What is the primary advantage of VLAN Trunking?

1. It requires specialized hardware

2. It allows unlimited virtual network connections

3. It simplifies network security

4. It increases the physical cabling requirements

The correct answer is: It allows unlimited virtual network connections

The primary advantage of VLAN Trunking is that it allows multiple VLANs to be carried over a single physical link between network devices, which effectively facilitates unlimited virtual network connections. This capability is important in a networking environment because it helps to optimize the use of existing network infrastructure, reducing the need for additional physical cabling. With VLAN Trunking, different VLANs can share the same switch port, allowing for better bandwidth use and more efficient network resource management. VLAN Trunking enhances network flexibility by enabling traffic from multiple VLANs to pass through a single connection, which is especially useful in large networks where segmenting traffic into various VLANs can help with organization and performance. This means that the organization can maintain numerous logical networks on fewer physical connections, effectively managing the complexity of the network architecture while promoting scalability. Other options touch on aspects that are not advantages of VLAN Trunking. For instance, specialized hardware isn't a direct benefit of VLAN Trunking itself, but rather a necessity for supporting such configurations. Network security can be simplified through proper VLAN configurations, but that isn't the primary advantage of trunking itself. Additionally, while it may require careful cabling considerations, VLAN Trunking ultimately reduces the cabling requirements by allowing multiple connections
