Alibaba ACP-Cloud1 Exam - Topic 4 Question 89 Discussion

Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 89
Topic #: 4

You have set an alert policy for the disk usage of an ECS instance by using Alibaba Cloud CloudMonitor. Each measurement cycle lasts for 5 minutes, during which the average disk usage is measured. If the average disk usage exceeds 80% for five consecutive measurement cycles, an alert will be reported. After your average disk usage exceeds 80%, how long will it take to receive an alert?

A0 minutes

B30 minutes

C40 minutes

D20 minutes

Show Suggested Answer

Suggested Answer: B

With a measurement cycle of 5 minutes and a requirement for five consecutive cycles where disk usage exceeds 80%, it would take 55=255 times 5 = 2555=25 minutes for CloudMonitor to confirm the condition. After confirmation, CloudMonitor typically processes and sends the alert, which may take an additional 5 minutes, totaling approximately 30 minutes before you receive the alert.

No way, it’s 20 minutes. You get the alert right after the last cycle.

But isn’t it 40 minutes? You need time for the alert to trigger.

Yeah, I agree. 5 cycles means 25 minutes, plus the alert time.

I think it’s 30 minutes. Five cycles of 5 minutes each.

I bet the developers who wrote this question were disk-ussing it over a cup of coffee. (Pun intended)

D) 20 minutes seems like the right answer. Why would it take 40 minutes? That's way too long.

I think the answer is B) 30 minutes. It's 5 cycles of 5 minutes, so that's 25 minutes, and then the alert is reported.

The correct answer is C) 40 minutes. It takes 5 consecutive measurement cycles of 5 minutes each, so that's 25 minutes.

I practiced a similar question, and I think the alert would come after 40 minutes since we need to account for the initial exceedance too.

I'm not entirely sure, but I remember something about needing to wait for the cycles to complete before the alert goes off.

If each cycle is 5 minutes and we need five consecutive cycles, that sounds like 25 minutes to me, but I could be wrong.

Hmm, I'm going with C) 40 minutes. It makes sense that it would take 5 cycles of 5 minutes each to trigger the alert.

I think the alert triggers after five cycles, so that would be 25 minutes total, right?

Ah, I see now. The question is asking how long it takes to receive the alert, not how long the average disk usage has to exceed 80%. The answer is definitely B) 30 minutes.

I've got it! The alert is triggered after the average disk usage exceeds 80% for 5 consecutive 5-minute cycles. That means the total time is 25 minutes. The answer must be B) 30 minutes.

I'm a bit confused. Does the question mean the average disk usage has to exceed 80% for the entire 25 minutes, or just for the last 5 minutes of that period?

Okay, let me think this through. Each cycle is 5 minutes, and the alert is triggered after 5 consecutive cycles. So the total time must be 25 minutes, right?
