How to Configure STP & PVST

How to Configure STP & PVST - Lab
Configuration to be done.

Create VLAN 10,20,30 and 40 on all switches.
Who is the root bridge for VLAN 10 and why?
Make Switch-1 is the root bridge for VLAN 10, switch Switch-2 should be the backup in case switch Switch-1 fails. You are not allowed to use the priority command.
Make Switch-2 is the root bridge for VLAN 20, switch Switch-1 should be the backup in case switch Switch-2 fails. You are not allowed to use the priority command.
Make Switch-3 is the root bridge for VLAN 30, switch Switch-4 should be the backup in case switch Switch-3 fails. You are not allowed to use the spanning-tree root command.
Make Switch-4 is the root bridge for VLAN 40, switch Switch-3 should be the backup in case switch Switch-3 fails. You are not allowed to use the spanning-tree root command.
Make sure Switch-4 does not use Fast-Ethernet 1/1 to reach the root bridge in VLAN 10, you are not allowed to shutdown the interfaces.
Make sure Switch-4 uses Fast-Ethernet 1/1 to reach the root bridge in VLAN 20.
Add another Interface between Switch-1 and Switch-3
Make sure Switch-3 uses Fast-Ethernet 1/2 to reach the root bridge of VLAN 10. Dont change the COST value of an interface.
If a host is connected to the Switch-4’s Fast-Ethernet f1/15 interface in future. Make sure it does not send and BPDU's and goes to forwarding mode immediately.
