The same problem here - getting 0% for the items which just worked for me - and it was a technical fact. I would understand getting something like 40% if it was not done the way Red Hat expects - but 0% is just wrong for things which could be used for other tasks. I opened a ticket with support, they could neither explain nor comment anything. I found some people on Linkedin who passed EX380 - and all of them did it with the previous exam version for OpenShift 4.6.
I can only suspect broken logic in the estimation flow - when it stops after an incomplete item and doesn't try to check following items. But in this case, the whole exam should be either 0% or 100%.
It's certainly not unheard of that there's an issue with the validation / scoring scripts. It needs to be brought up with the exam development team, as @Lene indicated on the previous page.
I've personally had this exact problem with EX413, when I took it a few years ago. The exam had been updated right before I took it and the dev-team had made mistakes in the scoring scripts. Both of my failed attempts I had actually passed, but the scoring script marked me wrong.
Hello, I did it in the third attemp with a score of 248 (v4.10). Two objectives are scored with 0%. I have opened a ticket so that the result is checked again.
Hello, I received a dm asking me to give some tips. I can’t talk about the exam. But I will give some general tips how I learned with the course DO380 and the provided lab.
Some general things:
1. I use this command to search for specs, it's way more efficient than looking through the documentation PDFs or minimalistic UI YAML templates:
$ oc explain <something> --recursive
2. An OpenShift cluster contains resources, which can be used as examples in the tasks:
$ oc get <something> -A
$ oc get <something> -n <project name> -o yaml > example.yaml
3. Use "yaml-lint" to validate YAML files and "jq" for JSON files.
4. Hardcode this .vimrc string into your memory and use it whenever you edit YAML:
autocmd FileType yaml setlocal ai ts=2 sw=2 et cuc
5. Vim has ":retab" command, which replaces tabs with spaces. Tabs may appear when you copy/paste YAML code from the documentation. Close and re-open your yaml file, execute ":retab", close and re-open again.
I passed EX380 today, the score was 261. Got 0% for two tasks that practically, technically WORKED. Unfortunately, there is nobody to ask what was wrong. Lack of this feedback is a serious flaw in the Red Hat examination system.
