A university is running computational algorithms that require large amounts of compute power. The algorithms are being run using a high-performance compute cluster on Amazon EC2 Spot instances. Each time an instance launches a DNS record must be created in an Amazon Route 53 private hosted zone. When the instance is terminated the DNS record must be deleted. The current configuration uses an Amazon CloudWatch Events rule that triggers an AWS Lambda function to create the DNS record. When scaling the solution to thousands of instances the university has experienced “HTTP 400 error (Bad request)” errors in the Lambda logs. The response header also includes a status code element with a value of "Throttling" and a status message element with a value of "Rate exceeded". Which combination of steps should the Solutions Architect take to resolve these issues? (Select THREE.)
