Datadog Fundamentals case studies
Datadog Fundamentals · Put your knowledge to work in context.
The Datadog Fundamentals credential is an entry-level certification that validates a working knowledge of the Datadog platform - how its products fit together and how telemetry from infrastructure, applications, logs, front-end experiences, and security signals is collected, explored, and acted on. Datadog publishes a dedicated Fundamentals Certification Learning Path in its Learning Center, described there as a 16-course path whose courses cover the topics in the Datadog Fundamentals Certification exam, so the vendor's own curriculum is the natural backbone for preparation. The Datadog Fundamentals case studies are 5 cases and about 3,669 words.
