The correct answer is D. Event-based scaling does not take resource load into account. Event-based scaling triggers resource adjustments based on predefined events rather than actual compute utilization or system load. In this case, the system is scaling up every time 2,000 new users subscribe, regardless of whether the underlying compute resources are actually…
Question
A company developed an online trading platform. The engineering team selected event-based scaling for the platform’s underlying resources. The platform resources scale up with every 2,000 subscribed users. The engineering team finds out that although compute utilization is low scaling is still occurring. Which of the following statements best explains why this is the case?
Options
- AEvent-based scaling does not scale down resources.
- BEvent-based scaling should not be triggered at the 2,000-user frequency.
- CEvent-based scaling should not track user subscriptions.
- DEvent-based scaling does not take resource load into account.

Explanation
Event-based scaling triggers resource adjustments based on predefined events rather than actual compute utilization or system load. In this case, the system is scaling up every time 2,000 new users subscribe, regardless of whether the underlying compute resources are actually under stress. This can lead to unnecessary scaling, increasing costs without improving To optimize scaling, the engineering team should consider a hybrid approach that combines event-based triggers with resource utilization metrics (e.g., CPU, memory, or network load) to prevent over-provisioning.
