Which statement regarding simulations is true?

The statement regarding simulations that is true is that a simulation with status 'Resolved-Completed' can be re-executed. When a simulation reaches this status, it indicates that the simulation has run to its conclusion and the results are available for review. However, it does not imply that the simulation cannot be run again; rather, it can be re-executed with or without modifications to the input data, parameters, or rules used in the simulation.

This flexibility allows for iterative testing and fine-tuning of decision-making strategies based on previous outcomes. Re-executing a completed simulation can help in assessing how changes in variables may affect the results, thus providing valuable insights for decision improvement.

Other options present limitations or stipulations that do not reflect the true capabilities of simulation execution. The nuances of simulation statuses and the methods used to analyze them are pivotal for effective decisioning in Pega systems.
