CAP-C01問題集、Alibaba Cloud実際の試験問題

質問 1

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. Migrate the images and files to a File Storage NAS instance that is mounted on every ECS instance.

B. Configure an accelerated IP address in Global Accelerator for the access endpoint.

C. Configure an Alibaba Cloud CDN distribution for the website.

D. Migrate the images and files to an Object Storage Service (OSS) bucket that is mounted via ossfs to every ECS instance.

E. 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.

質問 2

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. Leverage advanced security groups to contain higher IP counts across VPCs.

B. Develop a centralized logging system for monitoring all security group activities.

C. Use basic security groups to create rules referencing other security groups, simplifying traffic control.

D. Deploy network ACLs to manage traffic at the vSwitch level instead.

正解: C

質問 3

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. Utilize SLS for its seamless integration, capturing logs without infrastructure management complexity.

B. Anticipate increased latency in logging due to scaling events and prioritize using dedicated resources.

C. Use Application Real-time Monitoring Service to implement resource monitoring.

D. Presume that real-time log analysis will be limited and avoid real-time analytics.

正解: A

質問 4

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. Deploy Alibaba Cloud Global Accelerator for all inter-region traffic routing.

B. Set up Cloud Enterprise Network (CEN) and integrate with Simple Log Service.

C. Use Alibaba Cloud Express Connect with Transit Router and integrate with Security Center.

D. Implement VPC peering between all regional VPCs and utilize Security Groups for access control.

E. Deploy multiple VPN Gateways in each region and manage connections individually.

正解: B,C

質問 5

Eric is developing a containerized application that will run on an Alibaba Cloud Container Service for Kubernetes (ACK) cluster. This production application will run on a managed ACK cluster that is provisioned with pay-as-you-go instances.
Eric also needs a dedicated ACK cluster for development work. This cluster will be used infrequently to test the resiliency of the application. Due to having a limited workforce and time, Eric hopes that ACK will be able to manage all the nodes in the cluster.
As a Cloud Architect, which of the following solutions will meet these requirements MOST cost-effectively?

A. Create an Auto Scaling group and associate a launch template that uses preemptible instances.
Configure the user data to add these instances to a dedicated ACK cluster.

B. Create a managed ACK cluster and configure the node pool with preemptible instances.

C. Create a managed ACK cluster and configure the node pool with subscription instances.

D. Create two managed ACK clusters and configure one to use a node pool with pay-as-you-go instances, and one to use a node pool with preemptible instances.

正解: D

質問 6

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 Function Compute as functions, and configure a concurrency limit to handle the peak load. Serve the functions over API Gateway.

B. 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.

C. 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.

D. 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.

正解: B
