CompTIA Network+ N10-009 Practice Question

Creating a separate VLAN for personal devices used at work is the most effective method for network segregation in this scenario. This setup segregates the network traffic of personal devices from the core corporate network, thereby minimizing the risk of a security breach into sensitive business resources. Guest networks, while also providing segregation, are more appropriate for temporary visitors rather than employees who need more consistent network access. Disabling unused ports enhances overall network security but does not contribute directly to the segregation of personal devices. Implementing time-based authentication adds a security layer but doesn't segregate network traffic.
