Alibaba ACP-Cloud1 Exam - Topic 7 Question 18 Discussion

A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience). Thus, you use Auto Scaling to elastically adjust computing resources. Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely. In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)
B) Scheduled task: Increases the number of ECS instances to 40 on the first day of the holidays and reduce the number to 20 after the holidays. and C) Manual mode: Set the minimum number of instances to 40 on the first day of the holidays and change the number to 20 after the holidays.
A) Cloud monitor and event-triggered task: Dynamically adds ECS instances during resource shortage and reduces ECS instances during idle hours by monitoring the CPU utilization rate and workload
D) Healthy check mode: Ensures that all the current ECS instances in scaling groups are working correctly to meet user access requests.

Wait, can we really predict traffic that accurately? Sounds too good to be true!

Hmm, I'm a bit confused. I know switches forward frames, but I'm not sure about the technical term for that specific process. I'll have to think this through carefully.

Okay, I think I've got this. Address summarization allows you to represent a block of routes with a single, more general route. This reduces the number of individual entries in the routing table, which in turn reduces the overall table size. The key is that summarization aggregates routes.

This seems like a straightforward question about Azure Storage tiers. I'm pretty confident I can evaluate the bold text and select the correct answer.

at first, I tried the A, but finally, I agreed with BC.. according to this sentence "Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely"
