Cisco 200-125 Exam
Which protocol supports sharing the VLAN configuration between two or more switches?
- A. multicast
- B. STP
- C. VTP
- D. split-horizon
Answer: Option C.
“VTP allows a network manager to configure a switch so that it will propagate VLAN configurations to other switches in the network”
VTP minimizes misconfigurations and configuration inconsistencies that can cause problems, such as duplicate VLAN names or incorrect VLAN-type specifications. VTP helps you simplify management of the VLAN database across multiple switches. VTP is a Cisco-proprietary protocol and is available on most of the Cisco switches.
