An application allows a manufacturing site to upload files. Each uploaded 3 GB file is processed to extract metadata, and this process takes a few seconds per file. The frequency at which the uploads happen is unpredictable. For instance, there may be no updates for hours, followed by several files being uploaded concurrently.
Which AWS service will meet the above requirements?
Amazon S3
Amazon EBS
Amazon EFS
Amazon Storage Gateway VTL
What architecture addresses this workload in the most cost efficient manner?
Use a Kinesis Data Delivery Stream to store the file. Use Lambda for processing.
Use an SQS queue to store the file, to be accessed by a fleet of EC2 Instances.
Store the file in an EBS volume, which can then be accessed by another EC2 Instance for processing.
Store the file in an S3 bucket. Use Amazon S3 event notification to invoke a Lambda function for file processing.
A company is to run a service on AWS to provide offsite backups for images on laptops and phones.

An application reads and writes objects to an S3 bucket. When the application is fully deployed, the read/write traffic is very high.
How should the architect maximize the Amazon S3 performance?
Use as many S3 prefixes as you need in parallel to achieve the required throughput.
Use the STANDARD_IA storage class.
Prefix each object name with a hex hash key along with the current data.
Enable versioning on the S3 bucket.
A Solutions Architect is designing a highly scalable system to track records. These records must remain available for immediate download for up to three months and then must be deleted.

Store the files in Amazon S3 and create a Lifecycle Policy to remove files after 3 months
Store the files in Amazon Glacier and create a Lifecycle Policy to remove files after 3 months
Store the files in Amazon EFS and create a Lifecycle Policy to remove files after 3 months
A company needs to store images that are uploaded by users via a mobile application. There is also a need to ensure that a security measure is in place to avoid the data loss.
