The correct answer on here is just Sw1, but you are saying you think it’s both 1 and 2? I do not understand why that’s needed. Creating it on the vtp mode server should propagate the clans to the other switch even if it’s a server also as long as it’s in the same vtp domain.
Yes, it is the same question but I chose SW1 and SW2 because neither one was in the primary server operating mode from the output of the "show vtp status" command. See reason below:
HINT: VTP Operating Mode is set to Primary Server!
A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2.
B. Configure VLAN 500 and VLAN 600 on SW1 only.
C. Configure VLAN 500 and VLAN 600 on SW2 only.
D. Configure VLAN 500 and VLAN 600 on SW1, SW2 and SW4.
E. On SW2, configure vtp mode as off and configure VLAN 500 and VLAN 600, configure back to vtp server mode.
Correct Answer: B
Explanation Explanation/Reference: In VTP version 3, there are two additional fields under the output of “show vtp status” command.
They are: + “Primary ID”: The MAC address of the Primary Server + “Primary Description”: The hostname of the Primary Server.
The Primary Server is used on VTP version 3 to avoid the bad behavior in version 2. In VTP version 2, a VTP client (or Server) can be taken out of the network. When it comes back, it can overwrite a VTP Server if its Revision number is higher. This problem no longer exists in VTP version 3 because there is only one VTP Primary Server at a time. Only a VTP Primary Server can create new VLAN. After creating new VLAN, the VTP Primary Server will advertise its VLAN database to other VTP clients/servers so in fact answer A is not correct.
In this question you just need to check if Sw1 or Sw2 is the VTP Primary Server then we can create both VLAN 500 & 600 on it. Then it will advertise these VLANs to other switches.
