Lambda Flashcards
Q: What solution will reduce the startup latency for Java 11 Lambda functions, reduce cold starts, and be cost-effective?
A: Configure Lambda SnapStart.
Q: How should a solutions architect design a serverless application that needs to execute long-running tasks without impacting the application’s performance?
A: Use an Amazon SQS queue to receive the tasks. Configure an AWS Lambda function to process the tasks from the queue.
Q: What should a solutions architect do to ensure that an AWS Lambda function has the necessary permissions to access an Amazon DynamoDB table securely?
A: Create an IAM role with the required permissions to read and write from the DynamoDB tables. Attach the role to the Lambda function.
Q: How should a solutions architect design a scalable and fault-tolerant solution to process messages received by an application using Amazon DynamoDB?
A: Use an Amazon SQS FIFO queue to receive the messages. Configure the queue to trigger an AWS Lambda function to process the messages and store the results in DynamoDB.
Q: What solution will meet the requirements of processing streaming data from IoT sensors in a scalable and cost-effective manner?
A: Use AWS Lambda with a Python script to process the data.
Q: How should a solutions architect design a serverless application to handle unpredictable traffic and minimize operational overhead?
A: Use Amazon API Gateway to expose the application’s API and invoke AWS Lambda functions to handle the application logic.
Q: What should a solutions architect do to improve the performance and scalability of a serverless application that uses AWS Lambda and Amazon API Gateway?
A: Configure provisioned concurrency for the Lambda function that handles the API requests.
