Availability Zones refer to data centers in the same region with independent power grids and networks. Which of the following statements are true for Zones? (Choose three.)

A large shopping mall deploys a new video surveillance system. The five-floor building in which the mall is located has installed 35 HD cameras to monitor the major exits. The surveillance system is deployed on an ECS instance, which has four 2 TB data disks to store video data.

However, video data grows so rapidly that the engineers find the ECS will run out of storage space within 2 weeks.

In this case, ___________ product is thought to be the best solution for addressing the storage challenge while ensuring quick access to historical video data when needed.

During a scaling activity, when Auto Scaling fails to add ECS instances into a scaling group, it will try to ensure transaction completeness and roll back the scaling activity.

For example, a scaling activity intends to create and add 20 ECS instances into the scaling group, but only 19 of them are added successfully. In this case, the entire scaling activity will be rolled back, and the 19 instances will be removed and released as well.
