A reporting team receives files each day in an Amazon S3 bucket. The reporting team manually reviews and copies the files from this initial S3 bucket to an analysis S3 bucket each day at the same time to use with Amazon QuickSight. Additional teams are starting to send more files in larger sizes to the initial S3 bucket.
The reporting team wants to move the files automatically analysis S3 bucket as the files enter the initial S3 bucket. The reporting team also wants to use AWS Lambda functions to run pattern-matching code on the copied data. In addition, the reporting team wants to send the data files to a pipeline in Amazon SageMaker Pipelines.
What should a solutions architect do to meet these requirements with the LEAST operational overhead?

1. A. Create a Lambda function to copy the files to the analysis S3 bucke
2. B. Create an S3 event notification for the analysis S3 bucke
3. C. Configure Lambda and SageMaker Pipelines as destinations of the event notificatio
4. D. Configure s30bjectCreated:Put as the event type.
5. E. Create a Lambda function to copy the files to the analysis S3 bucke
6. F. Configure the analysis S3 bucket to send event notifications to Amazon EventBridge (Amazon CloudWatch Events). Configure an ObjectCreated rule in EventBridge (CloudWatch Events). Configure Lambda and SageMaker Pipelines as targets for the rule.
7. G. Configure S3 replication between the S3 bucket
8. H. Create an S3 event notification for the analysis S3 bucke
9. I. Configure Lambda and SageMaker Pipelines as destinations of the event notificatio
10. J. Configure s30bjectCreated:Put as the event type.
11. K. Configure S3 replication between the S3 bucket
12. L. Configure the analysis S3 bucket to send event notifications to Amazon EventBridge (Amazon CloudWatch Events). Configure an ObjectCreated rule in EventBridge (CloudWatch Events). Configure Lambda and SageMaker Pipelines as targets for the rule.

Correct Answer: D
This solution meets the requirements of moving the files automatically, running Lambda functions on the copied data, and sending the data files to SageMaker Pipelines with the least operational overhead. S3 replication can copy the files from the initial S3 bucket to the analysis S3 bucket as they arrive. The analysis S3 bucket can send event notifications to Amazon EventBridge (Amazon CloudWatch Events) when an object is created. EventBridge can trigger Lambda and SageMaker Pipelines as targets for the ObjectCreated rule. Lambda can run pattern-matching code on the copied data, and SageMaker Pipelines can execute a pipeline with the data files.
Option A is incorrect because creating a Lambda function to copy the files to the analysis S3 bucket is not necessary when S3 replication can do that automatically. It also adds operational overhead to manage the Lambda function. Option B is incorrect because creating a Lambda function to copy the files to the analysis S3 bucket is not necessary when S3 replication can do that automatically. It also adds operational overhead to manage the Lambda function. Option C is incorrect because using S3 event notification with multiple destinations can result in throttling or delivery failures if there are too many events. References:

A company needs to create an AWS Lambda function that will run in a VPC in the
company's primary AWS account. The Lambda function needs to access files that the company stores
in an Amazon Elastic File System (Amazon EFS) file system. The EFS file system is located in a secondary AWS account. As the company adds files to the file system the solution must scale to meet the demand.
Which solution will meet these requirements MOST cost-effectively?

1. A. Create a new EPS file system in the primary account Use AWS DataSync to copy the contents of the original EPS file system to the new EPS file system
2. B. Create a VPC peering connection between the VPCs that are in the primary account and the secondary account
3. C. Create a second Lambda function In the secondary account that has a mount that is configured for the file syste
4. D. Use the primary account's Lambda function to invoke the secondary account's Lambda function
5. E. Move the contents of the file system to a Lambda Layer’s Configure the Lambda layer's permissions to allow the company's secondary account to use the Lambda layer.

Correct Answer: B
This option is the most cost-effective and scalable way to allow the Lambda function in the primary account to access the EFS file system in the secondary account. VPC peering enables private connectivity between two VPCs without requiring gateways, VPN connections, or dedicated network connections. The Lambda function can use the VPC peering connection to mount the EFS file system as a local file system and access the files as needed. The solution does not incur additional data transfer or storage costs, and it leverages the existing EFS file system without duplicating or moving the data.
Option A is not cost-effective because it requires creating a new EFS file system and using AWS DataSync to copy the data from the original EFS file system. This would incur additional storage and data transfer costs, and it would not provide real-time access to the files.
Option C is not scalable because it requires creating a second Lambda function in the secondary account and configuring cross-account permissions to invoke it from the primary account. This would add complexity and latency to the solution, and it would increase the Lambda invocation costs.
Option D is not feasible because Lambda layers are not designed to store large amounts of data or provide file system access. Lambda layers are used to share common code or libraries across multiple Lambda functions. Moving the contents of the EFS file system to a Lambda layer would exceed the size limit of 250 MB for a layer, and it would not allow the Lambda function to read or write files to the layer.

1. A. Create an Amazon FSx for NetApp ONTAP file system Set each volume's tiering policy to ALL Import the raw data into the file system Mount the file system on the EC2 instances
2. B. Create an Amazon S3 bucket to stofe the raw data Create an Amazon FSx for Lustre file system that uses persistent SSD storage Select the option to import data from and export data to Amazon S3 Mount the file system on the EC2 instances
3. C. Create an Amazon S3 bucket to store the raw data Create an Amazon FSx for Lustre file system that uses persistent HDD storage Select the option to import data from and export data to Amazon S3 Mount the file system on the EC2 instances
4. D. Create an Amazon FSx for NetApp ONTAP file system Set each volume's tienng policy to NON
5. E. Import the raw data into the file system Mount the file system on the EC2 instances

Correct Answer: B
Create an Amazon S3 bucket to store the raw data Create an Amazon FSx for Lustre file system that uses persistent SSD storage Select the option to import data from and export data to Amazon S3 Mount the file system on the EC2 instances. Amazon FSx for Lustre uses SSD storage for sub-millisecond latencies and up to 6 GBps throughput, and can import data from and export data to Amazon S3. Additionally, the option to select persistent SSD storage will ensure that the data is stored on the disk and not lost if the file system is stopped.

11. K. Copy data to the device by using the AWS CL
12. L. Ship the device back to AWS for import into Amazon S3. Schedule AWS DataSync tasks to transfer the data to the FSx for Windows File Server file system.

Correct Answer: AD
A This option involves deploying DataSync agents on your on-premises file servers and using DataSync to transfer the data directly to the FSx for Windows File Server. DataSync ensures that file permissions are preserved during the migration process. D This option involves using an AWS Snowcone device, a portable data transfer device. You would connect the Snowcone device to your on-premises network, launch DataSync agents on the device, and schedule DataSync tasks to transfer the data to FSx for Windows File Server. DataSync handles the migration process while preserving file permissions.
