The answer to this question is A. transparent.

The Virtual LAN Trunking Protocol (VTP) is a Cisco proprietary protocol that enables the sharing of VLAN information across a group of network switches. VTP helps to simplify network administration by allowing the creation, deletion, and renaming of VLANs across multiple switches in a domain simultaneously.

There are three different modes of operation for VTP: server, client, and transparent.

  • Server mode: In this mode, the switch can create, modify, and delete VLANs in the VTP domain. These changes are then propagated to all other switches in the domain. Server mode is the default mode when a switch is first powered on.

  • Client mode: In this mode, the switch cannot create, modify, or delete VLANs in the VTP domain. The switch can receive updates about VLANs from VTP server switches, but it cannot send updates to other switches in the domain.

  • Transparent mode: In this mode, the switch can create, modify, and delete VLANs locally on the switch, but these changes are not propagated to other switches in the VTP domain. The switch will still receive updates from VTP server switches, but it will not forward those updates to other switches in the domain.

Therefore, the VTP mode that allows the Cisco Catalyst switch administrator to make changes to the VLAN configuration that only affect the local switch and are not propagated to other switches in the VTP domain is transparent mode.
