Which of the following cannot exist in a single Dataverse environment?

In a single Dataverse environment, a single Dataverse database can exist alongside Power Apps applications and Power Automate flows. However, an environment can only host one instance of a Dataverse database at a time. This is a fundamental design of Dataverse, as it consolidates data management and ensures that applications and flows leverage a unified data source.

The concept behind this design is to maintain consistency and integrity of data. Allowing multiple instances of databases within the same environment could lead to complexity and potential data conflicts. Each Dataverse environment is structured to support a single database, which simplifies administration and enhances performance by keeping the connections and data access streamlined.

Power Apps apps and Power Automate flows are intended to interact with this single database, allowing for effective application development and automation solutions. While environments can be created to host multiple databases, each specific environment is limited to one instance to prevent complications and to optimize functionality.
