Alibaba ACP-Cloud1 Exam - Topic 3 Question 65 Discussion

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?
A) Choose 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.
B) SLB cannot assign more requests to certain ECS instances.
C) Choose Round-Robin model and ECS instances with higher capacities will surely be assigned with more requests.
D) Choose Weighted Least-Connection mode, and ECS instances with higher capacities will surely be assigned with more requests.

Weighted Round Robin is the best option for utilizing capacity effectively.

I disagree, B is misleading. SLB can assign requests based on weights.

Weighted Least-Connection sounds familiar, but I'm not confident it guarantees more requests for higher capacity instances.

I practiced a similar question, and I think Round Robin just distributes requests evenly, regardless of capacity.

I feel pretty confident that Option A is the correct answer here. Weighted Round Robin is designed to send more traffic to the higher capacity instances, so that's the best way to exploit the different service capacities in this scenario.

Hmm, I'm a bit confused. I'm not sure if SLB can actually assign more requests to certain instances based on their capacities. Option B seems to suggest that's not possible, so I'm not sure which answer is correct.

I think the key here is to exploit the different service capacities of the backend ECS instances. Option A sounds like the right approach, using Weighted Round Robin to assign more requests to the higher capacity instances.

Okay, let me think this through. I know Round-Robin mode distributes requests evenly, so that doesn't sound like the right approach if we want to take advantage of the different capacities. Option D with Weighted Least-Connection seems more promising, but I'm not 100% sure.

Okay, I remember learning about this in class. The two options are BYOL, where you bring your own Oracle license, and License Included, where Amazon provides the license. I'm confident that B is the correct answer.

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!

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.
