Summary  
This chapter presents a structured diagnostic approach combining symptom identification, component isolation, configuration verification, and specialized tools to uncover the root causes of system issues.  

General domain of usage  
Network troubleshooting

**Network diagnostics** goes beyond basic troubleshooting by focusing on identifying and addressing specific, underlying issues that may affect the network's performance or security. This chapter introduces a more systematic approach to diagnosing problems, including methodologies and **best practices** for effective network diagnostics. Rather than merely identifying issues, the goal is to understand the **root causes** to implement precise, lasting solutions.

### Methodical Problem-Solving

**Step 1: Identify the Symptoms**
- Begin by documenting what the problem looks like. For instance, is it a total loss of connectivity, slow speeds, or intermittent failures? This helps in narrowing down where to start.

**Step 2: Verify the Basics**
- Ensure basic configurations are correct: check cables, connections, IP addresses, and device settings. Always eliminate the simplest explanations first.

**Step 3: Isolate the Problem**
- Systematically isolate components to identify where the issue lies. For example, disconnect certain parts of the network to see if the problem persists.

Which of the following is an effective way to consolidate network diagnostic data?
