A new switch is added to the network, and several production VLANs are shut down. Which of the following is a probable cause for this scenario? (Choose two.)
A. The new switch has a lower configuration revision number than existing switches.
B. The new switch has a higher configuration revision number than existing switches.
C. The new switch is operating in transparent mode.
D. The new switch is operating in server mode.
Correct Answer: B, D
Explanation:
The VLAN database of the new switch will overwrite the VLAN databases of the production switches because it is operating in server mode and has a higher VLAN configuration revision number. The VLAN Trunking Protocol (VTP) is used to synchronize VLANs between different switches. The VTP configuration revision number is used to determine which VTP switch has the most current version of the VLAN database, and is incremented whenever a VLAN change is made on a VTP server switch.
