A user builds an ECS + SLB + RDS architecture on Alibaba Cloud, with Auto Scaling to dynamically manage ECS instances. For business needs, they use ApsaraDB for Redis as a cache for hot data, requiring ECS instances to be added or removed from the Redis whitelist as they scale. As an Alibaba Cloud architect, which three Auto Scaling and OOS features would you recommend to automate adding and removing instances from the Redis whitelist? (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.

If users use Alibaba Cloud Anti-DDoS Basic service, when the attack traffic exceeds the service upper limit, the black hole policy will then be triggered; after that, the users’ servers can still provide services at a limited speed.
