Alibaba Cloud Certified Associate (ACA) Practice Test

An essential feature of Alibaba Cloud's Database Management Service is its automated maintenance and scaling of databases. This functionality allows users to focus on their applications rather than the underlying database infrastructure management. Automated maintenance helps ensure that databases remain up-to-date, secure, and optimized without requiring manual intervention from the user. Additionally, the ability to automatically scale resources according to demand means that users can efficiently handle varying workloads, providing a more responsive and cost-effective database solution overall. This feature not only enhances usability but also improves performance and resource management for organizations using the service.

Other options do not accurately represent the capabilities of Alibaba Cloud's Database Management Service. For instance, supporting only relational databases would limit its versatility, while being exclusive to on-premises solutions contradicts the cloud-based model. Furthermore, requiring advanced coding knowledge to configure would create unnecessary barriers for users, as the service is designed to be accessible to a broad range of users, including those with limited technical expertise.
