A company runs its cloud infrastructure on Alibaba Cloud. Jose, a Cloud Architect for the company, needs to define the infrastructure as code. Currently, the infrastructure is deployed in a single Alibaba Cloud region.
The company ' s business expansion plan includes deployments across multiple regions and multiple Alibaba Cloud accounts.
What should Jose do to meet these requirements?

• A. Use Alibaba Cloud Resource Directory. Deploy ROS templates from a management account and leverage Cloud Governance for overseeing deployments across different accounts.
• B. Implement Alibaba Cloud Resource Directory along with ROS Stack Group. Deploy a ROS stack from an account that has the necessary RAM permissions for cross-account management.
• C. Employ nested stacks using ROS templates. Change the region by using nested stacks for different regional deployments.
• D. Utilize ROS templates. Add RAM policies to control access across various accounts. Deploy the ROS templates to multiple regions.

Lucy is a Cloud Architect at a new organization. They are creating a new application for their subscribers, which consists of a single static page and a persistent database layer. Based on the performance of their website, the application will experience traffic from millions of users for 4-6 hours in the morning, but only a few thousand for the rest of the day. Furthermore, the data engineers in the organization have requested that the app support rapid access to the database for their data warehouse requirements.
Which of the following solutions can meet these requirements while providing the MOST scalability?
(Correct answers: 2)

• A. Deploy Cluster Edition PolarDB cluster as the database solution in pay-as-you-go mode.
• B. Host the static assets on a primary Elastic Compute Service (ECS) instance and replicate the instance across multiple regions and zones with Auto Scaling before the morning rush.
• C. Host the static content in an Object Storage Service (OSS) bucket, and configure it as the origin for an Alibaba Cloud CDN distribution.
• D. Deploy a serverless PolarDB cluster as the database solution.

A global telecommunications company hosts its web application on Alibaba ECS instances behind an Alibaba Cloud Application Load Balancer (ALB). The application has static data stored in Object Storage Service (OSS). The company is aiming to enhance performance and reduce latency for both static and dynamic content. The domain name is maintained by Alibaba Cloud DNS.
Which of the following solutions provides the required functionality with the LEAST configurations?

• A. Create an Alibaba Cloud CDN distribution with ALB as an origin and set up Global Accelerator with OSS as an endpoint. Configure DNS for routing.
• B. Configure an Alibaba Cloud CDN distribution with ALB as an origin and set up Global Accelerator with OSS as an endpoint. Use two unique DNS names for routing content independently.
• C. Create an Alibaba Cloud CDN distribution with OSS and ALB as origins. Configure DNS to route traffic to the CDN distribution.
• D. Use an Alibaba Cloud CDN distribution with OSS as an origin, and configure Global Accelerator with ALB and CDN endpoints. Create a custom domain for the application.

Jason ' s company is running a traditional web application on Alibaba Cloud ECS instances. The company wants to improve efficiency by refactoring the application as microservices that run on containers. The application must be deployed across multiple environments: production and testing. Load for the application is variable, but the minimum load and maximum load are known. As a Cloud Architect, you have been assigned the job of designing the updated application with a serverless architecture that minimizes operational complexity.
Which solution will meet these requirements MOST cost-effectively?

• A. Upload the container images to Serverless App Engine (SAE) and create separate environments and deployments for production and testing. Configure an ALB for each of the SAE deployments.
• B. Upload the container images to Function Compute as functions, and configure a concurrency limit to handle the peak load. Serve the functions over API Gateway.
• C. Upload the container images to Alibaba Cloud Container Registry (ACR) and configure two Alibaba Cloud Container Service for Kubernetes (ACK) Managed clusters to manage the expected load. Deploy services from the ACR images, and configure an ALB for each of the ACK Managed clusters.
• D. Upload the container images to Alibaba Cloud Container Registry (ACR) and configure two Alibaba Cloud Container Service for Kubernetes (ACK) Serverless clusters to manage the expected load.
  Deploy services from the ACR images, and configure an ALB for each of the ACK Serverless clusters.

Yolanda works for a software company that serves customers all around the globe. They want to ensure that all communications between users and the application are encrypted. They also want to automate the deployment of SSL/TLS certificates across multiple backend servers to streamline operations and maintain high security standards.
Which combination of Alibaba Cloud services should the company implement to achieve this goal MOST effectively? (Correct answers: 2)

• A. Alibaba Cloud CDN with HTTPS enabled
• B. Key Management Service (KMS)
• C. Web Application Firewall (WAF)
• D. Server Load Balancer (SLB) with SSL offloading
• E. Certificate Management Service
