Top 15 Network Support Technician Interview Questions and Answers

If you want to land a job as a network support technician, you must be prepared to answer relevant questions during the interview stage. It's not enough to have the technical know-how; you need to effectively articulate your skills and experience. Here are the top 15 network support technician interview questions with suggested answers to help you stand out from other candidates.

1. What do you understand by TCP/IP?

  • TCP/IP stands for Transmission Control Protocol and Internet Protocol. It is the foundation of the internet and networking, and it enables communication between different devices and networks.

    • 2. How do you troubleshoot a network connectivity problem?

  • The first step is to isolate the problem, check the cables and connections, and test the network hardware. If that doesn't solve it, then use network troubleshooting tools like ping and traceroute to determine where the issue lies.

    • 3. Explain what VLAN is and how it works.

  • VLAN stands for Virtual Local Area Network. It is a method of logically dividing a physical network into different segments. Traffic is isolated within these segments, allowing for better network security, efficiency, and management.

    • 4. What do you understand by DNS, and why is it important?

  • DNS (Domain Name System) is responsible for mapping domain names to their corresponding IP addresses, translating human-readable URLs into machine-readable IP addresses. DNS is essential for the effective functioning of the internet, browsers, and other networking applications.

    • 5. Explain the OSI model.

  • The OSI (Open Systems Interconnection) model defines a seven-layered networking model that illustrates how data is transmitted between devices. It starts with the application layer and moves to the physical layer, which represents the actual hardware that's sending and receiving data.

    • 6. What are the common network protocols that you're familiar with?

  • Some common network protocols are TCP, IP, UDP, DNS, FTP, SMTP, HTTP, and SNMP.

    • 7. What do you understand by DHCP?

  • DHCP stands for Dynamic Host Configuration Protocol. It's a protocol that automates the assignment of IP addresses and other network configuration settings to devices on a network, making it easier to manage a large network with many users and devices.

    • 8. How do you identify and resolve network security threats?

  • The first step is to identify a security threat, whether it's a virus, malware, or hacker. You can use various security tools, techniques and protocols to prevent these threats. Some common preventive measures include installing anti-malware software, configuring firewalls, and encrypting network traffic.

    • 9. What do you understand by IP addressing?

  • An IP address is a unique identifier assigned to every device on a network. It's a set of numbers that are used to identify, locate, and communicate with devices within a network.

    • 10. Do you have experience with cloud computing platforms, such as AWS or Azure?

  • Answer this question if you have experience with any cloud-based computing platforms. Highlight your experience with the specific platforms, including configuration, security, and scalability.

    • 11. Describe your experience with networking hardware like routers, switches, and hubs.

  • Outline any experience you have with networking hardware, explaining how you've used them, configured them, and troubleshot them in the past.

    • 12. How do you determine which network topology is best for a given situation?

  • The choice of network topology depends on several factors, such as the business requirements, the number of users and devices, and the distance between them. Be sure to note that there is no one-size-fits-all solution and that each situation will have unique requirements that must be carefully considered when selecting a network topology.

    • 13. What do you understand by SSH?

  • SSH (Secure Shell) is a secure network protocol that enables secure data transfer and remote access over an unsecured network. It's commonly used to securely access a remote server or device to perform administrative tasks.

    • 14. What experience do you have working with firewalls and VPNs?

  • Outline your experience working with and configuring firewalls and VPNs. Explain how you've protected networks and data by configuring firewalls to block unauthorized access and installing VPNs to secure remote access to the network.

    • 15. Describe your experience working with wireless networks.

  • Explain your experience working with wireless networks, including configuring wireless routers, setting up secure wireless connections, and troubleshooting issues with wireless networks.

    • Answering these questions will give interviewers insight into your technical knowledge, your proficiency in different networking technologies, and how well you can explain technical information in a clear and concise way. Good luck with your job search!
