Alibaba Exam ACA-Cloud1 Topic 6 Question 67 Discussion

Actual exam question for Alibaba's ACA-Cloud1 exam

Question #: 67
Topic #: 6

A video streaming company uses SLB to distribute user requests to 30 ECS instances (the 30 ECS instances have the same configuration). Yet, the company finds that the service traffic soars dramatically every night from 20:00 to 02:00. According to their calculation, the evening traffic is 100% higher than the traffic in other periods of time. To properly respond to user requests, which of the following methods is most preferred from the perspective of cost and implementation simplicity?

AConfigure Auto Scaling appropriately to automatically add or reduce ECS instances.

BManually create 30 ECS instances using the custom image, and then add them to SLB every night before 20:00 and remove them after 02:00.

CCreate 30 ECS instances based on the custom image and add them to SLB. Then, configure weights for these ECS instances to respond to user requests every night from 20:00 to 02:00, and reset those weights to zero for other periods of time.

DConfigure Auto Scaling appropriately to automatically upgrade/downgrade the ECS instances.

Hah, the company should just install a giant hamster wheel to power the servers during the traffic spike. That's the cost-effective solution right there!

Upgrading and downgrading instances? Isn't that just a fancy way of saying Auto Scaling? I think that's the way to go.

Configuring weights to handle the traffic spike? That's a clever idea, but it might be more complex to implement than just scaling up and down.

I see your point, Audrie. However, I think option D could also work well if properly configured. It offers scalability without the manual intervention.

But wouldn't manually creating instances every night be too time-consuming? Auto Scaling in option A seems more automated.

Manually adding and removing instances every night? That sounds like a lot of work. I'd go with the Auto Scaling option for sure.

Option A seems the most straightforward and cost-effective approach. Auto Scaling can automatically adjust the number of instances to handle the traffic surge without manual intervention.
