Before you register
How difficult is the CCDAK exam?
CCDAK is an Associate-level certification with moderate difficulty. It requires a solid understanding of Kafka core principles, Producer/Consumer API, Kafka Streams, and Connect. It is recommended to have 3-6 months of Kafka development experience and 1-2 months of systematic preparation.
What is the difference between CCDAK and Confluent Certified Administrator?
CCDAK targets developers and focuses on Kafka application development (Producer, Consumer, Streams, Connect); the Administrator certification targets operations staff and focuses on cluster deployment, monitoring, and management. Choose based on your job responsibilities.
How much does the CCDAK exam cost?
The CCDAK exam costs $150 USD, which is relatively affordable compared to other certifications. The exam is 90 minutes long, contains 60 multiple-choice questions, and requires a 70% score to pass.
How long is the CCDAK certification valid?
The CCDAK certification is valid for 2 years, shorter than most certifications. You need to retake the exam to renew after expiration. It is recommended to follow Confluent official exam update information.
Do I need to master Confluent Platform to take CCDAK?
Not entirely. CCDAK primarily tests core concepts of the open-source Apache Kafka, but it does cover Confluent ecosystem components such as Schema Registry and Kafka Connect. Familiarity with Confluent Platform is an advantage.
