Eric is developing a containerized application that will run on an Alibaba Cloud Container Service for Kubernetes (ACK) cluster. This production application will run on a managed ACK cluster that is provisioned with pay-as-you-go instances.
Eric also needs a dedicated ACK cluster for development work. This cluster will be used infrequently to test the resiliency of the application. Due to having a limited workforce and time, Eric hopes that ACK will be able to manage all the nodes in the cluster.
As a Cloud Architect, which of the following solutions will meet these requirements MOST cost-effectively?

• A. Create a managed ACK cluster and configure the node pool with preemptible instances.
• B. Create two managed ACK clusters and configure one to use a node pool with pay-as-you-go instances, and one to use a node pool with preemptible instances.
• C. Create a managed ACK cluster and configure the node pool with subscription instances.
• D. Create an Auto Scaling group and associate a launch template that uses preemptible instances.
  Configure the user data to add these instances to a dedicated ACK cluster.

A global consultancy firm needs to ensure that their applications hosted on Alibaba Cloud have low latency for users distributed worldwide. They require a solution that can cache static content and dynamically route user requests to the nearest point-of-presence (PoP).
Which Alibaba Cloud service should the firm implement to achieve this?

• A. Global Traffic Manager (GTM)
• B. Alibaba Cloud CDN
• C. Server Load Balancer (SLB)
• D. Express Connect

Muthu is a Cloud Architect who is designing the architecture of a new application being deployed to Alibaba Cloud. The application will run on Elastic Compute Service (ECS) pay-as-you-go instances and will automatically scale across multiple zones based on load. The ECS cluster will scale in and out frequently throughout the day. An Application Load Balancer (ALB) will handle the load distribution. The architecture needs to support distributed session data management.
What should Muthu do to ensure that the architecture supports distributed session data management?

• A. Use STS (Security Token Service) for managing sessions.
• B. Use Tair (Redis OSS-Compatible) to manage and store session data.
• C. Use CloudMonitor to manage sessions.
• D. Use session stickiness of the SLB to manage session data.

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

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 the permission management feature of Data Management Service (DMS) to control and audit user access to databases.
• 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 RAM policies to restrict access to databases and implement ActionTrail to audit actions performed on the database.
