About this exam

The Confluent Certified Developer for Apache Kafka (CCDAK) is one of the certifications Confluent offers to validate Apache Kafka expertise. Confluent describes it as designed for developers and solution architects who build applications with Apache Kafka, validating the essential knowledge needed to develop, deploy, and maintain robust, real-time streaming applications using Kafka's core APIs and platform capabilities. It is a practitioner credential: you should already be comfortable producing and consuming records, reasoning about partitions and consumer groups, and shipping code against Kafka rather than only administering clusters. Confluent positions certification as a differentiator in the job market, useful in promotion discussions and when applying for new roles. The exam is a 90 minute proctored exam delivered remotely; question types vary and include multiple-choice, matching, and list order. You take it from a computer with a webcam, microphone, speakers, Google Chrome, and a strong internet connection, and you must present a government ID. No training class is required, but Confluent recommends reviewing the official exam guide for the exam you plan to take and taking recommended training. Results appear on the testing screen immediately after you finish. Passing earns the credential and a digital badge, and the certification expires after two years, so re-certification is required.

What you'll study

Common questions

About Confluent Apache Flink Certificate preparation

How long is the CCDAK exam and what question types appear?

It is a 90 minute proctored exam. Question types vary and include multiple-choice, matching, and list order, so prepare to recall facts precisely and to sequence or pair concepts correctly rather than only picking one option from four. The exam is proctored remotely for its full duration.

Where and how do I take the exam?

Remotely, from anywhere meeting the internet, security, and privacy requirements. You need a webcam, microphone, speaker capability, Google Chrome, a strong internet connection, and a government ID. Install the Honorlock Chrome Extension and run a System Check before launch; if your internet speed does not meet requirements, your attempt may be forfeited.

What happens if I fail - when can I retake?

Candidates must wait 7 days before purchasing and taking another exam. After 7 days, the exam becomes available for repurchase and registration in your training account. Plan your schedule with that gap in mind, and use the waiting period to review the official exam guide and the areas you missed.

Can I reschedule or cancel my appointment?

You may reschedule or cancel five or more calendar days before the appointment date. Within 5 days, rescheduling is not available, and candidates who cancel inside that window must reapply before scheduling again. If you fail to cancel or reschedule in time, exam fees are nonrefundable.

When do I get my results, and what do I receive if I pass?

Results appear immediately on the testing screen after you complete the exam. If you pass, you earn the certification credential and may use the certification title and logo on business cards and professional collateral under the Confluent Certification Agreement. You also receive an email with instructions for accessing your digital badge and certificate.

Does the certification expire?

Yes. The certification expires after two years, and you are required to re-certify every 2 years. Treat the credential as a renewable commitment rather than a one-time achievement, and track your expiration date so re-certification does not lapse unexpectedly.

Is a training class required before taking the exam?

No. Confluent states it is not required to attend a training class, though recommended training assists preparation. Confluent advises reviewing the online study guide for the exam you are preparing to take. A sensible order is the official exam guide first, then hands-on practice with Kafka's core APIs, then targeted review of weak areas.

What should I have ready on exam day, and what is prohibited?

Have a computer with a video camera, audio including microphone and speakers, Google Chrome, a strong internet connection, and a government ID for identity verification. Reference materials and mobile phones are prohibited during the examination. You must also accept the Confluent Certification Program Agreement during registration and at the start of the exam.

What language is the exam in, and can I request an accommodation?

All exams are in English. If you would like to request a language accommodation, you may do so by contacting [email protected]. Candidates with a disability that might affect performance can also contact that address, at least 21 days in advance of the test date, to discuss available accommodations.

No. Confluent Certification is not affiliated with the Apache Software Foundation.
