Alibaba Cloud Certified Associate – Cloud Computing — Question 15

A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group. He/she sets the `Minimum number of instances` to 6 and `Maximum number of instances` to 8.
After correctly configuring scaling settings, the customer adds a scaling rule `Adjust to 10 ECS instances`, and creates a scheduled task based on this rule.
And then, the customer checks the scaling group and see it already contains 6 valid ECS instances, he/she then enables this scaling group immediately.
How many ECS instances are left in the scaling group when the scheduled task is activated once?

Answer options

• A. Eight
• B. Ten
• C. Six
• D. Five

Correct answer: A

Explanation

The correct answer is A, as the scaling rule to adjust to 10 ECS instances will bring the total to 8, which is within the maximum limit set for the scaling group. The group currently has 6 instances, and upon execution of the scheduled task, it will scale up to 8 instances, leaving no additional instances created beyond this limit. Options B, C, and D are incorrect because they either exceed the maximum limit or do not reflect the adjustment made by the scaling rule.
