Q3. STP loop prevention how its working
Ans. 
STP loop prevention is achieved by blocking redundant paths in a network to prevent loops.
• STP (Spanning Tree Protocol) identifies redundant paths in a network

• STP selects a root bridge to be the central point of the network

• STP blocks certain ports to prevent loops while still allowing for redundancy

• If a link fails, STP will unblock a previously blocked port to maintain connectivity
