Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 51
Topic #: 2

Auto Scaling can automatically adjust the number of ECS instances based on user-defined scaling rules to meet service needs. If a user cannot predict service changes or does not have enough history data, he/she can still use dynamic scaling mode to automatically add/remove ECS instances based on certain Cloud Monitor performance metrics (such as the CPU utilization rate)

I agree with Jackie, the description matches the 'True' answer. Although I wonder how the system would know what metrics to use if the user has no history data. Guess it just goes with the defaults?

I think it must use some default metrics in that case.

Haha, the option B is as false as my grandma's dentures. Of course Auto Scaling can handle dynamic service needs, that's like the whole point of it!

Hmm, I'm not sure about this one. Doesn't Auto Scaling require some historical data to set up the scaling rules? If the user doesn't have that, how can it work automatically?

The description sounds accurate. Auto Scaling can definitely help handle unpredictable service changes by automatically scaling up or down based on performance metrics. Option A seems to be the correct answer.
