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)

Wait, can it really adjust without any history? Sounds sketchy.

Alright, let's see. If the user can't predict service changes or doesn't have enough history data, they can still use dynamic scaling to automatically scale the instances. Sounds like the answer is A, True.

This question is testing our understanding of Auto Scaling's capabilities. I'll make sure to read through the details closely and think through the implications before selecting an answer.

Okay, I think I got it. The key is that Auto Scaling can use dynamic scaling mode to add/remove instances based on performance metrics, even if the user doesn't have a lot of historical data. I'm feeling confident about this one.

Hmm, I'm a bit confused. Does this mean Auto Scaling can automatically scale up and down the instances without any user-defined rules? I'll need to re-read this carefully.

This seems pretty straightforward. Auto Scaling can automatically adjust the number of ECS instances based on performance metrics, even if the user can't predict service changes or doesn't have enough history data.

This seems like a straightforward question about using different Salesforce Marketing Cloud tools to process and send welcome messages to new customers. I'll need to carefully consider the capabilities of each tool to determine the best solution.

I'm leaning towards option E. Exporting the original app as unmanaged, importing it into a test environment, and then deploying it back to production seems like the safest way to ensure we get an exact copy without any issues.

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?
