A company is running applications on AWS in a multi-account environment. The company's sales team and marketing team use separate AWS accounts in AWS Organizations.
The sales team stores petabytes of data in an Amazon S3 bucket. The marketing team uses Amazon QuickSight for data visualizations. The marketing team needs access to data that the sates team stores in the S3 bucket. The company has encrypted the S3 bucket with an AWS Key Management Service (AWS KMS) key. The marketing team has already created the IAM service role for QuickSight to provide QuickSight access in the marketing AWS account. The company needs a solution that will provide secure access to the data in the S3 bucket across AWS accounts.
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Create a new S3 bucket in the marketing accoun
2. B. Create an S3 replication rule in the sales account to copy the objects to the new S3 bucket in the marketing accoun
3. C. Update the QuickSight permissions in the marketing account to grant access to the new S3 bucket.
4. D. Create an SCP to grant access to the S3 bucket to the marketing accoun
5. E. Use AWS Resource Access Manager (AWS RAM) to share the KMS key from the sates account with the marketing accoun
6. F. Update the QuickSight permissions in the marketing account to grant access to the S3 bucket.
7. G. Update the S3 bucket policy in the marketing account to grant access to the QuickSight rol
8. H. Create a KMS grant for the encryption key that is used in the S3 bucke
9. I. Grant decrypt access to the QuickSight rol
10. J. Update the QuickSight permissions in the marketing account to grant access to the S3 bucket.
11. K. Create an 1AM role in the sales account and grant access to the S3 bucke
12. L. From the marketing account,assume the 1AM role in the sales account to access the S3 bucke
13. M. Update the QuickSight rote, to create a trust relationship with the new 1AM role in the sales account.

Which actions should the solutions architect take to resolve this issue? (Select THREE.)

1. A. Reshard the stream to increase the number of shards in the stream.
2. B. Use the Kinesis Producer Library (KPL). Adjust the polling frequency.
3. C. Use consumers with the enhanced fan-out feature.
4. D. Reshard the stream to reduce the number of shards in the stream.
5. E. Use an error retry and exponential backoff mechanism in the consumer logic.
6. F. Configure the stream to use dynamic partitioning.
