This video tutorial covers the setup and deployment of an AWS Lambda function integrated with API Gateway to perform CRUD operations on a DynamoDB table. It explains the event-driven model of Lambda, the configuration of permissions, and the creation of roles and policies. The tutorial also includes a step-by-step guide to implementing and deploying the Lambda function code, emphasizing the importance of permissions for interacting with DynamoDB.

What is the primary role of AWS Lambda in the context of event-driven computing?

• To manage network traffic

• To provide a user interface

• To execute code in response to events

• To store data persistently

• Amazon S3

• Amazon EC2

• API Gateway

• Amazon RDS

What operations does the Lambda function perform on the DynamoDB table?

• Backup and restore

• CRUD operations

• Network configuration

• Data encryption

Why is it important to set up permissions for the Lambda function?

• To reduce the cost of AWS services

• To ensure the function can interact with DynamoDB

• To increase the function's execution speed

• To improve the user interface

What is the purpose of creating a new role with a policy template for the Lambda function?

• To enhance the function's security

• To enable the function to interact with DynamoDB

• To provide a graphical user interface

• To allow the function to access external APIs

What is the handler method in a Lambda function?

• A method to execute when the function is invoked

• A method to manage network traffic

• A method to store data

• A method to provide user authentication

What are the two parameters taken by the handler method in a Lambda function?

• Event and context
