A fintech startup is building a transaction monitoring application using Alibaba Cloud Container Service for Kubernetes (ACK). They are debating between adopting a dedicated cluster setup versus a serverless architecture to ensure scalability and cost efficiency.
What factors should they consider to decide between a serverless or a dedicated ACK deployment? (Correct answers: 2)

• A. ACK Serverless is ideal if they expect highly fluctuating traffic and prefer paying only for resources used.
• B. A dedicated ACK cluster ensures lower latency as compared to a serverless setup due to exclusive resource allocation.
• C. ACK Serverless offers better integration with Alibaba Cloud ' s network services.
• D. A dedicated ACK cluster is better suited if they need precise control over the infrastructure and networking configuration.

A pharmaceutical company runs protein folding experiments on-prem. The experiments are split into two parts:
* A simulation application that runs on Linux, and outputs data to an NFS share every minute.
* A visualization application that runs on Windows that converts data from the simulation into graphics.
This application requires an SMB file system.
To support these applications, the company maintains two synchronized file systems, which is prone to data duplication and contributes to inefficient data storage. Lately, they have been considering migrating their use case to Alibaba Cloud. However, they do not want to make any code changes to either application.
As a Cloud Architect, propose a solution for this case.

• A. Migrate the simulation application to Linux ECS instances. Migrate the visualization application to Windows ECS instances. Use Alibaba MQ to exchange data between the applications.
• B. Migrate both applications to Alibaba Function Compute. Use Object Storage Service (OSS) to exchange data between the applications.
• C. Migrate both applications to Alibaba Cloud Container Service for Kubernetes. Use Alibaba Cloud File Gateway for storage.
• D. Migrate the simulation application to Linux ECS instances. Migrate the visualization application to Windows ECS instances. Use Apsara File Storage NAS for storage.

Clarence runs a technology services company that uses ApsaraDB RDS. The company wants to streamline their database management and set up a robust access control structure.
Which of the following solutions provides the required functionality with the LEAST operational overhead?

• A. Use the permission management feature of Data Management Service (DMS) to control and audit user access to databases.
• B. Set up a WAF instance in front of the database to block SQL injection attempts and ensure the security of the data.
• C. Use RAM policies to restrict access to databases and implement ActionTrail to audit actions performed on the database.
• D. Implement access control via IP whitelist to control who has access to the database.

A worldwide retail company is adapting their e-commerce platform to handle spikes in online traffic during annual sales events. They are using Alibaba Cloud services and need a solution that can automatically scale resources to maintain performance during these peaks.
What solutions should the company implement to efficiently manage their resources during high-traffic periods? (Correct answers: 3)

• A. Set up Application Load Balancer (ALB) to distribute incoming traffic evenly across resources.
• B. Deploy Auto Scaling to automatically scale ECS instances horizontally based on traffic.
• C. Implement Function Compute to handle additional processing demands dynamically.
• D. Host static images and videos on Object Storage Service (OSS) and configure acceleration with Alibaba Cloud CDN.

Clash for Victory is a popular online game that is hosted on Alibaba Cloud. As latency can have a huge impact on gameplay, the developers for the game want to implement a mechanism to route all requests to the closest access point, monitor the health of the game, and redirect traffic to healthy backend servers.
The game is deployed in multiple regions on Elastic Compute Service (ECS) instances that are part of Auto Scaling groups configured behind Application Load Balancers (ALBs).
As a Cloud Architect, what course of action would you take?

• A. Create Alibaba Cloud CDN distribution and specify Object Storage Service (OSS) as the origin server.Configure the cache behavior to use origin cache headers.
• B. Create an Alibaba Cloud CDN distribution and specify the ALB as the origin server. Configure the cache behavior to use origin cache headers. Use Function Compute to optimize the traffic.
• C. Configure an ApsaraDB RDS database to serve as the data store for the application. Create a Tair (Redis OSS-Compatible) cluster to act as the in-memory cache for hosting the application data.
• D. Configure a Global Accelerator instance. In each region, add a listener for the port that the game listens on, and attach it to the endpoint group of that region. Add the ALB instances as the endpoint.
