Types of Networking Interview Questions

Interviewers want to see whether you can easily communicate technical requirements. They will test the technical knowledge necessary to get the job done. So, there were two types of networking interview questions, which are

• Networking interview questions for freshers
• Networking interview questions for experienced

Networking Interview Questions for Freshers

There are some networking interview questions with answers for freshers.

What is the Network?

A network comprises two or more computers linked to share resources, exchange files, or allow electronic communications. The computers on a network may be connected along cables, telephone lines, radio waves, satellites, or infrared light beams.

How many types of networks, and what are they?

There are four types of networks, and they are

• PAN
• WAN
• LAN
• MAN

What are PAN and LAN?

• PAN

It is a coordination of personal technology devices to communicate over a short distance, less than 33 feet or 10 meters, or within a person’s range, typically using wireless technology.

• LAN

LAN stands for local area network. A network is a category of two or more connected computers, and a LAN is a network contained within a small geographic area, usually within the same building. Home WiFi networks and small business networks are typical examples of LANs. A local area network consists of a series of computers linked to form a network in a circumscribed location.

What are WAN and MAN?

• WAN

A wide-area network is a technology that links offices, data centers, and cloud storage. It is a wide-area network since it spans beyond a single building to include multiple locations spread across a specific geographic area or even the world.

• MAN

 A metropolitan area network is a computer web connecting computers within a metro area, which could be a single large city, multiple cities, towns, or any given ample space with numerous buildings. A MAN is more significant than a LAN but smaller than a WAN.

Definition of Network Topology.

Network topology is the physical and logical organization of nodes and connections in a web. Networking Interview Questions, Nodes usually include switches, routers, and software with switch and router features. Network topologies often act as a graph.

There are two types of Network Topology

Physical topology- that is, the arrangement of cables

Logical topology- that is, defines how the host access the media

What is an IP Address?

An Internet Protocol address is a sequence of numbers that signifies any device on the web. Computers operate IP addresses to communicate with each other both through the Internet and on other networks.

How many types of IP Addresses?

There are two types of IP Addresses

• Private IP Address

A private IP address is a domain of non-internet-facing IP addresses used in an internal network. Personal IP addresses are provided by network devices, such as routers, using network address translation.

• Public IP Address

The public IP address is an IPv4 address. Networking Interview Questions, If a resource in your occupancy needs to be directly connectable to the Internet, it must have a public IP address. Depending on the type of resource, there might be other requirements.

What are Firewalls?

A Firewall is a web security appliance that detects and filters incoming and outgoing network traffic based on an industry’s previously established security policies. A firewall is a barrier between a private internal network and the public Internet. A firewall’s primary purpose is to allow non-threatening traffic and keep dangerous traffic out.

There are two types of firewalls.

• Physical firewall

A physical firewall is also known as a hardware firewall. A hardware firewall is a physical appliance located to enforce a web boundary. Networking Interview Questions, All network connections crossing this boundary pass through this firewall, enabling it to inspect both inbound and outbound web traffic and enforce access controls and other security policies.

• Logical firewall

The logical firewall is configured to respond to the original/public address of the protected host and to do routing and Network Address Translation to and from the protected host for that traffic allowed by the firewall rules.

What is the source route?

Source routing is a process where senders can specify the route data packets take through a network. computer network, Networking Interview Questions, This allows for troubleshooting and various transmission goals. Source routing is an alternative to traditional routing, where containers move through a web-based on their destination.

What are Nodes and Links?

Nodes

A node is a fundamental data structure unit, such as a connected list or tree data structure. Nodes contain data and also may connect to other nodes. Pointers often implement links between nodes.

Links

A link is an HTML object that requires one to jump to a new location and then click or tap on it. Links originate on almost every WEBPAGE and provide a simple way of navigating between web pages.

What is the semantic gap?

The semantic gap is the difference between two descriptions of an object by different verbal representations, for instance, languages or symbols.

Define the brouter.

A brouter is an appliance that functions as a bridge and a router. It can forward data between networks and route data to individual systems within a network.

Networking Interview Questions for Experienced

There are some networking interview questions with answers for experienced.

What is process sigma?

Process Sigma measures the variation in a process relative to customer requirements expressed as several standard deviations on a normal distribution. Process Sigma will measure the frequency with which a task is performed without defect.

What is OSPF?

The OSPF protocol is one of a family of IP Routing protocols. Networking Interview Questions, It is an Interior Gateway Protocol for the Internet, used to distribute IP routing definition throughout a single Autonomous System in an IP network. The OSPF protocol is a link-state routing, meaning the routers exchange topology information with their nearest neighbors.

Define the 10Base-T.

IEEE designates 10BASE-T. The 10 prefers a maximum transmission speed of 10 Mbps. BASE refers to baseband signaling, meaning it can only carry Ethernet signals on the medium. T refers to twisted.

What is FMEA?

Failure Mode and Effects Analysis is an arranged way to signify and address potential problems or failures and their effects on the system either process before an adverse event occurs.

What is the Sliding Window?

Transmission Control Protocol uses the sliding window to manage bundle flow between two computers, either web hosts. TCP is a primary attribute of the IP suite and operates at the transport layer.

Define the SMTP.

The Simple Mail Transfer Protocol is an application mail server that sends, receives, and outgoing relay emails between senders and receivers. As the technology behind email communication, SMTP is the protocol that allows you to send and receive emails.

What is project 802?

Project 802 defines a standard for local area networks in which microprocessor-controlled terminals and other devices are coupled on a peer-to-peer basis. The paper provides a brief history, rationale for the effort, and an overview of the current draft standard.

What is NIC?

A network interface card (NIC) is a hardware component, typically a circuit board or chip, installed on a computer to connect to a network. A NIC provides a laptop with a dedicated, full-time connection to the web.

What is the datalink protocol?

Datalink protocols identify how appliances analyze and recover from such impacts and may provide mechanisms to reduce or prevent them. Networking Interview Questions, It is a set of specifications used to implement the data link layer just above the physical layer of the OSI model.

Defines the synchronous transmission?

The term synchronous describes a continuous and consistently timed transfer of data blocks. These connections are used when large amounts of data must be transferred quickly from one location to another.

What is asynchronous transmission?

Asynchronous transmission is data transmission in which each character is a separate unit with its start and stops bits and an uneven interval between them. Asynchronous transmission is also preferred as start/stop transmission.
