When are scenarios assumed to be shared in resource definitions?

Scenarios are assumed to be shared in resource definitions when they meet specific upgrade conditions. This is crucial because it means that the scenarios have been validated and are configured to function properly within the broader resource framework. Sharing scenarios ensures that the resources can be effectively utilized across different instances or applications, facilitating collaboration and consistency in how they are employed.

By meeting these specific upgrade conditions, the scenarios are essentially vetted to maintain compatibility and functionality during various stages of the resource lifecycle. This ensures that when multiple users or systems access these resources, they can operate with the same level of efficiency and without conflicts, thereby streamlining workflows and enhancing productivity across teams.

In contrast, the other options pertain to contextual factors that do not inherently determine whether scenarios are shared. User-defined properties might personalize settings but do not dictate sharing mechanisms. Similarly, being linked to external resources does not guarantee shared usage; the external linkage might simply represent a dependency. Lastly, having a global scope typically refers to the accessibility of a scenario rather than its sharing status among different systems or teams.
