Alibaba Cloud Certified Associate – Cloud Computing — Question 19

You are developing a highly available web application using stateless web servers. Which services are suitable for the application? (Choose three.)

Answer options

Correct answer: A, B, C

Explanation

The correct answers are RDS, SLB, and ECS because they provide the necessary features for high availability and scalability. RDS offers managed database services, SLB provides load balancing to distribute traffic, and ECS allows for container orchestration. MaxCompute is focused on big data processing, and OSS is for object storage, which do not directly contribute to the high availability of web applications.
