The ACA Database Certification validates your ability to design, deploy, and manage database solutions on Alibaba Cloud. The ACA Database Exam tests both theoretical knowledge and practical decision-making across modern database architectures. This page guides you through the exam syllabus, question formats, and a structured study plan to help you prepare efficiently and confidently.

ACA-Database Exam Syllabus & Core Topics

Use this topic map to guide your study for Alibaba ACA-Database (ACA Database Exam) within the ACA Database Certification path.

  • Database Overview: Understand core database concepts, Alibaba Cloud database services, and how to select the right database type for specific workloads.
  • Relational Database: Design schemas, optimize queries, configure replication and high availability, and troubleshoot performance issues in traditional SQL databases.
  • NoSQL: Work with key-value stores, document databases, and time-series data; understand consistency models and scaling strategies.
  • Data Warehouse: Build analytical solutions, optimize columnar storage, design fact and dimension tables, and execute complex aggregation queries.
  • Database Ecological Tools: Integrate backup, migration, monitoring, and ETL tools; manage data pipelines and ensure data quality.
  • Database Common Solution: Apply best practices for multi-region deployment, disaster recovery, cost optimization, and compliance in production environments.

Question Formats & What They Test

The ACA Database Exam combines multiple-choice items with scenario-based questions to assess both foundational knowledge and real-world problem-solving ability.

  • Multiple Choice: Core definitions, service features, configuration options, and key terminology across all six topic areas.
  • Scenario-Based Items: Analyze real-world cases, such as choosing a database type for a high-traffic application, designing a disaster recovery plan, or troubleshooting a replication lag, and select the best technical decision.
  • Configuration & Best Practice: Determine optimal settings for backup windows, read replicas, indexing strategies, and security policies based on given constraints.

Questions progress in difficulty and emphasize practical application over memorization, reflecting how database decisions are made in production environments.

Preparation Guidance

An effective study routine maps each topic to dedicated time blocks, allowing you to build depth progressively. Focus on understanding the "why" behind each concept and how topics connect across deployment, monitoring, and optimization workflows.

  • Allocate one week per topic: Database Overview, Relational Database, NoSQL, Data Warehouse, Database Ecological Tools, and Database Common Solution. Track completion and revisit weak areas.
  • Practice question sets after each topic; review explanations to understand why correct answers are right and others are wrong.
  • Link concepts across use cases: for example, how schema design in Relational Database affects query performance, and how Data Warehouse principles apply to large-scale analytics.
  • Complete a timed practice test in the final week to build pacing confidence and identify remaining gaps.
  • Review high-weight topics (typically Relational Database, NoSQL, and Database Common Solution) in your final three days.

Frequently Asked Questions

Which topics carry the most weight on the ACA Database Exam?

Relational Database, NoSQL, and Database Common Solution typically account for the largest portion of exam questions. However, all six topics are important; focus on mastering Relational Database and NoSQL fundamentals first, then deepen your knowledge of real-world deployment and troubleshooting scenarios covered in Database Common Solution.

How do Database Overview, Relational Database, NoSQL, Data Warehouse, Database Ecological Tools, and Database Common Solution connect in real projects?

In a typical production workflow, Database Overview informs your initial service selection, Relational Database and NoSQL handle transactional or analytical data storage, Data Warehouse aggregates insights, Database Ecological Tools manage backups and migrations, and Database Common Solution ensures high availability and compliance. Understanding these connections helps you design end-to-end solutions rather than memorizing isolated facts.

How much hands-on experience should I have before taking the ACA Database Exam?

Ideally, you should have deployed at least one database service on Alibaba Cloud and performed basic operations like creating instances, configuring backups, and monitoring performance. If you lack hands-on experience, prioritize Alibaba Cloud free tier labs for Relational Database and NoSQL to build familiarity with the console and common workflows.

What are the most common mistakes that cause lost points on the exam?

Candidates often confuse when to use Relational Database versus NoSQL, overlook disaster recovery requirements in scenario questions, and misunderstand consistency and availability trade-offs in distributed systems. Read scenario questions carefully, identify the business constraint (cost, latency, consistency), and eliminate options that don't address that constraint.

What is an effective review strategy for the final week before the exam?

Spend the first three days reviewing high-weight topics and redoing practice questions you missed. In days four and five, take a full-length timed practice test and review every explanation, even for correct answers. In the final two days, skim your notes on Database Ecological Tools and Database Common Solution, and do a quick mental walkthrough of three to four complex scenarios to reinforce your decision-making process.

Question No. 1

Which of the following architectures are supported by ApsaraDB for Redis Enhanced Edition (Tair)? (Number of correct answers: 3)

Show Answer Hide Answer
Correct Answer: A, B, C

Question No. 2

You can purchase more read-only nodes after you have created a cluster. If the primary node fails, the system automatically promotes the read-only node with the highest failover priority to become the new primary node while restoring the faulty node.

Show Answer Hide Answer
Correct Answer: A

Each node in a PolarDB cluster has a failover priority. The system performs the following steps to automatically elect a primary node:

Find all the read-only nodes that can be elected as the primary node.

Select one or more read-only nodes that have the highest failover priority.

If the failover to the first node fails due to reasons, such as network issues and abnormal replication status, the system tries to switch to another node until the failover succeeds.
