Alibaba Cloud Certified Associate – Cloud Computing — Question 24

www.company.com is a newly launched social portal for exchanging automotive information. The portal is based on PHP, including 10GB of images, and some
JavaScripts files. Currently one single ECS instance is used to host all the application content as well as a MySQL database. With the growing number of users, the portal is getting slower to load images or respond to user requests. Moreover, there will be additional 50GB image content uploaded to the portal every week.
Which combination of Alibaba Cloud services below can help resolve the storage and performance issue at the same time?

Answer options

• A. OSS + CDN combination
• B. OSS + MTS combination
• C. OSS + RDS combination
• D. OSS + ECS combination

Correct answer: A

Explanation

The correct answer is A, as using OSS (Object Storage Service) in combination with a CDN (Content Delivery Network) will enhance the storage capacity and significantly improve the loading speed of images by distributing content globally. The other options do not adequately address both the storage requirements and the performance issues: MTS focuses on media processing, RDS is for database services, and ECS alone does not solve the storage problem.
