Which step comes first in the networking troubleshooting methodology?

1. Establish a theory of probable cause

2. Identify the problem

3. Create a plan of action

4. Document findings

The correct answer is: Identify the problem

Identifying the problem is the crucial first step in the networking troubleshooting methodology because it sets the foundation for the entire troubleshooting process. Without a clear understanding of what the issue is, any subsequent actions may be misguided or ineffective. This step involves gathering initial information about the symptoms of the problem, including error messages, user reports, and the context of the issue. By focusing on identifying the problem first, a technician can gather necessary details that will inform later steps, such as establishing a theory of probable cause and creating a plan of action. This structured approach ensures that the troubleshooting process is methodical and targeted toward resolving the actual issues rather than just symptoms. It also helps in confirming if the problem is repeatable and understanding its impact on the network, which is essential for effective resolution.
