Top Basic Networking Interview Questions & Answers
The IT industry is on the rise and, as a result, competition in getting a job in networking has increased significantly. If you want to be successful then it’s essential that you prepare properly for your interview – not just with technical knowledge but also how to answer general questions too! To help get you started we’ve got some basic network-related question and answers which will give you an idea of what concepts are needed when hopping into this role. So firstly:
- What exactly is networking? Put simply, networking is the process of connecting two or more systems to share information. It requires rules, protocols and various pieces of tech such as routers, hubs and switches. A logical concern might be about network topologies? There are three principal ones in use with computer networks: Bus Topology; Star Topology and Ring Topology – each come stocked with their own pros & cons depending on what they’re being used for. And then there’s Network Protocols too – but what exactly are those?
- Do you know about networking security? It’s all to do with the measures put in place by organisations to protect their data from any potential threats or attackers. That includes policies and procedures, plus technologies like firewalls that an organisation implements to keep its information secure across computer networks against unauthorised access.
- Right then, let’s talk protocols – these are sets of rules which computers use on a network for transmitting data between two nodes on said network. The most popularly used ones today include TCP/IP suite, ARP protocol and FTP protocol. Now it pays dividends in interviews if one has solid knowledge around this topic so make sure you’ve done plenty of prep beforehand – don’t want your interviewer thinking otherwise!
Top Essential Computer Networking Interview Questions & Answers.
- What is Switch ?
A network switch is a device that is primarily used to allow for connections between two or more computers and/or other devices within the same local area network (lan). It enables data transmissions from one computer, by connecting it to another which allows communication with each other. In essence, they are responsible for enabling communications both locally and over wide networks. Network Switch links multiple computers together on Local Area Networks so they can share resources like files and access points – think of it kind of like ‘connecting dots’ across different systems allowing them all talk easily back n forth without any extra hassle or effort needed- pretty cool right!?
- Here, it would be beneficial for potential candidates to explain how switches differ from other devices such as routers, which operate at Layer 3 (Network Layer) of the OSI model.
- The next IT networking interview question could well be ‘What is a Subnet Mask?’ A subnet mask is used to divide up an IP address into two parts – one representing the host and another representing its network. By doing so, networks become more manageable by allowing them to split into several different segments or ‘subnets’. Doing simple maths calculations you can figure out whether two different subnets are the same or not. A good interviewee would also explain how a subnet mask creates the border between networks by providing each of them with its own unique address. Moving on from this…
- Your next IT networking job interview might cover slightly more specialised topics such as ‘What is VLAN and What Makes it Different to Traditional Network Models?’. Basically, virtual LANs (VLANs) have been created in order to compartmentalise those networks into broadcast domains which don’t overlap with one another – so what makes them distinct from other network models?
VLANs let you to segregate different types of traffic even when they’re passing through the same bits and bobs like switches and routers. What’s more, VLANs are a doddle to set up as there is no requirement for any physical modifications in traditional network topology; which makes them highly cost-efficient too! These were just some examples of questions regarding networking that could pop up during your journey towards getting employed. There are loads more topics related to computer networks that need brushing up on before going into an interview if you want the job!
