A switch has been configured for three different VLANs: VLAN2, VLAN3, ...
Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication.

Understanding VLANs and Inter-VLAN Routing
When multiple VLANs (Virtual Local Area Networks) exist, they cannot communicate with each other directly. A router is required to facilitate this communication through inter-VLAN routing.
Router and Switch Connection
To connect a router to a switch for VLAN communication, the router needs to have a specific type of interface. Here’s why a fast Ethernet connection (100Mbps) is the best choice:
Bandwidth Requirements
- VLANs often have multiple devices communicating simultaneously; therefore, a higher bandwidth is necessary.
- A 100Mbps Ethernet connection can handle the data transfer between VLANs efficiently compared to lower bandwidth options like 10Mbps Ethernet or 56Kbps Serial.
Single Connection Efficiency
- With only one connection between the router and the switch, it is crucial to maximize this link's capacity.
- A 1Gbps Ethernet (option D) would provide even higher bandwidth, but it is more than necessary for basic VLAN communication and may incur higher costs without much benefit.
Cost-Effectiveness
- 100Mbps Ethernet is widely available and cost-effective, making it a practical choice for inter-VLAN routing without sacrificing performance.
Conclusion
In summary, the best interface for a router connecting to a switch for three VLANs is:
- Option C: 100Mbps Ethernet
This option balances speed, efficiency, and cost, ensuring effective communication between VLANs.
