Does a VTP server maintain its VLAN database in NVRAM?

• A. Yes
• B. No
• C. Only during active mode
• D. Depends on switch settings

Answer: (A)

A VTP (VLAN Trunking Protocol) server does indeed maintain its VLAN database in NVRAM (Non-Volatile Random Access Memory). This is significant because NVRAM retains data even when the device is powered off, ensuring that the VLAN configuration is preserved across reboots. When a switch is configured as a VTP server, it not only creates and modifies VLANs, but it also advertises these changes to all other switches in the VTP domain. Having the VLAN database in NVRAM allows the switch to store configurations reliably and ensures that all the VLAN settings that have been created or modified by the VTP server are available immediately upon startup. This is crucial for maintaining network continuity and consistency across switches in the same VTP domain, as it allows any switch in that domain to access accurate VLAN information right away after a reboot. Using NVRAM for this purpose differentiates VTP servers from other operation modes that might not necessarily maintain their VLAN information in non-volatile memory, leading to potential loss of configuration upon a restart.
