Alibaba Exam ACP-Cloud1 Topic 4 Question 84 Discussion

Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 84
Topic #: 4

A challenging thing in the gaming industry is the unpredictable and fluctuating business traffic. For example, 1 ECS instance is enough to meet all business demands today; however, we may need 10 ECS instances tomorrow.

In this situation, it is difficult to predict the number of ECS instances required. If we use too few ECS instances, we may not be able to cope with business peaks; whereas if we use too many ECS instances, we may introduce unnecessary costs.

On Alibaba Cloud, _______________ is the best product portfolio to cope with the gaming scenario described above.

AServer Load Balancer (SLB) + Elastic Compute Service (ECS) + ApsaraDB for RDS + Auto Scaling

BServer Load Balancer (SLB) + Elastic Compute Service (ECS) + ApsaraDB for RDS

CElastic Compute Service (ECS) + Auto Scaling

DElastic Compute Service (ECS)

Show Suggested Answer

Suggested Answer: A

In this scenario, a combination of Server Load Balancer (SLB), ECS, ApsaraDB for RDS, and Auto Scaling is ideal. SLB distributes incoming traffic across multiple ECS instances, ensuring high availability and reliability. Auto Scaling automatically adjusts the number of ECS instances based on demand, managing costs efficiently by scaling out during peak times and scaling in when demand decreases. ApsaraDB for RDS provides a managed database service that handles increasing database demands without requiring complex manual scaling. This portfolio is optimal for fluctuating gaming traffic as it ensures load balancing, scalability, and cost control.
