A switch is configured to be part of a VTP domain so that its VLAN database is not affected by any changes in the domain. Which mode should be configured on this switch?

VTP client mode causes the switch to receive and synchronize its VLAN database with VTP server advertisements, making it directly vulnerable to any domain-wide VLAN changes.

A switch in VTP transparent mode maintains its own independent, locally configured VLAN database and does not adopt VLAN changes advertised by VTP servers in the domain. It ignores received VTP advertisements entirely for its own database, protecting it from unintended additions or deletions caused by domain-wide updates. The switch still forwards VTP frames to neighboring switches, ensuring VTP propagation continues through it without the switch itself being affected.

VTP server mode allows the switch to both originate VLAN changes and synchronize with the domain, meaning its VLAN database is fully governed by VTP domain state.

VTP neutral is not a valid operational mode in Cisco's VTP implementation - the three valid modes are server, client, and transparent.
