NEW QUESTION # 37
You're developing a serverless application using AWS Lambda that requires access to environment variables for configuration purposes. How would you securely manage and access these environment variables within your Lambda functions?

  • A. Configure environment variables within the AWS Lambda console.
  • B. Use AWS Secrets Manager to store and retrieve sensitive environment variables.
  • C. Utilize AWS Parameter Store to manage environment variables as parameters.
  • D. Store environment variables directly in the Lambda function's code.
  • E. Store environment variables in a separate file and upload it along with the Lambda function's code.

Answer: B,C

Explanation:
The most secure and recommended approaches for managing environment variables in AWS Lambda are to use AWS Secrets Manager (B) and AWS Parameter Store (D). Secrets Manager is specifically designed for storing and retrieving sensitive data like API keys, passwords, and other confidential information. Parameter Store allows you to manage configuration parameters, including environment variables, in a centralized and hierarchical manner. Storing environment variables directly in the code (A) is insecure. Configuring them in the Lambda console (C) is not suitable for managing sensitive data. Storing them in a separate file (E) is less secure and less manageable.

  • D. HorizontalPodAutoscaler
  • E. Deployment

  • D. Use a shared secret stored in an environment variable within the microservice pod
  • E. Use an API gateway to proxy requests between the services.

It allows for secure communication without exposing sensitive credentials directly within the microservice code.
