Network monitoring Problem-Solving and Analytical Questions

1. You have a network topology diagram with three routers connected to each other in a triangular formation. Each router has a different latency for communications. How would you design a data flow strategy to minimize overall latency between two endpoints connected through the routers?

2. You monitor a network experiencing intermittent connectivity issues. A packet capture shows that the response times for one specific server have doubled. Describe a systematic approach to identify the cause and resolve the issue.

3. You have a network where the bandwidth usage is consistently above 90%. Outline how you would analyze the traffic distribution and identify which applications or users are consuming the most bandwidth.

4. Given a scenario where network performance degrades during peak hours, you are provided with historical data on bandwidth usage, application performance, and user activity. What methods would you use to interpret this data, and what conclusions could you draw to propose a solution?

5. A network consists of multiple subnets, and you are tasked with troubleshooting a connectivity issue in one particular subnet. What steps would you take to diagnose the problem, and how would you determine if it's a network or configuration issue?

6. You are monitoring a large network and received alerts about high CPU usage on a particular switch. How would you approach diagnosing the cause of this high CPU load? What data would you gather and analyze?

7. You’re tasked with optimizing routing protocols on an enterprise network. Explain how you would evaluate the current routing configurations and what metrics or data points you would analyze to recommend improvements.

8. A company has multiple remote sites connected via a VPN. Randomly, users at one site report being unable to access an internal application, while others are unaffected. Describe your analytical approach to investigate and resolve this issue.

9. You notice a significant number of retransmissions from a specific segment of the network. What steps would you take to analyze the root cause, and what tools would you use to gather relevant data?

10. During a network outage, you have access to log data from multiple devices in the path. Describe your process for interpreting this log data to identify the point of failure.
