A company has an automobile sales website that stores its listings in a database on Amazon RDS When an automobile is sold the listing needs to be removed from the website and the data must be sent to multiple target systems.
Which design should a solutions architect recommend?

1. A. Create an AWS Lambda function triggered when the database on Amazon RDS is updated to send the information to an Amazon Simple Queue Service (Amazon SQS> queue for the targets to consume
2. B. Create an AWS Lambda function triggered when the database on Amazon RDS is updated to send the information to an Amazon Simple Queue Service (Amazon SQS) FIFO queue for the targets to consume
3. C. Subscribe to an RDS event notification and send an Amazon Simple Queue Service (Amazon SQS) queue fanned out to multiple Amazon Simple Notification Service (Amazon SNS) topics Use AWS Lambda functions to update the targets
4. D. Subscribe to an RDS event notification and send an Amazon Simple Notification Service (Amazon SNS) topic fanned out to multiple Amazon Simple Queue Service (Amazon SQS) queues Use AWS Lambda functions to update the targets

A company has an Amazon S3 bucket that contains critical data. The company must protect the data from accidental deletion.
Which combination of steps should a solutions architect take to meet these requirements?
(Choose two.)

1. A. Enable versioning on the S3 bucket.
2. B. Enable MFA Delete on the S3 bucket.
3. C. Create a bucket policy on the S3 bucket.
4. D. Enable default encryption on the S3 bucket.
5. E. Create a lifecycle policy for the objects in the S3 bucket.

Correct Answer: AB
To protect data in an S3 bucket from accidental deletion, versioning should be enabled, which enables you to preserve, retrieve, and restore every version of every object in an S3 bucket. Additionally, enabling MFA (multi-factor authentication) Delete on the S3 bucket adds an extra layer of protection by requiring an authentication token in addition to the user's access keys to delete objects in the bucket.

A company wants to run its experimental workloads in the AWS Cloud. The company has a budget for cloud spending. The company's CFO is concerned about cloud spending accountability for each department. The CFO wants to receive notification when the spending threshold reaches 60% of the budget.
Which solution will meet these requirements?

1. A. Use cost allocation tags on AWS resources to label owner
2. B. Create usage budgets in AWS Budget
3. C. Add an alert threshold to receive notification when spending exceeds 60% of the budget.
4. D. Use AWS Cost Explorer forecasts to determine resource owner
5. E. Use AWS Cost Anomaly Detection to create alert threshold notifications when spending exceeds 60% of the budget.
6. F. Use cost allocation tags on AWS resources to label owner
7. G. Use AWS Support API on AWS Trusted Advisor to create alert threshold notifications when spending exceeds 60% of the budget
8. H. Use AWS Cost Explorer forecasts to determine resource owner
9. I. Create usage budgets in AWS Budget
10. J. Add an alert threshold to receive notification when spending exceeds 60% of the budget.

Correct Answer: A
This solution meets the requirements because it allows the company to track and manage its cloud spending by using cost allocation tags to assign costs to different departments, creating usage budgets to set spending limits, and adding alert thresholds to receive notifications when the spending reaches a certain percentage of the budget. This way, the company can monitor its experimental workloads and avoid overspending on the cloud.

A company is planning to store data on Amazon RDS DB instances. The company must encrypt the data at rest.
What should a solutions architect do to meet this requirement?

1. A. Create an encryption key and store the key in AWS Secrets Manager Use the key to encrypt the DB instances
2. B. Generate a certificate in AWS Certificate Manager (ACM). Enable SSL/TLS on the DB instances by using the certificate
3. C. Create a customer master key (CMK) in AWS Key Management Service (AWS KMS) Enable encryption for the DB instances
4. D. Generate a certificate in AWS Identity and Access Management {IAM) Enable SSUTLS on the DB instances by using the certificate

Correct Answer: A
To encrypt data at rest in Amazon RDS, you can use the encryption feature of Amazon RDS, which uses AWS Key Management Service (AWS KMS). With this feature, Amazon RDS encrypts each database instance with a unique key. This key is stored securely by AWS KMS. You can manage your own keys or use the default AWS-managed keys. When you enable encryption for a DB instance, Amazon RDS encrypts the underlying storage, including the automated backups, read replicas, and snapshots.
