Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
. You have decided to change the Instance type for instances running in your application tier that are using Auto Scaling. In which area below would you change the instance type definition?
A
Auto Scaling launch configuration
B
Auto Scaling group
C
Auto Scaling policy
D
Auto Scaling tags
Explanation: 

Detailed explanation-1: -You can use an instance refresh to update the instances in your Auto Scaling group instead of manually replacing instances a few at a time. This can be useful when a configuration change requires you to replace instances, and you have a large number of instances in your Auto Scaling group.

Detailed explanation-2: -AWS does not allow to edit launch configuration. If you notice, we define instance type at time of launch configuration. So if you want to change instance type in Auto Scaling group than you need to create new launch configuration for that.

Detailed explanation-3: -Its the Launch Configuration. You define here AMI, InstanceType etc..

Detailed explanation-4: -Back up the data on your original instance. Launch a new instance with a configuration that is compatible with the new instance type that you want, and attach any EBS volumes that were attached to your original instance. More items
