What happens if the VTP domain name does not match on two connected switches?

When the VTP (VLAN Trunking Protocol) domain name does not match on two connected switches, they will not exchange VTP information. This is because VTP operates within a specific domain to manage VLAN information and the propagation of that data. For switches to share VTP updates such as adding, deleting, or modifying VLANs, they must belong to the same VTP domain. If the domain names differ, the switches cannot recognize that they are part of the same management framework, leading them to operate independently when it comes to VLAN management.

Establishing a trunk between the switches is still possible even with differing VTP domain names, but without a matching domain, there will be no exchange of VTP information. This means that while the physical connection is established for VLAN tagging, they will each manage their VLANs without any synchronization, which could lead to inconsistencies in VLAN memberships across the switches.

In summary, the correct answer highlights the significance of matching VTP domain names for the exchange of VLAN information, which is a crucial aspect of managing VLANs in a network environment effectively.
