I recently completed this new version of the exam, and ... barely passed it.
I have no idea why this exam is called docker certification, half of it is kubernetes, but whatever, I kind of knew that anyways.
So for my version of the exam (not sure if they have different variants)
- 13 multiple choice questions, the rest DOMC, which kind of suck (You can only go back and review the 13 multiple choice questions)
- Lots of kubenetes, but mostly within the realm of PV, PCV, storage classes, pods, nothing too amazingly crazy
- Quite a few questions of Docker EE stuff (UCP, DTR)
- Not so heavy on the very basic docker functions, but who knows if that was my variant of the test.
##My Preparation Time Spend
- About a month
- Speed roughly 7-8 hours per week.
- Typically study at a coffee shop before work for a solid hour. Then 2 hours each day on the weekends.
- Tried studying after work, but I’m mentally drained after work.
##My Preparation Material
Preparation was tough because most (if not just about all) of the learning resources online are not up to date with the new exam changes. This is definitely not the most optimal way, but it worked for me for my experience level.
- [Linux Academy - Docker Certified Associate (DCA) Course](https://app.linuxacademy.com/) (took notes watching, not up to date as of now, but it is what it is) (Flash cards were pretty helpful to go through when I had a minute on the toilet 🙂 )
- [Docker Deep Dive - Nigel Poulton](https://www.amazon.com/Docker-Deep-Dive-Nigel-Poulton-ebook/dp/B01LXWQUFF)
- [The Kubernetes Book - Nigel Poulton](https://www.amazon.com/Kubernetes-Book-Version-November-2018-ebook/dp/B072TS9ZQZ)
- [Linux Academy Kubernetes Essentials (took notes watching)](https://app.linuxacademy.com/)
- Official and Provided DCA Study Guide
- [Medium Article - "250 Practice Questions for the DCA Exam"](https://medium.com/bb-tutorials-and-thoughts/250-practice-questions-for-the-dca-exam-84f3b9e8f5ce)
- [Docker Certified Accosiate Practice Tests - Jonnathan Middaugh (E-Book)](https://www.amazon.com/Docker-Certified-Associate-Practice-Tests/dp/B08CJXNC3R) (He does provide an additional "practice exam" for kubernetes for free online on medium)
- Scanning through [official online docker documentation](https://docs.docker.com/). God, do they have good documentation! Great examples as well.
- Scanning through [official online kubernetes documentation](https://kubernetes.io/docs/home/)
- ["Play with Docker"](https://www.docker.com/play-with-docker) and ["Play with Kubernetes"](https://labs.play-with-k8s.com/) helped
##My Experience Before the Exam:
- ~1 year (Nothing complicated, nothing custom or crazy)
- Basic Dockerfile, docker-compose, pull, build, run, etc
- Never touched kubernetes before
- Never touched Docker EE before
##Some Exam Advice:
- Stay organized and have a plan when studying. Don't get overwhelmed.
- Read the questions very carefully and slowly. You have more than enough time to read questions slowly 2-3 times to really get what it's saying and the details presesnted.
- Sometimes they will mix kubernetes and docker concepts/terms, which is good because it lets you eliminate options pretty quick
- You'll probably come along Medium articles that are behind paywall and locked. Add this thing your bookmark bar (instructions on their site): https://sugoidesune.github.io/readium/ . Any time you come across one of those articles, hit the bookmarked link to get access to the article.
