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. 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.
• B. Create Alibaba Cloud CDN distribution and specify Object Storage Service (OSS) as the origin server.Configure the cache behavior to use origin cache headers.
• C. 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.
• D. 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.

A company is designing an application. The application uses a Function Compute function to receive information through API Gateway and to store the information in an ApsaraDB RDS for PostgreSQL database.
During the proof-of-concept stage, the company noticed that the volume and velocity of data is very high, and they had to increase the Function Compute quotas significantly. Even with the increased quotas, they would sometimes lose data. The company has hired Javert, a Cloud Architect, to recommend a new design to improve scalability and minimize the configuration effort.
Which of the following solutions will meet these requirements?

• A. Set up two Function Compute functions. Configure one function to receive the information. Configure the other function to load the information into the database. Integrate the Function Compute functions by using ApsaraMQ for Kafka.
• B. Refactor the Function Compute function code to Apache Tomcat code that runs on Elastic Compute Service (ECS) instances. Connect the database by using native Java Database Connectivity (JDBC) drivers.
• C. Set up two Function Compute functions. Configure one function to receive the information. Configure the other function to load the information into the database. Integrate the Function Compute functions by using a Simple Message Queue publish model.
• D. Switch from ApsaraDB RDS to Alibaba Cloud Tablestore, using hot data caching with Tablestore SDK to handle access.

An online education company plans to migrate their services to Alibaba Cloud. They want to improve their video streaming quality during peak hours using Alibaba Cloud services. As a Cloud Architect, you are tasked with building a solution to manage traffic spikes without compromising on video quality.
What combination of services would BEST fit their requirements? (Correct answers: 3)

• A. Use Alibaba Cloud Global Accelerator for optimizing cross-region traffic paths.
• B. Create Alibaba Cloud CDN distributions to cache video content at PoPs close to the audience.
• C. Employ Auto Scaling to adjust server capacity dynamically based on user traffic.
• D. Implement Tair (Redis OSS-Compatible) to reduce latency during user authentication.

A healthcare organization is deploying its patient management system on Alibaba Cloud. They require:
* Secure, private connectivity between their on-premises servers and Alibaba Cloud VPCs.
* Automated failover to ensure connectivity during outages.
* Scalable bandwidth to handle varying data loads without manual intervention.
Which Alibaba Cloud service should the organization implement to meet these requirements?

• A. Express Connect with Redundant Connections
• B. VPN Gateway
• C. VPC peering between VPCs
• D. NAT Gateway

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