Alibaba ACP-Cloud1 Exam - Topic 7 Question 87 Discussion

Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 87
Topic #: 7

When using Auto Scaling, you want to add or remove ECS instances based on the utilization rate of computing resources. For example, you want to remove one ECS instance when the average CPU utilization rate is not greater than 30%. In this case, you need to set the scaling rule ''Remove 1 ECS instance'' and ____________ to finish the configuration.

ACreate a scaling configuration

BConfigure the attributes of the scaling group

CCreate a scheduled task

DCreate an event-triggered task

Show Suggested Answer

Suggested Answer: D

An event-triggered task is necessary when creating scaling rules based on specific metrics such as CPU utilization. This allows Auto Scaling to monitor real-time metrics and trigger scaling actions when thresholds are met. Scheduled tasks, by contrast, are based on specific times rather than performance metrics.

I disagree, I feel like a scheduled task could also work here.

Just creating a scaling configuration isn't enough, right?

Wait, is it really that simple? I thought there was more to it.

I think it's option B too! Makes the most sense.

You definitely need to configure the attributes of the scaling group.

I’m leaning towards creating a scaling configuration, but I also remember something about event-triggered tasks. It’s a bit confusing!

I feel like creating a scheduled task was mentioned in our study materials, but I can't recall how it fits into this specific scenario.

I think we might need to configure the attributes of the scaling group to finalize the scaling rule. It sounds familiar from our practice questions.

I remember something about scaling configurations being essential for Auto Scaling, but I'm not entirely sure if that's the right answer here.

Ah, I see now. The question is asking what I need to do in addition to setting the scaling rule. Based on the options, it looks like I need to create a scheduled task to finish the configuration. I'll make sure to select that choice.

Okay, let me think this through. I need to set the scaling rule to "Remove 1 ECS instance" and then configure something else to complete the setup. I'm guessing it's probably creating an event-triggered task, but I'll double-check the options to be sure.

Hmm, I'm a bit unsure about this one. Do I need to create a scaling configuration first, or can I just jump straight to setting up the scaling group attributes? I want to make sure I don't miss a step.

This seems pretty straightforward. I think the key is to configure the scaling group attributes to trigger the scaling rule based on the CPU utilization threshold.

I agree with Leana, setting up the scaling configuration is the first step in this process.

I think the answer is D. Creating an event-triggered task makes the most sense for setting the scaling rule based on the average CPU utilization rate.
