The mode that can only accept and relay VLAN information without creating or modifying VLANs is VTP Client. In VTP (VLAN Trunking Protocol) Client mode, a switch listens for VTP advertisements from VTP Servers and uses the received VLAN information to configure its local VLAN database but does not have the capability to create, delete, or modify VLANs locally. This means that while it can participate in VTP by propagating VLAN information throughout the network, it relies entirely on VTP Servers for any VLAN changes, maintaining a strict dependency and ensuring consistency in VLAN configurations.

In contrast, VTP Server mode allows for the creation, modification, and deletion of VLANs, making it a more flexible but also more vulnerable mode, as errors can propagate if incorrect changes are made. VTP Transparent mode does not participate in the VTP domain, meaning it can create VLANs locally but does not share that information, thus not adhering to the shared VLAN information protocol. VTP Off mode simply disables VTP on the switch, leading to no VLAN information exchange at all. Therefore, VTP Client is the only mode that strictly receives and relays VLAN information without any modifications.
