Which of the following is NOT a feature of RouterOS?

RouterOS includes a wide range of features that cater to various networking needs, such as dynamic routing, VPN support, and the ability to perform both wired and wireless routing. However, when considering the specific functions and capabilities of RouterOS, intrusion detection is not a built-in feature of the operating system. While RouterOS can certainly be used in environments where intrusion detection systems or services may be implemented, it does not provide native intrusion detection capabilities as part of its feature set.

This distinction highlights the network management and traffic routing functionalities that RouterOS excels in, while also making clear that it lacks dedicated tools for monitoring and detecting unauthorized access or anomalies typical of intrusion detection systems. As such, the other options represent functionalities that are integral to RouterOS, confirming that intrusion detection stands out as not being a feature of RouterOS.
