Topic 1 Question 124
An organization is storing large files in Amazon S3, and is writing a web application to display meta-data about the files to end-users. Based on the metadata a user selects an object to download. The organization needs a mechanism to index the files and provide single-digit millisecond latency retrieval for the metadata.
What AWS service should be used to accomplish this?
Amazon DynamoDB
Amazon EC2
AWS Lambda
Amazon RDS

In this scenario, the metadata about the files can be stored in a DynamoDB table with a primary key based on the metadata attributes. This would enable the organization to quickly query and retrieve metadata about the files in real-time, with single-digit millisecond latency.

Amazon DynamoDB is a highly scalable and fully managed NoSQL database service that can provide fast and consistent performance at any scale. It is a suitable choice for indexing and storing metadata associated with files.
