You are planning to develop and deploy a Node.js Lambda function.
The code has a dependency on a lot of third-party libraries.
Which of the following needs to be done to ensure that the code can be executed in the AWS Lambda service?

A. B. C. D.Answer - B.
The AWS Documentation mentions the following.
If you are writing code that uses other resources, such as a graphics library for image processing, or you want to use the AWS CLI instead of the console, you need to first create the Lambda function deployment package, and then use the console or the CLI to upload the package.
Because of what is mentioned in the AWS Documentation, all other options are invalid.
For more information on creating the deployment package, please refer to the below URL-
https://docs.aws.amazon.com/lambda/latest/dg/nodejs-create-deployment-pkg.htmlWhen developing and deploying a Node.js Lambda function that depends on third-party libraries, you need to create a deployment package that includes your code and the required third-party libraries. Therefore, the correct answer is B.
AWS Lambda is a serverless compute service that allows you to run your code without provisioning or managing servers. When you create a Lambda function, you need to provide the code that will be executed by the service. If your code has dependencies on third-party libraries, you need to include them in the deployment package.
A) Installing third-party libraries in the Lambda service is not possible. AWS Lambda provides a runtime environment with specific versions of programming languages and libraries installed. You cannot install additional libraries at runtime.
C) Using CloudFormation templates to deploy third-party libraries is not the best approach, as CloudFormation is a service for defining and deploying AWS infrastructure resources. While you can use CloudFormation to create Lambda functions, it is not necessary to use it to deploy libraries.
D) Using an IAM role with the required permissions on those libraries is not applicable in this case. IAM roles are used to manage permissions for AWS resources and services, not for third-party libraries.
In summary, the correct answer is B: Create a deployment package with your code and the third-party libraries. You can create the deployment package using a tool like npm, which allows you to package your code and dependencies together. Once you have the deployment package, you can upload it to AWS Lambda to create your function.
