Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 65
Topic #: 3

The backend server pool of an Alibaba Cloud SLB contains multiple ECS instances, which may have different service capacities. To exploit the different service capacities of backend ECS instances, which of the following statements is correct?

AChoose Weighted Round Robin mode to set higher weights to ECS instances with higher capacities The higher the weight of the backend ECS instance the higher chance that the instance will receive requests.

BSLB cannot assign more requests to certain ECS instances.

CChoose Round-Robin model and ECS instances with higher capacities will surely be assigned with more requests.

DChoose Weighted Least-Connection mode, and ECS instances with higher capacities will surely be assigned with more requests.

I bet the backend ECS instances have different RAM sizes. That's gonna be a real 'weight' on your mind when choosing the right load balancing mode!

D seems like the most logical choice. Weighted Least-Connection should be able to distribute the load based on instance capacities.

C is tempting, but I'm not convinced that Round-Robin alone can exploit different capacities. Weighted methods might be better.

But in Weighted Round Robin mode, higher weights are assigned to ECS instances with higher capacities, so they receive more requests.

B seems to contradict the premise of the question. SLB is designed to handle different instance capacities, so it must be able to assign more requests to certain instances.
