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.

In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)

A. 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.

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

C. 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. 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.
