4996. A large company is migrating its entire IT portfolio to AWS. Each business unit in the company has a standalone AWS account that supports both development and test environments. New accounts to support production workloads will be needed soon.
The Finance department requires a centralized method for payment but must maintain visibility into each group's spending to allocate costs.
The Security team requires a centralized mechanism to control IAM usage in all the company's accounts.
What combination of the following options meet the company's needs with LEAST effort? (Choose two.)- Aa. Use a collection of parameterized AWS CloudFormation templates defining common IAM permissions that are launched into each account. Require all new and existing accounts to launch the appropriate stacks to enforce the least privilege model.
- Bb. Use AWS Organizations to create a new organization from a chosen payer account and define an organizational unit hierarchy. Invite the existing accounts to join the organization and create new accounts using Organizations.
- Cc. Require each business unit to use its own AWS accounts. Tag each AWS account appropriately and enable Cost Explorer to administer chargebacks.
- Dd. Enable all features of AWS Organizations and establish appropriate service control policies that filter IAM permissions for sub-accounts.
- Ee. Consolidate all of the company's AWS accounts into a single AWS account. Use tags for billing purposes and IAM's Access Advice feature to enforce the least privilege model.

5197. A company collects a steady stream of 10 million data records from 100,000 sources each day. These records are written to an Amazon RDS MySQL DB. A query must produce the daily average of a data source over the past 30 days. There are twice as many reads as writes. Queries to the collected data are for one source ID at a time.
How can the Solutions Architect improve the reliability and cost effectiveness of this solution?- Aa. Use Amazon Aurora with MySQL in a Multi-AZ mode. Use four additional read replicas.
- Bb. Use Amazon DynamoDB with the source ID as the partition key and the timestamp as the sort key. Use a Time to Live (TTL) to delete data after 30 days.
- Cc. Use Amazon DynamoDB with the source ID as the partition key. Use a different table each day.
- Dd. Ingest data into Amazon Kinesis using a retention period of 30 days. Use AWS Lambda to write data records to Amazon ElastiCache for read access.
