Technical Skills & Experience

• 6. What is the difference between a router and a switch in a Cisco network?
  A: A router is a layer 3 device that connects multiple networks and directs traffic between them, while a switch is a layer 2 device that connects devices within a local area network (LAN).
• 7. How do you configure an access control list (ACL) on a Cisco router?
  A: To configure an ACL on a Cisco router, you need to use the "access-list" command and specify the source and destination IP addresses and port numbers. Then, you need to apply the ACL to a specific interface using the "access-group" command.
• 8. How do you troubleshoot a slow network connection on a Cisco router?
  A: First, I would check for any hardware issues such as faulty cables or network cards. Then, I would use network monitoring tools to check for any bandwidth usage spikes or unusual traffic patterns. If the issue persists, I would analyze routing protocols and QoS settings that could be causing the slow connection.
• 9. What is the purpose of VLAN trunking protocol (VTP) in a Cisco network?
  A: VTP is used to manage and synchronize VLAN information between switches in a network, allowing for easier administration and scalability.
• 10. Can you explain how you configure a switchport to be a part of a VLAN in a Cisco network?
  A: To configure a switchport as part of a VLAN, you need to use the "switchport access VLAN" command and specify the desired VLAN number. You also need to enable the switchport using the "switchport mode access" command if it is not already enabled.

Behavioral Questions

• 11. Can you give an example of a time when you identified a network vulnerability and suggested a solution?
  A: In my previous role, I noticed that the company's network devices were not regularly updated with the necessary security patches. I suggested implementing a patch management system, which was accepted and helped enhance the security of the network.
• 12. How do you handle difficult or challenging clients?
  A: I make sure to actively listen to their concerns and address them with empathy. I also try to explain technical concepts in a clear and non-technical manner to help them understand and feel more at ease.
• 13. Can you give an example of a time when you had to troubleshoot a complex network issue and keep a client updated through the process?
  A: Once, a client faced a network connectivity issue that affected their business operations. I was able to identify and resolve the issue, but it required multiple steps and some downtime. I regularly communicated with the client to provide updates and explain the process, which helped maintain a good relationship with them.
• 14. Can you tell us about a time when you had to handle conflicting priorities and how you managed them?
  A: In my previous role, I had to manage multiple projects with tight deadlines. To handle conflicting priorities, I made sure to prioritize tasks and delegate when necessary. I also communicated with team members regularly to ensure that each project was progressing as planned.
• 15. How do you handle unexpected changes or challenges in a network upgrade project?
  A: I make sure to carefully plan and document the upgrade process, including possible risks and backup plans. If any unexpected changes or challenges arise, I communicate with team members and stakeholders to discuss and find solutions that minimize downtime and impact on the project.

Situational Questions

• 16. A client is experiencing frequent network outages. How do you approach this situation?
  A: First, I would gather information about the outages, such as frequency, duration, and affected devices. Then, I would analyze router logs, traffic patterns, and other network factors to identify the root cause. Finally, I would suggest solutions to prioritize stability and prevent future outages.
• 17. How do you handle a situation where a piece of hardware fails during a network upgrade project?
  A: I would make sure to have backup hardware and a detailed disaster recovery plan in place to minimize downtime. I would also communicate with team members and stakeholders to determine the best course of action and keep everyone updated on the progress.
• 18. A client needs a new network security system installed, but their budget is limited. What do you do?
  A: I would analyze the client's needs and see if there are any cost-effective solutions that can still meet their requirements. I would also suggest implementing the most critical security measures first and gradually adding additional ones as budget allows.
• 19. How would you handle a situation where a team member is not keeping up with their responsibilities?
  A: I would first talk to the team member privately to understand their challenges and offer support. If the issue persists, I would discuss the matter with a supervisor and follow the company's processes for addressing underperforming employees.
• 20. A client is not satisfied with the network upgrade project you have completed. How do you handle their complaints?
