An e-commerce company needs to execute a daily scheduled job to aggregate and filter sales records stored in an Alibaba Cloud OSS bucket. Each object can be up to 10 GB in size. The task may take up to an hour to run with pre-determined CPU and memory requirements. The goal is to reduce operational management efforts.
Identify an appropriate architecture using Alibaba Cloud services to perform the scheduled job efficiently.

• A. Configure Serverless Workflow to execute server-side processing directly on OSS data with Function Compute.
• B. Set up an ACK cluster with ECS (Elastic Compute Service) instances, managed through Auto Scaling and scheduled tasks using Serverless Workflow.
• C. Deploy a Container Service for Kubernetes (ACK) cluster with Elastic Container Instance (ECI) as the launch type. Use EventBridge to schedule the job.
• D. Use Function Compute with EventBridge to run a scheduled trigger daily.

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

A media company is developing a video processing pipeline utilizing Alibaba Cloud Container Service for Kubernetes (ACK). They want to use a serverless approach to accommodate unpredictable workloads but are unsure about its impact on logging.
What considerations should the company keep in mind regarding logging in a serverless ACK environment?

• A. Anticipate increased latency in logging due to scaling events and prioritize using dedicated resources.
• B. Presume that real-time log analysis will be limited and avoid real-time analytics.
• C. Utilize SLS for its seamless integration, capturing logs without infrastructure management complexity.
• D. Use Application Real-time Monitoring Service to implement resource monitoring.

A global hotel chain is migrating its reservation system to Alibaba Cloud. The system must provide high availability across multiple regions, ensure data consistency, and support real-time updates to prevent double bookings. Additionally, the system should integrate with third-party payment gateways securely.
Which combination of Alibaba Cloud services should the hotel chain implement to architect this reservation system effectively? (Correct answers: 3)

• A. Set up Object Storage Service (OSS) for storing reservation logs with versioning enabled.
• B. Utilize Function Compute for processing payment gateway integrations.
• C. Use PolarDB with Global Database for real-time data replication and consistency.
• D. Deploy ECS instances in multiple regions with Application Load Balancer (ALB) for traffic distribution.

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. Employ nested stacks using ROS templates. Change the region by using nested stacks for different regional deployments.
• B. Utilize ROS templates. Add RAM policies to control access across various accounts. Deploy the ROS templates to multiple regions.
• C. Use Alibaba Cloud Resource Directory. Deploy ROS templates from a management account and leverage Cloud Governance for overseeing deployments across different accounts.
• D. 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.
