A company is creating a sequel for a popular online game. A large number of users from all over the world will play the game within the first week after launch. Currently, the game consists of the following components deployed in a single AWS Region:
• Amazon S3 bucket that stores game assets
• Amazon DynamoDB table that stores player scores
A solutions architect needs to design a multi-Region solution that will reduce latency improve reliability, and require the least effort to implement
What should the solutions architect do to meet these requirements?

1. A. Create an Amazon CloudFront distribution to serve assets from the S3 bucket Configure S3Cross-Region Replication Create a new DynamoDB able in a new Region Use the new table as a replica target tor DynamoDB global tables.
2. B. Create an Amazon CloudFront distribution to serve assets from the S3 bucke
3. C. Configure S3Same-Region Replicatio
4. D. Create a new DynamoDB able m a new Regio
5. E. Configure asynchronous replication between the DynamoDB tables by using AWS Database Migration Service (AWS DMS) with change data capture (CDC)
6. F. Create another S3 bucket in a new Region and configure S3 Cross-Region Replication between the buckets Create an Amazon CloudFront distribution and configure origin failover with two origins accessing the S3 buckets in each Regio
7. G. Configure DynamoDB global tables by enabling Amazon DynamoDB Streams, and add a replica table in a new Region.
8. H. Create another S3 bucket in the same Region, and configure S3 Same-Region Replication between the buckets- Create an Amazon CloudFront distribution and configure origin failover with two origin accessing the S3 buckets Create a new DynamoDB table m a new Region Use the new table as a replica target for DynamoDB global tables.

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 is using AWS Organizations to manage multiple AWS accounts. For security purposes, the company requires the creation of an Amazon Simple Notification Service (Amazon SNS) topic that enables integration with a third-party alerting system in all the Organizations member accounts.
A solutions architect used an AWS CloudFormation template to create the SNS topic and stack sets to automate the deployment of Cloud Formation stacks. Trusted access has been enabled in Organizations.
What should the solutions architect do to deploy the CloudFormation StackSets in all AWS accounts?

1. A. Create a stack set in the Organizations member account
2. B. Use service-managed permission
3. C. Set deployment options to deploy to an organizatio
4. D. Use CloudFormation StackSets drift detection.
5. E. Create stacks in the Organizations member account
6. F. Use self-service permission
7. G. Set deploymentoptions to deploy to an organizatio
8. H. Enable the CloudFormation StackSets automatic deployment.
9. I. Create a stack set in the Organizations management accoun
10. J. Use service-managed permission
11. K. Set deployment options to deploy to the organizatio
12. L. Enable CloudFormation StackSets automatic deployment.
13. M. Create stacks in the Organizations management accoun
14. N. Use service-managed permission
15. O. Set deployment options to deploy to the organizatio
16. P. Enable CloudFormation StackSets drift detection.

A financial company needs to create a separate AWS account for a new digital wallet application. The company uses AWS Organizations to manage its accounts. A solutions architect uses the 1AM user Supportl from the management account to create a new member account with finance1@example.com as the email address.
What should the solutions architect do to create IAM users in the new member account?

1. A. Sign in to the AWS Management Console with AWS account root user credentials by using the64-character password from the initial AWS Organizations email senttofinance1@example.co
2. B. Set up the IAM users as required.
3. C. From the management account, switch roles to assume the OrganizationAccountAccessRole role with the account ID of the new member accoun
4. D. Set up the IAM users as required.
5. E. Go to the AWS Management Console sign-in pag
6. F. Choose "Sign in using root account credentials." Sign in in by using the email address finance1@example.com and the management account's root passwor
7. G. Set up the IAM users as required.
8. H. Go to the AWS Management Console sign-in pag
9. I. Sign in by using the account ID of the new member account and the Supportl IAM credential
10. J. Set up the IAM users as required.

Correct Answer: D
The best solution is to turn on the Concurrency Scaling feature for the Amazon Redshift cluster. This feature allows the cluster to automatically add additional capacity to handle bursts of read queries without affecting the performance of write queries. The additional capacity is transparent to the users and is billed separately based on the usage. This solution meets the business requirements of servicing read and write queries at all times and is also cost-effective compared to the other options, which involve provisioning additional resources or resizing the cluster.

An adventure company has launched a new feature on its mobile app. Users can use the feature to upload their hiking and ratting photos and videos anytime. The photos and videos are stored in Amazon S3 Standard storage in an S3 bucket and are served through Amazon CloudFront.
The company needs to optimize the cost of the storage. A solutions architect discovers that most of the uploaded photos and videos are accessed infrequently after 30 days. However, some of the uploaded photos and videos are accessed frequently after 30 days. The solutions architect needs to implement a solution that maintains millisecond retrieval availability of the photos and videos at the lowest possible cost.
Which solution will meet these requirements?

1. A. Configure S3 Intelligent-Tiering on the S3 bucket.
2. B. Configure an S3 Lifecycle policy to transition image objects and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days.
3. C. Replace Amazon S3 with an Amazon Elastic File System (Amazon EFS) file system that is mounted on Amazon EC2 instances.
4. D. Add a Cache-Control: max-age header to the S3 image objects and S3 video object
5. E. Set the header to 30 days.

Correct Answer: A
Amazon S3 Intelligent-Tiering is a storage class that automatically moves objects between two access tiers based on changing access patterns. Objects that are accessed frequently are stored in the frequent access tier and objects that are accessed infrequently are stored in the infrequent access tier. This allows for cost optimization without requiring manual intervention. This makes it an ideal solution for the scenario described, as it can automatically move objects that are infrequently accessed after 30 days to a lower-cost storage tier while still maintaining millisecond retrieval availability.
