Pass Rate

Read the real blueprint and set up a lab
Week 1

10-12 hours this week

  • Download Docker Certified Associate Study Guide version 1.5 from the Mirantis certification page and read all six domain content-limit lists end to end
  • Build a three-node lab: three Linux VMs or three instances in labs.play-with-docker.com so you can form a real swarm rather than a single-node one
  • Install Docker Engine from the repository by hand on at least one VM, following docs.docker.com, so you have seen the repo setup and daemon.json steps the Installation domain asks about
  • Work through the DOMC sample test linked from the study guide so the YES or NO rhythm is familiar before it costs you marks
  • Write out the six domain weights and convert them into item counts: roughly 14, 11, 8, 8, 8 and 6 items out of 55
Images and Dockerfiles, the 20 percent domain
Week 2

10-12 hours this week

  • Write Dockerfiles that use ADD, COPY, VOLUME, EXPOSE and ENTRYPOINT and be able to say what each does differently from its neighbour
  • Read the Dockerfile reference and the image-building best practices pages on docs.docker.com
  • Practise docker image ls, docker image prune, docker rmi and docker system prune until you know exactly what each one removes
  • Use docker image inspect with --format and Go template syntax to pull out single attributes, since the blueprint names filter and format explicitly
  • Run docker history on a multi-stage build and a naive build of the same application and compare layer counts and sizes
Registries, tagging and signing
Week 3

9-11 hours this week

  • Run a local registry container, tag an image for it, then push, search, pull and delete
  • Enable Docker Content Trust with DOCKER_CONTENT_TRUST=1, sign an image and watch an unsigned pull fail
  • Read the Mirantis Secure Registry documentation to see what DTR features became, since the blueprint still uses the DTR name
  • Practise flattening an image to a single layer with docker export and docker import and know why you would do it
  • Clean up unused images on a filesystem and note the difference between dangling and unreferenced images
Swarm fundamentals, the largest domain
Week 4

12-14 hours this week

  • Initialise a swarm, join workers and managers, and read the join tokens with docker swarm join-token
  • Work out quorum for 1, 3, 5 and 7 managers and be able to say how many failures each configuration tolerates
  • Create replicated and global services, scale replicas up and down, and watch tasks reschedule when you drain a node
  • Apply node labels and use placement constraints so services land where you intend
  • Use templates with docker service create, for example a hostname built from the task slot
Stacks, compose files and troubleshooting
Week 5

11-13 hours this week

  • Convert a multi-container application into a compose file and deploy it with docker stack deploy
  • Learn which compose keys swarm honours under the deploy section, including replicas, placement, update_config, restart_policy and resources, and which keys it ignores
  • Break a service on purpose, then find the cause with docker service ps --no-trunc, docker service logs and docker service inspect
  • Perform a rolling update and then a rollback on a running service
  • Read the docker inspect output of a container, a service and a network and answer questions about the fields from memory
Networking
Week 6

11-13 hours this week

  • Create bridge, overlay, host, macvlan and none networks and describe when each fits
  • Deploy a service across an overlay network on two nodes and confirm service discovery by container name
  • Compare host mode and ingress mode publishing by publishing the same service both ways and observing the routing mesh
  • Configure a container to use an external DNS server with --dns and check /etc/resolv.conf inside the container
  • Read the Container Network Model description on docs.docker.com and be able to name the sandbox, endpoint and network objects
Security and the Docker Enterprise control plane
Week 7

10-12 hours this week

  • Read the Mirantis Kubernetes Engine documentation on RBAC, grants, collections and client bundles, and map each back to the UCP names in the study guide
  • Study mutual TLS in swarm: how manager and worker certificates are issued and rotated
  • Set up LDAP or Active Directory integration on paper, listing every field the control plane asks for
  • Practise creating Docker secrets and configs, attaching them to services, and confirming they appear under /run/secrets
  • Review image security scanning: what a scan reports, and what it does not catch
Storage, volumes and the Kubernetes objectives
Week 8

11-13 hours this week

  • Create named volumes, bind mounts and tmpfs mounts and be able to state which survives a container restart and which survives a host restart
  • Read the storage driver documentation on docs.docker.com covering overlay2, devicemapper and the Windows drivers, since the blueprint names graph drivers per operating system
  • Deploy a Kubernetes pod with a persistentVolumeClaim in kind or minikube and trace the chain from CSI driver to storageClass to claim to volume
  • Create a Kubernetes configMap and a secret and mount both into a pod
  • Expose a pod with a ClusterIP service and then a NodePort service and compare what each one reaches
Weak-domain repair
Week 9

10-12 hours this week

  • Score yourself domain by domain against the study guide bullet lists and mark every bullet you cannot demonstrate at a keyboard
  • Spend the whole week only on marked bullets, weighting your time by the 25, 20, 15, 15, 15 and 10 percent split
  • Rebuild the swarm lab from scratch without notes, timing yourself
  • Rewrite the trickiest Dockerfile from week 2 as a multi-stage build with a distroless or scratch final stage
  • Re-read every study guide bullet that begins with the word Describe, since those map to definitional items you can answer without a terminal
Format rehearsal and booking
Week 10

8-10 hours this week

  • Take the DOMC sample items again under time pressure and practise deciding each option in under 20 seconds
  • Run the equipment check: Zoom desktop client installed, Chrome with the proctoring extension, webcam visible to Chrome, and a speedtest.net result above 2 Mbps both ways
  • Confirm you are testing from Windows 7 or later, or macOS 10.8 or later, and arrange a supported machine if you only own a Linux box
  • Book the exam at store.mirantis.com and note that cancelling or rescheduling requires 48 hours notice
  • Do a final pass over the nine sample questions and answer key printed in the study guide
Working Full-Time Schedule

Duration: 15 weeks

Hours/week: 8 hours

Daily: ~2 hours on weeknights

Weekends: 3-4 hours Saturday + Sunday

Study during lunch breaks and commute time. Use weekends for deeper study sessions and practice tests.

Weekend-Only Schedule

Duration: 20 weeks

Hours/week: 6 hours

Saturday: 4-5 hours of focused study

Sunday: 3-4 hours of practice tests

Longer timeline but sustainable. Review flashcards on weeknights for 15-20 minutes to maintain retention.
