A company has applications in an AWS account that is named Source. The account is in an organization in AWS Organizations. One of the applications uses AWS Lambda functions and store’s inventory data in an Amazon Aurora database. The application deploys the Lambda functions by using a deployment package. The company has configured automated backups for Aurora.
The company wants to migrate the Lambda functions and the Aurora database to a new AWS account that is named Target. The application processes critical data, so the company must minimize downtime.
Which solution will meet these requirements?

1. A. Download the Lambda function deployment package from the Source accoun
2. B. Use the deployment package and create new Lambda functions in the Target accoun
3. C. Share the automated Aurora DB cluster snapshot with the Target account.
4. D. Download the Lambda function deployment package from the Source accoun
5. E. Use the deployment package and create new Lambda functions in the Target account Share the Aurora DB cluster with the Target account by using AWS Resource Access Manager {AWS RAM). Grant the Target account permission to clone the Aurora DB cluster.
6. F. Use AWS Resource Access Manager (AWS RAM) to share the Lambda functions and the Aurora DB cluster with the Target accoun
7. G. Grant the Target account permission to clone the Aurora DB cluster.
8. H. Use AWS Resource Access Manager (AWS RAM) to share the Lambda functions with the Target accoun
9. I. Share the automated Aurora DB cluster snapshot with the Target account.

Correct Answer: C
This solution uses a combination of AWS Resource Access Manager (RAM) and automated backups to migrate the Lambda functions and the Aurora database to the Target account while minimizing downtime. In this solution, the Lambda function deployment package is downloaded from the Source account and used to create new Lambda functions in the Target account. The Aurora DB cluster is shared with the Target account using AWS RAM and the Target account is granted permission to clone the Aurora DB cluster, allowing for a new copy of the Aurora database to be created in the Target account. This approach allows for the data to be migrated to the Target account while minimizing downtime, as the Target account can use the cloned Aurora database while the original Aurora database continues to be used in the Source account.

A solutions architect is reviewing a company's process for taking snapshots of Amazon RDS DB instances. The company takes automatic snapshots every day and retains the snapshots for 7 days.
The solutions architect needs to recommend a solution that takes snapshots every 6 hours and retains the snapshots for 30 days. The company uses AWS Organizations to manage all of its AWS accounts. The company needs a consolidated view of the health of the RDS snapshots.
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Turn on the cross-account management feature in AWS Backu
2. B. Create a backup plan that specifies the frequency and retention requirement
3. C. Add a tag to the DB instance
4. D. Apply the backup plan by using tag
5. E. Use AWS Backup to monitor the status of the backups.
6. F. Turn on the cross-account management feature in Amazon RD
7. G. Create a snapshot global policy that specifies the frequency and retention requirement
8. H. Use the RDS console in the management account to monitor the status of the backups.
9. I. Turn on the cross-account management feature in AWS CloudFormatio
10. J. From the management account, deploy a CloudFormation stack set that contains a backup plan from AWS Backup thatspecifies the frequency and retention requirement
11. K. Create an AWS Lambda function in the management account to monitor the status of the backup
12. L. Create an Amazon EventBridge rule in each account to run the Lambda function on a schedule.
13. M. Configure AWS Backup in each accoun
14. N. Create an Amazon Data Lifecycle Manager lifecycle policy that specifies the frequency and retention requirement
15. O. Specify the DB instances as the target resourc
16. P. Use the Amazon Data Lifecycle Manager console in each member account to monitor the status of the backups.

Correct Answer: A
Turning on the cross-account management feature in AWS Backup will enable managing and monitoring backups across multiple AWS accounts that belong to the same organization in AWS Organizations1. Creating a backup plan that specifies the frequency and retention requirements will enable taking snapshots every 6 hours and retaining them for 30 days2. Adding a tag to the DB instances will enable applying the backup plan by using tags2. Using AWS Backup to monitor the status of the backups will enable having a consolidated view of the health of the RDS snapshots1.

A company operates an on-premises software-as-a-service (SaaS) solution that ingests several files daily. The company provides multiple public SFTP endpoints to its customers to facilitate the file transfers. The customers add the SFTP endpoint IP addresses to their firewall allow list for outbound traffic. Changes to the SFTP endmost IP addresses are not permitted.
The company wants to migrate the SaaS solution to AWS and decrease the operational overhead of the file transfer service.
Which solution meets these requirements?

1. A. Register the customer-owned block of IP addresses in the company's AWS accoun
2. B. Create Elastic IP addresses from the address pool and assign them to an AWS Transfer for SFTP endpoin
3. C. Use AWS Transfer to store the files in Amazon S3.
4. D. Add a subnet containing the customer-owned block of IP addresses to a VPC Create Elastic IP addresses from the address pool and assign them to an Application Load Balancer (ALB). Launch EC2 instances hosting FTP services in an Auto Scaling group behind the AL
5. E. Store the files in attached Amazon Elastic Block Store (Amazon EBS) volumes.
6. F. Register the customer-owned block of IP addresses with Amazon Route 53. Create alias records inRoute 53 that point to a Network Load Balancer (NLB). Launch EC2 instances hosting FTP services in an Auto Scaling group behind the NL
7. G. Store the files in Amazon S3.
8. H. Register the customer-owned block of IP addresses in the company's AWS accoun
9. I. Create Elastic IP addresses from the address pool and assign them to an Amazon S3 VPC endpoin
10. J. Enable SFTP support on the S3 bucket.

Correct Answer: A
Bring your own IP addresses (BYOIP) You can bring part or all of your publicly routable IPv4 or IPv6 address range from your on-premises network to your AWS account. You continue to own the address range, but AWS advertises it on the internet by default. After you bring the address range to AWS, it appears in your AWS account as an address pool. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-byoip.html AWS Transfer for SFTP enables you to easily move your file transfer workloads that use the Secure Shell File Transfer Protocol (SFTP) to AWS without needing to modify your applications or manage any SFTP servers. https://aws.amazon.com/about-aws/whats-new/2018/11/aws-transfer-for-sftp-fully-managed-sftp-for-s3/

A company operates quick-service restaurants. The restaurants follow a predictable model with high sales traffic for 4 hours daily Sales traffic is lower outside of those peak hours.
The point of sale and management platform is deployed in the AWS Cloud and has a backend that is based on Amazon DynamoDB. The database table uses provisioned throughput mode with 100.000 RCUs and 80.000 WCUs to match known peak resource consumption.
The company wants to reduce its DynamoDB cost and minimize the operational overhead for the IT staff. Which solution meets these requirements MOST cost-effectively?

1. A. Reduce the provisioned RCUs and WCUs
2. B. Change the DynamoDB table to use on-demand capacity.
3. C. Enable Dynamo DB auto scaling tor the table
4. D. Purchase 1-year reserved capacity that is sufficient to cover the peak load for 4 hours each day

Correct Answer: C
https://aws.amazon.com/blogs/database/amazon-dynamodb-auto-scaling-performance-and-cost-optimization-at- "As you can see, there are compelling reasons to use DynamoDB auto scaling with actively changing traffic. Auto scaling responds quickly and simplifies capacity management, which lowers costs by scaling your table’s provisioned capacity and reducing operational overhead."
