6.0 Storage and Volumes: 83%
Some things I would like to point out:
1. Storage-related questions were deeper than I expected.
2. Understing Namespaces and Cgroups, and how Docker uses them will net some easy points.
3. There was less DTR/UCP-specific content than I feared. I had no prior EE experience.
4. At least three questions involving docker secrets, I probably got them all wrong. I recommend reading the docs on secrets.
5. The proctored exam is very serious about your desk and surroundings. Not even my coffee cup was allowed, had to clean the desk and navigate the room through the cam.
6. Playing a bit more with the command line reference could've given me some extra points. There were about five questions I wasn't sure of because the answer had commands I didn't use much. I'd recommend knowing the basic stuff by heart (listing, detailing, starting, stopping containers, listing ports, networks, services).
I believe the exam material is very precise when it says the test aimed at people with 6 to 12 months of Docker experience. I fall into that category and passed the exam with 67% (I don't think they tell us what is the grade requirement, but I assume I cut pretty close). If you are completely new, I would suggest a good deal of lab exercising.
I would also like to thank the Linux Academy team and Terrence in particular for the excelent job of guiding us through the material, it was definitely worth the time and money. While I don't think I would have passed with the course alone, it certainly helped me optimize my time while covering almost all of the themes in the test (secrets, I'm looking at you). Combined with some hands-on experience, or labs if you are entirely new, this is a great way to get certified.
