  • Q1. What is STP full form ?
  • Ans. 

    STP stands for Spanning Tree Protocol.

    • STP is a network protocol used to prevent loops in Ethernet networks.

    • It works by creating a loop-free logical topology by blocking redundant paths.

    • STP elects a root bridge and calculates the shortest path to it for each network segment.

    • It uses Bridge Protocol Data Units (BPDU) to exchange information between switches.

    • STP is defined by the IEEE 802.1D standard.

  • Answered by AI
  • Q2. What is the main function of the Root bridge switch ?
  • Ans. 

    The main function of the Root bridge switch is to control the flow of data traffic in a spanning tree network.

    • The Root bridge switch is elected as the central point of the spanning tree network.

    • It determines the shortest path for data traffic to reach all other switches in the network.

    • The Root bridge switch sends Bridge Protocol Data Units (BPDUs) to other switches to exchange information and maintain the spanning tree...
