Company F launched a new App and put the installation package (size: 6 MB) on its official website (hosted on Elastic Compute Service (ECS)). Initially, the download speed was acceptable. However, due to an advertising event on CCTV last week, the number of installation package downloads drastically increased, resulting in poor user experience and a significant increase in ECS bandwidth cost.

Company F can select Alibaba Cloud ______________ service to solve download speed and bandwidth cost problems at the same time.

  1. Object Storage Service (OSS) + Content Delivery Network (CDN)
  2. Object Storage Service (OSS) + Auto Scaling
  3. Object Storage Service (OSS) + ApsaraDB for RDS
  4. Auto Scaling + Elastic Compute Service (ECS) instance

Answer(s): A

Explanation:

To handle high download traffic efficiently, Company F can use Object Storage Service (OSS) to store the installation package and Content Delivery Network (CDN) to distribute it. OSS provides scalable, low-cost storage, while CDN caches content at edge nodes, reducing the load on the ECS instance and improving download speeds for users. This combination helps control bandwidth costs on ECS and provides faster download speeds by serving content closer to end-users.

Alibaba Cloud OSS and CDN Integration



Company G developed a shopping App. The system is built using Alibaba Cloud products, including ECS instances and OSS in the North China 1 region, where static web pages and images are stored on OSS.

After the App went online, the access speed in mainland China was acceptable. Recently, the company decided to expand to the U.S. market and requires acceptable access speeds for U.S. users.

To address this requirement, Company G should select Alibaba Cloud _______________ service.

  1. Enabling Object Storage Service (OSS) + Content Delivery Network (CDN) in East China 1 and North China 2 regions
  2. Enabling Object Storage Service (OSS) + Content Delivery Network (CDN) in West US (Silicon Valley) region
  3. Enabling Auto Scaling and more Elastic Compute Service (ECS) instances
  4. Enabling Auto Scaling and Content Delivery Network (CDN)

Answer(s): B

Explanation:

To improve access speeds for U.S. users, Company G can enable OSS with CDN in the West US (Silicon Valley) region. By deploying CDN in a region close to the target audience, the static content stored in OSS can be cached and delivered more efficiently. CDN caches the content at edge locations, reducing latency for users in different geographical areas. This approach is ideal for expanding the application to international markets while maintaining fast access times.

The effect of CDN is highly related to the scenario in which it is used. _______________________ is not an applicable scenario to use CDN.

  1. Personal netdisk service having low repeated access rate
  2. Pure static enterprise website
  3. Short video delivery website
  4. Application download site

Answer(s): A

Explanation:

CDN is most effective for scenarios with high repetitive access, where content is frequently requested and can be cached, such as static websites, video delivery, and application download sites. In contrast, a personal netdisk service typically involves unique, private files with low repeat access rates, making CDN less effective since the content is unlikely to be accessed by multiple users frequently, thus reducing the benefit of caching.

Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies. To ensure ECS instances created by Auto Scaling can correctly respond to user requests without additional configuration, applications deployed on these ECS instances must be _______________.

  1. Stateless and horizontally scalable
  2. Stateful
  3. Stateless and idempotent
  4. All data is locally stored on ECS instance disks

Answer(s): A

Explanation:

Applications deployed on ECS instances that are managed by Auto Scaling should be stateless and horizontally scalable. Stateless applications do not store session data or any critical information on a single instance, allowing them to be replicated or terminated without affecting the application's overall functionality. Horizontal scalability ensures that more instances can handle additional traffic as demand increases. This setup allows Auto Scaling to add or remove instances seamlessly without requiring reconfiguration.
