What VTP modes allow you to manually add or remove VLANs in VTP version-3?

In VTP (VLAN Trunking Protocol) version 3, the VTP modes that allow for manual addition or removal of VLANs are the VTP Transparent mode and the VTP Primary Server mode. The VTP Primary Server mode is specifically designed to handle VLAN database information within a network and allows network administrators to make VLAN changes. When in VTP Primary Server mode, administrators can create, modify, and delete VLANs, which reflects the versatility and control it provides over the VLAN configuration.

On the other hand, the VTP Transparent mode allows a switch to pass VTP advertisements through the network without participating in VLAN management. This mode does not process VTP messages but allows manual VLAN configuration on the switch. Therefore, being in Transparent mode means VLANs can still be locally managed without being impacted by VTP advertisements from other switches.

VTP Client mode restricts VLAN configuration changes, as it only accepts and implements VTP messages received from VTP Servers and does not allow any local VLAN configuration to occur. VTP Secondary Server does exist in VTPv3 to help with redundancy and processing of VLANs, but it does not have the same capabilities as the Primary Server for adding or removing VLANs.

Thus, the answer
