A company has an application that sells tickets online and experiences bursts of demand every 7 days. The application has a stateless presentation layer running on Amazon EC2. an Oracle database to store unstructured data catalog information, and a backend API layer. The front-end layer uses an Elastic Load Balancer to distribute the load across nine On-Demand Instances over three Availability Zones (AZs). The Oracle database is running on a single EC2 instance. The company is experiencing performance issues when running more than two concurrent campaigns. A solutions architect must design a solution that meets the following requirements:
• Address scalability issues.
• Increase the level of concurrency.
• Eliminate licensing costs.
• Improve reliability.
Which set of steps should the solutions architect take?

1. A. Create an Auto Scaling group for the front end with a combination of On-Demand and Spot Instances to reduce cost
2. B. Convert the Oracle database into a single Amazon RDS reserved DB instance.
3. C. Create an Auto Scaling group for the front end with a combination of On-Demand and Spot Instances to reduce cost
4. D. Create two additional copies of the database instance, then distribute the databases in separate AZs.
5. E. Create an Auto Scaling group for the front end with a combination of On-Demand and Spot Instances to reduce cost
6. F. Convert the tables in the Oracle database into Amazon DynamoDB tables.
7. G. Convert the On-Demand Instances into Spot Instances to reduce costs for the front en
8. H. Convert the tables in the Oracle database into Amazon DynamoDB tables.

Correct Answer: C
Combination of On-Demand and Spot Instances + DynamoDB.

A company is planning to migrate an application from on premises to AWS. The application currently uses an Oracle database and the company can tolerate a brief downtime of 1 hour when performing the switch to the new infrastructure As part of the migration. the database engine will be changed to MySQL. A solutions architect needs to determine which AWS services can be used to perform the migration while minimizing the amount of work and time required.
Which of the following will meet the requirements?

1. A. Use AWS SCT to generate the schema scripts and apply them on the target prior to migration Use AWS DMS to analyse the current schema and provide a recommendation for the optimal database engine Then, use AWS DMS to migrate to the recommended engine Use AWS SCT to identify what embedded SQL code in the application can be converted and what has to be done manually
2. B. Use AWS SCT to generate the schema scripts and apply them on the target prior to migratio
3. C. Use AWS DMS to begin moving data from the on-premises database to AW
4. D. After the initial copy continue to use AWS DMS to keep the databases m sync until cutting over to the new database Use AWS SCT to identify what embedded SOL code in the application can be converted and what has to be done manually.
5. E. Use AWS DMS lo help identify the best target deployment between installing the database engine on Amazon EC2 directly or moving to Amazon RD
6. F. Then, use AWS DMS to migrate to the platfor
7. G. Use AWS Application Discovery Service to identify what embedded SQL code in the application can be converted and what has to be done manually.
8. H. Use AWS DMS to begin moving data from the on-premises database to AWS After the initial copy, continue to use AWS DMS to keep the databases in sync until cutting over to the new database use AWS Application Discovery Service to identify what embedded SQL code m the application can be convened and what has to be done manually

Correct Answer: B

A software company has deployed an application that consumes a REST API by using Amazon API Gateway. AWS Lambda functions, and an Amazon DynamoDB table. The application is showing an increase in the number of errors during PUT requests. Most of the PUT calls come from a small number of clients that are authenticated with specific API keys.
A solutions architect has identified that a large number of the PUT requests originate from one client. The API is noncritical, and clients can tolerate retries of unsuccessful calls. However, the errors are displayed to customers and are causing damage to the API's reputation.
What should the solutions architect recommend to improve the customer experience?

1. A. Implement retry logic with exponential backoff and irregular variation in the client applicatio
2. B. Ensure that the errors are caught and handled with descriptive error messages.
3. C. Implement API throttling through a usage plan at the API Gateway leve
4. D. Ensure that the client application handles code 429 replies without error.
5. E. Turn on API caching to enhance responsiveness for the production stag
6. F. Run 10-minute load tests.Verify that the cache capacity is appropriate for the workload.
7. G. Implement reserved concurrency at the Lambda function level to provide the resources that are needed during sudden increases in traffic.

Correct Answer: A

The company needs to determine which costs on the monthly AWS bill are attributable to each application or team. The company also must be able to create reports to compare costs from the last 12 months and to help forecast costs for the next 12 months. A solutions architect must recommend an AWS Billing and Cost Management solution that provides these cost reports.
Which combination of actions will meet these requirements? (Select THREE.)

1. A. Activate the user-defined cost allocation tags that represent the application and the team.
2. B. Activate the AWS generated cost allocation tags that represent the application and the team.
3. C. Create a cost category for each application in Billing and Cost Management.
4. D. Activate IAM access to Billing and Cost Management.
5. E. Create a cost budget.
6. F. Enable Cost Explorer.

What should the solutions architect do to meet this requirement7

1. A. / Use Amazon CloudWatch to monitor the Sample Count statistic for each service in the ECS cluster Se: an alarm for when the math expression sample Notification SERVICE_QUOTA(service)"100 is greater than 80 Notify the development team by using Amazon Simple Notification Service (Amazon SNS)
2. B. Use Amazon CloudWatch to monitor service quotas that are published under the AWS-'Usage metric namespace Set an alarm for when the math expression metricSERVlCE QUOTA(metric)"100 is greater than 80 Notify the development team by using Amazon Simple Notification Service (Amazon SNS).
3. C. Create an AWS Lambda function to poll detailed metrics from the ECS cluste
4. D. When the number running Fargate tasks is greater than 80. invoke Amazon Simple Email Service (Amazon SES) to notify the development team
5. E. Create an AWS Config rule to evaluate whether the Fargate SERVICE_QUOTA is greater than 80. UseAmazon Simple Email Service (Amazon SES) to notify the development team when the AWS Config rule is not compliant.

Correct Answer: B
