In VLANs (Virtual LANs), what protocol is used to carry VLAN information between switches?

VTP is a Cisco proprietary protocol designed to manage and propagate VLAN configurations across a network of interconnected switches. It ensures consistency by enabling the configuration of VLANs from a central switch, which then distributes the information to other switches within the same VTP domain. VTP reduces administrative overhead, especially in large networks, by centralizing VLAN management. However, it is important to carefully manage VTP configurations, as errors can propagate across the network, causing issues. ________________________________________ Why Other Options Are Incorrect? 1. STP: Prevents loops in Layer 2 networks but does not carry VLAN information. 2. ARP: Resolves IP addresses to MAC addresses and is unrelated to VLANs. 3. IGMP: Manages multicast group memberships, not VLAN configurations. 4. SNMP: Used for network monitoring and management, not VLAN propagation.
