Exam AWS Certified Developer Associate topic 1 question 4 discussion

Exam question from Amazon's AWS Certified Developer Associate
Question #: 4
Topic #: 1
[All AWS Certified Developer Associate Questions]

A developer is testing an AWS Lambda function by using the AWS Serverless Application Model (AWS SAM) local CLI. The application that is implemented by the
Lambda function makes several AWS API calls by using the AWS software development kit (SDK). The developer wants to allow the function to make AWS API calls in a test AWS account from the developer's laptop.
What should the developer do to meet these requirements?

  • A. Edit the template.yml file. Add the AWS_ACCESS_KEY_ID property and the AWS_SECRET_ACCESS_KEY property in the Globals section.
  • B. Add a test profile by using the aws configure command with the --profile option. Run AWS SAM by using the sam local invoke command with the -profile option.
  • C. Edit the template.yml tile. For the AWS::Serverless::Function resource, set the role to an IAM role in the AWS account.
  • D. Run the function by using the sam local invoke command. Override the AWS_ACCESS_KEY_ID parameter and the AWS_SECRET_ACCESS_KEY parameter by specifying the --parameter-overrides option.

Selected Answer: B
Agree on B. You use the configure command. Alternatively, set up credentials in the credentials file. https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-getting-started-set-up-credentials.html

Selected Answer: B
A) Eliminated: template.yml is meant to define AWS resources and configuration for the deployment, not for storing credentials. Hardcoding credentials in a file is a security risk and is against AWS best practices.

C) Eliminated: IAM role is only applied during execution in the AWS environment, not locally.

D) Eliminated: The --parameter-overrides option is for passing CloudFormation template parameters, not AWS credentials. https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/sam-cli-command-reference-sam-local-invoke.html

B) Correct --profile, This allows SAM to use the credentials from the specified profile, enabling the Lambda function to make AWS API calls in the test account. sam local invoke --profile test-profile

Selected Answer: B
A) Global section is used for defining configurations shared across multiple resources https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/sam-specification-template-anatomy-globals.html C) To me, setting the profile for your function do not affect the credentials used from the sam cli D) the --parameter-override is used to overrides encoded as key-value pairs in the CloudFormation template https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/sam-cli-command-reference-sam-local-invoke.html B) looks a viable option https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/prerequisites.html#prerequisites-configure-credentials

Rather than use the access keys and secret key (in env, in the cmd, or with aws configure) I would recomend to configure and use the profiles. (There will be a file in .aws folder called config) and it looks like: [profile test-profile] role_arn = arn:aws:iam::XXXXXXXXX:role/ec2AccessRole source_profile = default We can run the command by specifing the following parameter: "--profile test-profile" to have the rights associate with the ec2AccessRole
