Failed Docker Certified Associate? Here's Your Recovery Plan

Failing an exam doesn't define you. The Docker Certified Associate has a pass rate of ~65%, you're not alone. Here's exactly what to do next.

You're Not Alone

The Docker Certified Associate has a pass rate of ~65%, which means many qualified candidates don't pass on their first attempt. This is a hard-difficulty exam that challenges even experienced professionals.

Most people who fail and try again with a better strategy pass on their second attempt. The key is understanding what went wrong and fixing it.

Mirantis (formerly Docker) Retake Policy

Wait Period

14 days from the day you fail before you may sit the exam again, per the Mirantis DCA FAQ.

Retake Cost

Full price every time: USD 199 or EUR 200. Mirantis states that payment is good for one exam attempt. Multi-packs of 10, 25, 50 or 100 exams are discounted, arranged by contacting Mirantis.

Max Attempts

Mirantis publishes no lifetime attempt cap. The only stated conditions are the 14-day wait and payment for each attempt.

Pro tip: There are two separate ways to lose a fee without answering a single question. Cancelling or rescheduling inside 48 hours of the appointment forfeits the fee, and failing to start within 15 minutes of your slot marks you a no-show. Arriving without every required form of identification also counts as a missed appointment and forfeits the fee. If your connection falls below the 2 Mbps requirement, Mirantis warns the attempt may be forfeited, so run the speed test in advance and email [email protected] if the numbers look marginal.

Common Reasons People Fail Docker Certified Associate
  • Preparing as though the DCA were a hands-on lab exam like the CKA
    There is no terminal. All 55 items are questions: 13 standard multiple choice and 42 DOMC. Lab work matters because it makes you fast at recognising correct command syntax and inspect output, so rehearse recognition rather than typing speed.
  • Answering DOMC items the way you answer normal multiple choice, by scanning for the best-looking option
    Caveon states the item closes as soon as it has been answered correctly or incorrectly. You never see the full option set, so a hasty YES on a plausible distractor ends the question wrong. Judge each option strictly on its own truth value.
  • Skipping UCP and DTR because those products were renamed years ago
    Study guide version 1.5 from January 2025 still names UCP and DTR in the Installation, Networking, Security and Storage domains. Client bundles, RBAC grants, LDAP integration, external certificates, HA installs on AWS and backup procedures are all live objectives.
  • Assuming the exam avoids Kubernetes because Docker sells Swarm
    The blueprint puts Kubernetes objectives in four domains: pods and deployments, configMaps and secrets, ClusterIP and NodePort services, persistentVolumes, and the CSI driver to storageClass to persistentVolumeClaim chain. Build a kind or minikube cluster and cover them.
  • Pacing against a 65 percent cut score found on a third-party site
    Mirantis states it does not publish passing scores because questions and passing scores change without notice. Aim to answer everything correctly rather than budgeting a number of misses you believe you are allowed.
  • Practising with docker compose up and never with docker stack deploy
    Orchestration is 25 percent of the exam and it tests stacks. Learn which compose keys swarm honours under the deploy section and which it silently ignores, because those distinctions make good exam questions.
  • Dismissing devicemapper and the older graph drivers as obsolete
    Domain 6 names configuring devicemapper and identifying the correct graph driver per operating system. The blueprint is older than your production stack, so learn the drivers it names, not only overlay2.
  • Never reading docker inspect output carefully
    The Orchestration domain lists interpreting the output of docker inspect as an objective in its own right. Run it against a container, a service, a network and a volume and learn where mounts, networks, state and labels appear in the JSON.
  • Planning to test from a Linux workstation
    Mirantis states Linux is not supported for the remotely proctored exam. You need Windows 7 or later or macOS 10.8 or later, plus the Zoom desktop client and Chrome with a proctoring extension. Sort the machine out before you book.
  • Booking a slot with no margin and losing the fee
    You must start within 15 minutes of the appointment time or the system marks you a no-show, and cancelling or rescheduling requires 48 hours notice. Both failures forfeit the fee, which means paying the full USD 199 again.
Your 5-Step Recovery Plan
1

Analyze Your Score Report

Review your Docker Certified Associate score report immediately. Identify which domains you scored lowest in, these are your priority areas. Write down specific topics you struggled with while the exam is fresh in your memory.

2

Take a Short Break (But Not Too Long)

Take 2-3 days off from studying to reset mentally. Failing is emotionally draining, and jumping back in immediately can lead to burnout. But don't wait too long, the material is still fresh.

3

Change Your Study Strategy

Whatever approach you used before didn't work. Switch it up: if you only read textbooks, add video courses. If you didn't do practice tests, make them your primary study method. Active recall beats passive review every time.

4

Focus on Weak Areas (80/20 Rule)

Spend 80% of your study time on the 2-3 domains where you scored lowest. You probably already know the topics you scored well on. For Docker Certified Associate, this targeted approach is far more effective than re-studying everything.

5

Take a Practice Test Before Rebooking

Don't rebook the exam until you're consistently scoring 85%+ on practice tests. This saves you money and builds real confidence. When you're scoring well, schedule the retake.
