Rate this question:
In the default VTP mode, VLANs can be created and modified on a switch.
Switches in VTP server mode store VLANs in the vlan.dat database.
VTP-enabled switches exchange three types of advertisements: summary routes, subnet advertisements, and advertisement requests from transparent bridges.
The switch configuration must be saved and the switch reloaded to reset a configuration revision number.
VTP updates are exchanged across trunk links only.
Switches in different VTP domains can exchange updates if revision numbers are the same.
Rate this question:

Rate this question:
The other switches in the domain can be running either VTP version 1 or 2.
There is a risk that the switch may cause incorrect VLAN information to be sent through the domain.
VTP will block frame forwarding on at least one redundant trunk port that is configured on this switch.
VLAN configuration changes made on this switch will be sent to other devices in the VTP domain.
This switch will update its VLAN configuration when VLAN changes are made on a VTP server in the same domain.

Any switch port that receives a BPDU will ignore the BPDU message.

Rate this question:
Routers send periodic updates only to neighboring routers.
Routers send triggered updates in response to a change.
Routers create a topology of the network by using information from other routers.

Paths are chosen based on the lowest number of hops to the designated router.
