What is one possible outcome if inter-VLAN routing is misconfigured?

• A. Devices in different VLANs can communicate
• B. Devices in the same VLAN cannot communicate
• C. Broadcasts may not be sent
• D. Switchports may revert to default settings

Answer: (B)

When inter-VLAN routing is misconfigured, a likely outcome is that devices within the same VLAN may be unable to communicate with each other. This situation typically arises from incorrect settings in the VLAN configurations or issues with the routing protocols that are necessary for inter-VLAN communication. VLANs are designed to segment network traffic, allowing devices in the same VLAN to communicate directly while preventing communication with devices in different VLANs unless properly routed. In an ideal configuration, devices in the same VLAN share the same broadcast domain and can communicate without restrictions. However, misconfigurations can lead to VLANs being isolated from each other. This can manifest as a lack of connectivity for devices that are supposed to interact within the same VLAN, potentially causing disruptions in network functionality and user experience. Understanding VLAN configurations and inter-VLAN routing is essential, as these elements work together to facilitate proper communication and ensure that data is efficiently routed across the network.
