Which VTP mode can be used to pass VLAN information without participating in VLAN creation or deletion?

The VTP mode that allows a switch to pass VLAN information without participating in the creation or deletion of VLANs is the Transparent mode.

In Transparent mode, a switch will communicate VLAN information it receives from other VTP-enabled switches, effectively forwarding this information to devices on the network. However, it does not process or store any VLAN configurations that it receives—they are simply passed along. This means that a switch operating in Transparent mode can maintain its local VLAN database and can create, modify, and delete VLANs, but these local changes do not affect the VTP domain since the switch itself does not participate in VTP.

This mode is particularly useful in scenarios where you want a switch to relay VLAN information without allowing it to affect or control VLAN management, providing flexibility in larger networks that require specific VLAN arrangements.

In contrast, the other VTP modes either involve active participation in VLAN management (such as Server mode, where VLANs can be created or deleted and those changes are propagated to other switches) or have restrictions that do not allow VLAN information to be forwarded further (like Client mode, where switches can only receive VLAN information and cannot make changes). Hybrid is not a recognized VTP mode specific to Cisco.
