Suggested Answer: C 🗳️
To create private VLANs, you will need to only disable pruning on the switch that contains the private VLANs. In this case, only SW4 will connect to servers in a private VLAN.

To configure private VLAN we have to change VTP (even version 3) to Transparent mode. Infact, to disable VTP pruning on Sw4 (in Client mode) we also have to change to VTP Transparent mode so answer C can be understood as “change SW4 to Transparent mode” so itis the best choice.

I think correct answer is A. We know that SW1 and SW2 are in server mode, SW4 - in client mode. SW1 is primary server. We can not create VLANs on switch in client mode at all, but only on primary server. When I attempt create private vlans in my lab on primary server I received: %Private VLANs can only be configured when VTP is in transparent/off modes in VTP version 1 or 2 and in server/transparent/off modes in VTP version 3 when pruning is turned off So we must configure private vlans on SW1 previosly disabling pruning on it.
