1.Gather Information-Start by collecting information about the problem. 2.Isolate the Issue-Try to isolate the specific part of the network where the problem is occurring. 3.Check Hardware-If the issue involves specific hardware verify. 4.Review Configurations- Examine the network configurations to ensure they are correct and consistent with your network design. 5.Update Firmware and Software- Make sure that all network devices have the latest firmware and software updates. 6.Check for Network Congestion- Network congestion can cause performance issues. 7.Collaborate with Colleagues or Vendors- Don't hesitate to reach out to colleagues, vendors. 8.Consider Outside Help- If the issue persists and you're unable to resolve it internally

In my experience, Dealing with Complex network problems first defines the problem and its impact. The next step is to narrow down to see which area must hit hardware /software. After identification and fix, Ensure 100% Testing with defined QoS. Also, make sure to document these types of incidents for future learning

To tackle complex network problems, adopt a structured approach. Isolate issues through logical segmentation, then methodically eliminate potential causes. Utilize diagnostic tools, logs, and network mapping. Collaborate with experts, sharing knowledge and insights. Implement incremental fixes, testing and validating each step. Document the process and resolution for future reference. Consider scalability, security, and redundancy to prevent recurrence.

- It is important to visualize network through detailed network diagrams showing all possible details. that saves time to resolve issues. in addition to Low Level Design Document (LLD). Sometimes the smallest detail can tackle a problem.
