Technical Knowledge

• 6. What is the difference between IPv4 and IPv6?
  

  A: IPv4 and IPv6 are both internet protocol versions used for communication between devices on a network. The main difference between the two is the number of available IP addresses. IPv4 has a 32-bit address, allowing for approximately 4.3 billion addresses, while IPv6 has a 128-bit address, allowing for trillions of addresses.

• 7. Can you explain the OSI model and its layers?
  

  A: The OSI (Open Systems Interconnection) model is a conceptual framework used to understand how different devices communicate with each other over a network. It has 7 layers - Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer performs a specific function, such as managing data transmission or converting data into a readable format.

• 8. How do you ensure network security?
  

  A: I implement various security measures, such as firewalls, encryption, and access control, to protect the network from unauthorized access and potential cyber threats. Regular security audits and updates are also important to ensure the network is always protected.

• 9. Can you troubleshoot issues with a malfunctioning hard drive?
  

  A: Yes, I have experience with troubleshooting hard drive issues, such as data corruption or mechanical failure. I use diagnostic tools to identify the problem and attempt to repair the drive, if possible. If the issue cannot be resolved, I make sure to safely backup and recover important data.

• 10. Do you have experience with virtualization technology?
  

  A: Yes, I have experience with virtualization technology, such as VMware and Hyper-V. I have set up and managed virtual environments for testing and development purposes, as well as for saving costs and improving efficiency in a production environment.

Behavioral Questions

• 11. How do you handle a conflict with a team member?
  

  A: I believe in addressing conflicts openly and directly, while also maintaining a professional and respectful attitude. I try to identify the root cause of the conflict and work towards finding a mutually beneficial solution. If necessary, I involve a mediator for assistance.

• 12. Can you give an example of a time when you had to adapt to a new technology or process quickly?
  

  A: In my previous role, we had to switch from using Microsoft products to open-source software due to budget constraints. I quickly researched and familiarized myself with the new software and was able to successfully implement it within a short timeframe. I also trained my team on the new technology and we were able to continue our work smoothly.

• 13. How do you handle a situation where you are unable to meet a deadline?
  

  A: If I am unable to meet a deadline, I communicate this as soon as possible and explain the reasons why. I also offer potential solutions and seek guidance from my supervisor to determine the best course of action. I always make sure to prioritize the most critical tasks to ensure any delays do not affect the overall project timeline.

• 14. How do you keep your skills up-to-date in this rapidly changing field?
  

  A: I am continuously learning and seeking opportunities to enhance my skills through training programs and certifications. I also enjoy experimenting with new technologies in my spare time and am always eager to expand my knowledge in this rapidly changing field.

• 15. Can you describe a time when you had to troubleshoot a difficult issue and what steps you took to resolve it?
  

  A: In my previous role, we had a network outage that affected a crucial system. After extensive troubleshooting and analysis, we discovered the issue was caused by a faulty switch. We quickly replaced the switch and restored the network, while also proposing a backup plan for similar incidents in the future.

Situational Questions

• 16. If a colleague asks for your help with a task but you are busy with your own tasks, how do you respond?
