Which tool simulates network types and technologies for analyzing the impacts on end-to-end behaviors?

Riverbed Modeler is the correct tool for simulating network types and technologies to analyze their impacts on end-to-end behaviors. It provides a comprehensive platform for modeling and understanding how different components of a network interact with each other and how various technologies affect overall network performance. By using Riverbed Modeler, professionals can visualize and test various scenarios in a virtual environment, allowing for in-depth analysis and predictive insights before actual deployment or changes to a network.

This simulation is particularly valuable in the context of digital forensics and network analysis, as it helps in understanding the potential impacts of network configurations, traffic patterns, and technology changes on data flows and system behaviors.

The other tools mentioned have their specific uses; for example, GNS3 is primarily focused on network device virtualization, while Cisco Packet Tracer is designed primarily for educational purposes and basic network simulations. Although these tools are beneficial for other types of network simulations and training, Riverbed Modeler's advanced capabilities for realistic modeling of network behavior make it the most suitable choice for analyzing end-to-end impacts.
