Does a VTPv1/v2 client maintain its VLAN database in NVRAM?

A VTPv1 or VTPv2 client does not maintain its VLAN database in NVRAM, which is why the answer is accurate. In VTP (VLAN Trunking Protocol), the client mode is designed to receive VLAN information from a VTP server. While a VTP client can temporarily hold VLAN information in RAM for operational purposes, it does not save this information permanently. As a result, when the switch is reloaded or powered off, the VLAN information is lost, and the switch must rely on the VTP advertisements from the server to repopulate its VLAN database upon reconnection to the network.

This transient storage in RAM is crucial for VTP clients, as they become dependent on VTP messages from servers to learn about VLANs instead of creating their own. The other options do not apply because a VTPv1/v2 client does not utilize NVRAM for storing its VLAN database, nor does the behavior change based on configuration, as it is inherent to how VTP clients operate.
