CCDAK covers Confluent and Apache Kafka with a precise focal point on the expertise of the platform wanted in order to strengthen purposes that work with Kafka. This consists of everyday information of Kafka elements and architecture, designing, monitoring, and troubleshooting in the context of Kafka, and improvement of customized functions that use Kafka’s APIs. This route is meant to inform you via the essential matters and assisting cloth that you will want to be acquainted with in order to prevail in your Confluent CCDAK certification. Confluent Certified Developer for Apache Kafka (CCDAK) certification will add an area of expertise to your resume. In the cutting-edge market, this certification is no longer a requirement with the aid of agencies; however, it really provides weight to your job application. By clearing its exam, one can gain documented proof of having command over the Apache Kafka technology.
The aforementioned functionalities of Apache Kafka are performed via its four core APIs. The Producer API approves a utility to post one or extra streams of information to a precise subject or set of topics. Conversely, the Consumer API lets software subscribe to a unique theme or set of subjects for processing the movement of documents produced by way of them. The Streams API serves as the movement processing unit and, consequently, tactics enter streams from a single or a couple of subjects to produce output streams for one or a couple of topics. Finally, the Connector API lets in setting up and executing producers and buyers which are linked to current functions and statistics systems.
Exam Pattern:
The examination itself is divided into three domains. Application Design is the greatest component of the examination and roughly contributes to 40% of the questions, whereas Development and Deployment/Testing/Monitoring are given a weight of 30% each. The Exam Code is CCDAK.

Perquisites:
There are two units of know-how quintessential for creating the required skill ability level. The first set is the Product Knowledge of the associated Confluent products. It is anticipated that the candidate performing for the examination has at least labored for 6-12 months with Confluent products.
The nature of the examination is such that a hands-on journey with Kafka Producer, Kafka Consumer, Kafka Streams, Kafka Connect, and KSQL queries is indispensable for success. Furthermore, conceptual expertise of software constructing and networking between Confluent merchandise is predicted as well.
The 2nd set is the generalized IT Knowledge. Familiarity with applicable programming languages such as Python (how to turn out to be a python developer article) and Java (checkout whether or not Udemy is exact for mastering Java) is wanted alongside in-depth expertise of at least one of them. Other vital areas of understanding encompass perception of networking, the know-how of dispensed systems, flow processing, and familiarity with Linux/Unix.
LinkedIn Learning #0 — Same guides; however, for free
This is a beginning role for you when it comes to getting ready for the Apache Kafka CCDAK exam. It would be dull to expect that you don’t understand both Java and Scala programming already as you prefer to put together for the CCDAK exam; however, my quality advice would be for you to take some of the guides on LinkedIn Learning to refresh your programming skills.
Udemy direction #1 – Learn Apache Kafka for Beginners v2
In the Apache Kafka collection accessible on Udemy, “Learn Apache Kafka for Beginners” is the entry factor in your experience to prepare yourself for the CCDAK exam. There are a few prerequisites in areas that are vital for maximizing the advantage of this course. One needs to have a real-looking grip on Java programming and its realistic usage. Furthermore, it is additionally right to have a perception of the use of the Linux command line as well. This path establishes the core standards of the Apache Kafka ecosystem and teaches how to make a non-public improvement environment.
Udemy route #2 – Kafka Connect Hands-on Learning
The 2d direction in the collection focuses on Kafka Connect, which is a scalable device for streaming records between Apache Kafka and exterior systems. In addition to the expertise received from the simple Kafka course, one should additionally comprehend Docker. It offers special operations of Kafka Connect. You examine the structure and fundamentals of Kafka Connect that allow you to write your very own Kafka Connector. Knowledge of configuration and execution of each Source and Sink Connectors is furnished in this course.
Udemy route #3 – Kafka Streams for Data Processing
As the identity suggests, this unique route pursues Kafka Streams which can be considered as a movement processing unit. Again prior understanding of Apache Kafka is wished to recognize the direction alongside with a grasp of Java eight programming language. The improvement and scaling of Kafka Stream functions is a key takeaway from this course. As a result, this equips you to write and bundle your personal application. More specifically, a configuration of Kafka Streams for the usage of Exactly Once Semantics, making use of high-level DSL whilst programming Kafka Streams, and writing assessments for Kafka Streams topology is amongst the vital getting to know outcomes.
Udemy route #4 – KSQL for Stream Processing – Hands On!
The “KSQL for Stream Processing – Hands On!” route revolves around Confluent’s movement processing framework, KSQL. The path itself does no longer have any obligatory prerequisite statistics aside from the fundamentals of Apache Kafka. However, grasp of Kafka Streams would expedite the gaining knowledge of manners and enhance the journey of the course. This path covers all the fundamentals of KSQL, so a lack of familiarity with it would now not cause any issues.
Udemy route #5 – Confluent Schema Registry & REST Proxy
In this unique course, three vital Confluent merchandise are taught, which offers a higher perception of the world of Apache Kafka. Apache Avro is an environment-friendly information serialization mechanism, Confluent Schema Registry is the go-to approach for storing Avro schema for the applicable matters, and Confluent REST Proxy is a fantastic way for verbal exchange of Avro records besides the usage of Java. The route starts off with easy Avro schemas and progressively strikes in the direction of extra complicated ones. It additionally introduces how a Java Producer and Consumer can make use of Avro information and Schema Registry.
Udemy direction #6 – Kafka Cluster Setup & Administration
As installed earlier, a Kafka cluster is a crew of servers that may additionally be at a couple of locations. This route focuses on putting up and the administration of Kafka clusters. That is why, aside from the standard prerequisites that we have found so far, information on servers and AWS is additionally wanted for this specific course. This path introduces the thinking of the Zookeeper cluster and its hyperlink to Kafka. It additionally teaches how to set up specific administrative equipment such as Kafka supervisor and the use of Docker.
Udemy path #7 – Kafka Security (SSL SASL Kerberos ACL)
Kafka safety is a vital phase of Apache Kafka to ensure the safety of record streams. It is divided into three parts: Encryption (SSL), authentication (SSL and SASL), and authorization (ACL). This route takes matters from scratch in phrases of safety, so no prior information of SSL, SASL, and Kerberos is needed. However, as we have come to expect, understanding Kafka and Linux are necessary. It covers the setup and utilization of all three essential components, i.e., SSL, SASL, and ACL.
Udemy direction #8 – Kafka Monitoring & Operations
The direction focuses on three fundamental pillars for Apache Kafka: Administration, monitoring, and operations. An appreciation of Kafka and Linux is naturally required for this course. This route imparts know-how concerning the setup of monitoring and administration mechanisms. The monitoring setup is accomplished by the use of Grafana and Prometheus whilst for administration, equipment such as Kafka supervisor are used. Different operations involving Kafka clusters are discussed.
Udemy path #9 – Confluent Certified Developer for Apache Kafka (CCDAK)
The closing piece of the puzzle, this direction is essentially a set of one hundred fifty CCDAK examination questions. After protecting all the direction material, this direction has to grant adequate exercise earlier than the examination itself. The route includes three exercise tests, each with 50 questions.
