Alibaba Cloud CAP-C01 Value Pack (Frequently Bought Together)

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

A pharmaceutical company runs protein folding experiments on-prem. The experiments are split into two parts:
* A simulation application that runs on Linux, and outputs data to an NFS share every minute.
* A visualization application that runs on Windows that converts data from the simulation into graphics.
This application requires an SMB file system.
To support these applications, the company maintains two synchronized file systems, which is prone to data duplication and contributes to inefficient data storage. Lately, they have been considering migrating their use case to Alibaba Cloud. However, they do not want to make any code changes to either application.
As a Cloud Architect, propose a solution for this case.

• A. Migrate both applications to Alibaba Cloud Container Service for Kubernetes. Use Alibaba Cloud File Gateway for storage.
• B. Migrate the simulation application to Linux ECS instances. Migrate the visualization application to Windows ECS instances. Use Alibaba MQ to exchange data between the applications.
• C. Migrate the simulation application to Linux ECS instances. Migrate the visualization application to Windows ECS instances. Use Apsara File Storage NAS for storage.
• D. Migrate both applications to Alibaba Function Compute. Use Object Storage Service (OSS) to exchange data between the applications.

A financial services firm is deploying a real-time analytics platform on Alibaba Cloud to analyze sensitive customer transaction data. The platform must ensure data encryption at rest and in transit, centralized encryption key management, and compliance with internal security policies.
As a Cloud Architect, which Alibaba Cloud services would you recommend for the firm to utilize to meet these requirements? (Correct answers: 3)

• A. Enable Transparent Data Encryption in ApsaraDB RDS for data at rest.
• B. Use SSL/TLS certificates from SSL Certificates Service for encrypting data in transit.
• C. Configure Security Groups to restrict inbound traffic to ECS instances.
• D. Deploy Redis on ECS instances for session management.
• E. Implement Alibaba Cloud Key Management Service (KMS) to manage encryption keys securely.

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

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