A company has an application that collects data from loT sensors on automobiles. The data is streamed and stored in Amazon S3 through Amazon Kinesis Date Firehose The data produces trillions of S3 objects each year. Each morning, the company uses the data from the previous 30 days to retrain a suite of machine learning (ML) models.
Four times each year, the company uses the data from the previous 12 months to perform analysis and train other ML models The data must be available with minimal delay for up to 1 year. After 1 year, the data must be retained for archival purposes.
Which storage solution meets these requirements MOST cost-effectively?

1. A. Use the S3 Intelligent-Tiering storage clas
2. B. Create an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 1 year
3. C. Use the S3 Intelligent-Tiering storage clas
4. D. Configure S3 Intelligent-Tiering to automatically move objects to S3 Glacier Deep Archive after 1 year.
5. E. Use the S3 Standard-Infrequent Access (S3 Standard-IA) storage clas
6. F. Create an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 1 year.
7. G. Use the S3 Standard storage clas
8. H. Create an S3 Lifecycle policy to transition objects to S3Standard-Infrequent Access (S3 Standard-IA) after 30 days, and then to S3 Glacier Deep Archive after 1 year.

Correct Answer: B

A gaming company has a web application that displays scores. The application runs on Amazon EC2 instances behind an Application Load Balancer. The application stores data in an Amazon RDS for MySQL database. Users are starting to experience long delays and interruptions that are caused by database read performance. The company wants to improve the user experience while minimizing changes to the application's architecture.
What should a solutions architect do to meet these requirements?

1. A. Use Amazon ElastiCache in front of the database.
2. B. Use RDS Proxy between the application and the database.
3. C. Migrate the application from EC2 instances to AWS Lambda.
4. D. Migrate the database from Amazon RDS for MySQL to Amazon DynamoDB.

Correct Answer: A
ElastiCache can help speed up the read performance of the database by caching frequently accessed data, reducing latency and allowing the application to access the data more quickly. This solution requires minimal modifications to the current architecture, as ElastiCache can be used in conjunction with the existing Amazon RDS for MySQL database.

A survey company has gathered data for several years from areas m the United States. The company hosts the data in an Amazon S3 bucket that is 3 TB m size and growing. The company has started to share the data with a European marketing firm that has S3 buckets The company wants to ensure that its data transfer costs remain as low as possible
Which solution will meet these requirements?

1. A. Configure the Requester Pays feature on the company's S3 bucket
2. B. Configure S3 Cross-Region Replication from the company’s S3 bucket to one of the marketing firm's S3 buckets.
3. C. Configure cross-account access for the marketing firm so that the marketing firm has access to the company’s S3 bucket.
4. D. Configure the company’s S3 bucket to use S3 Intelligent-Tiering Sync the S3 bucket to one of the marketing firm’s S3 buckets

Correct Answer: A
"Typically, you configure buckets to be Requester Pays buckets when you want to share data but not incur charges associated with others accessing the data. For example, you might use Requester Pays buckets when making available large datasets, such as zip code directories, reference data, geospatial information, or web crawling data." https://docs.aws.amazon.com/AmazonS3/latest/userguide/RequesterPaysBuckets.html
