ARunning

BCreated

CStopped

DPreparing

Show Suggested Answer

Suggested Answer: A

A is the correct answer because Auto Scaling supports adding existing ECS instances into the scaling group, whose status however must be running. Running means that the ECS instance is in a normal state and can provide services. Auto Scaling does not support adding ECS instances that are in other states, such as created, stopped, or preparing. Created means that the ECS instance has been created but has not been started yet. Stopped means that the ECS instance has been stopped and cannot provide services.Preparing means that the ECS instance is being initialized and cannot provide services12

B, C, and D are incorrect answers because they are not valid states for adding existing ECS instances into the scaling group.

Definitely A) Running. I can't imagine Auto Scaling being able to do much with instances that are in a Stopped or Preparing state. They need to be active and ready to go.

Hmm, I'm not sure. I would have guessed C) Stopped, since Auto Scaling could potentially bring stopped instances back online when needed. But A) Running makes sense too.
