Comparative Approach in Network Troubleshooting

What approach is the network engineer using to troubleshoot the network issue?

1) Top-down approach

2) Bottom-up approach

3) Divide and conquer approach

4) Comparative approach

Answer:

The network engineer is using the comparative approach to troubleshoot by comparing the network configurations before and after a routing protocol update, which is a common systematic problem-solving process.

Network troubleshooting can be a complex task, especially when dealing with issues arising from recent changes in network configurations. In this scenario, the network engineer is employing the comparative approach to investigate and resolve the network problem.

The comparative approach involves comparing the running configuration of the network before and after the implementation of the new routing protocol. By conducting a detailed analysis of these configurations, the engineer can identify any discrepancies or misconfigurations that may be causing the network to malfunction.

This methodical approach allows the engineer to pinpoint the specific differences between the two states of the network and determine the root cause of the issue. By systematically evaluating and comparing the configurations, the engineer can effectively troubleshoot and address the network problem.

In the context of network engineering, the comparative approach is a valuable tool for identifying and resolving network issues resulting from configuration changes. By leveraging this methodical problem-solving process, network engineers can ensure the efficient operation and performance of the network.
