You have deployed an application to AWS which makes use of Autoscaling to launch new instances. You now want to change the instance type for the new instances. Which of the following is one of the action items to achieve this deployment?

A.
Use Elastic Beanstalk to deploy the new application with the new instance type
Answers
A.
Use Elastic Beanstalk to deploy the new application with the new instance type
B.
Use Cloudformation to deploy the new application with the new instance type
Answers
B.
Use Cloudformation to deploy the new application with the new instance type
C.
Create a new launch configuration with the new instance type
Answers
C.
Create a new launch configuration with the new instance type
D.
Create new EC2 instances with the new instance type and attach it to the Autoscaling Group
Answers
D.
Create new EC2 instances with the new instance type and attach it to the Autoscaling Group
Suggested answer: C

Explanation:

The ideal way is to create a new launch configuration, attach it to the existing Auto Scaling group, and terminate the running instances. Option A is invalid because Clastic beanstalk cannot launch new instances on demand. Since the current scenario requires Autoscaling, this is not the ideal option Option B is invalid because this will be a maintenance overhead, since you just have an Autoscaling Group. There is no need to create a whole Cloudformation template for this. Option D is invalid because Autoscaling Group will still launch CC2 instances with the older launch configuration.
