What role does trunking play in VLAN technology?

• A. It slows down network speed
• B. It merges multiple VLANs into a single network
• C. It allows for the transmission of multiple VLAN traffic over a single link
• D. It isolates traffic to prevent interference

Answer: (C)

Trunking is a vital concept in VLAN (Virtual Local Area Network) technology, allowing for efficient use of network resources. The correct answer highlights that trunking enables the transmission of multiple VLAN traffic over a single link. This is accomplished through the configuration of trunk ports on network devices, which can encapsulate and identify frames from different VLANs using protocols like IEEE 802.1Q. By using trunking, network administrators can reduce the number of physical connections required between switches and other devices while still maintaining the ability for those devices to communicate across various VLANs. This capability is essential for optimizing bandwidth and simplifying network designs, especially in larger networks where numerous VLANs are in play. In essence, trunking allows for enhanced scalability and flexibility within a network, facilitating the seamless flow of data for multiple VLANs simultaneously over a single connection, rather than needing separate links for each VLAN. This consolidation helps to manage network complexity and improve overall performance.
