Topic #: 1
[All AWS DevOps Engineer Professional Questions]

A DevOps engineer wants to deploy a serverless web application that is based on AWS Lambda. The deployment must meet the following requirements:
✑ Provide staging and production environments.
✑ Restrict developers from accessing the production environment.
✑ Avoid hardcoding passwords in the Lambda functions.
✑ Store source code in AWS CodeCommit.
✑ Use AWS CodePipeline to automate the deployment.
What is the MOST operationally efficient solution that meets these requirements?

  • A. Create separate staging and production accounts to segregate deployment targets. Use AWS Key Management Service (AWS KMS) to store environment- specific values. Use CodePipeline to automate deployments with AWS CodeDeploy.
  • B. Create separate staging and production accounts to segregate deployment targets. Use Lambda environment variables to store environment-specific values. Use CodePipeline to automate deployments with AWS CodeDeploy.
  • C. Define tagging conventions for staging and production environments to segregate deployment targets. Use AWS Key Management Service (AWS KMS) to store environment-specific values. Use CodePipeline to automate deployments with AWS CodeDeploy.
  • D. Define tagging conventions for staging and production environments to segregate deployment targets. Use Lambda environment variables to store environment-specific values. Use CodePipeline to automate deployments with AWS CodeDeploy.

You can't use tagging to segregate deployment targets for Lambda. The docu here only says EC2 https://docs.aws.amazon.com/codedeploy/latest/userguide/instances-tagging.html

Lambda aliases should be used to sperate deplyment stateg. However, with the given options, the best way may be to use different accounts. A: Incorrect - KMS can't be used to store environment specific variable. Those are stored as environment variables, but can be encrypted with a KMS key. B: Correct C and D: Incorrect - Tagging can't be used to segregate deployment targets with Lambda

I would go with B as the question asks for MOST operational efficiency: https://aws.amazon.com/blogs/mt/multi-account-strategy-for-small-and-medium-businesses/ - In the Well Architected framework staging and prod should be separated for security and risk management (Limit scope of impact from adverse events) https://docs.aws.amazon.com/whitepapers/latest/organizing-your-aws-environment/benefits-of-using-multiple-aws-accounts.html

KMS is an encryption service, it is not secrets manager.. So you cannot store anything in KMS.. you can either segregate environments using accounts or using tags via policies.. So it would be either B or D.. I think I would go wi B.

One of the requirements is this: Restrict developers from accessing the production environment. D alone does not restrict users. B. meets all requirements.

Selected Answer: A
C and D are eliminated because we need two accounts. Tagging are not strict enough. AWS KMS is more efficient than Lambda environment variables. I used GCP KMS to manage environment-specific values. AWS KMS can also be used to manage environment-specific values. https://medium.com/cloudfordummies/securing-cloud-functions-part-1-using-aws-kms-for-environment-variables-1409597a38ba

B is the right answer and not D because we want to restrict developer access to the production environment and therefore having a separate account for production makes it more manageble.

Selected Answer: D
A,C are wrong. Since KSM can't store environment variable. The difference between B and D is separate environments by account or tagging. Per the requirement - the MOST operationally efficient, I will choice D.
