Kimiko works for a multinational retail chain that has just extended its internal business management services to Alibaba Cloud. They want to ensure the security and high-speed connectivity between its on-premises data center and multiple VPCs across different regions on Alibaba Cloud. The company wants to minimize network latency and ensure high availability without managing individual VPN connections for each VPC.
Which Alibaba Cloud service should the company use to achieve this goal?

• A. Alibaba Cloud NAT Gateway
• B. Alibaba Cloud Express Connect with Transit Router
• C. Apsara Stack (private cloud deployment)
• D. Alibaba Cloud VPN Gateway

Camila has set up a simple blog hosted on a single Elastic Compute Service (ECS) instance, storing images and files on an Elastic Block Storage (EBS) disk within the ECS instance, and relying on an ApsaraDB RDS for MySQL instance for its data tier. Camila wants to scale up her blog and enhance both resilience and performance with minimal changes to the application.
As a Cloud Architect, which combination of actions can you take to improve both resilience and performance of the website? (Correct answers: 3)

• A. Take a snapshot of the current ECS instance and create a custom image. Use the image to provision a new ECS instance, and add both the original and new instances to a scaling group. Set up an Application Load Balancer (ALB) in front of the scaling group, and configure the scaling group to maintain a minimum of two ECS instances.
• B. Configure an Alibaba Cloud CDN distribution for the website.
• C. Migrate the images and files to a File Storage NAS instance that is mounted on every ECS instance.
• D. Configure an accelerated IP address in Global Accelerator for the access endpoint.
• E. Migrate the images and files to an Object Storage Service (OSS) bucket that is mounted via ossfs to every ECS instance.

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 a serverless PolarDB cluster as the database solution.
• B. Host the static content in an Object Storage Service (OSS) bucket, and configure it as the origin for an Alibaba Cloud CDN distribution.
• C. Deploy Cluster Edition PolarDB cluster as the database solution in pay-as-you-go mode.
• D. 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.

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. 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.
• C. 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.
• 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 multinational corporation is designing its network architecture on Alibaba Cloud to support its distributed applications. Their requirements include:
* Private and high-speed connectivity between on-premises data centers and Alibaba Cloud VPCs across multiple regions.
* Centralized management and enforcement of network security policies.
* Comprehensive monitoring and logging of all network traffic for compliance and auditing purposes.
Which combination of Alibaba Cloud services should the corporation implement to meet these requirements MOST effectively? (Correct answers: 2)

• A. Implement VPC peering between all regional VPCs and utilize Security Groups for access control.
• B. Deploy Alibaba Cloud Global Accelerator for all inter-region traffic routing.
• C. Set up Cloud Enterprise Network (CEN) and integrate with Simple Log Service.
• D. Use Alibaba Cloud Express Connect with Transit Router and integrate with Security Center.
• E. Deploy multiple VPN Gateways in each region and manage connections individually.
