Basic Networking Interview Questions and Answers
- What is a Link?
A link refers to the connectivity between two devices. It includes the type of cables and protocols used for one device to communicate with the other.
- What are the layers of the OSI reference model?
The OSI (Open Systems Interconnection) reference model consists of seven layers:
- Physical Layer
- Data Link Layer
- Network Layer
- Transport Layer
- Session Layer
- Presentation Layer
- Application Layer
- What is a backbone network?
A backbone network is a centralized infrastructure designed to distribute routes and data to various networks. It handles bandwidth management and multiple channels.
- What is a LAN?
LAN stands for Local Area Network. It refers to the connection between computers and other network devices within a small physical location, such as an office or a building.
- What is a node?
A node is a point or joint where a connection takes place. It can be a computer or device that is part of a network. At least two nodes are required to form a network connection.
- What are routers?
Routers are intelligent network devices that connect two or more network segments. They store information in routing tables, such as paths, hops, and bottlenecks, to determine the best path for data transfer. Routers operate at the OSI Network Layer.
- What is a point-to-point link?
A point-to-point link is a direct connection between two computers on a network, without the need for any other network devices. It involves connecting a cable to the NIC (Network Interface Card) cards of both computers.
- What is anonymous FTP?
Anonymous FTP (File Transfer Protocol) is a way of granting user access to files on public servers without requiring identification. Users log in as anonymous guests.
- What is a subnet mask?
A subnet mask is combined with an IP address to identify two parts: the extended network address and the host address. Like an IP address, a subnet mask is made up of 32 bits.
- What is the maximum length allowed for a UTP cable?
A single segment of an Unshielded Twisted Pair (UTP) cable has an allowable length of 90 to 100 meters. This limitation can be overcome by using repeaters and switches.
- What is data encapsulation?
Data encapsulation is the process of breaking down information into smaller, manageable chunks before it is transmitted across the network. During this process, source and destination addresses, along with parity checks, are attached to the headers.
- Describe Network Topology.
Network topology refers to the layout of a computer network, showing how devices and cables are physically arranged and connected.
- What is a VPN?
VPN stands for Virtual Private Network, a technology that allows a secure tunnel to be created across a network such as the Internet. VPNs enable you to establish a secure dial-up connection to a remote server.
- Briefly describe NAT.
NAT (Network Address Translation) is a protocol that provides a way for multiple computers on a common network to share a single connection to the Internet.
- What is the job of the Network Layer under the OSI reference model?
The Network Layer is responsible for data routing, packet switching, and control of network congestion. Routers operate at this layer.
- How does network topology affect your decision to set up a network?
Network topology dictates the media you
