Course Description
This course provides practice exams for the OpenTelemetry Certified Associate (OTCA) certification. It is focused on exam preparation and assessment.
The course includes multiple practice tests delivered through Udemy's practice test system. Questions are multiple-choice and structured to reflect the format and difficulty level of the OTCA exam. Each question includes a clear explanation for correct and incorrect answers. Learners can review results, retake tests, and track performance to identify gaps and improve readiness.
Practice Test Features:
Practice mode: untimed, answers can be reviewed during the test, suitable for learning and revision
Exam mode: timed, answers are revealed only after submission, simulates real exam conditions
Detailed explanations for every question
Score reports and performance breakdown by topic
Unlimited retakes
The practice exams cover all OTCA knowledge domains, including:
