A developer wants an AWS Lambda function to automatically process messages that arrive in an Amazon SQS queue. What is the correct way to connect the queue to the function?

A developer must retrieve all items for a specific customer ID from a large DynamoDB table efficiently, using the table's partition key. Which operation should they use?

An application must query a DynamoDB table by an attribute that is NOT the table's primary key (for example, by email address). Which feature enables this alternate query pattern efficiently?

Two concurrent processes may update the same DynamoDB item at the same time, and the developer must prevent one update from silently overwriting the other. Which technique addresses this?

A developer wants to expose a set of AWS Lambda functions as a RESTful HTTP API to clients, with request routing, throttling, and authorization. Which service should they use as the API front end?

A developer needs to coordinate a multi-step workflow of several Lambda functions with branching, retries, and state passed between steps, without writing custom orchestration code. Which service is designed for this?

A developer must upload very large objects (several gigabytes) to Amazon S3 reliably, with the ability to retry individual parts if the network fails. Which approach should they use?

Whenever an item is inserted or modified in a DynamoDB table, a developer wants to trigger a Lambda function to process that change in near real time. Which feature enables this?

An order-processing application must process messages strictly in order and ensure no message is processed more than once. Which Amazon SQS configuration should the developer choose?

Consumers occasionally process the same SQS message twice because a slow consumer's message becomes visible again before it finishes. Which setting should the developer adjust so a message stays hidden long enough to be processed once?
