A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple
continents. The average volume of data that the company collects from each site daily is 500 GB. Each
site has a high-speed Internet connection.
The company wants to aggregate the data from all these global sites as quickly as possible in a single
Amazon S3 bucket. The solution must minimize operational complexity.
Which solution meets these requirements?
Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly
upload site data to the destination S3 bucket.

JSON format in an Amazon S3 bucket. Queries will be simple and will run on-demand. A solutions
architect needs to perform the analysis with minimal changes to the existing architecture.
What should the solutions architect do to meet these requirements with the LEAST amount of
operational overhead?
Use Amazon Athena directly with Amazon S3 to run the queries as needed.

A company is hosting a web application on AWS using a single Amazon EC2 instance that stores user-
uploaded documents in an Amazon EBS volume. For better scalability and availability, the company
duplicated the architecture and created a second EC2 instance and EBS volume in another Availability
Zone, placing both behind an Application Load Balancer. After completing this change, users reported
that, each time they refreshed the website, they could see one subset of their documents or the other,
but never all of the documents at the same time.
What should a solutions architect propose to ensure users see all of their documents at once?
Copy the data from both EBS volumes to Amazon EFS. Modify the application to save new
documents to Amazon EFS.
