How can users access Document Understanding (DU) services in the cloud?

The correct choice indicates that users can access Document Understanding (DU) services in the cloud through public Software as a Service (SaaS) endpoints hosted by UiPath. This approach leverages the advantages of cloud technology, including scalability, reliability, and accessibility. By utilizing public SaaS endpoints, users can integrate DU capabilities without the need for extensive infrastructure investments or complex setups, streamlining their access to advanced AI-driven document processing features.

The other options imply methods that deviate from the cloud-based access model. For instance, using dedicated server infrastructure or setting up local servers involves significant setup and maintenance, which contrasts sharply with the efficiency and convenience of a cloud solution. Similarly, restricting access to only private cloud environments would limit the flexibility and ease of use that the public SaaS model offers, making it less advantageous for users looking for scalable solutions.
