Free CompTIA Network+ N10-008 Practice Question

Considering a divide and conquer approach first helps isolate whether the issue is related to specific layers of the OSI model, such as the application layer for certain applications or the network layer for more general connectivity. Checking cable continuity would not isolate application-specific issues, whereas checking the correct VLAN assignment might be a step further down the troubleshooting process after determining that the issue affects multiple systems across the same network segment. Resetting all network devices is generally an unnecessary first step and does not directly contribute to establishing a theory of probable cause for application-specific issues.
