Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 104 discussion

I think AWS wants you to know is the below. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-types.html

A = you don't need to create a new application (instead you could create a new environment in the existing application) B = traffic-split is used to deploy a new version of the app, not to scale out C = correct D = rebuild does not allow to change environment configuration https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/environment-management-rebuild.html

You can change your environment type to a single-instance or load-balanced, scalable environment by editing your environment's configuration.

C. Modify the existing environment’s capacity configuration to use a load-balanced environment type. Select all Availability Zones. Add a scale-out rule that will run if the average CPU utilization is over 85% for 5 minutes.

You can change the existing environment from single instance to load balanced. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-types.html

Option C

C here https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/GettingStarted.EditConfig.html

I prefer C

Option C is very correct. See https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-types.html for confirmation

its a C

Anybody know why we should select all AZs?

Modify the existing environment’s capacity configuration to use a load-balanced environment type.

You can change your environment type to a single-instance or load-balanced, scalable environment by editing your environment's configuration. In some cases, you might want to change your environment type from one type to another. For example, let's say that you developed and tested an application in a single-instance environment to save costs. When your application is ready for production, you can change the environment type to a load-balanced, scalable environment so that it can scale to meet the demands of your customers. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-types.html

A is wrong. no need to re create new EB env when the question is asking to mitigate probable performance issues based on current compute consumption of >=85%

It's C. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-types.html#using-features.managing.changetype
