Largest Domain

Orchestration

The DCA exam uses 55 questions in 90 minutes and Mirantis does not publish a numeric passing score. The official January 2025 study guide weights Orchestration at 25%, Image Creation, Management, and Registry at 20%, Installation and Configuration at 15%, Networking at 15%, Security at 15%, and Storage and Volumes at 10%. As of March 10, 2026, Mirantis still lists the exam publicly at $199, but no newer public blueprint than the January 2025 guide is posted.

About the DCA Exam

The Docker Certified Associate validates practical knowledge of Docker Engine installation and administration, image creation and registry workflows, swarm orchestration, networking, security controls, and container storage. The public Mirantis materials still use Docker Enterprise, UCP, and DTR terminology, so candidates should be comfortable with both legacy product names and modern Mirantis context.

DCA Study Tips from Top Performers

1Prioritize orchestration first because it carries 25% of the exam and touches swarm services, scaling, updates, and stacks.
2Memorize Dockerfile instruction behavior, layer caching, build context, and image tagging because image workflows account for 20% of the blueprint.
3Drill command-line tasks hands-on: `docker service`, `docker node`, `docker network`, `docker volume`, `docker stack`, and common `docker run` flags.
4Review legacy Docker Enterprise, UCP, and DTR terminology alongside modern Mirantis wording because the public DCA guide still uses those names.
5Know the difference between volumes, bind mounts, tmpfs, overlay networks, bridge networks, and port publishing because these concepts are easy to confuse under time pressure.
6Treat security as operational, not abstract: practice TLS, content trust, swarm mTLS, RBAC, least privilege, and image-scanning concepts.

Frequently Asked Questions

Is the DCA still available in 2026?

Yes. Mirantis still publicly lists the Docker Certified Associate for purchase as of March 10, 2026, with a listed fee of $199 USD. The public blueprint still points to the January 2025 study guide, so candidates should expect legacy Docker Enterprise terminology such as UCP and DTR.

What is the DCA exam format?

The official DCA page lists 55 questions in 90 minutes. Mirantis states the exam contains 13 multiple-choice items and 42 discrete-option multiple-choice (DOMC) items, so the live exam is not a plain four-option multiple-choice test even though practice banks usually are.

What is the passing score for DCA?

Mirantis does not publish a numeric passing percentage for the DCA. Your score report is pass/fail, so preparation should focus on consistent performance across all six domains rather than chasing an unofficial cutoff.

Which domains matter most on the DCA exam?

Orchestration is the largest domain at 25%, followed by Image Creation, Management, and Registry at 20%. Installation and Configuration, Networking, and Security are each 15%, while Storage and Volumes is 10%.

How should I prepare for the DCA?

Start with Docker Engine fundamentals, then spend most of your time on swarm services, Dockerfiles, registries, networking, and security workflows. Practice commands hands-on, review legacy UCP and DTR terminology from the official guide, and use timed question sets to close weak areas.

Were there any 2026 DCA blueprint changes?

No newer public blueprint than the January 2025 DCA study guide was posted by Mirantis as of March 10, 2026. The main public change visible in 2026 is that Mirantis still sells the exam while some supporting policy pages use newer scheduling and cancellation wording than the older DCA FAQ, so blueprint content appears stable but operational policies should be checked at booking time.
