Episode 8 — Use Network Tools Confidently: Testing Reachability, Name Resolution, and Paths (Task 10)
This episode teaches how to use foundational network testing concepts to validate what is truly happening during outages, suspicious behavior, or containment actions. You will learn how reachability tests differ from service availability, why name resolution issues can masquerade as application failures, and how path visibility helps confirm segmentation and routing assumptions. We will discuss typical troubleshooting logic used in security investigations, such as confirming whether a suspicious domain resolves internally, whether traffic is bypassing expected inspection points, and whether blocked access is actually blocked. You will also connect these techniques to exam scenarios that require selecting the next-best test or interpreting incomplete evidence. The goal is operational confidence: using simple checks to reduce uncertainty and avoid chasing false leads during time-critical incidents.
