An application is deployed in AWS Elastic Beanstalk. You have a saved configuration from the test environment. Now you need to create pipelines for the performance test. You plan to apply the saved configuration. However, you find that some configurations need to be modified in the new environment. You do not want to modify the saved configuration YAML file. Which of the following options would you take to address this concern?

Answer options:

A.Recreate the saved configuration and modify the configurations using EB CLI command such as eb config save --cfg newcfg. 
B.Create a file with new configurations and put it in the .ebextentions folder. Include the .ebextentions folder under the project folder.
C.In the AWS Elastic Beanstalk console, modify the default settings for the performance test environment. Apply the saved configuration in the new pipelines.
D.Use EB CLI or AWS CLI to update the Elastic Beanstalk environment with new options such as aws elasticbeanstalk update-environment.

Correct Answer – D
Only the settings that are applied directly to the environment can override a saved configuration. Check the details in https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/command-options.html#configuration-options-precedence.
Option A is incorrect: Because you cannot modify settings when creating a saved configuration. Besides, the question mentions that the saved configuration should not be changed.
Option B is incorrect: Because the configuration file in the .ebextentions folder does not override a saved configuration.
Option C is incorrect: Because the default values are applied when they are not set at any of the above levels. Users cannot modify the default values in the AWS console.
Option D is CORRECT: Refer to https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/environment-configuration-methods-after.html for how to update the Elastic Beanstalk configurations.
