Question
A customer purchased the auto scaling service. When the customer enabled the scaling policy for the created scaling group, he found that not only one scaling policy could be enabled for the scaling group, but also multiple scaling policies could be enabled. When enabling multiple scaling policies, it is necessary to ensure that the conditions of the multiple scaling policies do not conflict.

Explanation
Option A is correct because most auto scaling services do allow multiple scaling policies to be active simultaneously on a single scaling group - for example, you might have one policy that scales out based on CPU usage and another that scales in during scheduled off-peak hours. The critical constraint is that these policies must not conflict with each other, meaning they should not trigger contradictory actions (such as one policy scaling up while another simultaneously scales down under the same conditions), as this would create unpredictable behavior. Option B is incorrect because it falsely implies that only one scaling policy can be enabled at a time, which would be overly restrictive and impractical for real-world workloads that require layered scaling strategies. Memory tip: Think of multiple scaling policies like traffic rules - a city can have rules for rush hour AND rules for weekends, as long as those rules do not contradict each other at the same time and place.
