A telecommunications company is expanding its backend architecture on Alibaba Cloud to add new services but needs to consolidate security management. They use multiple VPCs and want to streamline authorization management across their services.
What strategy should they adopt to simplify security group management across VPCs?

• A. Deploy network ACLs to manage traffic at the vSwitch level instead.
• B. Develop a centralized logging system for monitoring all security group activities.
• C. Leverage advanced security groups to contain higher IP counts across VPCs.
• D. Use basic security groups to create rules referencing other security groups, simplifying traffic control.

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. Implement ApsaraDB for MongoDB for handling complex queries separately.
• C. Enable read/write splitting in PolarDB to redirect read queries to read-only nodes.
• D. Utilize Elastic Compute Service (ECS) instances for running analytical queries externally.

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 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.
• 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. 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.
• 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.

A company has a data ingestion workflow that consists of:
* An Alibaba Cloud Simple Message Queue topic for notifications about new data deliveries.
* An Alibaba Cloud Function Compute service to process the data and record metadata.
The company observes that the ingestion workflow fails occasionally because of network connectivity issues.
When such a failure occurs, the Function Compute instance does not ingest the corresponding data unless the company manually reruns the job.
Which combination of actions should a solutions architect take to ensure that the Function Compute instance ingests all data in the future? (Correct answers: 2)

• A. Increase the memory allocation for the Function Compute instance.
• B. Deploy the Function Compute instance in multiple Regions.
• C. Modify the Function Compute service to read from the Simple Message Queue queue.
• D. Create a Simple Message Queue queue, and subscribe it to the existing Simple Message Queue topic.
• E. Use Triggers to automatically invoke the Function Compute service.
