Which VLAN can NOT be filtered through the VLAN Trunking Protocol (VTP) Pruning feature of Cisco switches?
- VLAN 1
- VLAN 10
- VLAN 100
- VLAN 1000
VLAN 1 traffic cannot be pruned. Cisco recommends that VLAN 1 be used for management of VLANs.
VTP pruning is a Cisco VTP feature that allows switches to dynamically delete or add VLANs to a trunk for traffic transmission. It creates an efficient switching network by optimal use of available trunk bandwidth.
The options 10, 100, and 1000 are incorrect because these VLAN numbers can be pruned. By default, VLANs 2 to 1000 are eligible for pruning.
