NEW QUESTION # 44
A company has 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?
- A. Event-based scaling should not be triggered at the 2,000-user frequency.
- B. Event-based scaling does not take resource load into account.
- C. Event-based scaling should not track user subscriptions.
- D. Event-based scaling does not scale down resources.
Answer: B
Explanation:
Event-based scaling triggers based on specific events, such as the number of user subscriptions in this case. It does not necessarily account for the actual load or utilization of compute resources. This is why the platform's resources continue to scale up even though compute utilization is low; the scaling decision is being made based on the number of subscribed users rather than the current resource usage.
