This episode discusses how to form a theory of probable cause after gathering information about a problem. We explain how to use evidence from logs, performance metrics, and user reports to eliminate unlikely factors and focus on the most probable source of the issue. This step ensures troubleshooting efforts are targeted and efficient.

We then explore examples, such as narrowing down a network outage to a faulty switch port or linking poor performance to a failing storage controller. Troubleshooting considerations include validating assumptions with quick, low-impact tests and being prepared to revise the theory if new evidence emerges. Mastery of this step ensures candidates can diagnose and resolve problems with precision.
