What is the main function of VLAN Trunking Protocol (VTP)?

• A. To assign IP addresses dynamically
• B. To manage VLAN configuration across multiple switches
• C. To segment traffic based on MAC addresses
• D. To establish a secure connection between routers

Answer: (B)

The main function of VLAN Trunking Protocol (VTP) is to manage VLAN configuration across multiple switches. VTP facilitates the administration of VLANs within a network, allowing for a centralized management system where VLAN information can be propagated throughout an entire network of interconnected switches. This means that when a VLAN is created, deleted, or modified on one switch, VTP ensures that these changes are communicated to all other switches that are part of the same VTP domain. This capability reduces the complexity of managing VLANs in environments where there are many switches, enabling network administrators to maintain a cohesive VLAN architecture without needing to configure each switch individually. VTP also helps to prevent inconsistencies and reduces configuration errors that could arise from manual updates across numerous switches. The other options do not align with VTP's purpose. For instance, assigning IP addresses dynamically relates to protocols like DHCP, while segmenting traffic based on MAC addresses refers to the fundamental operation of switches themselves. Establishing a secure connection between routers pertains to routing protocols and security measures like IPsec, which are outside VTP's function.
