Which step in the Network Management System is focused on resolving network degradations and failures?

The focus on resolving network degradations and failures falls under the Network Operations step in the Network Management System. This phase is essentially dedicated to ensuring that the network operates smoothly and effectively. During Network Operations, various monitoring tools and protocols are employed to identify and address issues that may arise within the network, including any performance degradation or component failures.

Professionals in this area are responsible for troubleshooting network problems and implementing solutions to maintain optimal performance. This might involve real-time diagnostics, coordination with other teams for a comprehensive response, and employing strategies to restore service and minimize downtime.

In contrast, Network Planning is more about designing and preparing the network for future needs rather than dealing with immediate operational issues. Network Initialization focuses on setting up and configuring the network initially rather than ongoing problems. Network Security Assessment is dedicated to evaluating and improving the security measures in place and does not directly address network performance or operation issues. Thus, the role of resolving network degradations and failures is specifically aligned with the responsibilities under Network Operations.
