Question #: 85
Topic #: 7
[All ACA-Cloud1 Questions]

Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies. It supports adding existing ECS instances into the scaling group, whose status however must be ________.

Show Suggested Answer Hide 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.

Auto Scaling? More like Auto Snoozing, am I right? But seriously, A) Running is the only logical answer here. Can't scale what ain't moving!

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.

So, the status of the existing ECS instances must be Running to be added to the scaling group.

Yeah, it wouldn't make sense to add stopped instances into the scaling group.

I agree, Auto Scaling would need instances that are already running to adjust resources.

I'm not sure, but I think it might be C) Stopped, because maybe you can add instances that are stopped and then start them.

I think the answer is A) Running. Auto Scaling needs instances that are actively running to scale them up or down based on demand.
