The switch sends and receives data frames.
A network administrator wants to add a new switch to existing VTP domain. The new switch will have a VLAN that the administrator does not want other switches displayed. All other VLANs should be visible on all switches and all the VLAN must be visible to the switch again. What solution fulfills the requirements with the least administrative effort?
Add the switch in client mode. After existing VLANs have propagated, change the switch to transparent mode. Add the private VLAN.
