Kenneth plans to deploy a real-time data processing platform on Alibaba Cloud to support his company ' s Internet-of-Things (IoT) business. The platform will handle millions of sensor data points collected from smart devices globally. Kenneth needs to ensure high throughput and low latency for data ingestion and analysis.
Which solutions should Kenneth consider integrating into the platform architecture to meet his expected performance requirements? (Correct answers: 3)

• A. Deploy Function Compute to process data in real time as it arrives.
• B. Implement Alibaba Cloud Elastic MapReduce (EMR) for batch processing of large datasets.
• C. Use ApsaraMQ for Kafka for high-throughput data streaming.
• D. Store time-series data in Alibaba Cloud ' s Time Series Database.

A retail chain is utilizing Alibaba Cloud ' s PolarDB to manage its inventory and sales databases. They need to ensure that their SQL queries have minimal impact on their production workload while enabling data analysts to run complex analytical queries.
How can the retail chain optimize their database operations for both transactional and analytical workloads?
(Correct answers: 2)

• A. Replicate data from PolarDB in real time to MaxCompute with Data Transmission Service (DTS), and perform analytics in MaxCompute.
• B. Enable read/write splitting in PolarDB to redirect read queries to read-only nodes.
• C. Utilize Elastic Compute Service (ECS) instances for running analytical queries externally.
• D. Implement ApsaraDB for MongoDB for handling complex queries separately.

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. 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. 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.

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

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. A dedicated ACK cluster is better suited if they need precise control over the infrastructure and networking configuration.
• 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. ACK Serverless is ideal if they expect highly fluctuating traffic and prefer paying only for resources used.
