DCA
Docker Certified Associate (DCA)
The Docker Certified Associate (DCA) validates expert-level proficiency in the Docker container platform, covering container lifecycle management, image building, networking, storage, orchestration with Docker Swarm, and container security. It is administered through Mirantis (which acquired Docker Enterprise) and is the benchmark credential for Docker practitioners in enterprise and production environments.

DCA Frequently Asked Questions
What does DCA stand for?
DCA stands for Docker Certified Associate (DCA). It is administered by Docker / Mirantis.
Who administers the DCA?
The Docker Certified Associate (DCA) (DCA) is administered by Docker / Mirantis. For official information, visit the Docker / Mirantis website.
How many questions is the DCA?
The DCA consists of 55 questions. Candidates are given 90 minutes to complete the exam.
What is the passing score for the DCA?
The passing score for the DCA is 65% (approx 36/55), as set by Docker / Mirantis. Scoring methodology and passing standards may be updated periodically. Always verify current requirements with the governing body.
How much does the DCA exam cost?
The DCA exam fee is $200 USD. This fee is set by Docker / Mirantis and may vary by testing centre, region, or membership status. Additional fees for registration or rescheduling may apply.
Is DCA still relevant with Kubernetes dominating orchestration?
Yes — Docker remains the standard container runtime, and Docker skills are foundational whether using Swarm or Kubernetes. The DCA tests container fundamentals (images, networking, storage, security) that are universal across all container platforms. Many organizations also continue using Docker Swarm for simpler workloads where Kubernetes overhead is unnecessary.
How hard is the Docker DCA exam?
DCA is considered moderately challenging for engineers with 6+ months of Docker production experience. Questions are scenario-based and test practical knowledge of Dockerfile optimization, network driver selection, Swarm service configuration, and security controls. Hands-on lab practice is strongly recommended alongside conceptual study.
What is the Docker DCA exam format?
55 questions (multiple choice, single and multi-response) in 90 minutes. A passing score of 65% is required. The exam is proctored online through Mirantis's testing platform. It covers Docker CE and EE features including Swarm mode, UCP (Universal Control Plane), and DTR (Docker Trusted Registry).
Should I take Docker DCA or CKA first?
Take DCA first if you are newer to containers — it builds foundational Docker and container networking knowledge that makes CKA study easier. Take CKA first if you already have strong Docker skills and want to focus on Kubernetes orchestration for production clusters. Both certifications complement each other well.
