A company has its cloud infrastructure on AWS A solutions architect needs to define the infrastructure as code. The infrastructure is currently deployed in one AWS Region. The company's business expansion plan includes deployments in multiple Regions across multiple AWS accounts
What should the solutions architect do to meet these requirements?

1. A. Use AWS CloudFormation templates Add IAM policies to control the various accounts Deploy the templates across the multiple Regions
2. B. Use AWS Organizations Deploy AWS CloudFormation templates from the management account Use AWS Control Tower to manage deployments across accounts
3. C. Use AWS Organizations and AWS CloudFormation StackSets Deploy a CloudFormation template from an account that has the necessary IAM permissions
4. D. Use nested stacks with AWS CloudFormation templates Change the Region by using nested stacks

Correct Answer: C
https://aws.amazon.com/blogs/aws/new-use-aws-cloudformation-stacksets-for-multiple-accounts-in-an-aws-orga AWS Organizations allows the management of multiple AWS accounts as a single entity and AWS
CloudFormation StackSets allows creating, updating, and deleting stacks across multiple accounts and regions in an organization. This solution allows creating a single CloudFormation template that can be deployed across multiple accounts and regions, and also allows for the management of access and permissions for the different accounts through the use of IAM roles and policies in the management account.

A company wants to migrate its on-premises data center to the AWS Cloud. This includes thousands of virtualized Linux and Microsoft Windows servers, SAN storage, Java and PHP applications with MYSQL, and Oracle databases. There are many dependent services hosted either in the same data center or externally.

Which tools or services should solutions architect use to plan the cloud migration? (Choose three.)

1. A. AWS Application Discovery Service
2. B. AWS SMS
3. C. AWS x-Ray
4. D. AWS Cloud Adoption Readiness Tool (CART)
5. E. Amazon Inspector
6. F. AWS Migration Hub

Correct Answer: ADF

1. A. Use a spread placement grou
2. B. Set a minimum of eight instances for each Availability Zone.
3. C. Stop and start all the instances in the placement grou
4. D. Try the launch again.
5. E. Create a new placement grou

A company is planning to migrate its business-critical applications from an on-premises data center to AWS. The company has an on-premises installation of a Microsoft SQL Server Always On cluster. The company wants to migrate to an AWS managed database service. A solutions architect must design a heterogeneous database migration on AWS.
Which solution will meet these requirements?

1. A. Migrate the SQL Server databases to Amazon RDS for MySQL by using backup and restore utilities.
2. B. Use an AWS Snowball Edge Storage Optimized device to transfer data to Amazon S3. Set up Amazon RDS for MySQ
3. C. Use S3 integration with SQL Server features, such as BULK INSERT.
4. D. Use the AWS Schema Conversion Tool to translate the database schema to Amazon RDS for MeSQ
5. E. Then use AWS Database Migration Service (AWS DMS) to migrate the data from on-premises databases to Amazon RDS.
6. F. Use AWS DataSync to migrate data over the network between on-premises storage and Amazon S3. Set up Amazon RDS for MySQ
7. G. Use S3 integration with SQL Server features, such as BULK INSERT.

Correct Answer: C
https://aws.amazon.com/dms/schema-conversion-tool/
AWS Schema Conversion Tool (SCT) can automatically convert the database schema from Microsoft SQL Server to Amazon RDS for MySQL. This allows for a smooth transition of the database schema without any manual intervention. AWS DMS can then be used to migrate the data from the on-premises databases to the newly created Amazon RDS for MySQL instance. This service can perform a one-time migration of the data or can set up ongoing replication of data changes to keep the on-premises and AWS databases in sync.

A company recently started hosting new application workloads in the AWS Cloud. The company is using Amazon EC2 instances, Amazon Elastic File System (Amazon EFS) file systems, and Amazon RDS DB instances.
To meet regulatory and business requirements, the company must make the following changes for data backups:
* Backups must be retained based on custom daily, weekly, and monthly requirements.
* Backups must be replicated to at least one other AWS Region immediately after capture.
* The backup solution must provide a single source of backup status across the AWS environment.
* The backup solution must send immediate notifications upon failure of any resource backup.
Which combination of steps will meet this requirement with the LEAST amount of operational overhead? (Select THREE.)

1. A. Create an AWS Backup plan with a backup rule for each of the retention requirements.
2. B. Configure an AWS backup plan to copy backups to another Region.
3. C. Create an AWS Lambda function to replicate backups to another Region and send notification if a failure occurs.
4. D. Add an Amazon Simple Notification Service (Amazon SNS) topic to the backup plan to send a notification for finished jobs that have any status except BACKUP- JOB- COMPLETED.
5. E. Create an Amazon Data Lifecycle Manager (Amazon DLM) snapshot lifecycle policy for each of the retention requirements.
6. F. Set up RDS snapshots on each database.
