An adventure company has launched a new feature on its mobile app. Users can use the feature to upload their hiking and rafting 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?

A.

Configure S3 Intelligent-Tiering on the S3 bucket.

B.

Configure an S3 Lifecycle policy to transition image objects and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days.

C.

Replace Amazon S3 with an Amazon Elastic File System (Amazon EFS) file system that is mounted on Amazon EC2 instances.

D.

Add a Cache-Control: max-age header to the S3 image objects and S3 video objects. Set the header to 30 days.

An image-processing company has a web application that users use to upload images. The application uploads the images into an Amazon S3 bucket. The company has set up S3 event notifications to publish the object creation events to an Amazon SQS standard queue. The SQS queue serves as the event source for an AWS Lambda function that processes the images and sends the results to users through email.

Users report that they are receiving multiple email messages for every uploaded image. A solutions architect determines that SQS messages are invoking the Lambda function more than once, resulting in multiple email messages.

What should the solutions architect do to resolve this issue with the LEAST operational overhead?

A.

Set up long polling in the SQS queue by increasing the ReceiveMessage wait time to 30 seconds.

B.

Change the SQS standard queue to an SQS FIFO queue. Use the message deduplication ID to discard duplicate messages.

C.

Increase the visibility timeout in the SQS queue to a value that is greater than the total of the function timeout and the batch window timeout.

D.

Modify the Lambda function to delete each message from the SQS queue immediately after the message is read before processing.

A financial services company must retain log data for 1 year. The company stores log files in an Amazon S3 bucket and wants to prevent any user from deleting or overwriting the log files during this period. The data must remain available for read-only requests.

A.

Enable S3 Versioning on the bucket. Use Object Lock in compliance mode with a 1-year retention period.

B.

Enable S3 Transfer Acceleration on the bucket. Create an S3 Lifecycle Configuration rule to move objects to Amazon S3 Glacier Flexible Retrieval after 1 year.

C.

Enable S3 Versioning on the bucket. Create an S3 Lifecycle Configuration rule to move objects to Amazon S3 Glacier Flexible Retrieval after 1 year.

D.

Create an AWS Lambda function to programmatically check the timestamp of S3 data and to move the data to Amazon S3 Glacier Deep Archive if the data is older than 1 year.
