Alibaba Cloud CAP-C01 Exam Syllabus Topics:

Alibaba Cloud Certified Professional: Cloud Architect Sample Questions:

Question #1
A company is deploying a mission-critical application on Alibaba Cloud ECS instances that require high availability and failover capabilities. The application must remain accessible even if an entire zone fails.
Which deployment strategy should the company use to ensure high availability?

A. Use a single ECS instance with a high-performance EBS volume.
B. Deploy all ECS instances in a single zone with a backup ECS instance.
C. Deploy ECS instances in multiple regions for redundancy.
D. Distribute ECS instances across multiple zones within a single region.

Question #2
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 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.
B. 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.
C. 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.
D. 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.

Question #3
Keanu uses Elastic Compute Service (ECS) instances to run batch jobs to process data at 00:00 AM and 04:00 AM every day. An Auto Scaling group manages the ECS instances, which run as pay-as-you-go instances. If a batch job fails on one instance, another instance will reprocess the job.
Which of the following solutions provides the MOST cost-effective way to run these jobs?

A. Create a new launch template for the Auto Scaling group. Configure the launch template to use higher specification instances. Set a policy to scale out based on CPU usage.
B. Purchase a 1-year Savings Plan for ECS that covers the instance family of the Auto Scaling group that the batch job uses.
C. Purchase a 1-year reserved instance for ECS that covers the instance family of the Auto Scaling group that the batch job uses.
D. Create a new launch template for the Auto Scaling group. Configure the launch template to use preemptible instances. Set a policy to scale out based on CPU usage.

Question #4
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. Utilize Elastic Compute Service (ECS) instances for running analytical queries externally.
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. Replicate data from PolarDB in real time to MaxCompute with Data Transmission Service (DTS), and perform analytics in MaxCompute.

Question #5
Clarence runs a retail company that hosts an e-commerce website on Alibaba Cloud across multiple Alibaba Cloud regions. Clarence wants the website to be operational at all times to ensure customers can make purchases around the clock. The website stores data in a PolarDB for MySQL instance.
Which of the following solutions will provide the HIGHEST availability for the database?

A. Utilize the Global Database Network (GDN) to establish cross-region clusters for PolarDB, enabling both read and write operations across multiple regions. In case of a failure, seamlessly direct traffic to a secondary region that can serve as the primary node, maintaining high availability and minimal downtime.
B. Deploy the Cluster Edition of PolarDB for MySQL to ensure that the system can elect a new primary node from read-only nodes when the primary node fails. Ensure that the website is configured to reconnect to the cluster after the failover.
C. Configure cross-region backup and restoration in PolarDB. During disruptions, restore the latest backup set to a new PolarDB cluster in another region. Redirect application traffic to this restored cluster and configure read/write splitting for this cluster.
D. Create two PolarDB for MySQL clusters configured with read/write splitting in two different regions.
When a region fails, use Function Compute to replicate the data in the read-only nodes to the healthy region. Then, configure the website to fail over to the healthy region.
