Question the Obvious

A troubleshooting principle of checking simple causes first, such as power, cables, and settings.

Definition

Many problems stem from unplugged cables, disabled devices, switched-off monitors, or toggled settings. Asking open-ended questions and verifying basics before deep diagnostics saves time. It is part of establishing a theory of probable cause.

Example

Confirming the monitor is on the correct input before replacing a graphics card.

Exam tip

Exam answers that check simple physical causes first are usually correct.
