The DCA certificationspecialization is ideal for developers, system administrators, and DevOps professionals who want to gain expertise in Docker technologies. It's also beneficial for anyone looking to validate their Docker skills by obtaining the Docker Certified Associate certification.

By taking the DCA specialization, you will gain an in-depth knowledge of Docker, which is useful for streamlining development and deployment, enhancing scalability, and improving collaboration in modern software development. 

Once you appear for the Docker Certified Associate (DCA) exam and pass it, the validity of the certification is two years. After that, you will need to update your certification every two years.

The Docker platform does not publish passing scores because the exam questions and passing scores are subject to change without notice. You have 90 minutes to complete 55 questions. There will be 13 multiple-choice and 42 discrete-option multiple-choice (DOMC) questions.
