The CCNA Routing and Switching are considered to be an excellent starting point for your IT career. The CCNA R&S is extraordinarily popular among the IT Candidates, which would be learned and highly sought after by the IT industry. This certification is going to validate your ability for installing, configuring, operating, and troubleshooting medium-size routed and switched networks. Typically, the CCNA R&S is going to qualify you for roles including network technician, systems administrator, network engineer, and more. Before we discuss some interview question and answers, if you are searching for a good training institute, you should check out the courses offered by the SPOTO. Q 1) What is Networking? Ans: Networking is going to be utilized to connect or operate with a network. It is the process of using and creating wired or wireless networks for exchanging information, ideas, files, and other electronic communication. Q 2) What does Protocol mean? Ans: Protocol is defined as the rules that connect two or more than two devices to transfer the information from one device to another. It would also help you to know how data is being transferred from one network to another network for communication. Q 3) What is the OSI reference model? Ans: OSI is a reference model which would be telling you about how information and data are going to communicate over a network. It would consider being a conceptual framework that understands the relationships of transmission. Q 4) What are the different layers of the OSI model? Ans: Basically, there are 7 types of layers of OSI model, offered by the SPOTO. Each of the layers has its own functionality in the OSI model. They would be considered as:
  •    Layer 1 – Physical
  •    Layer 2 – Data Link Layer
  •    Layer 3 – Network
  •    Layer 4 – Transport
  •    Layer 5 – Session
  •    Layer 6 – Presentation
  •    Layer 7- Application
Q 5) What is a Switch and why are we using Switches? Ans: Switch is considered to be used in order to receive the signal for creating a frame. It would be forwarding the packets between various LAN segments. It supports the packet control when the data is sent to the Network layer or Data Link layer of the OSI model. While sending packets, a signal would get enabled and gets accessed by reading the destination that would be addressing and forwards the frame to the appropriate frame, hence we use switches. Q 6) What are Routers? Ans: Routing is the process of finding the path on which the data or information that could pass from the source to its destination. The apparatus by which routing is done is called Routers. Q 7) Mention the difference between Switch, Routers, and Hub. Ans: Switch: A Switch is used for receiving the signal in order to create a frame. It forwards the packets between various segments of LAN. It is the platform for packet control when the data is sent at a Network layer or Data Link layer of the OSI model. It is going to support a single broadcast domain and multiple collision domains. Routers: The router is a networking gateway device which would be used to forward data packets to the computer networks. A router is connected by at least a single LAN along with its IP address or with WAN or LAN. A router supports about two broadcasting domains. Hub: In the hub, if anything achieves in its port then it sends it out to the others. It is the least complicated and less expensive. It has a single collision domain as well as a single broadcast domain. If you want to gain more interview question, you should check out the study materials given by the SPOTO.
