CNCF-OTCA: CNCF OTCA (OpenTelemetry Certified Associate)
Master the OpenTelemetry Certified Associate (OTCA) exam - OpenTelemetry's vendor-neutral observability model: the three signals (traces, metrics, and logs) plus baggage, semantic conventions, manual and automatic instrumentation, the API-versus-SDK split, TracerProvider/MeterProvider/LoggerProvider with processors, exporters, and samplers, W3C Trace Context and baggage propagation, OTLP export, and the OpenTelemetry Collector's receivers, processors, exporters, connectors, and extensions wired into per-signal pipelines, agent-versus-gateway deployment, scaling, and debugging observability pipelines.
$79 practice exams are gatekeeping. Mine are $9 because it should be. Written by someone who works in cloud and AI at Microsoft NZ — for people like us.
I just passed with a 777 (Yes, Seriously). This video helped me tremendously.
