Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 18

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)

ACloud 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

BScheduled 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.

CManual 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.

DHealthy check mode: Ensures that all the current ECS instances in scaling groups are working correctly to meet user access requests.
