Question: 1 / 400

What is a common approach to troubleshoot network issues?

Checking user manuals for device specifications

Running a full system virus scan

Checking connectivity and configuration settings

The approach of checking connectivity and configuration settings is fundamental in troubleshooting network issues because many problems arise from incorrect settings or connectivity failures. This includes verifying physical connections, such as cables and ports, as well as examining configuration settings like IP addresses, subnet masks, and gateway information. Ensuring that devices are communicating properly and that configurations align with the network's design is crucial in identifying and resolving connectivity issues.

By focusing on these areas, a technician can often quickly pinpoint the source of a problem or rule out potential issues, making it an effective first step in the troubleshooting process. This method is more efficient and effective than immediately replacing hardware or performing unrelated tasks like virus scans, which may not address the underlying network problem.
