iLuZia Lab Interview Questions and Answers

The statement is incorrect. Routers route between different networks, while switches connect devices within the same network.

• Routers route traffic between different networks based on IP addresses

• Switches connect devices within the same network based on MAC addresses

• Example: A router connects a home network to the internet, while a switch connects devices within the home network

Public IP is the address assigned to a device connected to a network, accessible over the internet. Private IP is used within a private network.

• Public IP is unique and globally routable

• Private IP is used within a local network and not accessible over the internet

• Public IP allows devices to communicate with other devices on the internet

• Private IP allows devices to communicate within the local network

• Example of public IP: 203.0.113.1

• Example of private IP: 192.168.0.1

STP stands for Spanning Tree Protocol, a network protocol used to prevent loops in Ethernet networks.

• STP is used to create a loop-free logical topology in a network.

• It works by selecting a root bridge and calculating the shortest path to reach each network segment.

• STP uses a tree-like structure to block redundant paths and ensure data flows efficiently.

• It helps in preventing broadcast storms and improving network stability.

• STP is defined by the IEEE 802.1D standard.

Routers connect multiple networks together, while switches connect devices within a single network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.

• Routers determine the best path for data packets to reach their destination, while switches simply forward data to the appropriate devi...read more

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.

• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how different networking protocols work together.

• Each layer has a specific function and communicates with the layers above and below it.

• Examples of layers include physical layer, data link layer, network layer, transport layer, session layer, presenta...read more
