Exam 300-115 topic 4 question 49 discussion

Yes it is correct. VTP primary server: only the primary server is able to create / modify / delete VLANs. This is a great change as you can no longer “accidently” wipe all VLANs like you could with VTP version 1 or 2. •Extended VLANs: you can now synchronize VLANs in the extended VLAN range (1006 – 4094). •Private VLANs: if you have VLANs that are configured as private VLANs then you can synchronize them with VTPv3. •RSPAN VLANs: remote SPAN VLANs can now be synchronized. •MST Support: one of the problems of MST is that you had to configure each switch manually. With VTPv3, MST configurations are synchronized. •Authentication improvements: VTPv3 has more secure methods for authentication. •VTP mode off: If you didn’t want to use VTP for version 1 or 2 then you had to use the transparent mode. VTPv3 can be disabled globally or per interface. •Compatibility: VTP version 3 is compatible with version 2, not version 1.

In addition, only one server per domain can be prompted to be a primary server. client and secondary server devices receive a configuration from a primary server. A secondary server stores the received configuration in a local permanent storage space (for example, NVRAM) and updates other devices in the same domain and for the same instance. In the case of VTP version 1 or VTP version 2, a server can be manually configured via command-line interface (CLI) or Simple Network Management Protocol (SNMP). In VTP version 3, a secondary server cannot be configured manually but can receive updates, similar to a device owning the client role. https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-6500-series-switches/solution_guide_c78_508010.html

can anyone verify this is correct ?
