Alibaba Cloud Certified Associate – Cloud Computing — Question 32

A large shopping mall deploys a new video surveillance system. The five-floor building in which the mall is located 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 rapidly and the engineers find that 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.

Answer options

• A. Container Service
• B. ECS
• C. OSS
• D. CDN

Correct answer: C

Explanation

The correct answer is OSS (Object Storage Service), which is designed for scalable storage and can handle large amounts of data, making it ideal for video storage needs. ECS, while used for hosting, does not provide the same scalability for storage, and Container Service and CDN do not directly address the storage issue at hand.
