QUESTION 95
LAB The information of the question You will configure FastEthernet ports 0/12 through 0/24 for users who belong to VLAN 20. Also, all VLAN and VTP configurations are to be completed in global configuration mode as VLAN database mode is being deprecated by Cisco. You are required to accomplish the following tasks:
1.
Ensure the switch does not participate in VTP but forwards VTP advertisements received on trunk ports.

2.
Ensure all non-trunking interfaces (Fa0/1 to Fa0/24) transition immediately to the forwarding state of Spanning-Tree.

3.
Ensure all FastEthernet interfaces are in a permanent non-trunking mode.

4.
Place FastEthernet interfaces 0/12 through 0/24 in VLAN 20
