply the traffic-splitting deployment polic
7. G. Specify a percentage of incoming traffic to direct to the new environment in the average CPU utilization is over 85% for 5 minutes.
8. H. Modify the existing environment's capacity configuration to use a load-balanced environment type.Select all Availability Zone
9. I. Add a scale-out rule that will run if the average CPU utilization is over 85% for 5 minutes.
10. J. Select the Rebuild environment action with the load balancing option Select an Availability Zones Add a scale-out rule that will run if the sum CPU utilization is over 85% for 5 minutes.

A company that uses AWS Organizations allows developers to experiment on AWS. As part of the landing zone that the company has deployed, developers use their company email address to request an account. The company wants to ensure that developers are not launching costly services or running services unnecessarily. The company must give developers a fixed monthly budget to limit their AWS costs.
Which combination of steps will meet these requirements? (Choose three.)

1. A. Create an SCP to set a fixed monthly account usage limi
2. B. Apply the SCP to the developer accounts.
3. C. Use AWS Budgets to create a fixed monthly budget for each developer's account as part of the account creation process.
4. D. Create an SCP to deny access to costly services and component
5. E. Apply the SCP to the developer accounts.
6. F. Create an IAM policy to deny access to costly services and component
7. G. Apply the IAM policy to the developer accounts.
8. H. Create an AWS Budgets alert action to terminate services when the budgeted amount is reached.Configure the action to terminate all services.
9. I. Create an AWS Budgets alert action to send an Amazon Simple Notification Service (Amazon SNS) notification when the budgeted amount is reache
10. J. Invoke an AWS Lambda function to terminate all services.
