After explaining the difference between the models, she asks if you can
provide her with examples as to when each model would be appropriate.
Give at least one example for each of the two models.

When the networking infrastructure has an extensive amount of intranet usages. Physical modeling enables you to produce models that can be easily
reused and shared with other engineers. Importing data and models from
other environments helps ensure the accuracy of your models. By
integrating those models with control and signal processing algorithms,
you can test for integration errors early in the design process.
