Alibaba Cloud Certified Associate (ACA) Practice Test

The primary service offered by Alibaba Cloud's DNS is to manage domain names and resolve DNS queries. DNS, or Domain Name System, is a fundamental component of the internet that translates human-readable domain names, such as www.example.com, into IP addresses that computers use to identify each other on the network.

This service is essential for directing internet traffic efficiently and ensuring that users can access websites using easily memorable domain names instead of lengthy numerical IP addresses. By resolving DNS queries, Alibaba Cloud's DNS facilitates the seamless navigation of users to the correct web resources, thereby playing a crucial role in the functionality of online services.

Enhancing online security, providing cloud storage, and analyzing user traffic are important functions within the realm of cloud computing but do not represent the core purpose of a DNS service. Such features may complement the overall cloud ecosystem but are not central to the fundamental role of managing domain names and processing DNS queries.
